Answers

Answer 1

Answer:

A. The wild population, because it is more likely to contain some plants that are resistant to the fungus.

The genetic diversity of the wild population means that there is a higher likelihood that at least some of the plants will have natural resistance to the fungus. This means that even if the fungus is harmful to most of the plants, the resistant plants will survive and reproduce, passing on their resistance to future generations. In contrast, the crop population, which has lower genetic diversity, is more susceptible to being wiped out entirely by the fungus.

Answer 2

Answer:

A

Explanation:

the more variations, the more options, and therefore the higher the chance that they include some to fight a threat.

this also happened with the human race and e.g. the bubonic plaque and also with the cold, the flu and Covid.

only people with certain genetic markers survived and then reproduced.

if for some reason the bubonic plaque would break out again, and we would not have the antibiotics against it, still it would kill much less of the population than back in medieval times, as we all are descendents from the survivors back then (and carrying mostly their genetic markers) .

and because of the natural selection during the Spanish flu pandemic, the flu and Covid (as a close relative to flu and cold) are today mostly an annoyance and not a deadly threat to the general population. all of them still kill a lot of people, don't get me wrong, but it is still a tiny fraction of the population.

when the western civilization brought the common cold to the Inuit ("Eskimos"), it almost annihilated them completely, as they were not used to such a virus. but luckily at least some of them had the necessary genetic markers, and so they survived. and today it is the same "annoyance" to them as it is to the rest of the world

Covid only got the big headlines, because it killed more than the usual "share" from the risk groups (old and already sick), and concentrated its "efforts" on complex lung infections but also blood infections that caused a dangerous drop of oxygen levels in the blood, which caused the higher than usual hospitalization rates.

immunization by vaccination helped a lot with flu and Covid, but that does not (or very little) help with the natural immunization of future generations, because still everybody reproduces, and not just the ones with the necessary genetic markers to defeat these infections.

A. How do scientists think Earth's orbit relates to an Ice Age? (2 points)
B. What is precession? (1 point)
C. How is precession related to an Ice Age? (2 points)

Answers

Answer:

A. Scientists think that Earth's orbit can play a role in the onset of an ice age because it affects the amount of solar radiation that reaches different parts of the Earth's surface. Specifically, variations in Earth's orbit can lead to changes in the distribution of sunlight, which can influence the temperature and precipitation patterns that are necessary for the growth and retreat of glaciers.

B. Precession is a term used to describe the slow, cyclical wobbling of Earth's rotational axis. This wobbling causes the direction that the axis is pointing to slowly shift over time, completing one full cycle approximately every 26,000 years.

C. Precession is related to an ice age because it can affect the timing and intensity of the seasons, which in turn can influence the growth and retreat of glaciers. During certain phases of precession, the Earth is closer to the Sun during the summer in one hemisphere and farther away during the winter, which can lead to more extreme temperature and precipitation patterns. These patterns can create conditions that are more favorable for the growth of glaciers, which can contribute to the onset of an ice age.

Explanation:

Why does burning fossils fuels have negative consequences for the planet?

Answers

Burning fossil fuels has negative consequences for the planet because it releases large amounts of greenhouse gases, particularly carbon dioxide, into the atmosphere.

What are greenhouse gases?

Greenhouse gases trap heat in the Earth's atmosphere, causing the planet to warm up and leading to climate change.

Climate change has far-reaching effects on the planet, including rising sea levels, more frequent and severe weather events such as heat waves, droughts, floods, and storms, and changes in the distribution and abundance of plant and animal species. These changes can lead to environmental, economic, and social impacts, such as loss of habitat, decreased agricultural productivity, and displacement of populations.

In addition, the extraction and transportation of fossil fuels can also have negative environmental impacts, such as water pollution, air pollution, and habitat destruction. The burning of coal, oil, and gas also releases other pollutants, such as sulfur dioxide, nitrogen oxides, and particulate matter, which can cause respiratory problems and other health issues in humans and wildlife.

Overall, the negative consequences of burning fossil fuels highlight the importance of transitioning to cleaner and more sustainable sources of energy, such as renewable energy sources like solar, wind, and hydropower.

2. What are two examples of how nuclear power can damage ecosystems? (10 points)

Answers

Answer:

Nuclear power has the potential to damage ecosystems in several ways, including:

Thermal pollution: Nuclear power plants require a large amount of cooling water, which is often discharged back into the environment at a higher temperature. This thermal pollution can harm aquatic ecosystems by reducing the amount of oxygen in the water, altering the water chemistry, and affecting the behavior and distribution of aquatic organisms.

