The phase in the cardiac cycle when the mitral valve is closed and the aortic valve is open is the systolic ejection phase (Option D). It is the second phase of the ventricular systole.
The cardiac cycle is a sequence of contraction and relaxation of the atria and ventricles to pump blood throughout the body.
This cycle (cardiac cycle) can be divided into two major periods: diastole and systole.
The diastole is when the heart relaxes and refills with blood, while the systole is when the heart contracts and pumps blood.
The systolic ejection phase is the second phase of the ventricular systole where blood is pumped from the ventricle.

<span>It would depend on the method of decolorization. The most common one is by using Acetone-alcohol. When your slide are decolorized too much with Acetone-alcohol, cells will appear to be pink since the crystal violet are washed out.</span>
---- *Well, since there is really no specific ecosystem that was asked about in the question, I will just list some common and basic abiotic factors found throughout most ecosystems (maybe you can match this with the ecosystem you are talking about).

Abiotic factors: nonliving parts of an ecosystem
Some abiotic factors include: ROCKS, SOIL, AIR, SUN, WATER, ETC.
<span>Functional traits can be shared between organisms with divergent SSU rRNA sequences because functional traits may evolve independently, be shared through horizontal gene transfer, or be lost in divergent lineages.
Functional traits are characteristics that define our behavior.
