Rank from the first to the last steps to describe the correct order of follicular development.
lisov135 [29]

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.

Most biological enzymes become denatured when they are heated and lose their ability to catalyze reactions. This process (origin
Setler [38]

Answer:

The denatured enzyme is more ordered.

Explanation:

Remember gibbs free energy equation, ∆G= ∆H - T∆S

Now since we aredealing with how ordered the original or denatured enzyme is, we are looking at their entropy.

When change in entropy us positive, then the original enzyme is more ordered but when it is negative, then the denatured enzyme is more ordered.

Making ∆S the subject formula from the equation,

∆S =∆G-∆H/T

Therefore protein denaturization is both endothermic and spontaneous. Temperature will always be positive.

∆S= (-) - (+)/(+)

∆S= -

Therefore the change in entropy is negative, the enzyme is more ordered and the denatured enzyme is more ordered than the original.

Which statement best explains the impact of favorable oceanic conditions on the Geosphere?
GREYUIT [131]

Answer:

The best answer is "Ocean waves add more sand to beaches"

Explanation:

based on statement above, the oceanic conditions are changes in ocean parameters (temperature and movement) and substances which contain in oceans (salinity, nutrient availability, oxygen and carbon dioxide level, etc).

Geosphere is a part of the earth that included the earth's interior, landform, rocks, and mineral. There are lithosphere, atmosphere, hydrosphere, biosphere and, anthroposphere.

on the answer choice, the ocean wave is the example of the oceanic condition which has changed in movement. and the beach is an example of the lithosphere.
