Biomolecules are made from simple monomers, yet you find a very high level of diversity. What chemical features make diversity in each category of biomolecules possible?
Chemical features like 3 dimensional structure and chemical bonding are responsible for diversity in biomolecules although they are made from simple monomers.
In the case of carbohydrates, both starch and glycogen are made up of glucose monomers yet they differ in the functions which they perform in our body. This difference is because of the chemical bonding and the 3 dimensional structure.
Similarly in protein biomolecules, amino acids act as the monomers but they differ in function due to their 3 dimensional structure. Nucleotides are the building blocks of both RNA and DNA. RNA and DNA perform different functions in the body. DNA stores ad transfers genetic information while RNA is responsible for directly coding for amino acids.

Correct answer is ‘B’ .
Stabilizing selective pressures result in limited evolutionary changes
How do selective pressures affect evolution?Stabilizing selection is a type of natural selection that results in a decrease in genetic diversity and the stabilization of population traits over time.
Selective pressures are thought to be forces that drive evolution through natural selection.
Depending on the external conditions, some phenotypes are more advantageous than others.
A phenotype is a specific way that genes are expressed in an organism's physical traits or characteristics.

Why are the exact timing and nature of anagenesis and cladogenesis difficult to infer from the fossil record?
We cannot infer exact timing and nature of anagenesis and cladogenesis from fossil record because,
There are gaps in the fossil record because it is difficult to achieve the conditions needed for fossilization.In comparison to species in other habitats, creatures that dwell where sediment is actively being deposited (such as beaches and wetlands) are more likely to become fossilized. Some organisms are more likely to decompose slowly and leave fossils behind, such as those with hard features like bones or shells.What is anagenesis? One taxon replaces another without branching in a single lineage as a result of evolutionary change is known as anagenesis.What is cladogenesis?The process by which a higher taxon or new group of animals emerges through evolutionary divergence like branching from an ancestor is known as cladogenesis.What is fossil record?Paleontologists, archaeologists, and geologists use the fossil record to put significant occurrences and species in the right geologic epoch.

It decreases the amount of LH-releasing hormone in the hypothalamus and prevents the pituitary gland from producing and releasing follicle-stimulating hormone.Inhibin is a factor in the feedback control of FSH secretion in both males and females going through puberty. Follistatin suppresses FSH-subunit expression like inhibin, whereas activin enhances it, which in turn influences FSH production and secretion.Inhibin A is secreted by the corpora lutea and dominant ovarian follicles in women, which helps to explain why levels are so high during the late follicular and luteal stages.

By which proposed molecular mechanism does ca2 promote fusion of synaptic vesicles?
Through binding and inducing changes in synaptotagmin which causes the plasma membrane to curve, thus, facilitating fusion.
Ca2+ triggers synaptic vesicle exocytosis, therefore, releasing the neurotransmitters contained in the vesicles and initiating synaptic transmission. Synaptotagmin (syt) is a Ca2+ sensor which can induce fast and synchronous neurotransmitter release.
Synaptic transmission amidst pre- and post-synaptic neurons occurs when the pre-synaptic neuron terminal is temporarily depolarized upon an action potential, thereby, opening Ca2+ channels near the active zones of synapses. Ca2+ flows into the cytoplasm as the extracellular Ca2+ concentration is much higher than the cytoplasmic concentration . Successively, Ca2+ triggers fusion of neurotransmitter-filled synaptic vesicles with the presynaptic membrane in less than a millisecond.
Neurotransmitter molecules are released into the synaptic cleft upon fusion, which then bind to the receptors located in the postsynaptic membrane.
