The bacteria that live in deep sea vents where no light penetrates, yet are still capable of producing their own reduced carbon are classified as chemoautotrophs.
Chemoautotrophs are the class of organisms that use inorganic chemical reactions as the source of energy to produce organic compounds by using carbon dioxide. As they live in deep sea vents or other regions where light generally does not reach, they do not use light energy instead they use the energy obtained from the oxidation of the inorganic compounds to convert carbon dioxide into the necessary organic compounds.
Photoautotrophs are the class of organisms that cannot live in areas where light does not penetrate as they require light for energy production by photosynthesis.
Photoheterotrophs and chemoheterotrophs cannot synthesize their own products and are dependent on other plants and organisms to meet their energy and nutrition requirements.

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 response mechanisms in target cells differ for water-soluble and lipid-soluble hormones?
The majority of hormones produced by the body fall into one of three categories:
lipid-derived hormones, amino acid-derived hormones, or peptide-derived hormones. The hormones generated from lipid are lipid soluble. The hormones generated from peptides and amino acids are soluble in water. A hormone's target cells each have receptors that are unique to that hormone.The target cell can be reached by the lipid-derived hormones, which bind to the receptor protein and control its activity by crossing the plasma membrane. Hormones that are water soluble, however, cannot pass the plasma membrane. These hormones first attach to the receptor on the plasma membrane's surface.
With the aid of intracellular secondary messengers like cyclic AMP, this binding of a hormone with a membrane-bound receptor starts a cascade of secondary mechanisms within the cytoplasm of the cell. These auxiliary messengers deliver and control the signal to the target cell.

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.

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:

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.
