sergij07 [2.7K]

Answer:

Viruses can be used to insert genetic material into cells during gene therapy

Explanation:

Gene therapy is a process used to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.

A gene that is inserted directly into a cell usually does not function. Instead, a carrier called a vector is genetically engineered to deliver the gene. Certain viruses are often used as vectors because they can deliver the new gene by infecting the cell. The viruses are modified so they can't cause disease when used in people.

Which of the following is a dihybrid cross?a. RrMM Rrmmb. RRMM rrmmc. RrMm RrMmd. rrMM RRmme. RrMm rrmm
Minchanka [31]

Answer:

c. RrMm x  RrMm

Explanation:

A dihybrid genotype is the one that is heterozygous for two genes. Hence, a dihybrid cross is a cross between two individuals that are hybrid for alleles of two different loci.

Among the given examples, the cross RrMm x RrMm is a dihybrid cross. Here, both given genotypes are heterozygous or hybrid for two loci (both genotypes have one dominant and one recessive allele for both the genes under study, R and r; M and m).

This cross explains the inheritance of two loci or two genetic traits. Hence, it is an example of dihybrid cross.

Amenorrhea may occur among women at fat levels as high as:
Sophie [7]
The correct answer is "16%"

16% of body fat in women is considered as low as normal body fat levels in women normally ranges from 22% to 25%. In cases of low body fat levels (i.e. in athletic women), there will be relative amenorrhea because of the suppression of the follicle-stimulating hormone and the luteinizing hormone leading to a type of amenorrhea called athletic amenorrhea.

The rate of a reaction catalyzed by an enzymes usually ________ with temperature; however, at temperatures above the optimum ran
oksano4ka [1.4K]

Answer:

increases; protein denaturation occurs

Explanation:

One of the characteristic of enzymes is the sensitivity to temperature .

Enzymes are sensitive to the changes in the environmental temperature.The enzymatic activities increases with increase in temperature,up to the optimum of 37 degrees in most animals.

However,once the optimum temperature has been exceeded,enzyme activities drops.This is because below optimum the rate of collision between the enzyme active sites and substrate molecules is very high,therefore more products are formed which increases the rate of reactions.

At temperature above the optimum,the high temperature  breaks the bonds,especially the hydrogen bonds holding the 3D structure of the active sites.Therefore,substrate molecules can not fit into the active site,and therefore enzymatic actives of the enzyme is affected,and the enzyme is said to be  denatured
