Biology
1 answer:
iragen [17]3 years ago
4 0

The distribution of related animals and plants across the world shows that those organisms have common ancestor.

There is a term in biology- the most recent common ancestor (MRCA) and it is the most recent individual from which all the organisms are directly descended. It is hard for scientist to identify the exact MRCA, but it is estimated the time at which the MRCA lived (3.5 to 3.8 billion years ago). It is called Last Universal Common Ancestor (LUCA).

Endoplasmic Reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.

Golgi Apparatus: A cell structure that helps make and package materials to be transported out of the cell or for storage inside the cell.

Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell, such as large food particles or old parts of the cell. May be found only in animal cells.

Vacuole: Saclike storage structure in the cell. can store water, nutrients, and even toxic substances.

Mitochondrion: An organelle containing enzymes responsible for producing energy. (Metabolism/respiration)

Chloroplast: An organelle found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis).

Is the vagus nerve the heart rate centre of the brain?
koban [17]

Answer:

The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brain stem to the body. It allows the brain to monitor and receive information about several of the body’s different functions.

Explanation:

The vagus nerve is the longest and most complex of the 12 pairs of cranial nerves that emanate from the brain. It transmits information to or from the surface of the brain to tissues and organs elsewhere in the body.

There are multiple nervous system functions provided by the vagus nerve and its related parts. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts

The vagus nerve has a number of different functions. The four key functions of the vagus nerve are:

-Sensory: From the throat, heart, lungs, and abdomen.

-Special sensory: Provides taste sensation behind the tongue.

-Motor: Provides movement functions for the muscles in the neck responsible for swallowing and speech.

-Parasympathetic: Responsible for the digestive tract, respiration, and heart rate functioning.
