in which of these types of environment would you be most likely to find examples of ongoing speciation? group of answer choices areas such as large plains that facilitate migration of animals areas that have a large range of altitudes, such as mountains and deep valleys areas that are species-rich areas that have undergone recent environmental disturbance or change
The environment where ongoing speciation is most likely to be found is: areas that have undergone recent environmental disturbance or change.
Speciation is the process of formation of new species. This is the result of evolution. A new species is born form an existing species due to some new adaptations or changes. The newly formed species is reproductively isolated from the ancestral one.
Environmental disturbances are the sudden changes in an area that disturbs the species of that area. This results in the loss of species. However, environmental disturbance also provides the opportunity for speciation as the surviving species need to undergo certain changes in order to keep surviving.

Make a case for which of these social periods of you feel had the most positive impact on the environment and the most negative impact on the environment . (You can choose different periods for each responses) support your answer with facts in 5 sentences
The industrial revolution is the social period that had the most positive and most negative impacts on the environment.
The most positive impact that the industrial revolution had on the environment is the increased production of goods and efficiency. People are now able to produce every type of good they require to ease their living. Lower costs, increased wealth, and availability of a large number of products are some other positive impacts of the industrial revolution.
But as the population increased, demand for natural resources also increased. This leads to the depletion of natural resources. While during the agricultural revolution or during the times of hunter-gatherers, natural resources were prominent as the population was less.
Another negative impact that the industrial revolution had on the environment is degrading the quality of air or the environment. People are now more into using natural resources and polluting them. They are not even able to maintain sustainability in the environment.

when are two populations likely to have very similar allele frequencies
Two populations are likely to have very similar allele frequency when there is no new mutation.
Allele Frequency- The incidence of a gene variant within a population is represented by the allele frequency. Alleles are different versions of a gene that share the same genetic locus on a chromosome.
Due to the following reasons allele frequencies are stable over time, when:
No new mutation rate exists. There is no selection against any specific genotype; all individuals, regardless of genotype, are equally capable of mating and passing on their genes.As per Hardy-Weinberg equilibrium, which is known to alter allele frequency in populations, depends on five different factors.

How do cells use energy?
a, biosynthesis of more complex molecules
b. atp hydrolysis
c. cellular movement
d. active transport
Cells use energy in the following processes: a.biosynthesis of more complex molecules, c. cellular movement, and d. active transport
The biosynthesis of more complex molecules is an anabolic process. An anabolic process can be described as a process in which energy is required. For the synthesis of complex molecules, energy is derived from the nutrients that we take. Hence, biosynthesis of more complex molecules requires energy.
Any type of cellular movement that occurs against the concentration gradient requires energy. Hence, cells use energy for cellular movement.
We can describe active transport as a process in which molecules move across the cell membrane against the concentration gradient i.e from a region of lower concentration to a region of higher concentration. Hence, cells also use energy for active transport.
The process of hydrolysis, however, does not require energy. ATP hydrolysis yields energy, it does not use energy. Water is used to break down ATP to yield energy from the process of ATP hydrolysis.

How are the structures of a GPCR and an RTK similar? How does initiation of signal transduction differ for these two types of receptors?
Cell signaling is the process that happens in the cell when the receptors on the cell's surface detect a sort of stimulus, whether it is physical or chemical in nature.
The receptor will provide a conduit for these signals to enter the cell and be processed. After binding with the ligand, the G protein-coupled receptors (GPCR) and the protein-tyrosine kinase receptor (PTKR) are present on the cell's surface to form pathways for signal transmission.
The following are the differences in the responses of these two receptors:
The response of a GPCR to a ligand causes this receptor to activate a protein known as the G protein. In contrast, binding of the ligand to the receptor tyrosine kinase causes it to form dimers with another receptor, resulting in tyrosine kinase enzyme activity.The GPCR activates the protein by tethering it to GTP via a guanine exchange factor protein. The tyrosine kinase receptor, on the other hand, requires ATP hydrolysis to activate the enzyme.To learn more about signal transduction for GPCER and RTK. Click, https://brainly.com/question/15093633

Suppose you were studying two groups of obese people with genetic abnormalities in the leptin pathway. In one group, the leptin levels are abnormally high; in the other group, they are abnormally low. How would each group's leptin levels change if they ate a low-calorie diet for an extended period? Explain.
If a group has excessively high levels of leptin, the group will be determined to have poor leptin sensitivity and should turn off leptin synthesis once fat reserves are depleted. Leptin levels will fall regardless of food intake in the other group of people with low levels because they are determined to be faulty in responding to leptin.
How leptin causes obesity?Adipose tissue produces the hormone leptin, which controls body fat percentage and suppresses appetite. Leptin levels drop during fasting as adipose tissue levels drop and appetite levels rise.Leptin regulates energy balance by influencing the satiety center in the hypothalamus, and leptin deficit in the leptin signaling pathway is what leads to obesity. By communicating satiety to the hypothalamus and lowering calorie intake and fat storage, leptin plays a significant role in obesity.When there is weight loss and a decline in the leptin hormone, leptin aids in promoting a ravenous hunger and consumption of dietary food. Leptin suppresses appetite while ghrelin, a hormone released by the stomach wall, promotes appetite.When the body is thin, the level of the hormone leptin, which suppresses appetite, is lower than when the body is fat. It has a more significant impact on how many calories someone burns and how much food they consume, which in turn helps regulate how much fat tissue is stored.Learn more about the Leptin with the help of the given link:
