Answer:
d. 40, B.4 unique
Explanation:
If 10 cells underwent meiosis, the result would be 40 daughter cells. This is because a cell that goes through meiosis goes through two divisions resulting in 4 daughter cells. This is because cells that undergo meiosis are gametes so they need to have half the number of chromosomes as the cells that go through mitosis.
The resulting daughter cells are unique, unlike the cells that go through mitosis. This is because the chromosomes in the cells experience something called crossing over during Metaphase I. Crossing over is when the chromosomes can swap pieces of DNA when next to each other. Cells in mitosis don't go through crossing over and are therefore identical.

Explanation:
I just did it and I got it right
Both parents are heterozygous, with one dominant allele and one recessive allele. This statement describes the genotypes of the parents.
What is homozygous and heterozygous?There are two sets of chromosomes found in human beings and the pair of alleles is known as homozygous and hetrozygous. Homozygous is defined as a particular person having two common or identical genes these are known as homozygous. Hetrozygous is defined as particular person having different alleles are known as hetrozygous.
Allele is defined as differentiation of the pattern of nucleotides at the common position on a long DNA molecule. Chromosomes are the long thread type structure present in the inner side of nucleus of plants as well as nucleus.
The main composition of chromosome is protein and DNA molecule. Chromosomes trasffers from one generation to other generation or from parents to their children and they carry genetic information.
Therefore, Both parents are heterozygous, with one dominant allele and one recessive allele. This statement describes the genotypes of the parents.

how is energy lost from from an ecosystem?
Answer:
Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. ... In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.
In a changing environment, which species will have the best chance for survival? Group of answer choices The ones that are super fast. The one with the largest population. The one with the biggest genetic variation. The one with the most intelligent individuals
Answer:
one with the largest poplation because they can cook,protect, and get supplies .
Explanation:
In a changing environment, the species which will have the best chances for survival are the one with the biggest genetic variation. Thus, the correct option is C.
What is Genetic variation?Genetic variation is the difference in DNA present among different individuals or the differences between the populations. The multiple sources of genetic variation include mutations and genetic recombination in species. Mutations are the ultimate source of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Variation allows some individuals within a population to adapt better to the changing environmental conditions. Because, the natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation in a population.
Therefore, the correct option is C.

Explanation:
Gregor Mendel has stated that a gene comes with two alleles. According to his law of dominance, one of the alleles called DOMINANT allele is capable of masking the phenotypic expression of another allele called RECESSIVE allele.
In this question involving a seed color gene, which has two alleles Y and y. Y, which represents the dominant allele codes for the YELLOW trait while y, which represents the recessive allele codes for the GREEN trait. Therefore, a plant with Yy will have YELLOW SEEDS because the dominant allele (Y) is present.

How is a cell's cytoskeleton like the girders and
beams of a warehouse?
Cytoskeleton helps the cells to maintain its shape and size, due to this they are like the girdles and beams of a warehouse.
• A composition within the cell, which helps the cell to maintain their internal organization and shape is known as the cytoskeleton.
• It also provides mechanical support, which allows the cells to perform essential activities like movement and division.
• In the eukaryotes, the cytoskeleton within the cell is formed of filamentous proteins.
• The three prime classes of elements, which differ in size and in composition of protein forms the cytoskeletons.
• These are microtubules, actin filaments, and intermediate filaments.
Thus, due to the properties of the cytoskeleton, they can be considered as the girders and beams of a warehouse.

A. all molecular movement stops.
B. molecules move from areas of lesser concentration to areas of greater
concentration
C. sugar molecules move into a cell.
D. molecules move from areas of greater concentration to areas of lesser
concentration.
Answer:
d
Explanation:
The process of diffusion occurs when molecules move from areas of greater concentration to areas of lesser concentration. The correct option is D.
What is diffusion?The movement of essential, small molecules across the cell membrane as well as the movement of materials within cells both depend on the process of diffusion.
The exchange of gases in the lungs and gills is regulated by this process. As a byproduct of biological metabolism, carbon dioxide is released by all cells.
For example, when you pour a red color drop into the water, slowly the color molecules are evenly distributed in the whole water. It does not need any energy because it works according to the concentration gradient.
Thus, the correct option is D. molecules move from areas of greater concentration to areas of lesser concentration.