Radioactive contamination: Nuclear accidents or leaks can release radioactive materials into the environment, which can harm both terrestrial and aquatic ecosystems. These materials can be taken up by plants and animals, leading to the bioaccumulation and biomagnification of the radioactive substances in the food chain. This can result in genetic mutations, reduced reproductive success, and increased mortality rates in exposed organisms.

Overall, the potential environmental impacts of nuclear power underscore the importance of implementing appropriate safety measures and considering the potential consequences before embarking on any nuclear power projects.

Aquaporins

Explanation:

AQP are integral membrane proteins that serve as channels in the transfer of water, and in some cases, small solutes across the membrane. They are conserved in bacteria, plants, and animals. Structural analyses of the molecules have revealed the presence of a pore in the center of each aquaporin molecule.

The special proteins that let water pass through them are called aquaporins.

EXPLANATION

Aquaporins are "the plumbing system for cells". Water moves through cells in an organized way, most rapidly in tissues that have aquaporin water channels. For many years, scientists assumed that water leaked through the cell membrane, and some water does. However, this did not explain how water could move so quickly through some cells.

What are the types of seeds and classes of seeds?

Answers

Answer:

Nucleus, Breeder, Foundation, and Certified.

What is a seed?

One of the ways in which a plant produces another plant of its own kind is the seed. Just as birds lay eggs to reproduce their kind, the plant grows a seed that makes another plant.

The flower or blossom of a plant must be fertilized or the seed it produces will not grow. After the seed is fully grown, or mature, it must rest. The rest period varies among different kinds of seeds. Many of them will not grow until they have rested thru the winter.

Seed growth requires moisture, oxygen, and warmth. Light helps some plants start seed growth. If seed growth doesn't start within a certain time, the seed will die. When seeds are stored by man for future use, they must be kept dry and within a certain temperature range.

Seeds vary greatly in size, shape, pattern, and color. The seeds of different plants are made in different ways. There is one kind of seed, for example, that has the tiny new plant in the center. Around this is stored food which will tide the young plant over until it has developed roots and leaves and can make its own food.

If a seed is fertile, has rested, and has received the moisture, oxygen, and warmth, it begins to grow. This is called “sprouting” or “germination.” Growth often starts when moisture reaches the seed. As the seed absorbs water, it swells. As chemical changes take place, the cells of the seeds begin to show life again and the tiny young plant within the seed begins to grow. Most parts of the seed go into the growing plant. The seed cover drops off and the new plant grows larger until it matures and makes seeds of its own.

Seeds may be small or large. Begonia seeds are so small they look like dust. Coconuts are seeds which may weigh as much as 40 pounds! Some plants have only a few dozen seeds, while others, such as the maple, have thousands. There are special ways seeds are made so that they will be spread. Burr-type seeds hitch a ride on the fur of animals. Seeds that stick in mud cling to animals feet. Seeds contained in fruit are carried by man and animals. Some seeds have "wings" and are blown by the wind, other seeds float on water, and some are even "exploded" away from the parent plant!

Based on the data, was Zack, who ate the tofu, guilty of leaving a mess in the classroom?

Answers

If reagent turned purple, Zack ate tofu and was guilty of leaving a mess; otherwise, he was not guilty.

That's what the speculation expresses in the event that the secret food is tofu, it will respond with the reagent that demonstrates the presence of a protein. In light of the information, assuming that the reagent became purple subsequent to testing the secret food that Zack ate, then, at that point, it demonstrates the presence of a protein and supports the speculation that the secret food was tofu. In this manner, Zack would be at legitimate fault for leaving a wreck in the study hall on the off chance that the reagent became purple since he was the one in particular who ate tofu. Nonetheless, in the event that the reagent didn't become purple, it implies that the secret food was not tofu or didn't contain sufficient protein to be distinguished by the reagent.

Which statement about enzymes is essential to the lock and key hypothesis ?

A. Enzyme molecules can be damaged by high temperatures

B. Enzyme molecules each have a distinct shape

C. Enzyme molecules are catalysts

D. Enzyme molecules can be damaged by high pH values

Answers

Answer:

B. Enzyme molecules each have a distinct shape.

The lock and key hypothesis suggests that enzymes have a specific three-dimensional shape that is complementary to the shape of the substrate molecule they interact with. This means that enzymes can only interact with specific substrates, just as a key can only fit into a specific lock. Therefore, the statement that "enzyme molecules each have a distinct shape" is essential to the lock and key hypothesis.

Explanation:

Answer: The essential statement that relates to the lock and key hypothesis of enzymes is B. Enzyme molecules each have a distinct shape.

