Answer: Vertebrates are differentiated by having a vertebral column. As chordates, all vertebrates have a similar anatomy and morphology with the same qualifying characteristics , a dorsal hollow nerve cord, pharyngeal slits
Example
Vertebrates have a spine, or backbone, made of multiple disc-shaped bones called vertebrae. There are five classes of vertebrates which are: amphibians, fish, reptiles, birds, and mammals. Examples include frogs, tuna, snakes, parrots, and monkeys.
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.

A community of organisms in an ecosystems consists of grass, rabbits and wolves. It did not rain for many months. The lack of water killed the grass in the ecosystem. What effect does the drought have on the wolf population?
The rabbit population would increase causing the wolf population to increase.
The rabbit population would decrease causing the wolf population to increase.
The rabbit population would decrease causing the wolf population to decrease.
The rabbit population would increase causing the wolf population to decrease.
Answer: C) The rabbit population would decrease causing the wolf population to decrease.
Explanation: If there is no food for the rabbits, then they die, and because there are no rabbits, there is no food for the wolves so they die, simple.
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%
