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.
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 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.

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.

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.
Two atoms have the same number of protons but different numbers of neutrons. These atoms are:
A. electrons
B. isotopes
C. molecules
D. radiation
tysm!
Answer:
Isotopes
Explanation:
If two atoms have different numbers of protons, they are different elements. However, if two atoms have the same number of protons, but different numbers of neutrons we refer to them as isotopes. Two terms we use to identify nuclides (isotopes) are atomic number and mass number.

describe a specific exmaple of postive action that reduce human imapct on land?
Answer:
Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and out-going infrared (thermal) radiation that are part of Earth’s energy balance. Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system. Since the start of the industrial era (about 1750), the overall effect of human activities on climate has been a warming influence. The human impact on climate during this era greatly exceeds that due to known changes in natural processes, such as solar changes and volcanic eruptions.

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.

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).

Whích statement is best supported by the diagram?
А.
Species T and Species U are related to species X
B. Species X evolved later than Species U but before Species s.
С.
Species T is the ancestor of Species S.
D
Species U and V evolved from Species S.
Answer:
4
Explanation:
The statement that is best supported by the image is that species T and species U are related to species X.
What is evolution?Is the gradual development of new forms of organisms from their ancestral forms.
In the image, X is the ancestor of T, U, V, and S. Thus T, U, V, and S are related by common ancestry.
Thus, it is correct to say that T and U are related to species X.
However, it is incorrect to say that X evolved later or species U and V evolved from S.
