vova2212 [387]

Cellular communication is the function of the plasma membrane that allows it to respond to certain stimuli from outside the cell and hormones to bind to receptors.

<h3>What is plasma membrane?</h3>

It is a double layer of lipids that covers and delimits the cells, serving as a border between the inside and the outside of the cell, and also allowing a physicochemical balance.

<h3>Characteristics of plasma membrane</h3>

Enables the development of compartments; allows or rejects the entry and/or exit of particles; acts as a mechanical defense; and reacts to external signals and stimuli.

It reacts and transmits information inside the cell, starting certain biochemical processes: cell division, cell movement or the segregation of biochemical substances.

Therefore, we can conclude that the main characteristic of the plasma membrane, that is, its ability to allow or reject the entry of certain molecules into the cell.

What statement does NOT pertain to the cephalic phase of gastric secretion? (It controls the rate at which chyme enters the smal
egoroff_w [7]

Answer:

It controls the rate at which chyme enters the small intestine

Explanation:

Cephalic phase is one of the phase of gastric secretion (other two are gastric phase and intestinal phase) that begins even before food enters the oral cavity. Thinking of food stimulates the release of gastric juice via  parasympathetic nervous system). Food that enters the stomach also stimulates the secretion of gastric juice by parietal cells. Partially digested food directly activates  G cells (Enteroendocrine cells) to secrete gastrin which also stimulates the release of gastric juice.

Which of the following is a function of vascular tissue?
STALIN [3.7K]

Answer: Provides support for the blade of the leaves.

Explanation:

Vascular tissues are conducting tissues formed from specialized cells . The two conducting vascular tissues in plants are xylem and phloem.

Xylem tissue transport water and nutrients from plant roots to all part of the plants. Phloem transport sugars. It also provide structural support for plants. Vascular tissues run through the veins of the leaves and provide support. Vascular tissues are found in vascular plants.

Which characteristic of the genetic code lowers the likelihood of mutation?
Rudik [331]
Degeneracy

Degeneracy simply means that most of the amino acids produced during protein synthesis from DNA is coded by more than one codon. A codon is a sequence of 3 <span>nucleotides that codes for a specific amino acid.

Because more than 1 codon can produce the same amino acid, the chances of having the synthesis of proteins affected by mutations (i.e. point mutations) is decreased. For example, if the codon with the nucleotide series GAA, which codes for the amino acid glutamate, becomes the codon GAG, the codon will still produce glutamate because the code is degenerate. </span>
