Answer:
The light reactions occur when light is absorbed by the chlorophyll in plants. ... Water splits, producing oxygen gas which is released through the stomata on plant leaves. The dark reactions occur in the stroma of the chloroplasts when carbon dioxide is converted to sugar using energy derived from ATP and NADPH.
Explanation:
The first cell that was viewed by the light microscope was the oak bark.
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."
Answer:
Option (A)
Explanation:
The Precambrian represents the time period, right from the beginning of the earth to about 540 million years back. It is divided into 3 parts, namely the Hadean, the Archean and the Proterozoic. Throughout this geological time, vast changes have taken place on earth. The first life forms of about 3.8 billion years old, that existed on earth were the simple unicellular organisms, whose traces were only found at some particular places. These organisms were very small and are comprised of soft bodies, so they were affected by the earth's dynamic processes. The organisms in order to get fossilized must contain hard parts. Due to the presence of soft bodies, the organisms were not fossilized and so it took a long time to demarcate that the late Precambrian organisms were animal-like life.
hence, the correct answer is option (A).
Answer:
<h3>The afterglow is an intense red glow of the atmosphere long after sunset (or long before sunrise), when most twilight colors should have disappeared. The afterglow is caused by dust in the high stratosphere, which catches the hues of the twilight arch below the horizon.</h3>
