Question 2 of 9
Jlenok [28]

Answer:

The correct answer is option D.  Light and some other factors are necessary for chlorophyll production

Explanation:

By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.

Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.

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."

Question 23 (6 points)
Stels [109]

Answer: 1. Sea urchins and sea otters

2. They are prey for carnivores.

3. Sea otters, star fish

Explanation:

Sea urchins and sea otters are carnivores as they eat on the flesh of starfish and sea urchins respectively.

Starfish feed on the kelp forests which are the producers in the food chain and the starfish is the primary consumer and prey for sea urchins.  So, starfish and kelp forests are the prey in the marine ecosystem.

Keystone species is the one which controls the population of other inferior species in an ecosystem. Here, sea otters consume sea urchins so the population of sea urchins remained in control Starfish controls the population of kelp forest.
