Answer:
The <em>tetrad</em> occurs during the first phase of meiosis. It is the foursome of <em>chromatids</em> that forms when replicated homologous chromosomes align. It must be formed for crossing over to occur. It is broken apart when the homologous chromosomes separate in meiosis I.
Answer:
Mid ocean ridge
Explanation:
They are formed under water and there movement is generally up an out. I hope you get it right!
Answer:
The function of the proteins that are embedded in the cell membranes is to transport materials in and out of the cell. Proteins are large sized biomolecules that are also referred to as macromolecules at times. They are made up of large chains of amino acid molecules.

Answer:
<u><em>The correct option is D) Does the amount of radiation from the sun affect air temperature?</em></u>
Explanation:
The graph represents the effect of Sunlight or global radiation on the temperature of the air present in the atmosphere.
As we know, as the amount of radiation increases, the temperature of the Earth also increases. This phenomenon is perfectly illustrated in the graph mentioned in the question. Hence, D is the correct option.
Other options like option A are not correct because the graph does not illustrates the parts of the Earth which receive the most global radiation over a year.
Answer:
The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.
Explanation:
The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.
The process of <u>cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions</u> where, from a glucose molecule, energy is obtained in the form of ATP molecules.
Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:
<em>C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂</em>
This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.
For the other options it is important to mention that:
- <em><u>C₆H₁₂O₆</u></em><em> is the substrate from which cellular respiration takes place.
</em>
- <em><u>ATP </u></em><em>is the final product of cellular respiration, translated into energy to be used by the cell.</em>
