What is Jeannie showing with the dark lines inside each cell?

Answers

Answer 1

Anything that can be seen inside the nucleus of a cell. Proteins and DNA are organised into genes, which form a chromosome.

What are chromosomes and how many are there?

Chromosomes—threadlike structures made up of protein and a single DNA molecule—are used to carry genetic information from cell to cell. Chromosomes are housed in the nucleus of cells in both plants and animals, including humans.

Each cell normally has 23 pairs of chromosomes. Chromosomes, according to Sutton and Boveri's Chromosomal Theory of Inheritance, are the means by which genetic inheritance is conveyed. Rather, chromosomal behaviour includes segregation, independent assortment, and, on rare occasions, linkage; neither Mendelian genetics nor gene linkage are completely true.

Question You borrow $3200 to buy new kitchen appliances. The simple interest rate is 5%. You pay the loan off after 4 years. What is the total amount you paid for the loan?

Answers

Answer:

The total amount paid for the loan can be calculated as follows:

Total amount = Principal + Interest

Where Principal is the amount borrowed, and Interest is the additional amount charged for borrowing the money.

Given:

Principal (P) = $3200

Interest rate (r) = 5% = 0.05 (as a decimal)

Time (t) = 4 years

Using the simple interest formula:

Interest = P × r × t

Interest = $3200 × 0.05 × 4

Interest = $640

Therefore, the total amount paid for the loan is:

Total amount = $3200 + $640

Total amount = $3840

Hence, the total amount paid for the loan is $3840.

Stefan says that asexual reproduction is always better for a species than
sexual reproduction. Is he correct? Why or why not?

Answers

Answer:

Stefan's statement that asexual reproduction is always better for a species than sexual reproduction is not entirely correct. Both asexual and sexual reproduction have advantages and disadvantages, and the choice between them depends on various factors.

Asexual reproduction can produce offspring quickly, and a single individual can produce many offspring. Asexual reproduction also allows for the reproduction of organisms in stable environments where there is little genetic diversity needed. However, asexual reproduction does not provide genetic diversity in the offspring, which can lead to a lack of adaptation to changing environments and increased vulnerability to diseases and parasites.

Sexual reproduction, on the other hand, produces offspring that have greater genetic diversity, which can increase the adaptability of a species to changing environments. Sexual reproduction also allows for the elimination of harmful mutations and the recombination of beneficial genes, which can increase the fitness of offspring. However, sexual reproduction requires two individuals and is slower than asexual reproduction.

Therefore, the choice between asexual and sexual reproduction depends on the environment, the species, and the circumstances. In some cases, asexual reproduction may be advantageous, while in others, sexual reproduction may be more beneficial for the survival and success of a species.

Explanation:

Solution

Sexual mode of reproduction is considered to be better than the asexual mode of reproduction. This is because, in asexual reproduction, the only single parent gives rise to another offspring which is exactly similar to the parent as it passes its genetic material to the offspring. So, there are no chances of inducing variations in progeny and so their environmental adaptability remains low. In the sexual mode of reproduction, there are fusion gametes of two parents, male and female. As a result, the offspring has the genetic material of both, and so there is greater variation among the offsprings. They are better suitable and adaptive to their environment due to variations introduced in them during meiosis cell division and crossing over. So they are more suited to the environment they live in. So, organisms born through the sexual mode of reproduction are the better and sexual mode of reproduction is better than the asexual mode.

A. What are two ways the climate has changed since the Mesozoic? (6 points)
B. What is one way vegetation has changed since the Mesozoic? (3 points)

Answers

Answer:

A. Two ways the climate has changed since the Mesozoic are:

Cooling: The average temperature of Earth has decreased significantly since the Mesozoic era, particularly during the Cenozoic era. This cooling was caused by a decrease in atmospheric carbon dioxide levels, changes in ocean circulation patterns, and other factors.

Increased variability: The climate has become more variable and unpredictable since the Mesozoic era, with more frequent extreme weather events such as droughts, floods, and hurricanes. This may be due to changes in ocean and atmospheric circulation patterns, as well as human-induced climate change.

B. One way vegetation has changed since the Mesozoic is:

Evolution of flowering plants: During the Mesozoic era, the dominant plant species were gymnosperms such as conifers and ferns. However, during the Cenozoic era, flowering plants (angiosperms) became the dominant plant species. This change in vegetation may have been driven by the evolution of new pollination strategies and adaptations to changing climate conditions.

Answers

The correct answer is: 92, 46, 23.

At the beginning of meiosis I, the cell contains 92 chromosomes, since it has already undergone DNA replication during interphase. During meiosis I, the homologous pairs of chromosomes separate, resulting in two daughter cells, each containing 46 chromosomes.

During interkinesis, which is a brief resting period between meiosis I and meiosis II, the chromosomes briefly decondense and the cells prepare for the next division.

During meiosis II, the sister chromatids of each chromosome are separated, resulting in four daughter cells, each containing 23 chromosomes.

