Sheryl is observing ovarian slides taken from a female ape. All the cells show crossover chromosomes. What is this stage?
Kobotan [32]
<span>The stage at which all the cells show crossover chromosomes is meiotic prophase I. The crossover is the exchange of genetic material between homologous chromosomes. Homologous chromosomes are present in the meiosis I. Regarding the phase of meiosis I, it is expected that the crossover takes place in meiotic prophase I since homologous chromosomes pair up in the prophase.</span>

Which of the following statement(s) is/are true regarding the adrenal glands' relationship with the autonomic nervous system?
Studentka2010 [4]

Answer:

The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:

a. The adrenal cortex is an extension of the parasympathetic nervous system.

c. The adrenal glands are strictly nerve tissue.

d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.

e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.

Explanation:

The  levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord.  Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs.  This alert serves as a warning signal and defense system.  The purpose is to maintain homeostasis.

The primary producers in an ocean grazing food web are usually ________.
Butoxors [25]

Answer:

phytoplankton

Explanation:

Phytoplankton can be defined as a set of photosynthesizing microorganisms that live floating on the water surface. It is composed of microscopic algae and cyanobacteria, which can be unicellular, colonial or filamentous. These microorganisms are defined as the primary producers of an ocean grazing food network.

Because phytoplankton live in aquatic environments - both in limic (eg lakes) and marine environments - they have a number of adaptations that guarantee their survival in the water column.  Some of these microorganisms, for example, have flagella that aid locomotion; others, in turn, have gas vacuoles that aid in flotation, while some of them have mucilage, which surrounds the cells and ensures protection, flotation and locomotion.

Drag each tile to the correct box. Explain the process in which hormones secreted by the pancreas function with respect to incre
ValentinkaMS [17]

Answer:

1) intake of glucose molecules from the blood by specific transporters

2) high amount of glucose in the blood, sending signals toward the pancreas

3) binding of hormones with receptors on the liver

4) release of hormones from the receptors

5) synthesis of hormones by beta cells

Explanation:

During ingestion of the meal, insulin is produced in response to high blood glucose levels (concentration of glucose increases after digestion of food). Like other hormones, insulin performed its action through binding specific signals to specific receptors e.g, liver, muscle cells.  The high glucose level in the blood send signals through hormones to liver, fat, and muscle cell receptors. These receptors release specific hormones to beta cells of the pancreas. In response to the signals from receptors, beta cells synthesize insulin to minimize glucose levels in the bloodstream.
