The large size of the daughter oocyte after meiosis II results from the uneven distribution of the cytoplasm, which allows the z

ygote to divide mitotically before it begins growing.A) True B) False

Answer:

True

Explanation:

Oogenesis includes the formation of one egg cell from a single oocyte or egg mother cell. The diploid primary oocytes in the ovaries enter into the first meiotic division and form a haploid secondary oocyte and a haploid first polar body. After fertilization, the secondary oocytes complete the meiosis-II and forms one large ovum and a second polar body. The ovum formed by meiosis-II is much larger than the second polar body due to the unequal distribution of cytoplasm during meiosis-II. This imparts enough amount of cytoplasm in the zygote to support the mitosis without any cell growth.

andre [41]

Answer:

The correct answer is - drinking more water and fluid.

Explanation:

Hypernatremia is a condition in which the body losses too much water or body fluid and the case of dehydration took place which leads to the low serum sodium concentration. The serum sodium concentration is under 145 mmol/L in this condition.

This occurs due to loss of body fluid due to sweating, diarrhea injury, or drinking very little water. To correct or treat this treatment in a healthy person it is asked to drink plenty of water and other fluids to maintain body fluids.

Enolase is an enzyme that catalyzes one reaction in glycolysis in all organisms that carry out this process. The amino acid sequ
lorasvet [3.4K]

Answer:

a) The response indicates that a pH below or above this range will most likely cause enolase to denature/change its shape and be less efficient or unable to catalyze the reaction.

b)The response indicates that the appropriate negative control is to measure the reaction rate (at the varying substrate concentrations) without any enzyme present.

c)The response indicated that the enolase has a more stable/functional/correct/normal protein structure at the higher temperature of 55°C than at 37°C because the enzyme is from an organism that is adapted to growth at 55°C.

Explanation:

Enolase catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate during both glycolysis and gluconeogenesis.In bacteria, enolases are highly conserved enzymes and commonly exist as homodimers.

The temperature optimum for enolase catalysis was 80°C, close to the measured thermal stability of the protein which was determined to be 75°C, while the pH optimum for enzyme activity was 6.5. The specific activities of purified enolase determined at 25 and 80°C were 147 and 300 U mg−1 of protein, respectively. Km values for the 2-phosphoglycerate/phosphoenolpyruvate reaction determined at 25 and 80°C were 0.16 and 0.03 mM, respectively. The Km values for Mg2+ binding at these temperatures were 2.5 and 1.9 mM, respectively.

Enolase-1 from Chloroflexus aurantiacus (EnoCa), a thermophilic green non-sulfur bacterium that grows photosynthetically under anaerobic conditions. The biochemical and structural properties of enolase from C. aurantiacus are consistent with this being thermally adapted.
