Ahat [919]

Answer:d) contracting her pupils and increasing secretion of stress hormones.

Explanation:

Peripheral nervous system consists of 3 major neuronal levels: vegetative (reticular formation and brain stem), limbic system and neocortical level. The RAS is the link between the brain and the spinal cord.

Brain stem consists of pons, medulla oblongata and mesencephalon. Brain stem is responsible for involuntary functions such as heart beat, respiration and vasomotor activity. Limbic system represents the emotional control center. It consists of thalamus, hypothalamus and pituitary gland and maintains homeostasis. Neocortical part processes sensory information and regulates emotional responses.

Autonomic nervous system (ANS) regulates visceral activities and organs (circulation, digestion, respiration and temperature). ANS has two divisions: sympathetic and parasympathetic nervous system.Parasympathetic nervous system regulates homeostasis via the release of acetylcholine (Ach). Parasympathetic nervous system is responsible for energy conservation and relaxation.

There are three stages in the stress response: immediate effects of stress, intermediate effects of stress and prolonged effects of stress.

<h2>Mitosis Process</h2>

Explanation:

Plant cells and animal cells undergo the same cellular processes during mitosis.

The centrioles absent in the plant.
Animals cells have centrioles, to what delivers the shaft strands is one of the differences among plant and creature mitosis.
The periods of mitosis and goes on in each stage is the equivalent aside from when it comes to how cytokinesis is practiced.
<em>Plant cells separate the cytoplasm between the two new cores by framing a cell plate (new cell wall)between the cores.</em>
Animals cells achieve this by shaping a cleavage wrinkle which is a squeezing in at the center of the<em> </em><em>cell until two new cells have been framed with cytoplasm and organelles for each new nuclei.</em>

Type of nitrogenous base with a double ring found in DNA and RNA:

svet-max [94.6K]

Answer:

The correct answer will be option-B (purine).

Explanation:

Nucleic acid structure is made up of monomer unit called nucleotide. Each nucleotide is composed of a five-carbon sugar, a phosphate group and five types of nitrogenous bases.

The nitrogenous bases are categorized in two forms the purines (adenine and guanine ) and the pyrimidines (cytosine, thymine and uracil). The "purines" contain double rings in their structure due to which they appear larger in size than pyrimidines which are made up of single rings.

Thus, Option-B is the correct answer.
