Answer:
By increasing the enzyme concentration, the maximum reaction rate greatly increases. Conclusions: The rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.

Explanation:
Gregor Mendel is known for his study on pea plants about the inheritance.
To understand the inheritance, he had experimented with pea plants.
He had performed a cross-pollination production method between two different plants of the pea and prevented self-pollination in it.
The blood travel to your liver before transporting nutrients to other parts of your body in order to filter out substances that are not needed for the body. The liver <span>regulates the composition of blood, including the amounts of sugar (glucose), protein, and fat that enter the bloodstream. It removes bilirubin, ammonia, and other toxins from the blood. </span>

Explanation:
Through the mechanism of RNA interference (RNAi), short RNAs can inhibit gene expression. RNAi can function at transcriptional level, translational level, and mRNA stability.
RNAi mechanism has numerous biological functions; it can affect development, for instance in the worm C. elegans, or it can be utilized by plants to evade viral infection.
These short RNAs (abt 23 bp long) also known as siRNAs (short interfering RNAs) are products of long dsRNAs which are cleaved by nuclease Dicer. The siRNAs regulate a nuclease complex called RISC (RN-induced silencing complex) leading to repression of gene expression via three distinct ways;
a) Destroy mRNAs that have complementary sequence with the siRNA
.
b) Inhibit translation of mRNAs that have complementary sequence with the siRNA.
c) Induce chromatin modification within the promoter of these homologous (complementary) genes, thus silencing them.
