One reason biodiversity is such an important aspect of sustainability is that it provides vital ecosystem services through the interactions among species and keeps any population from growing too large (option A).
<h3>What is biodiversity?</h3>
Biodiversity refers to the number and variety of species of plant and animal life within a region.
Sustainability is the means of configuring civilization and human activity so that society, its members and its economies are able to meet their needs and express their greatest potential in the present without compromising the ability of future generations to do the same.
Biodiversity helps to ensure sustainability because it provides vital ecosystem services through the interactions among species and keeps any population from growing too large.

A chromosome contains one long DNA strand.
B.
<span>Answer
1. electrical signal travels toward the heart
2. signal by the nodes in the atrium</span>
3. the atria contract<span>
</span>4. signal received by the atrioventricular node
5. signal transferred to the ventricles
6. the ventricles contract
Heart has a pacemaker that will continually send a signal. The primary site of the pacemaker is at the sinoatrial node, on the top right atrium. This node will send a signal to atria (which will cause it to contract) and to the atrioventricular node.
Atrioventricular node located between atrium and ventricle. It will send the signal to the ventricle(by the bundle of his) and cause it to contract.
