Hey There Jinny,

What is the most important difference between vertebrates and invertebrates

The primary difference between vertebrates and invertebrates is the presence of a backbone or spinal column, which vertebrates have and invertebrates do not. Examples of vertebrates are humans, dogs, cats and birds. Examples of invertebrates are flatworms, mollusks, sea urchins and insects.

faltersainse [42]

Answer:

Medulla oblongata is responsible for autonomic regulation system.

Explanation:

Autonomic regulation is a controlling system that regulates different function of body such as heart rate,digestion,blood pressure,urination,respiratory rate,papillary response etc.

Hypothalamus is the main center of controlling this functions.

Autonomic dysfunction occur when autonomous nervous system damages,and the effect may be mild to life threatening.

Autonomic activity may leads to certain kind of side effects like-

Dizziness,fainting
exercise intolerance.
sweating abnormalities.
Diarrhea,constipation,difficulty in swallowing.
Urinary problems,incomplete emptying of the bladder.
Vision problems,blurry vision,vaginal dryness etc.

Answer:

According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.

Explanation:

Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.

In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.

Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.

In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.

The other options are not correct because:

Cell growth occurs in G1 phase.
Cell preparation occurs in interphase.
DNA replication occurs in S phase.
Mitosis is represented in yellow, and involves 4 phases.
