Answer:
24μm³
Explanation:
According to this question, a cell, which is said to have the shape of a rectangular prism have the following dimensions:
Length = 4μm
Width = 2μm
Depth = 3μm
Since the cell has the shape of a rectangular prism, the formula for volume of rectangular prism, which is V = l × b × d
Volume of the cell = 4μm × 4
3μm × 2μm
= 24μm³
A. The concentration of water should be higher on the outside because it allows water to slow into the cell to balance the concentration.
Answer:There is a fundamental difference in the way energy and matter flows through an ecosystem.Matter flows through the ecosystem in the form of the non-living nutrients essential to living organisms. When a living organism dies, nutrients are released back into the soil. These nutrients then are absorbed by plants, which are eaten by the herbivores. Matter, once again, is passed on. The herbivore is eaten by a carnivore (and matter is yet again transferred therein). Ultimately, when the carnivore dies, matter is returned back to the soil by the decomposers and the cycle repeats. So you see, matter is recycled in the ecosystem.Unlike matter, energy is not recycled through the system. A part of the energy is lost at each stage.
Explanation:
Answer:
The answer is E.
Explanation:
In vivo or in vitro evolution (Directed Evolution) is a technique used by genetic scientists to push the change in nucleic acids or proteins in a specific direction to get the end results that they want.
And high-fidelity polymerase is used to get a replica of the target DNA that has less errors.
So the situation given in the question where researchers use a higher-fidelity DNA polymerase in vitro evolution, the mutation rate would most likely be lower because of the high-fidelity DNA polymerase.
I hope this answer helps.
Answer:
C. capillaries connect arteries and veins.
Explanation:
A is false, veins carry blood towards the heart.
B is false because arteries are the thickest blood vessel.
C is completely true
