How do ice cores, tree rings & index fossils provide valuable information about the past?

1 answer:

4 0

Tree rings are annual growth rings and their thickness indicates how growing conditions were for that year. Index fossils in their type and frequency are indicative of the environment that those organisms grew in and how prolific life was then in that environment. Ice cores drilled through glaciers and ice sheets like in Antarctica tell us about such things as the concentration of greenhouse gases like carbon dioxide (as bubbles in the ice layers) and also about climatic conditions in glacial and interglacial periods.

Is it better to learn about animals through a book, or actually going to see them in real life?

Norma-Jean [14]

I think in real life because you get to see how they act and i have been on three trips i know that this is not related but I've been to Egypt and Italy and china and i am in 7th grade so ya. I think seeing animals and things in real life is the best thing to do overall.

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."
