I believe it is idiopathic.
Answer:
B Physical separation of populations prevents interbreeding and mixing of gene pools.
Explanation:
Geographic isolation means two populations are unable to reproduce with one another. This means that over time, the variation in the gene pool will be different for one group compared to the other, and the species will genetically diverge from one another. resulting in speciation.
Answer:
D. Tricuspid → right ventricle → pulmonary valve → pulmonary circulation
Explanation:
The circulatory system is the system of organs and blood vessels which is associated with the circulation of the blood in the body.
The circulatory system is divided into two portions: the systemic circulatory system (body) and the pulmonary circulatory system (lungs).
The vena cava brings the oxygen-poor blood from the body to the right atrium from where the blood is transferred to the same side of the ventricle controlled by the tricuspid valve (atrioventricular valve).
From the right ventricle, the blood is pumped to the pulmonary artery which transports the blood to the lungs where the oxygen will be exchanged.
Thus, Option-D is correct.
<span><span>There are choices for this question namely:
A. Its photons have the shortest wavelength in the visual spectrum
B. Its photons have the highest energy in the visual spectrum
C. Its photons have the longest wavelength in the visual spectrum
D. It is not considered a part of the visual spectrum
The correct answer is that </span>its photons have the longest wavelength in the visual spectrum<span>. Chlorophyll, being green in color (around 495 to 590 nm wavelength), reflects this wavelength; not absorbed. Mostly, the chlorophyll absorbs longer wavelengths of light such as red (around 680 nm wavelength) and blue to violet (around 400 to 480 nm wavelnegth). </span></span>
So that they could adapt to there habitat
