Answer: a. skeletons of coral animals

A coral reef is a deep underwater ecosystem exhibiting walls or reefs build by corals. These reefs are formed by the colonies of organisms called as polyps, which are held together by calcium carbonate. The coral reefs are build in order to form stony corals, because of clustering of the polyps. The hard skeletonized structure provide protection to the polyps. These also provide shelter to small marine organisms like fishes.

Kipish [7]

Answer:

<u>State</u> anxiety is the actual experience of apprehension and uncontrolled arousal and <u>trait</u> anxiety is a personality characteristic, which represents a latent disposition to perceive situations as threatening.

Explanation:

<u>State anxiety:</u> It is basically a "right now" feeling which changes from moment to moment, manifesting itself as an interruption of an individual's emotion state, leading to a sudden superversion of emotional equilibrium, caused by external factors of current state. e.g An atheletes emotional state at any given time that is variable from situation to situation.

<u>Trait anxiety:</u> It is a personality disposition which is stable over time. e.g An atheletes disposition to interpreting a situation as threatning and responding with an increase in state anxiety.

Answer:

Explanation:

The energy carried by electromagnetic waves is sometimes referred to as radiant energy. Electromagnetic waves do not require a medium for propagation hence they can travel through vacuum and are known to transmit enormous amount of energy.

Electromagnetic waves transmit energy away from the source of the wave. Hence the answer chosen in the answer section above.

Like with living primates, we are able to definitively distinguish catarrhines from platyrrhines in the fossil record by what fe

Kazeer [188]

Answer:

The structure of their noses.

Explanation:

Catarrhines are distinguished from platyrrhines by several traits but the main distinctive feature between them, is the structure of their noses. This forms the basis of their names.

Platyrrhines are characterized by laterally-placed, rounded nostrils or flat-nosed while catarrhines have narrow, downward-facing nostrils or hooked-nosed.

Another distinguishing feature include their dental formulation which is 2.1.2.3 in catarrhines and 2.1.3.3 in platyrrhines.

The skull structure of catarrhines have frontal bone which make contact with the sphenoid bone unlike the platyrrhines.

Generally, catarrhines are much bigger in size than platyrrhines.

In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide fro

neonofarm [45]

The correct option is (C) Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.

In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide from the tissues to the lungs where, Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.

<h3>How does hemoglobin contribute to the movement of carbon dioxide from the tissues to the lungs?</h3>

The transport of carbon dioxide in the blood is influenced by a number of factors. First, blood contains more carbon dioxide soluble molecules than oxygen. The plasma contains 5–7% of the total dissolved carbon dioxide.
Second, carbon dioxide can enter red blood cells and bind to hemoglobin or it can bind to plasma proteins. In this form, 10% of the carbon dioxide gets transported.
A substance known as carbaminohemoglobin is created when carbon dioxide binds to hemoglobin. Hemoglobin and carbon dioxide can bind to one other again.
As a result, when it gets to the lungs, the carbon dioxide can separate from the hemoglobin without restriction and leave the body.
Third, the bicarbonate buffer system is responsible for transporting 85% of the carbon dioxide molecules.

I understand that the question you are looking for is "In addition to transporting oxygen from the lungs to the tissues, hemoglobin is also involved in transporting carbon dioxide from the tissues to the lungs. How is this accomplished?

A. Carbon dioxide competes for the oxygen-binding site on the heme.

B. Carbon dioxide competes for the 2,3-BPG-binding site.

C. Carbon dioxide reacts with an amino group to stabilize the deoxyhemoglobin state.

D. Carbon dioxide binds to the carboxyl terminus of hemoglobin."
