Answer:
Organelles in a cell are essentially the same as organs in an organism. The mitochondria is the powerhouse of the cell, as we all know. It creates ATP, which is what gives the cell energy. This is similar to how we consume food and create energy from it. Cell membranes are similar to skin, as they keep needed things in, and unwanted things out. Our cells need water too, as it helps create the cytoplasm. We need water to keep us alive and well, as it helps to create many of our needed bodily fluids, and rid us of toxins.
Answer:
The correct option is <em>B) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.</em>
Explanation:
Organism of a population might have genetic variations in them due to many reasons. The species of a population which are better adapted to live in a particular area are able to survive and produce more offsprings. As a result, that particular area increases in that genetic variant.
In the above scenario, some of the wolves had variants in their digestion which made them better adapted to live with the humans as they could eat wheat, rice etc. The wolves which did not have variants in their digestion couldn't survive in the human areas.
They form in very bad storms or changing temps!
Answer:
Option (2) and (3).
Explanation:
Cancer is the uncontrolled division of the cell that might results in the loss of apoptosis in the cells. The cancer cell shows the property like angiogenesis and loss of contact inhibition.
Both the hereditary factors like mutations in some gene and environmental factors like any mutagen may inhibit the process of the cell division. Both these factors mainly inhibits the gene that are responsible for the regulation of the cell cycle like p53, Rb.
Thus, the correct answer is option (2) and (3).
