Answer:
The options are:
A. Gravel
B. Sand
C. Silt
D. Clay
E. Mud
The answer is A. Gravel
Explanation:
Meiofauna are small benthic invertebrates which live in aquatic habitat. They are suited for both marine and fresh water environments.
Gravel aren’t tightly packed together in large quantities when compared with the other options such as sand, silt, clay, mud. This makes it possible for more aeration and the presence of more oxygen at the soft-bottomed intertidal community.
Answer:
False, chemical energy is not transfered or converted into cellular energy
Explanation:
Answer:
To study the importance of the RNA telomer element, we can evaluate it by generating an in vitro state where all the purified components are included, organizing two groups, one of them will have an RNAase and the other will not, if it is observed that the telomeres extend to the component of the RNA, in the set where there is no RNAase, longer telomeres could be observed, if there were no influence of the RNA, the length in both groups would be the same
Answer: The correct answer is -
D) giraffes having increasingly longer necks over time.
Natural selection is an evolutionary mechanism that was proposed by Darwin.
According to this mechanism, organisms that are better capable of adapting to their changing environmental conditions, survive and increase their number through reproduction whereas other are eliminated from the population.
Example - Long neck of Giraffe, which is much elongated, lofty stature, that was beautifully adapted for browsing on the higher tree branches. This was an adaptation with slow and gradual change in the gene frequency as the lower vegetation was eaten by other animals. Due to this, giraffes had to search for other source (that was higher tree branches).
This is considered as a peculiar example of natural selection.
