The answer is C
if you kill all the sea otters (which is wrong) then there is nothing to kill the sea urchins which then the sea urchin population will increase. Because sea urchins feed on kelp and there are so many of sea urchins, it requires more kelp to be eaten. Last, the kelp population is low because all the sea urchins ate most of the kelp
A. endoskeleton
Endoskeleton is not a characteristic of Arthropods that has attributed to their diversity and success. Endoskeleton is defined as inner characteristics of the skeletal feature of an organisms such as bears, humans, fish and etc.
Exoskeleton on the other hand is the trait by which arthropods posses. It is skeletal feature that is described outside or is extrinsic, this is evident as crabs have their skeletons outside of their body.
Course alteration is the first to be utilized to find the example, and just with the low power objective. When seeing an example, you should dependably utilize the lower control target focal points first. Low power focal point gives the most stretched out field of view and makes it less demanding to discover the example when you look through the magnifying lens. Finding the example at high power, without first focusing it in the field of view at low power, is almost outlandish.
It would be mitosis.
Mitosis is when a cell splits into two cells, and is the exact same copy.
