Which statement about sexual reproduction in flowering plants is true
asambeis [7]

Answer:

D) Asexual reproduction produces offspring that are genetically identical to the parent.

Explanation:

I am honestly not quite sure of this answer, but I was trying to read up on the topic and this is the answer I'm most confident in. It would make sense that the offspring are genetically identical to the parent because they would have no where else to get their genes/mix to form new ones. I really hope this helps!

Which person’s function in a school is similar to the central nervous system’s role in a human body?
Alekssandra [29.7K]

Explanation:

options...

-a cafeteria worker

-a student

-a principal

-a bus driver

<u>correct: -a principal </u>

Further explanation:

The model places the principal as the brain or control center, where it regulates all activities related to homeostasis, just like a school.Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. They are interdependent, and work together like members of a school, as tissue.

The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.

The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system (ANS) which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.

What statement does NOT pertain to the cephalic phase of gastric secretion? (It controls the rate at which chyme enters the smal
egoroff_w [7]

Answer:

It controls the rate at which chyme enters the small intestine

Explanation:

Cephalic phase is one of the phase of gastric secretion (other two are gastric phase and intestinal phase) that begins even before food enters the oral cavity. Thinking of food stimulates the release of gastric juice via  parasympathetic nervous system). Food that enters the stomach also stimulates the secretion of gastric juice by parietal cells. Partially digested food directly activates  G cells (Enteroendocrine cells) to secrete gastrin which also stimulates the release of gastric juice.
