Answer:

B. Body temperature is controlled by an internal feedback mechanism.

Explanation:

The monitoring of body homeostasis is mainly performed by the feedback mechanisms that keep homeostasis within a balance of antagonistic actions, ie, contrary. Body temperature, for example, is controlled by the feedback mechanism.

When a certain change occurs in the human body, the feedback mechanism can react in two ways: positive feedback and negative feedback.

Negative feedback acts to reverse the change that has occurred. Let's look at an example: When body temperature decreases due to cold, skin receptors send messages to the brain informing about the decrease in temperature. The brain, in turn, sends a response to the muscles to contract (tremor) and thereby generate heat. When body temperature returns to normal, the brain will transmit information to the muscles to stop the contractions. Therefore, on cold days, our body “shakes” and consequently generates heat.

Free_Kalibri [48]

The question is incomplete. The complete question is as follows:

Select the correct answer from each drop-down menu.

Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response. Two neurons communicate with each other through the ( axon , dendrite, synapse) . The ( cerebrospinal cord, glial cell, neurotransmitter) is released at the site to initiate action potential and carry the signal through the body.

Answer:

synapse

neurotransmitter

Explanation:

Neurons are the basic units for the transmission of signals to the central nervous system. The two neurons are connected through the syanpse. Synapse is the space or junction between two nerve cells, or neurons.

The neuron receives signals through dendrites and two neurons  communicate with each other through a chemical called neurotransmitter, which is released at the end of a nerve fibre and carry the signal through the body.

Hence, the correct answers are synapse and neurotransmitter.

solniwko [45]

1) Mice not radio waved.

2) Radio

3) Strength of mice

4) Maybe inconclusive.

5) Improves strength

Explanation:

  1. Control Group - Mice not radio waved.
  2. Independent Variable - radio.
  3. Dependent Variable - Strength of mice.
  4. What should Bart's conclusion be? Maybe inconclusive.
  5. How could Bart's experiment be improved? Improves strength

Experimental setup

setup that is testing a hypothesis using a variable. In most cases only one variable should be tested at a time.

Control Setup

setup that is identical to the experimental setup, only it does not contain a variable.

Independent Variable

The one factor that is change by the person doing the experiment

Dependent Variable

The factor which is measured in the experiment

Constant

all the factor that stay the same in an experiment.

"In proteins, structural segments called ____ provide flexibility that allow parts of the protein to bend, fold, or move."
Rainbow [258]

Answer:

The correct answer is "random coils".

Explanation:

Random coil is a type of polypeptide secondary structure comprised of conformation that do not follow an established conformation but rather are oriented randomly. These random coils conformations provides flexibility to proteins, since the lack of a particular structure (such as alpha helices or beta sheets), allows the protein to bend, fold or move.
