includes all descendants from a single common ancestor. does not share any common ancestry but represents convergent evolution.
Tju [1.3M]

Answer:

Phylogenetic relationships

1. includes all descendants from a single common ancestor >>> monophyletic group

2. does not share any common ancestry but represents convergent evolution >>> polyphyletic group

3. includes some but not all descendants from a single common ancestor >>> paraphyletic group

Explanation:

A monophyletic taxon is a collection of organisms that have the same most recent common ancestor, thereby including an ancestor and all its descendants. Examples of monophyletic groups are angiosperms, mammals, insects, etc. A paraphyletic group is composed of some (but not all) the descendants of the most recent common ancestor. An example of a paraphyletic group includes fish and lizards. Finally, a polyphyletic taxon is composed of a group of organisms that do not contain the common ancestor of all the members of the group. An example of a polyphyletic group is composed of birds and mammals, (which constitutes a group of warm-blooded animals).

Fatty acids that are necessary for proper health but cannot be synthesized by the body are called ________ fatty acids.
PtichkaEL [24]

Fatty acids that are necessary for proper health but cannot be synthesized by the body are called gluconeogenesis fatty acids.

<h3>What is gluconeogenesis?</h3>
  • The process of producing glucose (sugar) from lipid (fat) or protein breakdown products, as well as from its own breakdown products.
  • Gluconeogenesis primarily takes place in liver or kidney cells.
  • The process of producing glucose in the body from non-carbohydrate precursors is known as gluconeogenesis.
  • New glucose is produced by biosynthesis, not through the ingestion of carbohydrates.
  • Lactate, pyruvate, glycerol (fat), and certain amino acids can all be converted into glucose (protein).
  • Both the kidneys and the liver engage in glucose synthesis.
  • Between meals, gluconeogenesis meets the need for plasma glucose.
  • The hormones that cause diabetes encourage the production of glucose (glucagon, growth hormone, epinephrine, and cortisol).
  • Glycerol, lactate, propionate, and a few amino acids are examples of gluconeogenic substrates.
