<span>When
a plant opens and closes its stomata, it is maintaining its respiration and
helps the Earth’s breathable atmosphere. Stomata (stoma) by dictionary
definition is a small opening on a plants’ epidermis (mostly on leaves) with
which gas exchange happens, carbon dioxide in, oxygen out.</span>
Oceanic plate crust is thinner and denser than continental crust, so the thinner oceanic crust gets bent and pulled under the continental crust. this creates a subtraction zone.
mv^2 =2* e*40k J/Cv= sqrt(2* e*40k/m)
mv^2/r = F centripetal = evB2* e*40k/(210*sqrt(2* e*40k/m)*e) =BB=√e∗80,000∗m−−−−−−−−−−−/210
Answer:
Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) ... Multiply the percentage of time in each phase by the total time of the cell cycle (720 minutes) and this gives you an estimate of the time spent in each phase.
Explanation:
Answer: Option B.
A see saw, chin raise.
Explanation:
A lever is a machine that can rotate and consist of a beam which is pivoted to fulcrum.
There are three classes of lever, the first class lever, second class lever and third class lever. These three classes of lever are classified base on the positions of effort, fulcrum and Load.
In first class lever, fulcrum comes between the effort and load. Examples is scissors , see saw, pliers. This is because effort is applied on the one side of the fulcrum and load is on the other side. Therefore, the childhood demonstration of first class lever motion is see saw and chin raise.
In the second class lever, load come between effort and fulcrum e.g wheelbarrow, bottle opener.
In the third class lever, effort comes between fulcrum and load e.g hammer, broom.
