Answer:
Hardy-Weinberg equilibrium
Explanation:
The Hardy-Weinberg law is established in it is that in a sufficiently large population, in which the matings occur randomly and that is not subject to mutation, selection or migration, the gene and genotype frequencies remain constant from generation to generation, once a state of equilibrium has been reached that is reached after one generation at autosomal loci. A population is said to be in equilibrium when alleles from polymorphic systems maintain their frequency in the population through generations.

3.What are the functions of vacuoles, lysosomes, and the
cytoskeleton?
Answer:
In plant cells, vacuoles maintain water balance. Lysosomes break down excess or worn-out cell parts. The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.
Explanation:
Storage, waste disposal and structural support are the functions of vacuoles, lysosomes, and the cytoskeleton.
The following are the roles of vacuoles, lysosomes, and the cytoskeleton: Vacuoles are membrane-bound organelles that can be found in the cells of fungus, protists, and plants. They serve a variety of purposes, such as: Vacuoles have the capacity to store a wide range of materials, including waste materials, pigments, water, and nutrients. They control the osmotic equilibrium and aid in maintaining turgor in plant cells. Vacuoles in plant cells can be used as a storage space for a variety of waste materials and poisons that are damaging to the cell. They keep these molecules apart and stop them from harming other cell components. Support for structure: In plant cells, the huge central vacuoles press on the cell wall to support structure and preserve the form of the cell. Lysosomes are membrane-bound organelles that can be found in cells.

Which statements about geocentric model and heliocentric model are true? Select the two correct answers.
A. They both are models of the solar system.
B. They both show the position of Earth relative to the Sun.
C. They both show Earth at the center of the solar system.
D. They both show the Sun at the center of the solar system.
Answer: Your correct answer would be both A & B.
Explanation: A is the correct answer because both of these models are in fact models of our solar system. The geocentric model had Earth at the center of the solar system with all the other planets and sun rotating around us. The heliocentric model is the accepted model of our solar system today with the sun at the center and planets rotating in slightly elliptical fashions around it due to gravitational pull. B is also correct because as I just explained, both models position Earth in relativity to the sun though both models vary greatly. The aim of both of these models was to specify where Earth was exactly in the solar system. I hope this has been of use to you! Please do not hesitate to ask if you have other questions :)
The two correct statements about the geocentric and the heliocentric model are:
They both show the position of Earth relative to the Sun. They both are models of the solar system.The geocentric model
The geocentric model has the assumption that the earth is at the center of the universe. The sun and the planets are said to revolve around the earth in this model
The heliocentric model:
The heliocentric model has the assumption that the sun is at the center of the universe. The earth and the planets revolve around it.

A moth's color is controlled by two alleles, G and g, at a single locus. G (gray) is dominant to g (white). A large population of moths was studied, and the frequency of the G allele in the population over time was documented, as shown in the figure below. In 1980 a random sample of 2,000 pupae was collected and moths were allowed to emerge. Assuming that the population was in Hardy-Weinberg equilibrium for the G locus, what percentage of the gray moths that emerged in 1980 was heterozygous? (The Answer is 67%, can you please explain why it's 67%? thank you!!)
Answer:
67%
Explanation:
When taking random samples from a population, the observed numbers are not always as the expected ones. The difference is by chance, instead of 50% heter0zyg0us, the sample included 67%.
--------------------------
Available data:
- Moths' color ⇒ diallelic gene
G allele → dominant → Codes for greyg allele → recessive → Codes for white- f(G) 1960 = 0.8
- f(G) 1965 = 0.7
- f(G) 1970 = 0.6
- f(G) 1975 and 1980 = 0.5
- 1980 ⇒ N = 2000 pupae
- Population in H-W equilibrium
Hardy-Weinberr equilibrium,
Assuming a diallelic gene, p and q are the allelic frequencies in a locus and represent the allelic d0minant or recessive forms. The gen0typic frequencies after one generation are p² (H0m0zyg0us d0minant), 2pq (Heter0zyg0us), q² (H0m0zyg0us recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation.When adding the allelic frequencies of a population in H-W equilibrium, the result should be 1, this is p + q = 1.In the same way, when adding the genotypic frequencies, the result should also equal 1, this is p²+ 2pq + q² = 1In this problem we assume that the population is under H-W equilibrium, and we know that p = 0.5.
Considering that p + q = 1, then by clearing the equation, we get the value of q = 0.5
Finally, we know that the genotypic frequency of the heter0zygous genotype is 2pq, so,
F(Gg) = 2pq = 2 x 0.5 x 0.5 = 0.5 = 50%
Now, among the options in the problem, there is not 50% but others. One of them, and the closest to 50%, is 67%.
The chart reflects that through the years, the moth's populations stabilized. Both alleles were favored, and their frequencies got to be equal to each other -0.5-. So there is a high probability of getting heter0zyg0us individuals in the population -50%-, more than any of the h0mzyg0us ones -25%-.
However, in a natural population, the amount of h0m0zyg0us and heter0zygous individuals observed is not always the same as the expected ones. This fact happens especially when there are random samples.
In this experiment, the researcher took 2000 pupae, but they did not know their genotype. They just took them randomly. Even though the population is in H-W equilibrium, when sampling, the researcher took more heter0zyg0us individuals than the expected ones. It does not mean that the population is not under H-W equilibrium. It just means that by chance, more heter0zyg0us were selected.
So what you need to do in these situations, is to analyze your problem and the provided information, and think about the most feasible answer.
In this case, the expected number is 50% heter0zyg0us. The closest option is 67% and the most feasible. So that would be the answer.

Which of the following explains why geological events occur?
a The lower mantle is solid rock
b The crust is the same thickness throughout
c The crust is a single layer throughout
d The lower mantle is hotter
Answer:
Hey there,
The answer is A.
This is because the crust is broken into parts called plates and these plates collide with each other or separate from each other or slide past each other.
They move because they sit on top of semi molten rock in the mantle. The semi molten rock moves due to convection currents which is heated up by the core.
It’s is not option B because it does not have u form thickness through out it. For eg the continental crust is 60 km thick while the oceanic plates are wonly 10km thick.
It is not C as the mantle is semi molten not solid.
And it’s not D because it’s not a single layer but multiple layers.
So A is the answer.

Explanation:
What structures allow each protist to move?
Amoeba:
Euglena:
Paramecium:
Amoeba moves using pseudopodia.
Euglena moves using flagellum.
Paramecium moves using cilia.
What are the structures that allow the movement in different protists?
Pseudopodia, or protruding portions, are used by amoebas to move. Its meaning is "false feet." These are membrane elongations of the cell. With its pseudopod, an amoeba can reach out and grab a surface, using it to propel itself forward.Flagellums (plural flagella), a long whip-like structure that functions as a little motor, help euglena move. On the anterior (front) end, the flagellum spins in order to propel the cell through the water.Cilia have the ability to move in unison to advance a Paramecium. When a barrier is reached, the cilia travel in the opposite direction, somewhat reversing the Paramecium's forward motion.

⦁ What is the purpose/function of the Respiratory System?
⦁ What is the purpose of the tiny hairs called cilia in your nose?
⦁ What are the purposes of the pharynx?
⦁ What is the purpose of the epiglottis?
⦁ How is the respiratory system linked to the cardiovascular system
Answer:
1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .
2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body
