Answer:
I believe that it is D.
Explanation:
If ice caps are melting, and polar bears use the ice flows to get their food, then the polar bears can't use the ice to get food. so, the polar bears most likely are expanding their diets to adapt to their surroundings. So, polar bears are probably moving off the sea ice and eating other foods.
<span>The juxtaglomerular apparatus is a structure (formed by the distal convoluted tubule and the glomerular afferent arteriole) with the function in the regulation of blood pressure and the filtration rate of the glomerulus. Its primary components are:

Mitosis makes copies of the host, so it is a good option to increase the population because it is a fast process. Meiosis is important to create genetic diversity, because it makes four genetically different haploid cells, instead of two genetically identical diploid cells, as mitosis does.
Inheritance is the process by which traits are passed from the parents to their offspring. The basic unit of inheritance in human is the DNA. For traits to be passed from the parent to the offspring, the DNA in the cell must be duplicated and this happens through the process of cellular reproduction.
