How many atoms are there in 25 grams of calcium
Answer:
The molecular weight of calcium carbonate is 100 g per mole. 25 g of calcium carbonate corresponds to 0.25mole. 1 molecule of calcium carbonate contains three oxygen atoms. Thus, 0.25 mole of calcium carbonate will contain 0.75 moles of oxygen atoms which is equal to 0.75×6.02×10^23=4.51×10^23 oxygen atoms.

During maturation of the oocyte, what happens to the chromosomes as a result of meiosis?.
Answer:
The cell becomes haploid, with 23 single chromosomes.
Explanation:
Hope This Helps.
The process of meiosis, a form of cell division that decreases the number of chromosomes in the cell from two sets to one set, occurs as the egg matures.
The creation of gametes, which are reproductive cells with just one pair of chromosomes, depends on this process. The main oocyte, which has two sets of chromosomes, is formed at the start of meiosis. The two sets of chromosomes align into homologous pairs during meiosis I, cross across, and combine to create new genetic combinations.
Four daughter cells are created as a result of this process, and each one of them has a set of chromosomes made up of the original two sets. The four meiosis II genes are dividing to become double.

A particular molecule is 45% Cytosine. What percentage of the molecule is Thymine?
Answer:
55%
Explanation:
if the whole molecule is 100%, then cytosine plus thymine is 100%
cytosine + thymine = 100%
45% + thymine = 100%
thymine = 100% - 45%
thymine = 55%
True or False? Endurance training results in an increase in parasympathetic nervous activity and this allows for a reduced resting heart rate.
Answer:
Endurance training increases parasympathetic activity and decreases sympathetic activity in the human heart at rest. These two training-induced autonomic effects, coupled with a possible reduction in intrinsic heart rate, decrease resting heart rate.
