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.
I Think this is the cell cycle. S phase is the synthesis phase. It is the replication of the DNA and splitting of the cytoplasm.
Answer:
Enzymes are proteins in composition which are a very essential component of the metabolic reactions in the living organisms.
The properties of enzymes allow the enzymes to be used as a reaction catalyst which increases the speed of the reaction.
The enzymes lower the threshold energy of the chemical reaction and thus increases the rate of reaction.
The enzyme catalyses very complex reactions like a breakdown of complex biomolecules as well as the formation of complex biomolecules.
The active sites are present on the enzymes which bind the substrate molecule and increases the pace of reaction.
The provided question is incomplete as the cross in between parents, however the cross between in red and white bred parents.
Answer:
The correct answer is : five red/white chickens.
Explanation:
Parents should be homozygous for feather color, each offspring will inherit F from one of the parent, and the f allele from parent 2. So, every offspring will have the genotype F and f and will have white and red fathers.
Thus, the correct answer is : five red/white chickens.
