The male structure, called the testes
Stages of follicular development include in ovulation:
Primordial follicle
Primary follicle
Secondary follicle
Vesicular follicle
Ruptured follicle
Corpus luteum
Corpus albicans
The follicular phase (i.e., follicle formation) starts on day one of a typical 28-day cycle, which is marked by the beginning of menstruation, and lasts until today (i.e., ovulation). At this point, the antral follicle is FSH-dependent and starts to compete for the hormone with other growing follicles.
- Before an ovarian follicle releases its ovum, it goes through a number of unique phases. A limited number of primordial follicles emerge in the fetal ovary throughout the course of the first five months of development. The oocytes in these follicles are enclosed in a single layer of squamous follicular cells.
- There are only a certain number of primordial follicles that are stimulated to form at the beginning of each menstrual cycle. The early primary follicle, which has a core oocyte surrounded by a single layer of cuboidal-shaped follicular cells, is the earliest evident histological stage.
- When a follicular antrum is seen within the granulosa layer, secondary follicles can be distinguished from primary follicles. Hyaluronan and proteoglycan-rich fluid is found in the antrum.

Substrate -level phosphorylation accounts for approximately 100% of the ATP formed by the reactions of glycolysis.
The direct transfer of a phosphate group to ADP to form ATP is known as substrate-level phosphorylation. It accounts for all of the ATP produced by glycolysis reactions. The first substrate-level phosphorylation occurs when 1,3-diphosphoglyceraldehyde is converted to 1,3 diphosphoglyceric acid and 2 NADH2, resulting in the formation of 6 ATP. Substrate-level phosphorylation converts the 1, 3-diphosphoglyceric acid to 3 phosphoglyceric acid, which produces 2 ATP. The second substrate-level phosphorylation takes place when phosphoenolpyruvic acid is converted to pyruvic acid, which results in the formation of two ATP molecules.

The correct answer is option a, that is, It is sometimes sprayed too far from the crops.
The use of pesticides on crops may exhibit a significant threat to the environment, mainly in and nearby to water sources with sensitive ecosystems, sources area, public drinking water, residential areas, and recreational waters.
Aircraft spray of pesticides takes place from a greater altitude than the ground-based equipment and on a major scale, both of these elements may enhance the threat of spray drift.