How could you investigate the lowest possible effective dose to use against a particular strain of bacteria

Answers

Stimulations were ran to examine the effects of changes in dosage distribution and antibiotic exposure frequency on community resistance patterns.

What are Antibiotics ?

Antibiotics are antimicrobial substances that are active against microorganisms. Antibiotic drugs are widely utilized in the treatment and prevention of bacterial infections since they are the most significant form of antibacterial agent. They can either kill or hinder bacterial growth. A small proportion of antibiotics have antiprotozoal action. Antibiotics are ineffective against viruses such as the common cold or influenza; instead of antibiotics, medications that decrease virus growth are referred to as antiviral drugs or antivirals. They are also ineffective against fungi; antifungal medicines are those that hinder the growth of fungus.

What is Antibiotic resistance ?

Antibiotics are antibiotics that are used to prevent and treat bacterial infections. Antibiotic resistance arises when bacteria adapt to the usage of these medications. Antibiotic resistance develops in bacteria rather than people or animals. These bacteria can infect humans and animals, and their infections are more difficult to treat than infections caused by non-resistant bacteria.

Antibiotic resistance raises medical expenses, lengthens hospital stays, and increases mortality.

The world urgently needs to modify the way antibiotics are prescribed and used. Even if new medications are found, antibiotic resistance will remain a big threat unless behavior changes. Changes in behavior must also include efforts to minimize the spread of illnesses such as immunization, hand washing, safer sex, and excellent food hygiene.

What would be the difference in a mistake in the DNA of a body cell, such as a brain cell, vs. a mistake in the DNA of a germ cell that would eventually make a sperm cell?

Answers

Answer:

A mistake in the DNA of a body cell, such as a brain cell, would only affect that particular cell and its daughter cells produced through mitosis. This is because DNA mutations occurring in body cells are not passed on to offspring during reproduction.

In contrast, a mistake in the DNA of a germ cell, such as a precursor cell that eventually develops into a sperm cell, can be passed on to the offspring during reproduction. This is because germ cells undergo meiosis to form gametes (sperm or egg cells), and any mutations in their DNA can be passed on to the next generation.

Therefore, mistakes in the DNA of germ cells have implications for the genetic makeup of future generations, while mistakes in the DNA of body cells only affect the individual organism in which they occur.

how are mutation and sexual reproduction involved in creating and maintaining variation in a population? answer in simple terms

Answers

Answer:

Mutation and sexual reproduction are the two main ways that variation is created and maintained in a population. Mutations are random changes in the genetic code of an individual, which can lead to new traits that were not present before. Sexual reproduction involves the combination of genetic material from two individuals, which can create unique offspring with different traits than either parent. These two processes work together to increase the genetic diversity within a population, which is important for adapting to changes in the environment and for the survival of the species over time.

Explanation:

In sexual reproduction, gametes receive a random assortment of genetic information from their parents, which creates unique genetic combinations in the offspring.


These new genetic variations can result in new traits, some of which may be beneficial, harmful, or neutral. Natural selection can effect these traits, causing the amount of beneficial traits to increase in the population, with the opposite happening for harmful traits.

Mutations in sexual reproduction are important for creating and maintaining genetic variation in a population, otherwise evolution would not occur.

Geodesy, the science of measuring the Earth's shape and positions on it, allows the measurement of plate motion directly using GPS, the Global Positioning System. This network of satellites is more stable than the Earth's surface, so when a whole continent moves somewhere at a few centimeters per year, GPS can tell.


Without access to the Plate Motion Sim, I cannot provide you with the specific measurements to fill out the data table. However, I can provide guidance on how to complete the task based on the instructions provided.

To measure how far plates move from each other over time, you will need to add a GPS marker to each plate as close as possible to each other and to the plate boundary. Then, you will need to set the boundary to Divergent and run the simulation.

During the simulation, you will need to press Pause approximately every 50 million years and record the time in the first column of the table. Next, observe the distance between the two pins by pressing on either pin and reading the distance to the other. Record that number in the Distance column.

To calculate the rate for each pair of distances and times, you will need to divide the distance by the time. Record those numbers in the Rate column. Finally, you can use the data to analyze the speed at which plates move and draw conclusions about plate tectonics.

Final answer:

Non-algae plants in the ocean, particularly seagrasses and mangroves, provide critical habitats for marine species, improve water clarity, protect coastal areas, and prevent erosion.

Explanation:

Non-algae plants in the ocean, specifically seagrasses and mangroves, play vital roles in marine ecosystems. Seagrasses provide a habitat for many marine creatures including fish and invertebrates, acting as a nursery ground for young organisms. They also contribute to water clarity by helping to bind the sediment.

Mangroves, on the other hand, act as a buffer zone protecting the coastal areas from strong waves and winds. They prevent erosion and contribute to the stability of the shoreline. Mangroves is also a critical habitat for various forms of wildlife and serve as a breeding ground for a multitude of marine species.