Which of the following describes an ADP molecule?
Answer:
The correct answer is -
ADP has less potential energy than ATP
ADP can be created when an ATP breaks or releases a phosphate bond.
Explanation:
ADP is adenosine diphosphate which means adenosine bound with a sugar molecule and two groups of phosphate molecules that also play an important role in cellular energy flow like ATP.
In ATP, there are three phosphates and two high energy bond that provides much energy in breaking whereas, in ADP, only one high energy bond and two phosphates present there.
When an ATP molecule breaks or releases one of its Phosphoanhydrous bonds and release energy and one of the phosphate groups, adenosine diphosphate or ADP created.
A student wants to shorten the ripening time for tomato plants. He predicts that the more water the plants receive,the faster they will ripen. To test this prediction,he grows 20 tomato plants in a garden in full sunlight that has dry soil and 20 tomato plants in a garden with a shadier location where there is greater moisture content in the soil. He then records the time it takes for fruit to develop and ripen on the plants in each garden location. State a serious error the student made with the design of the experiment. State all the constants in the problem.
Answer:
Explanation:
The major problem with this experiment is that he should have had a constant variable (in the form of the surrounding temperature) for his groups. Meaning, he should have had both groups planted in full sunlight and/or a shadier location since his prediction was on water intake by the plant and not the surrounding temperature.
The independent variable here is the type of soil (moist and dry) used while the dependent variable here is the time it took the fruit to develop and ripen on the plants in each garden location.
NOTE:
Independent variable can be described as the variable that is not dependent on any variable in the course of an experiment. It is also changed by the researcher during the course of the experiment.
Dependent variable can be described as the variable that is been tested during the course of the experiment.

1)What is it about the structure of ATP that contributes to its ability to act as an energy currency?
2)When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?
Answer/Exlanation:
1) ATP (adenosine triphosphate) can be hydrolyzed such that it loses a phosphate group to form ADP (adenosine diphodphate). This is called ATP hydrolysis. This property allows ATP to act as energy currency because ATP hydrolysis releases the energy stored in the high energy phosphate bond.
2) Transporting molecules against their concentration gradient requires energy. When ATP loses its phosphate group, it can phosphorylate another molecule. This converts the molecule into its active state, giving that molecule the energy to pass through against the concentration gradient.
1) The ability of the ATP compound structure to act as an energy currency has been explained in the answers.
2) The method used by ATP to allow protein transport molecules against their concentration gradient has been explained below.
1) ATP is an acronym that stands for Adenosine triphosphate. This compound called ATP is divided into three phosphate groups with phosphate bonds that possess very high energy. Now, when water is added to ATP, the phosphate bonds that possess high energy will be broken down thereby releasing energy and producing adenosine diphosphate (ADP).
2) We saw above that when ATP undergoes hydrolysis, the phosphate bonds are broken down to form ADP and releases energy. However, it can undergo further phosphorylation to form another molecule which becomes energized when it goes to a higher energy state.
Now, In this higher energy state it gets to, it will be observed that the protein will possess enough energy to transfer molecules against a concentration gradient that requires energy.

1.) What could happen if you remove an organism from a food chain?
2.) What is biodiversity?
3.) Why is biodiversity important in an ecosystem?
Answer:
1. every organism on the food chain will be affected. the ones below it will have a higher population, and the ones above it will have a lower population.
2. biodiversity is the idea, that all life is different, and environments thrive with it.
3. biodiversity is important in an ecosystem because if you take out biodiversity, you essentially take out all the animals in the given ecosystem.
Explanation:
1. when you remove lets say a spider from a food chain, the bugs that it would've eaten will start growing in population from not being eaten by the spiders. the birds that wouldve eaten the spiders, will decrease from the lack of that food source.
2. is self explanatory
3. if you only had one type of bird in one ecosystem, and that was the only animal in that ecosystem, the birds would all die, because they wouldn't have anything to eat, and nothing would eat it, so they might resort to cannibalism, or, as earlier stated, they would die off, from lack of food. the ecosystem would not be sustainable.

Explain how the binomial numendature works ?
And please put an answer that makes sense
Thank you
Btw it’s science
Answer:
Binomial nomenclature is basically the scientific classification of organisms, or taxonomy, using a latin name. It uses the genus and the species. For instance, the bacteria Staphylococcus aureus uses binomial nomenclature because Staphylococcus is the genus, while aureus is the species.
Biology Dictionary states, "The genus name is also called the generic name and always begins with a capital letter. For example, binomial name for cats is Felis catus. The genus name must be unique within each kingdom (see image below) but the same genus can be used in more than one kingdom. [. . .] The species within the genus is known by other names depending on the discipline. For general usage, the species is also called the specific descriptor. In botany, it is called the specific epithet and specific name in used in zoology. A species name can be used more than once within a kingdom.The species name always begins with a lower case letter. It can be a noun or an adjective and it must agree with the Latin gender of the genus name; masculine, feminine or neuter. For example, if the gender of the genus is masculine, the species name should end in -us, -a or -um. An example of this is Passer domesticus, the house sparrow, in which Passer has a masculine gender. Endings for feminine species names include -is and -e and -or is used for neuter genders."
