I believe the answer is C.
because when the dinosaurs thrived they ate most of the mammals which were small animals but when the dinosaurs went extinct the mammals grew larger in size and started to thrive.
This rock can be classified as:
an igneous rock.
Igneous rocks are made up of
randomly arranged interlocking crystals and the important minerals that can be
found in igneous rocks are feldspars, quartz, olivines, pyroxenes, amphiboles,
and mafic minerals. All of these minerals are important in the formation of
almost all igneous rocks, and they are basic to their classification.
This would be probably true if the assumption that all possible genotypic variations would be equally distributed (so we would have 25% HH, 25% hh and 2x 25 Hh). If this distribution would be true and Huntingtons disease really was a single gene dominant trait diesase, then yes, we could expect such a distribution in the population.
Kelp is a kind of a brown algae (Phaeophyceae). It is a cold-water seaweed also used as food and as a source of iodine. It is considered safer and better than any other chemicals for the body. It develops through sunlight and it gets nutrients and minerals from the water around it.
