A
Option 1
B
Option 2
с
Option 3
D
Option 4
No
Answer:
The correct answer would be option 4
The interactions are dependent on the plant's ability to respond to the direction of light Photosynthesis.
What is Photosynthesis?Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen (O2) and chemical energy stored in glucose (a sugar).
Consequently, herbivores get this energy from consuming plants, and carnivores get it from eating herbivores.
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Therefore, The interactions are dependent on the plant's ability to respond to the direction of light Photosynthesis.

How do scientists learn about the age of the solar system and its planetary bodies? Select the two correct answers.
a. comparing the composition of the gaseous planets to the rocky planets
b. using radiometric dating of meteorites
c. measuring distances between planets
d. analyzing impact craters on planetary body surfaces
Answer: B, C
Explanation: Scientists use radiometric dating of meteorites and analyze the impact craters on planetary body surfaces to learn about the age of the solar system and its planetary bodies.
Using radiometric dating of meteorites and analyzing impact craters on planetary body surfaces are the two methods that tells us about the age of solar system.
The age of solar system and its planetary bodies can be find out by using radioactive dating techniques. Scientists have find out that the Solar System is 4.6 billion years old due to this technique. The other way to find out the age of solar system and its planetary bodies by counting the number of impact craters occurs on planetary body surfaces so these two methods provides information about the age of solar system and its planetary bodies

Three specific anatomical structures that make monkeys special or at least different and successful in its natural environment.
Answer:
Monkeys unlike most mammals (besides humans) have imposable thumbs which helps them to climb trees and open nuts and fruits.
Monkeys also have powerful tails which they use to hang on branches and to assist them in balance.
Along with imposable thumbs and strong tails, monkeys have long and flexible legs and arms which makes it easy for them to get around and climb trees.

How is a polar molecule different from a nonpolar molecule?
A.polar molecules have charges separated like poles of a magnet.
B. Polar molecules have charges evenly distributed across their poles.
C. Polar molecules are attracted to the lipids of the phospholipids of the plasma membrane.
D. Polar molecules are always larger than nonpolar molecules.
Answer: I think its b
Explanation:
if not a
A polar molecule is different from a nonpolar molecule in the fact that a polar molecule has charges separated like the poles of a magnet. Thus, the correct option for this question is A.
What is a Polar molecule?A polar molecule may be defined as a type of molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. For example, water is an example of a polar molecule.
Being a polar molecule, water is separated by a positively charged hydrogen atom and a negatively charged oxygen atom. Polar molecules are asymmetric in nature and significantly contain lone pairs of electrons on a central atom or atoms with different electronegativities bonded together.
Non-polar molecules are symmetric with no unshared electrons. These molecules have resulted from an unequal distribution of electron density.
Therefore, polar molecules have charges separated like the poles of a magnet. Thus, the correct option for this question is A.

Low genetic variation or a lack of genetic diversity increases the risks of extinction. Scientists have observed this in cheetah populations. Captive feline cheetahs at a breeding colony for large cats were exposed to a viral pathogen that killed roughly 50% of the cheetah population. None of the lions in the large cat population developed symptoms or were affected. Scientists know that lions have a more extensive genetic variation, which means they had the gene variations in their immune system necessary to fend off the disease. Describe the evidence that supports how the cheetah population is likely experiencing a lack of genetic diversity. Suggest one way humans can intervene to increase genetic diversity. Predict a potential adaptation that could result from this increase in diversity. (Please be longer than a few sentences)
Answer:
Because the pathogen killed off 50% of the population that means half of the population was susceptible to the disease, meaning that genetic variation is incredibly low because 50% of the species is the same. Humans can fix this by interbreeding cheetahs with different traits, or even breed them with a different species that is compatible for reproduction.
Explanation:
Half of the population was susceptible to the disease since the pathogen killed off 50% of the population, which means that genetic variation is extremely minimal because 50% of the species are the same.
What is genetic diversity?Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition.
It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity.
A group that is genetically homogeneous and exposed to a new pathogen without the gene variant to stop the disease could go extinct.
By performing a skin graft surgery where a portion of skin from a donor cheetah is given to a recipient cheetah, which is easily accepted if it is an inbred population, evidence to support the loss of genetic diversity of the cheetah population can be gained.
By implementing captive breeding programs, encouraging females to breed with various males in order to produce offspring with various traits, protecting the natural habitat, fostering coexistence of the cheetah species with other species and humans.
Also reducing competition for the same food source, we as humans can take action to increase the genetic diversity in the cheetah population.
Thus, these are the evidence that supports how the cheetah population is likely experiencing a lack of genetic diversity.

Sexual and asexual reproduction allow for transfer of genetic material to offspring. Which
of the following is true regarding how asexual reproduction differs from sexual
reproduction?
1.Asexual reproduction is for changing environments, sexual reproduction is for stable
environments
2.Asexual reproduction produces genetically identical offspring; sexual reproduction
produces genetically different offspring.
3.Meiosis is a form of asexual reproduction; mitosis is a form of sexual reproduction
4.Asexual reproduction is for plants; sexual reproduction is for animals,
answer: asexual reproduction produces genetically identical offspring; sexual reproduction produces genetically different offspring
explanation:
asexual reproduction is when a single organism uses its own DNA as a template to create another organism (through binary fission, fragmentation, budding, etc.) that is genetically identical
sexual reproduction is when two organisms create a combination of DNA (through a mixing of genes during meiosis, reproduction, etc.) to create an organism that is genetically different

Which is a difference between plant and animal cells?
A) An animal cell can produce energy, because if has mitochondria.
B) A plant cell has a well defined shape, because it has a cell wall.
C) A plant cell can store genetic information, because it has a nucleus.
D) Molecules can only pass into an animal cell because it has a cell membrane.
Answer:
B. A plant cell has a well defined shape because it has a cell wall
Explanation:
When you compare an animal cell to a plant cell you can see that a plant cell has a cell wall while and animal cell only has a cell memebrane. The cell walls of the plant help the plant by providing support and keeping it's shape.
The difference between plant and animal cells is plant cell has a well defined shape, because it has a cell wall.
What are the functions of cell wall?The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.
The main functions of the cell wall are to provide structure, support, and protection for the cell. The cell wall in plants is composed mainly of cellulose and contains three layers in many plants.
The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides.
