The correct answer is "Glycolysis occurs in the cytoplasm; Cell respiration occurs in the mitochondria."
Nuclear maturation encompasses nuclear envelope breakdown, meiotic spindle assembly, and chromosome segregation. Cytoplasmic maturation involves major changes in oocyte protein translation and cytoplasmic organelles and is poorly understood.
In the nematode Caenorhabditis elegans, sperm release the major sperm protein (MSP) hormone to promote oocyte growth and meiotic maturation.
Large translational regulatory ribonucleoprotein (RNP) complexes containing the RNA-binding proteins OMA-1, OMA-2, and LIN-41 regulate meiotic maturation downstream of MSP signaling.
To understand the control of translation during meiotic maturation, we purified LIN-41-containing RNPs and characterized their protein and RNA components. Protein constituents of LIN-41 RNPs include essential RNA-binding proteins, the GLD-2 cytoplasmic poly(A) polymerase, the CCR4-NOT deadenylase complex, and translation initiation factors.
RNA sequencing defined mRNAs associated with both LIN-41 and OMA-1, as well as sets of mRNAs associated with either LIN-41 or OMA-1. Genetic and genomic evidence suggests that GLD-2, which is a component of LIN-41 RNPs, stimulates the efficient translation of many LIN-41-associated transcripts.

Answer:
C.The percentage of essential body fat is the same for both males and females.
Explanation:
Among the given statements, only C is incorrect. Typically, on average, women have 5-12% more body fat than men. This has been mainly linked with the female hormones (e.g. oestrogen). Firstly, women can store more fat in their bodies due to the presence of excessive adipose tissues. Secondly, they are suppose to carry a child at some stage of their life, so a better food supply and protection is necessary.
On the other hand, rest of the options are true. Essential body fat is always required by body. It accounts for 3% of total body wight. And, it can be found in organs, bones and muscles at different percentages.
Answer:
A cell that contains a nucleus and other membrane bound organelles.
Explanation:
There is really no change in cardiac output, there is increased heart rate and a decrease in systolic volume.Although, it is common that after donating blood, vasovagal syncope occurs.
This is basically that the body reacts to de lack of volume, the brain detects an stimulator effect on the vagus nerve, lowers the heart rate and the person feels dizzy or falls, without major consequences.
