Answer:
The t-test
Explanation:
<em>The researcher should use a t-test to compare the two means and check if they are significantly different from each other.</em>
In using the t-test, both null (H0) and alternate (H1) hypothesis are made such that:
Thereafter, the value of t is calculated and compared to its critical value on the table. The formula for calculating the t goes thus:
where, Y1 = mean of population 1, Y2 = mean of population 2, S1 = variance of population 1, S2 = variance of population 2, n1 = number of individuals in population 1 and s2 = number of individuals in population 2.
<em>At the end of the day, if the calculated t value is more than the critical value of t, the H0 is rejected and it shows that the two means are significantly different. Otherwise, the H0 is accepted and this shows that there is not significant difference between the mean of population 1 and that of 2.</em>
The answer is C: <span>The Neanderthals cared for the wounded and the elderly. The fact that the skeleton showed signs of broken bones that had healed indicated that the individual had been nurtured back to health after injury. The loss of teeth showed that the individual had lived to an old age.</span>
In a viral structure, the capsomere is made up of small protein subunit called capsid. The correct option is b.
<h3>What is capsid?</h3>
Viral capsids are nanometer-sized canisters with complex mechanical characteristics that encapsulate the viral genome inside one host, transit it, and then release it inside another host cell.
Capsids are small protein subunits that make up the b. All viruses contain DNA as their genetic material. Glycoproteins aid virus attachment to the host cell.
Thus, the correct option is b.

Answer:
30% Thymine
Explanation:
If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal.
Therefore, that leaves us with 40% between Cytosine and Guanine. Since the ratio between them would be equal, it gives us 20% of Cytosine and 20% of Guanine.
<u>Therefore:</u>
30% of A + 30% of T + 20% of C + 20% of G = 100% DNA
