Answer:
Niacin can be prescribed to therapeutically lower cholesterol levels.
Explanation:
Niacin, known as vitamin B3, is used to reduce the risk of heart attack or stroke in people with high cholesterol. Niacin has gained popularity in the last 50 years and is mainly used to raise the level of HDL (high density lipoprotein) cholesterol, also known as good cholesterol and lowering bad cholesterol levels.
However, niacin can cause health damage, so it should always be used with medical supervision.
Liver- a vital organ only found in vertebrates which detoxifies various metabolites, synthesizes proteins and produces biochemicals necessary for digestion and growth. In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm.
Answer: Layer a is 500 million years old.
Explanation:
Trilobite is a member of the group of extinct arthropods found as fossils and they can be identified by the three-lobed as well as three segmented forms. These were the marine animals. These were appeared initially in the Cambrian Period. They used to live 542 million years ago so the fossils can be estimated to be aged of 500 above years old. These animals used to dominate in the sea area.
Answer:
The answer is A.
Explanation:
Phylogenetic trees are only concerned with hard data (time points of when species evolve) and not soft data like how great a species is.
Answer:
The correct answer would be - wildtype.
Explanation:
Let assume there are four genes which are :
A-B-C-D
In mutant first, the genotype would be:---a-b-C-D
In the mutant second, the genotype would be:--A-B-c-d
If both of these genotypes are crossed with each other, the recessive genes a, b of mutant first is dominated and masked the expression by the dominant genes present in the mutant second.
Similarly, the recessive genes of the mutant second are dominated and masked expression by the dominant genes of mutant first. This is possible only due to different genes are present in mutants.
Thus, the correct answer is - The correct answer would be - wildtype.
