B and D are the correct answers for this question
Options are:
a) lymph.
b) interstitial fluid.
c) extracellular fluid (ECF).
<span>d) plasma.
</span>
All the following are correct terms for this fluid except lymph.
The interstitial fluid surrounds the cells in the body. The other major component of the ECF is the intravascular fluid of the circulatory system called blood plasma<span>.
</span>Lymph is<span> a fluid which contains infection-fighting white blood cells, throughout the body.</span>
Answer:
The correct answer is option B.
Explanation:
On seeing the question, it is clear that it is based upon the concept of semi-conservative theory for the replication of DNA. It is mentioned that when the bacteria were grown on N-15, the mass was 55 fg. Now, after two generations, the DNA would comprise N-14 and the mass of them will be 5.4 fg.
The average mass would be = 5.4 + 5.5 / 2 = 10.9 / 2 = 5.45 fg. The mass of the bacteria isolated from the culture would possibly contain both the masses. That is, the mass of DNA with N-14 only would be 5.4 fg, and the mass of DNA with both N-15 and N-14 would be the average, that is, 5.45 fg.
Answer:
The correct answers are options A, C and D.
Explanation:
As sexual reproduction enhances the genetic diversity, thus, the procedure entirely enhances the fitness of the population. The sexual females are only half as associated with their offspring in comparison to the asexual females. This is known as the cost of meiosis, this signifies that there is a dramatic decline in the relatedness in the generation of the out-crossed sexual offspring.
According to the Red Queen hypothesis, parasitism encourages sexual reproduction in the host and an evolutionary trade-off between virulence and transmission.
