Answer:
convergent plate boundary.
Explanation:
When they collide this is what is makes.
Answer:
B. Electron Cloud
Explanation:
It would not be A because, electrons orbit the nucleus so they cannot be physically IN it.
It cannot be C either because, we are talking about an atom not a cell. Mitochondria is only present in cells.
They have different sizes and shapes. An example would be a tomato and a grape. Tomatoes are red, grapes are purple/green. Grapes are small, tomatoes (most of them) are large. This must be because the cells that make the tomatoes differ from the one that makes the grapes. Hope this helped/made sense :)
Wild Bedbugs become insecticide resistant because of the mutations and natural selections.
<h3><u>Explanation</u>:</h3>
As the huge amount of pesticides and insecticides are sprayed in the rooms for cleaning, the pests and insects like bedbugs dies in huge portions because of the toxin. But some of the bedbugs remain alive as they have mutations that help them to detoxify the toxins given, or bypass the metabolic processes so that the toxins don't hamper them much.
Now as the population becomes very small(bottle neck effect), the nature selects these organisms over the other to propagate more sufficiently and enormously. As the nutrients and supplies are also available, so the bedbugs don't suffer any lack of nutrition which can be a determining factor of their population.
Thus the wild bedbugs become resistant to insecticides while the experimental one remain succeptible to insecticides.
