<span>1) It is the chromosomes, however, that assort independently, not individual genes.
2) </span> <span>It tells you they're really far apart.
You see, there's this phenomenon called crossing over. Chunks of DNA get randomly swapped between homologous chromosomes. If two genes are close together they're usually swapped together and if they're far apart (say, on opposite ends) they're probably never going to be swapped together because half a chromosome doesn't normally cross over at once.

3) <span>Sexual reproduction, because it results in offspring that combine alleles from two different individuals. </span>
<span>(Crossover is fine and dandy and you should mention it, but you'd get a C if you didn't mention that two different individuals are contributing genetic material to the offspring)</span>
Answer:
I'm a eukaryotic, plant cell. I would be the central vacuole that stores excess water, food, and waste. There's only one of me in a plant cell. If I weren't in the cell, it would collapse or burst, because it well lose its turgor pressure. Moreover, the cell won't have enough space to store all the water and molecules needed for conducting photosynthesis. I resemble the stomach in a human body; a stomach stores food and water for later use.
A molecule that functions in maintaining and/or reproducing life is called the molecule of life. The four molecules of life are proteins, carbohydrates, lipids, and nucleic acids. Each of the four groups is vital for every single organism on Earth. Without any of these four molecules, a cell and organism would not be able to live. They structurally or functionally for cells and mostly they are important in both ways.
.......is secreted into the bloodstream, whereas _____ is secreted into mucus such as gastrointestinal fluid, colostrum, saliva, tears, and sweat:
a. Monomeric IgM; pentameris IgM
b. Monomeric IgA; dimeric IgA
c. Monomeric IgA; dimeric IgM
d. Dimeric IgA; monomeric IgA
Answer:
b. Monomeric IgA; dimeric IgA
Explanation:
IgA is a class of antibodies that are found mainly in body secretions. In sweat, tears, saliva, mucus, breast milk, and gastrointestinal secretions, IgA is secreted as a monomeric antibody. Smaller quantities of this class of antibodies are also present in blood and lymph. However, IgA is present in a dimeric form in the bloodstream. It makes up 10–15% of all antibodies in the blood. The main function of this class of antibodies is to give localized protection of mucous membranes against bacteria and viruses.
