The sunflower is intolerant to shade exposure and needs full sun exposure. It has adapted to this necessity by having a heliotropic head which rotates to follow the sun, hence the name sunflower
In common terms, the ventilation cycle is known as “Breathing” and its cycle is in and out movement of air from the lungs. Inspiration is defined as airflow inside the lung and expiration is when the air leaves the lungs with a small pause between inspiration and expiration known as the rest period.
For the body to get oxygen and expel carbon dioxide, inspiration (breathing in) and expiration (breathing out) are essential actions. Expiration is often passive unless it is pushed, whereas inspiration involves the active contraction of muscles, such as the diaphragm.

Answer:
Treg cells accumulate after ischemic stroke (175). Astrocytes increase the level of IL-33 and CCL1 in response to stroke. IL-33 is thought to promote the proliferation of Treg cells because their numbers in the CNS after stroke is decreased in IL-33-deficient mice (175).
Answer:
Growth of cell and replication of DNA
Explanation:

- It is a long, non-dividing, growing phase of the cell cycle, where the cell prepares itself for division.
- It represents the most active stage of the cell cycle where both cell growth and DNA replication occur in an orderly manner.
- It is the period of intense growth and synthesis in which a cell stocks all the biomolecules required during cell division.
- It is called the resting phase because there is no apparent activity related to cell division rather, it deals with the changes that occur in a cell and the nucleus, before it enters into cell division.
