Answer:
<u>Origin:</u> In biology, origin can be described as the location where the muscle joins a stationary bone and as a result, no movement occurs.
<u>Insertion: </u>In anatomy, insertion can be described as the point of attachment which allows movement of a bone to occur. It moves when the muscles contract.
<u>Tendon:</u> In biology, the tendon can be described as a type of connective tissue which attaches a bone to a muscle.
The answer is <span>A. presence of cell membranes.
A classification of living things can be based on many different characteristics but a presence of cell membranes is not one of them. <u>ALL living things have cell membranes.</u> So, <u>there could be no classification</u> of organisms with cell membranes and organisms without cell membranes.
On the other hands, based on mode of nutrition, organisms can be classified of autotrophs and heterotrophs. Based on presence of nucleus, organisms can be prokaryotes (without a nucleus) and eukaryotes (with the nucleus). Number of cells is base for classification of living things on unicellular and multicellular.</span>
Metaphase. Easy way to remember is this is the chromatids align on the metaphase plate
Answer:
In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.
