A metabolic pathway is a chain of sequenced reaction whereby the products of the preceding reaction act ad the substrate for the proceeding reaction, until a final product is achieved.
Metabolic pathways are not necessarily anabolic. Some are catabolic.
Explanation:
Examples of catabolic pathways are the Krebs and Glycolysis cycles that are used by cells to generate ATPs. They break down the bonds of glucose molecules to harness the chemical energy in the bonds.
Examples of anabolic metabolic pathways is the Calvin cycle in plants that uses up ATP energy to reduce carbon dioxide into carbohydrates, storing sunlight energy into chemical energy in the bonds of the glucose molecules.
Virtually all organisms that share the same ancestor have the same metabolic.pathways in cells hence revealing an evolutionary relationship.

Answer:
Closest to the equator
Explanation:
The tropical zone is in the middle region of the Earth, which is the closest to the equator. Mark as brainliest please:) I hope this helps.
It implies that There are 46 chromosomes (dsDNA (double-stranded) molecules) are present in each somatic cell.
Homo sapiens has 46 chromosomes divided into 23 pairs: 22 pairs of autosomes and 1 pair of gonosomes or sex chromosomes, called X and Y. Male individuals have X and Y (XY) chromosomes. Female individuals have 2 X (XX) chromosomes.
Aneuploidy is an abnormal change in the number of chromosomes in a cell or organism (for example 45 or 47 chromosomes).
In addition to the chromosomes in the nucleus, human cells have DNA in the mitochondria (circular DNA).
Answer:
an endoskeleton is a skeleton on the inside of a living creature. look at endo like enter, its on the inside! an exoskeleton is on the outside of a living creature. think of exo as exit, its on the outside! animals with endoskeletons are like dogs, cats, fish, and raccoons. animals with exoskeletons are like spiders, ants, crabs, and snails.
