The correct anser is option (A) During an especially cold winter, brown squirrels that had thick coats survived at higher rates than brown squirrels whose coats were not as thick.
Natural selection is a mechanism of evolution proposed by Charles Darwin. It is the differential survival and reproduction of individual due to the difference in the phenotype. Over time, this process results in populations which are better adapted to their environment as they tend to survive and produce new offspring. The brown squirrels with thick coat survive at a higher rate than the brown sqirrels without the thick coat. Thick coat is a adaptation for survival in cold winters which are chosen over the other and allowed to reproduce.
Answer:
A. Hippocampus
Explanation:
The Hippocampus in the limbic system is important for sorting out and storing in new information. This is also responsible for connecting memories to one another by getting different senses and emotions in place.
Answer:
Option A, 30 C
Explanation:
Plants are able to produce oxygen through the process of photosynthesis and photosynthesis is well carried in the presence of light at a warm temperature of 28 degree Celsius. The rate of photosynthesis falls if the temperature rises above 28 degree Celsius and with falling rate of photosynthesis, rate of oxygen production also falls.
The rate of photosynthesis and hence the oxygen produces also falls when the temperature falls below 28 degree celsius.
Since, the nearest temperature range is 30 degree celsius thus option A is correct
Answer:Mutations are irreversible and are passed on to the daughter cells during mitosis. Certain genes are involved in the maintenance of normal cell growth patterns
Explanation:
Generally, any "thing" has many different qualities. If it shares roughly half these qualities with another "thing" they could be said to be very different and yet similar. <span>In the case of cells, plant cells and animal cells both have a nucleus, protoplasm, vacuoles. Plant cells have cell walls and a more rigid structure</span>
