Answer:
<u>Red blood cell in humans -</u> it has no nucleus. Hence it offers the cell to carry more haemoglobin.
- they are disc shaped allowing them to pass through narrow capillaries.
<u>Root hair cells in plants-</u> they have a large cytoplasm which enables them to take water from the soil.
<u>White Blood Cells in humans -</u> they have lobed nucleus and so can change their shape to pass through narrow capillaries.
- <em><u>HOPE IT HELPS...</u></em>
They probably fall into the bacteria catagory
The number of predators and preys change from time to time following
cycles. Whenever there is fewer prey, predators start dying because they
have not enough to eat; however, that provokes the population of prey
to be increased while there are fewer predators. So if suddenly the
number of prey gets bigger, regardless of the number of predators, the
cycles get disturbed by this sudden occurrence. The predators will get
more to hunt, therefore getting more violent.
If a hypothesis is supported consistently by different observations or experiments, it may be advanced to the level of a(n) <u>theory</u>.
