<span>Well, since there is little genetic variation, all the animals in the population are fairly similar, from a purely physical standpoint. Therefore, if there was some new form of whale lice that kills northern right whales, then presumably at least nearly 1/3 of the population would be vulnerable to this new form of whale lice. This is over simplified, but in essence a huge portion of the population is much more vulnerable to a single threat due to common disease resistances, or the lack thereof.</span>
Answer:
The correct answer is B.surviving droughts
Explanation:
Genetic engineering is involved in producing disease-resistant crops and even drought-resistant crops. This is done with the help of transferring the valuable genes to the crop that gives them the capability to survive the drought condition for longer times.
For example, Japan used a particular gene of rise that are found in the dry regions of philippine and transferred the gene to the rice variety they used to grow and saw that their variety now gives more production during drought.
Thus, surviving drought is an advantage that crops may attain through genetic engineering.
<span>The answer is columnar
epithelium. This type of epithelium with tall columnar cells is adapted for absorption
and is also protective. The epithelium of the proximal convoluted tubule has microvilli
that increase the surface area for reabsorption of water and minerals back into
the bloodstream. </span>
Answer:The North frigid zone, between the Arctic Circle 66.5° N and the North Pole 90° N. Covers 4.12% of Earth's surface. The North temperate zone, between the Tropic of Cancer 23.5° N and the Arctic Circle..
