Answer:

The correct answers are "bones in mammals" and "calcium-rich plates in echinoderms"

Explanation:

Endoskeletons are defined as internal structures of animals that give support to the body and are generally comprised of a mineralized tissue. Two examples of endoskeleton are the bones in mammals and the calcium-rich plates in echinoderms. The bones in mammals and other vertebrates are internal structures made of mineralized collagen, while the calcium-rich plates in echinoderms are internal structures that are interconnected and covered for an epidermis organ.

barxatty [35]

Answer:

The atoms of each element have a characteristic number of electrons arranged in electron shells. The number of valence electrons determines what types of bonds or ions the atoms may form, so the chemical reactivity of an atom arises from its electron distribution. The properties of compounds emerge from the arrangement of their constituent atoms and of the bonds between them.

Thus, a wide variety of molecules with very different chemical properties can be made from the same basic atoms. Each molecule has a distinctive size, shape, and charge distribution, which determine its highly specific ability to interact with other molecules.

Compounds in chemical wastes may contaminate the environment if their atoms are combined in new arrangements that harm living organisms.

Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate,
Nuetrik [128]
Phosphofructokinase is an allosteric enzyme that catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate. This a an early reaction in the glycolysis pathway that is a regulatory step in the pathway. An increase int he amount of ATP in the cell might cause decrease in the amount of phosphofructokinase enzyme by a process called feedback inhibition. Glycolysis process is regulated at various steps in which conversion of fructose 6-phosphate to fructose 1,6-bisphosphate is one of the regulatory step.

Answer: In the presence of oxygen, an increase in the amount of ATP in a cell would be expected to INHIBIT THE PHOSPHOFRUCTOKINASE ENZYME AND SLOWS THE RATE OF GLYCOLYSIS.
