Answer:
<em>The correct option is D) How is the number of frogs in Massachusetts affected by pollution</em>
Explanation:
A scientific question can be described as a question which can be answered through the scientific method of research. Based on the scientific question, a hypothesis can be formulated. For example, for the option D, the hypothesis can be 'if the pollution increases, then the number of frogs decreases.' A hypothesis is a tentative statement which can be tested through experiments. Based on these experiments, results are formulated and conclusions are drawn. The question mentioned in option D can be answered through this method hence, it is the correct option.

Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.

Mrs. Lopez has the most difficulty initiating digestion of proteins after her stomach is removed. The correct option is C.
Explanation:
When the stomach is removed due to complications such as in cancers the food eaten directly goes to intestine. Without stomach Mrs Lopez will have difficulty in starting the digestion of protein.
The digestion of protein takes place and starts in the stomach and duodenum of intestine. There are enzymes as pepsin, trypsin and chyomtrypsin secreted by stomach and pancreas. Pepsin breaks the peptide bonds of protein.
The HCl and the enzymes in stomach initiates the process of digestion of protein. The amino acids formed are ardent in various metabolic processes and repair.
lipids and carbohydrate digestion starts from the mouth only as salivary amylase and lipase initiates the process.
