Tropism describes a virus’s affinity for specific tissues:
a) true
b) false

B. True

Explanation:

The tissue tropism can be define as the ability of the microbe to infect specific cells and tissues of the host that supports the growth of particular microbe like virus and bacteria.

Some viruses have broad tissue tropism they can infect many cell types. Other viruese can infect only single cell or tissue type.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
