In a population with 100 rabbits there are 16 that are albino, with two
recessive genes for albinism. In this population, what is the gene
frequency for the albino allele?
16
16
0.4
0.84
Answer:
The gene frequency for the albino allele is 16%.
Explanation:
Given that in a population with 100 rabbits there are 16 that are albino, with two recessive genes for albinism, to determine, in this population, what is the gene frequency for the albino allele, the following calculation must be performed:
16/100 = X
0.16 = X
1 = 100
0.16 = X
0.16 x 100 = X
16 = X
Therefore, the gene frequency for the albino allele is 16%.

What changes in energy occur when the bowling ball strikes the pins?
Answer:
please give me brain list and follow
Explanation:
The bowling ball's energy of motion is about to cause a change. ... The collision with the bowling ball changes that. The ball strikes the pins, and some of the ball's energy of motion transfers to the pins. This makes the pins gain motion energy and leaves the ball with less motion energy.

describe how energy for the photosynthesis reaction is gained by plants (2)
please help
Answer:
Plzzzz answer fast......
The energy for the photosynthesis reaction is gained in the first stage of the reaction.
There are 2 stages in photosynthesis:
The light-dependent stageThe light-independent stageDuring the light-dependent stage, an electron in the molecules of chlorophyll gets excited and gets knocked off as a result of photon absorption. A molecule of water is split and the electrons released replace the one lost by the chlorophyll after traveling through the electron transport chain.
The energy from the traveling electron is used to reduce NADP+ to NADPH while the splitting of water to H and O means that a proton gradient is established between the stroma and the thylakoid lumen of the chloroplast. The electrochemical gradient thus created is used by ATP synthase to generate ATP from ADP.
The two chemicals, ATP and NADPH, are then utilized as energy sources for the light-independent reaction.

For each of the following processes, identify the part of the chloroplast in which it takes place. Light-dependent reactions Light-independent reactions Sun’s energy absorbed Sugars produced
Answer:
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).

What is the main difference between primary succession and secondary succession?
Answer:
Primary succession in the first initial establishment of an ecosystem on a new layer of terrain (usually rock), whereas secondary succession is a re-establishment of an ecosystem OR simply any establishment of an ecosystem on a rock which was previously inhabited.
Explanation:
Primary succession is the very first establishment of an ecosystem on a new layer of terrain (usually rock) which was previously uninhabited by living organisms. Secondary succession can be thought of as a re-establishment of ecosystems on a terrain/rock which was previously inhabited but is no longer due to an ecological or environmental disruption.
Hope this helped!
Answer:
Primary succession is the progress of plants growing on bare lands, like a bulldozed area, a landslide, or even a solid rock. (Or a volcano.)
On the rock, lichens start, make a little soil, mosses start in the soil, make a little more, Spikemoss (a vascular plant) starts, traps and makes more soil, making a place for dry land plants, which trap and make more soil, eventually, after a very long time, giving rise to a mature forest over rock. The only way to tell that rock is the substrate is the forest composition
Secondary is from a place that has had a forest, and is either burned, farmed, or cut. Plants start very quickly from seeds, roots, tubers, and reforestation can take as little as 20 years, and maturity as little as 75.

What’s the answer for this
A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study
Answer and Explanation:
Regarding genetics, the results of the study show that the mother's genetic material does not influence the behavior of rats in times of stress or in the biological responses of rats to these stressful moments. This is because the mice inherited their mothers' genes, but did not show the same results in a stressful situation when they were raised with different mothers.
Regarding epigenetics, however, we can see that the mothers' behavior in relation to the care of rats managed to provoke epigenetic changes that prevented or stimulated the expression of genes linked to stress, in these rats. The rats that were raised with attentive mothers showed a low expression of stress-linked genes, regardless of the biological mother they had. In addition, it is possible to notice that this modification is permanent, since the rats presented this same type of response throughout their lives.

There are different kinds of mutations. What can happened to the fruit

What takes place to the body of a fruit fly if the Hox gene is altered?When there is Homeotic mutations in fruit flies, Homeotic genes are said to be the reason or the option that is used in knowing the identity of some specific segments or structures of the body.
If an homeotic genes is said to be inactivated or when expressed in an unusual part of the body due to mutations, it may make the body segments to take on new form.

SHORT ANSWER QUESTION: Include a Claim, Evidence, Explanation, and Conclusion for full credit. Rubric is include at top of quiz.
In the past, fifty percent of jaguars in the Amazon jungle had large strong jaws and fifty percent had weak jaws. There was a change in their environment leaving only hard-shelled reptiles like turtles available for the jaguars to eat. Below is a graph showing the allele frequency in the population of jaguars over the next 5 generations.
Construct an argument based on evidence to determine which allele represents the large strong jaws and which allele represents the weak jaws.
Answer:
Allele G represents the strong jaw, and allele g represents the weak jaw. This is because as the generations go by, allele G’s population increases, but allele g’s population decreases. If hard shelled animals are the only foods available to them, you would need a strong jaw to eat them. This means that allele g wouldn’t be able to eat these reptiles, so their population would decrease from lack of food.

Why are sodium ions differentially permeable?
Answer:
In most cases, an ion channel is permeable only to specific types of ions (for example, sodium and potassium but not chloride or calcium), and sometimes the permeability varies depending on the direction of ion movement.
