Which of the following correctly describes how nerve impulses move throughout the body?

1 answer:

7 0

The correct options are as follows:
1. ELECTRICAL TRANSMISSION THROUGH NEURONS AND CHEMICAL TRANSMISSION BETWEEN NEURONS [D].
Neurons, which are the nerve cells that carry nerve impulses are made up of cell body and dendrites. Electrical events propagate signals within a neuron and chemical processes transmit the signals from one neuron to the other.
2. SENSORY NEURON - BRAIN - SPINAL CORD - MOTOR NEURONS [B].
Waking up from sleep involves sensory neurons. Hearing of a strange sound is made possible by the activity of the brain. The man become alarm as a result of the message to the body from the brain via the spinal cord and running involves motor neurons.
3. MOTOR NEURONS AND SENSORY NEURONS [A].
The peripheral nervous system is one of the two components of the nervous system and is made up of the nerves and the ganglia outside the brain and the spinal cord. The neurons of the peripheral nervous system is made up of sensory and motor neurons. The sensory neurons bring signals to the central nervous system while the motor neurons carry signals out of the central nervous system.

Amylase is an enzyme that breaks down starch. why can’t the same enzyme break down cellulose?

rusak2 [61]

Enzymes are (usually) specific to the substrates they bind to. Thus, each enzyme has one and only one substrate structure they can metabolize, so even substrates with similar structures cannot be broken down by an enzyme specific to one of them.

valkas [14]

Answer:

Eukaryotic genetic variation occurs with vertical gene transfer while prokaryotic genetic variation occurs with horizontal gene transfer.

Explanation:

Genetic variation is when the genetic content of the offsprings are different from that of the parents. It is a phenomenon achieved in different ways by different organisms. Eukaryotic organisms undergo sexual and asexual reproduction in which they transfer genetic material (DNA) to their offsprings. This process of transfer of DNA from parents to their offsprings is called VERTICAL GENE TRANSFER. In sexually reproducing organisms, meiosis is undergone where CROSSING-OVER is the process that increases the chances of genetic diversity.

However, in prokaryotic cells that use other methods like transformation, transduction and conjugation to increase genetic diversity among their species since asexual reproduction does not produce genetically different offsprings. Prokaryotes like bacteria transfer or receive genetic material (DNA) from other bacteria species that are not their offsprings. This process is called HORIZONTAL GENE TRANSFER.
