The correct answer among the choices provided is option A. Lung capillaries are responsible for exchanging carbon dioxide for oxygen from the air. Blood that comes from the heart gets oxygen from the alveoli. The carbon dioxide in the blood goes into the alveoli at the same time.
Production of sperms is referred as spermatogenesis and production of ovum or egg is called oogenesis. Spermatogenesis and oogenesis are similar in a way in humans as bth these processes produce large numbers of sperms and eggs. Spermatogenesis is a continuous process where large numbers of sperms are produced at once and uses less energy. Ovulation is a process where only one egg or ovum matures at a time requires more energy. Not all the egg cells mature in females.
<span>The three essential principles of test construction are listed below:
I. Standardization
II. Reliability
III. Validity
</span>Standardization- To standardize a test means that test is given to a large, representative sample of people, in order to establish the norms that future test takers are compared against (using a normal distribution)
Reliability - This principle requires that a test must produce reliable, consistent results when it is repeated. The reliability of a test can be verified using the test-retest method or the split-half method.
Validity - This refers to the ability of a test to measure what it was designed to measure.
The breaking down of
sugars is called glycolysis. The prefix glyco- means sugar, and the suffix
-lysis means breaking down. It's part of a three-step process in respiration,
the other two is The Krebs Cycle and Electron Transport Phosphorylation. In the
process of glycolysis, 2 ATP and 2 NADH are produced.
