Answer:
Having elecrical impulses travel down the axon to the terminal.
Explanation:
Whole genes and parts of genes can be extracted from chromosomes, linked to other DNA molecules to form recombinant DNA and introduced into living cells. In a process known as gene cloning, the host cell's biochemical processes are used to make many copies of the inserted gene and the protein it codes for.
Explanation:
An example of homologous structures in vertebrates is
where the wings of bats, front flippers of whales, and forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.
The statement can be categorized as "False".
The food chain means that
all the living things get the food and energy or nutrition pass from one to
another. As you go up the food chain the abundance which the statement says
stays equal actually reduces and diminishes because of loss of energy through
normal procedures, for example, respiration etc.

<span>First - carhydrates are composed by Carbon, Hydrogen and Oxygen. Carbohydrates often suffer reactions of reduction, oxdation, amination, esterification, which gives every structur a specific property such as solubility. Now, fats are composed by several fatty acids and form mono, digli and triglicerids. This last ones are formed by Carbon, Hydrogen and Oxygen with a (-COOH) structure at the extremity. Protein, formed by linear aminoacids chains. Irs structure is determined by the aminoacids sequence. Now, steroids are derivated from the sterane, composed by Cabron and Hydrogen forming 4 merged rings, 3 hexagonals and 1 pentagonal.</span>
