Answer:

(B) semiconservative.  

Explanation:

According to the model proposed by Watson and Crick, the DNA molecule consists of two polynucleotide chains arranged on a helix around an imaginary axis, rotating to the right (a double helix). That is, the DNA molecule is in the shape of a spiral staircase, in which the "steps" are made up of nucleotide nitrogen bases and the "handrails" are covalently linked phosphate and sugar - so it is said that DNA is shaped like a helical ribbon. Also according to Watson and Crick DNA replication is semi-conservative, because each strand of DNA will give rise to another strand that will be complementary to its nucleotides.

Two cells in the same organism differ only in the number of chloroplasts they contain. The first cell has multiple chloroplasts,
FromTheMoon [43]

Answer;

The second cell would not be able to produce as much food because it could not capture sunlight.


Explanation;

The first cell has multiple chloroplasts, and the second cell has very few which means the cell with more chloroplasts would make more food.

Chloroplast is an organelle is the cell where the process of photosynthesis (process in which plants make their own food) takes place.

A cell with multiple chloroplasts would make more food through photosynthesis compared to a cell with few chloroplasts.
