Which sentence best describes the relationship between genes and chromosomes?

Biology
1 answer:
Maurinko [17]3 years ago
6 0

Answer:

A. Genes are found within chromosomes.

Explanation:

A chromosome is a single linear, coiled DNA molecule that contains part or even all the genetic material of an individual. On the other hand, genes are chromosomal segments that contain the instructions required to encode a specific protein, which is stored in the form of a sequence of nucleotides. In consequence, a chromosome may have many genes. In biology, a gene is considered to be the basic physical and functional unit of heredity.

Hyperpolarization means that the ________. Group of answer choices membrane potential becomes more negative than the resting pot
gladu [14]

Answer:

Hyperpolarization means that the membrane potential becomes more negative than the resting potential.

Explanation:

The voltage across the membrane of a neuron that is at rest and not sending out signals is called the resting membrane potential, or just the resting potential. The concentration gradients of ions across the membrane and the amount of each type of ion that can pass through the membrane determine the resting potential. When a neuron is at rest, there are different levels of sodium and potassium on both sides of the cell membrane. Ions move down their gradients through channels. This creates a difference in charge, which gives rise to the resting potential.

When the membrane potential at a particular location on the neuron's membrane gets more negative, this phenomenon is known as hyperpolarization. Depolarization, on the other hand, occurs when the membrane potential becomes less negative (more positive). Both depolarization and hyperpolarization can take place as a result of the opening and closing of ion channels in the membrane, which changes the rate at which certain types of ions can enter or leave the cell.
