Read the following passage from the Biology Department at University of California, Berkeley. Northern elephant seals have reduc

ed genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely. Which of the following best describes how the population has evolved?

babunello [35]
<span>I could only imagine that the nurse would be a bit taken aback that the paitent is using mineral oil and shoving it up their own buttocks. The nurse would report this to the doctor on call or the RN of which she can discuss proper remedy for the client. Proper responses from the nurse would also include the how to's in doing this correctly if this indeed is what the paitent is wanting to continue as far as short term relief over finding out what is causing the problem in the first place.</span>

Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain protei
valkas [14]

Answer:

From the given information, the transport of glucose in blood across the red blood cells takes place by facilitated diffusion, that involves the spontaneous passive-transport with the help of trans-membrane proteins or transporter proteins to move the ions or molecules down the concentration gradient.

While the transport of glucose in intestines take place via active transport mechanism. It takes place from gut into intestines. It occurs against the concentration gradient with the help of energy molecules like proteins.

Mariyam, a marine biologist, measures the length of a great white shark at 4.5 m long and its teeth at an average of 50 mm long.
Oksana_A [137]
Metres are exactly 100 cm in length, the easiest way to go from metres to centimetres is to simply add the extra 1 or 2 zeros, so 4.5 metres would be 450 centimetres.

As for the millimetres, 1mm is equal to 0.1cm, once again, just move the decimal forward by one numeral, and you'll have the converted value, making 50mm = 5.0cm.

Your shark would be 450cm long and have teeth with an average length of 5cm.
