the plant body is unicellular and biflagellate.
the cell is spherical or cylindrical in shape .
the Protoplasm of the cell is always surrounded by a thin cellulose wall .
a pair of flagella of equal size is present at the anterior end. it moves by the lashing actions of the flagella.
usually two contractile vacuoles are present .

Which is true regarding the TCA cycle (Krebs cycle)? A. pyruvate is an end product of the cycle B. energy capture in the cycle i

Naily [24]

Answer: D. some components of the cycle are used as building blocks for certain anabolic pathways.

Explanation:

The citric acid cycle or Kreb's cycle is the part of the cellular respiration. It is a sequence of chemical reaction which is used by all the aerobic organisms so as to store energy by the process of acetyl CoA oxidation derived by the process of fats, proteins and carbohydrates into forms like carbon dioxide and adenosine triphosphate (ATP).

The acetyl CoA is used in the process of synthesis of fatty acids. The citrate is used for the synthesis of cholestrol. The oxaloacetate and alpha ketogluterate are used for the synthesis of aminoacids. Succinyl CoA is used for the synthesis of poryphrins and fatty acids.

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.

Very rapid (i.e. in 1-2 seconds) responses to maintain normal blood pressure during a sudden decrease in blood volume by hemorrh

Tatiana [17]

Answer:

vasoconstriction of capillaries.

baroreceptors in the aortic arch.

Explanation:

Vasoconstriction of capillaries and baroreceptors in the aortic arch are the two quick responses of body to maintain normal blood pressure during hemorrhage. Vasoconstriction is very necessary for lowering acute blood loss during hemorrhage means escape of blood from a ruptured blood vessel as well as maintain body heat and arterial pressure. The function of baroreceptors is to respond to the change in the tension of the arterial wall when blood pressure changes.
