The structure of the skin is an effective barrier against bacteria. The multiple layers of epidermis, while can be invaded by foreign organisms, has a high turnover rate which means it is constantly shedding, therefore even the bacteria is shed protecting the body.

madreJ [45]

Answer:

Population dynamics can be described as the size of a particular population and the environmental and biological factors which influence it.

For human populations, a population which is greater than the resources can be controlled by decreasing the number of births in that population. It can be controlled by people migrating from the place due to less resources available.

For animals, the population can be controlled by increasing the amount of predators for the particular population so that they decline in number. Or shifting of the organisms can be done to places where there are enough resources available.

A scientist investigated DNA replication in two groups of cells, labeled A and B. She injected radioactively labeled nucleotides
Maksim231197 [3]

Answer:

D. The cells in group B are prokaryotic because they replicate their DNA in the cytoplasm.

Explanation:

The cells of group A are prokaryotic because it is prokaryotes which do not have a double membranous structure called nucleus for storing their genetic material. The genetic material of prokaryotes is spread in the cytoplasm in the form of a circular DNA which is called as nucleoid. Since they do not have a separate organelle like nucleus for storage of their genetic material, they are bound to replicate their DNA in the cytoplasm. In contrast to prokaryotes, eukaryotes have nucleus for storage of their genetic material and in eukaryotes replication is an exclusively nuclear event.
