1 answer:

7 0

Prokaryotes have no cell nucleus and no membrane enclosed organelles. Prokaryotic DNA can be found in a coiled loop floating in the cytoplasm in a region called the nucleoid (meaning nucleus-like). In other words, the nucleoid is the area in a prokaryotic cell where DNA is located.

In eukaryotic cells, DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. It is present in this compartment in the form of linear chromosomes that together constitute the genome.

Explanation:

In the given table showing the average daily calories requirement according to the weight of the adult men. Which is as follows:

weight daily intake

132 2250

154 2450

176 2650

198 2850

220 3050

242 3250

In this, the highlight weight and required calories should be taken by the man who does not perform any physical exercise but according to the question a man with 154 lb perform a moderate exercise, and according to the CDC a 154 lb men can burn anywhere between 140 and 295 calories in 30 minutes by moderate exercise for an hour.

Thus, the total calories he takes: 2700

burn by exercise: 295

should take: 2450

then = 2700 - (2450+295)

= 50 calories over the limit that will have negligible effect on the weight.
