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.
gene flow or migration between two populations will help maintain similarities between the species, therefore preventing (or slowing down) the process of speciation. and when the environment changes rapidly, this can cause an overall decrease in population size because of a failure to adapt adequately to environmental changes. i hope this helped <3
<span>DNA stands for deoxyribonucleic
acid. The deoxy- in the DNA is a short term for deoxyribose. The nucleic acid
molecule has three parts; sugar, phosphate and a base. The phosphate in the DNA
acts as a backbone of the molecule. It is also responsible for the DNA’s
‘double-helix’ structure. The base has four codes namely adenine, thymine,
cytosine and guanine. Adenine and thymine are bse pairs whereas cytosine and
guanine are base pairs. They are not to be interchanged. Resulting in one cause
mutation in the gene. </span>
I believe the answer is D) reactivity. Hope this helps. (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧
The biological basis for assigning all human beings into a singe species is that there so many, even tons of living organisms living on earth. These organisms differ in their external and internal organs and so to differentiate them from them, they are being classified into kingdoms then classes then phylums then family.
