Explain how the concentration gradient of oxygen and carbon dioxide are maintained in the amoeba

Pamela watches her cat Mr. Big swat his paw at the wall and calls out, "Crazy Big, what are you swatting at; nothing is there."

Advocard [28]

Answer:

a. Cats see low-frequency, low contrast objects better than humans.

Explanation:

Mr. Big is able to see something that Pamela does not see because cats have a wider field view of about 200 degrees while that of humans is about 180 degrees.

Cats eyes have 6-8 times more rod cells, which are more sensitive to low light, than that of humans. Their elliptical eye shape, large tapetum and cornea help to gather light for better vision at night.

signals from the _________ sense do not pass through the thalamus but go more directly to the limbic system

exis [7]

The signals from our sense of smell do not pass through the thalamus and instead go more directly to the limbic system.

The thalamus is a small structure located just above the brain stem with the function of relaying motor and sensory signals. The thalamus works in conjunction with the cerebral cortex, to whom it relays said signals, which explains its location in between the cerebral cortex and the midbrain. It is able to carry out these functions due to a network of nerves that connects it to its neighboring structures.

The limbic system is a group of neural structures that serve to:

Process and regulate emotions
Form and store memories
Control sexual urges
Participate in the process of learning

The signals from our sense of smell do not pass through the thalamus. They instead travel down their corresponding sensory nerve, the first cranial nerve known as the olfactory nerve, and go more directly to the limbic system.

Your belly releases ghrelin when it is empty to signal your mind that it is time to devour. Ghrelin is often called the starvation hormone, but it does extra than manage starvation. It also signals your pituitary gland to launch boom hormones, plays a position in insulin release, and protects your cardiovascular health.

What is the principal reason that appetite is turned off immediately after a person finishes an intense workout

1) The sense of smell and taste are suppressed for at least one hour.

2) Glucose and Fatty acid are abundant in the blood.
