Answer:
Option C us correct.
km • m/S
Explanation:
This is because momentum is result of mass and velocity of an object. Momentum is a vector quantity that is it has magnitude and it's direction is in form of three dimensional.
From the option C, kilometer there is not a unit for mass or velocity it it is a unit for distance, therefore it is incorrect.
Answer:
Increase EDV and therefore, increase stroke volume.
Explanation:
EDV is the volume of blood which filled the ventricle before its contraction while ESV is the volume of blood remain in ventricle after ejection.
When venous return increases, this will increase the pressure on ventricle contraction which can lead to eject of addition blood returned to it.
So, increase in EDV results in an increase of stroke volume (SV).
Answer:
42
Explanation:
The mass number of an atom is equal to the number of protons plus the number of neutrons in a nucleus
This atom Mo-96 has an atomic number of 42 and so has 42 protons in the atom.
It’s what the plant uses to produce food for itself.
Answer:
Chlorophyll "a"
Explanation:
The reaction centers of the photosystem have chlorophyll "a" molecules. The chlorophyll "a" that functions as a reaction center for the photosystem II has absorption maxima at 680 nm and therefore, it is called P680. The reaction center of photosystem I also have chlorophyll "a" molecules that have the absorption peak at 700 nm. The chlorophyll "a" molecules serving as reaction centers transfer the photoexcited electrons to a primary acceptor during the light-dependent phase of photosynthesis.
