Answers

Answer 1

Answer:

The best definition for a macromolecules is the most abundant elements found in living cells. The correct option is d.

What are macromolecules?

A macromolecule, such as a protein or nucleicacid, is a very large molecule that is important in biophysical processes.

It is made up of thousands of atoms that are covalentlybonded. Many macromolecules are polymers composed of smaller molecules known as monomers.

Macromolecules are essentially polymers, which are long chains of molecular subunits known as monomers.

Long polymers are found in carbohydrates, proteins, and nucleic acids. They are classified as macromolecules due to their polymeric nature and large size.

Macromolecules are made up of monomers, which are single units joined together by covalent bonds to form larger polymers. The most abundant elements found in living cells are the best definition for macromolecules.

Thus, the correct option is d.

Answer 2

Answer:

Answer:

There are no answers to choose from.

Explanation:

However, the prefix macro- means big, so the word macromolecule means large molecule. Macromolecules are also known as the molecules of life, they all contain carbon. The four macromolecules are carbohydrates, proteins, lipids, and nucleic acid. Carbohydrates are used as a quick energy source, they can be broken up into monosaccharides, dsaccharides, and polysaccharides. Proteins are used as catalyst to help speed up chemical reactions. Lipids are also known as fats, they can either be saturated or unsaturated. Nucleic acids contain information.

Examples of each:

Carbohydrate- Gluten

Protein- Lactase

Lipid- butter, or oil

Nucleic Acid- DNA or RNA

Digestion and breathing are _____. controlled by ganglia and plexus reflexive actions controlled by the spinal cord voluntary actions controlled by the central nervous sytem

Answers

Answer:

The correct answer is - reflexive actions controlled by the spinal cord.

Explanation:

Digestion and breathing are examples of involuntary action which is controlled by the autonomic nervous system of the CNS. however, the part of the nervous system that controls is the spinal cord and hind brain by the spinal reflex actions.

These are the action they do not require any thought and work without any thought that leaves the brain for other actions and coordinations. specific but the same stimuli causes the response in the same way.

Based on each person's statements, identify which of the following you AGREE with, and then explain your reasoning. Courtney: “It is obvious that everything that eats plants would die but all the other organisms on the island would be okay.” Jose: “Courtney I think the organisms that eat plants would just learn to eat other things. So initially they might decline in numbers but eventually, their numbers would increase back to their current amount.”Raquan: “I have to disagree with both of you. I think that all of the organisms on the island would die, because at some point even the mammals who don’t eat plants directly would ultimately discover that what they usually ate has already died.” Mike: “I kind of agree with Courtney, except I don’t think that all of the things that eat plants will die. I think the things that eat both plants and animals would live and only those that can’t or won’t eat animals will die.” Keisha: “Mike is right. I would add that since there are fewer things for the larger mammals to eat that we would ultimately see fewer of them on the island.” Alex: “I argue that organisms that eat plants would learn to swim so they can eat the seaweed and algae in the water.”Plzz explain your reasoning!!