Explanation: The lock and key hypothesis proposes that enzymes have a specific three-dimensional shape that allows them to bind to a specific substrate molecule in a way that is analogous to a lock and key fitting together. This hypothesis explains why enzymes are highly specific in their catalytic activity and only catalyze reactions involving specific substrates. The specific shape of the enzyme's active site is essential for the substrate to fit into the enzyme's active site and for the enzyme to catalyze the reaction. Therefore, the specificity of the enzyme-substrate interaction is essential to the lock and key hypothesis. Options A, C, and D are not essential to this hypothesis. While enzymes are catalysts and can be damaged by high temperatures or pH values, these statements do not specifically relate to the lock and key hypothesis.

Answers

The length of each cell  in the eyepiece division is option B which is  40 μm

Eyepiece division calculation.

In a microscope, the eyepiece graticule is a scale located in the eyepiece that helps to measure the size of microscopic objects. The stage micrometer, on the other hand, is a calibrated scale on the microscope stage that is used to calibrate the eyepiece graticule.

To determine the value of each eyepiece division on the stage micrometer, we use the following formula:

Value of each eyepiece division = (Value of each stage micrometer division) x (Number of stage micrometer divisions per eyepiece division)

The calculation can be done using the formula:

Length of one eyepiece division = (Length of one stage micrometer division) x (Number of stage micrometer divisions per eyepiece division)

Length of one eyepiece division = 10 μm x (16/40) = 4 μm

Since 4 cells fit across 40 divisions of the eyepiece graticule, the length of each cell is:

Length of each cell = Length of one eyepiece division x 4 = 4 μm x 4 = 16 μm

Therefore, the answer is B) 40 μm by calculating the value of each micrometer.

Why do children never look exactly identical to their parents? Use and UNDERLINE the following words in your explanation: gene, allele, chromosome.

Answers

Answer:

Children never look exactly identical to their parents because of the process of genetic inheritance. Each individual inherits one set of 23 chromosomes from each parent, resulting in a unique combination of genetic information. Chromosomes contain thousands of genes, which are the basic units of heredity that determine traits such as eye color, hair color, and height. Each gene can have different versions called alleles, which can lead to variations in the trait. The combination of alleles inherited from each parent determines the child's traits. Since each parent contributes a different combination of alleles, the child will inherit a unique combination that may differ from both parents. Therefore, the genetic makeup of each individual is unique, resulting in physical and behavioral differences between individuals.

A cross between a dihybrid individual (heterozygous for two traits) and a homozygous recessive individual for the same two traits produces these phenotypes as offspring: parental phenotypes 526 and 542, and recombinant phenotypes 22 and 24.
A. these genes are not linked

B. these genes are on different chromosomes

C. these genes are linked

D. these genes sort independantly

can someone explain why is it c

Answers

Answer:

The answer is C because the number of recombinant phenotypes is less than the parental phenotypes. This indicates that the two genes are linked on the same chromosome, and crossing over occurs less frequently between them during meiosis.

If the genes were not linked (answer A), then the expected ratio of parental phenotypes to recombinant phenotypes would be 1:1. However, we observe a greater number of parental phenotypes than recombinant phenotypes, indicating that the genes are linked.

If the genes were on different chromosomes (answer B), then they would assort independently during meiosis, and the ratio of parental to recombinant phenotypes would be 1:1.

Therefore, the correct answer is C: these genes are linked.

The Effect of Salinity

Looking at the data here, what do you think has contributed to the narrowing of the range of loosestrife in the marsh over the course of ten years?

Answers

Based on the data shown here, the increase in the salinity of the marsh has contributed to the narrowing of the range of loosestrife in the marsh over the course of ten years.

What is the effect of increasing salinity on marsh plants that thrives in the low-salinity areas of marshes?

Marsh plants that thrive in low-salinity areas of marshes such as Purple loosestrife are adapted to grow in freshwater or slightly brackish water environments. Increasing salinity can have a negative impact on these plants and their growth.

One effect of increasing salinity is that it can disrupt the balance of water and salt uptake in the roots of marsh plants. As the salt concentration in the soil or water increases, it can create an osmotic gradient that makes it more difficult for the roots to absorb water. This can cause the plant to become dehydrated, which can affect its ability to photosynthesize and grow.

Another effect of increasing salinity is that it can cause the accumulation of salt in the leaves and stems of the plant. As salt levels increase, the plant may begin to show signs of salt damage, such as leaf burn or wilting. If the salt accumulation becomes severe enough, it can even cause the plant to die.
