Answer:

10 per 1,000.

Explanation:

The death rate and birth rate affects the population dynamics of the particular area. The birth rate increases  the population size whereas the death rate decreases the population size.

The death rate of a population can be calculated by the following formula:

Crude death rate = total death/ total population

Here, total death = 1,000 and total population = 100,000.

Crude death rate = 1,000/ 100,000 = 0.01 or  10 per 1,000.

Thus, the correct answer is option (c).

Jobisdone [24]

Answer:

Only the extracts from heat-killed cells treated with RNase are unable to transform nonvirulent bacteria into virulent bacteria.

Explanation:

The experiment by Avery, McCarty and MacLeod aimed to identify Griffith's "transforming principle," which is a principle that explains how transformation is a way of recombining, exchanging, or transferring genetic information between organisms or from one organism to another. For this, they used cell that were heat inactivated and purified the transforming principle of these cells.

The purified cells did not give positive results in the tests done by the scientists, but they presented transformants very similar to the DNA. However, Avery suspected that the result should be reinterpreted and that the molecule was not a DNA. This is because RNA degrading enzymes had no effect on the transforming principle and only RNase-treated heat-killed cell extracts are unable to transform non-virulent bacteria into virulent bacteria.

A primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak

<h3>What is antigenic drift?</h3>

Antigenic drift is a phenomenon that causes small changes or mutations in the genes of influenza viruses leading to changes in their surface proteins of the virus, which are HA (hemagglutinin) and NA (neuraminidase).

For this reason, new influenza vaccines are produced yearly to alter the effects that may emerge as a result.

Thus, a primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak
