polymerase Chain Reaction PCR is your answer 100%
The process of Polymerase chain reaction (PCR) is given in the given diagram. The correct option is C.
What is polymerase chain reaction?Polymerase chain reaction (PCR) is a laboratory technique for rapidly producing (amplifying) millions to billions of copies of a specific segment of DNA, which can then be studied further.
PCR is also useful in a variety of laboratory and clinical techniques, such as DNA fingerprinting, bacteria or virus detection (particularly AIDS), and genetic disorder diagnosis.
The DNA produced by PCR, once amplified, can be used in a variety of laboratory procedures.
Polymerase chain reaction (PCR) is a technology that uses enzymatic replication of nucleic acids to quickly and easily amplify DNA sequences.
This method is indispensable in the field of molecular biology and is one of the fundamental methods for DNA analysis.
Thus, the answer is C.

From Earth, Star Y appears to be the brightest while Star X and Star Z appear to be similar in brightness. Which list orders the stars from closest to farthest from Earth?
Star X Star Y, Star Z
Star X, Star Z. Star Y
Star Y. Star X, Star Z
Star Y, Star Z, Star X
Answers
Answer:A
Explanation:
The order of stars from closest to farthest from Earth is as follows:
Star Y, Star Z, Star X.Thus, the correct option for this question is D.
What is Star?Star may be characterized as a huge ball of blazing gases in space that is typically observed from the earth as a point of light in the sky at night. It is a type of astronomical object.
As we relate the brightness of a star with respect to the distance, it is found that the closer a star is, the brighter it will appear in the sky. So, a Star Y is the brightest, it will closer to the earth. With this sense of knowledge, options 1 and 2 are eliminated.
Star X is larger than star Z, so, star Z is found to be closer than Star X. With this, option 3 is also eliminated.

Why does a fever become dangerous to body functions if it continues to rise?
A. Dehydration will occur
B. Osmosis may be affected due to lack of water
C. A fever breaking is more dangerous than the fever itself
D. Proteins become denatured and are unable to complete their jobs
Answers
b osmosis may be affected due to lack of water
Fever has been defined as the rise in the temperature of the body. The rise in fever is a dangerous process as lack of water causes dehydration in the body. Thus, option A is correct.
What is dehydration?Dehydration is the loss of water and body fluid than the intake of the fluid amount. The high-temperature condition of the body causes the loss of water from the body that gets evaporated from the skin cells.
When a person is suffering from fever the body fluid and electrolytes are lost by vomiting, tears, sweat, diarrhea, and urine. Dehydration can be detected by thirst, dry mouth, dizziness, etc.
Too much heat in the body during fevers results in the loss of water from the body that is more because the fluid intake gets reduced and the body becomes deficient in electrolytes and fluids.
It is a serious problem that should be dealt with so that the cells and tissues of the body can restore the water balance that is crucial for various activities and functions.
Therefore, option A. increase in the temperature in fever causes dehydration.

Answers
Answer:
RR is hom0zygous dominant and will Red
Rr is heterosygous and will also be red
rr is hom0zygous recessive and will be white
Explanation:
The filling of the chart with respect to the genotype given is as follows:
RR (homozygous dominant) gives Red eye color in fruit flies. Rr (heterozygous) will also deliver red eye color in fruit flies.rr (homozygous recessive) gives white eye color in fruit flies. What is meant by Genotype?Genotype may be defined as the ultimate combination of alleles of those genes which are selected for specific study in order to deliver some sort of genetic information.
As it is an organism is its complete set of genetic material. These can also be utilized in order to refer to the alleles or variants an individual carries in a particular gene or genetic location.
In fruit flies, red eye color is dominant over white eye color. So, when red eyed-colored (RR) flies are crossed with white-eyed colored flies (rr), they produce offspring with the genotype Rr and phenotype of red-eye color. This all deals with the law of dominance.
Therefore, the filling of the chart with respect to the genotype given is well described above.

To absorb water to lowers the intensity of flood.
Explanation:
The main role of certain plant cells in flood control is to absorb water as well as the decrease the flow of water which slower down the intensity of flood. There are some plants in which their cells absorb huge amount of water which decreases the amount of water in the flood and as a result flood water decreases so that's why vegetation is very important in order to avoid flooded condition.

What happens after activation of T cells
Answers
Answer:
Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
Explanation:
Helper T cells become activated when they are presented with peptide antigens by MHC class II molecules, which are expressed on the surface of antigen-presenting cells (APCs). Once activated, they divide rapidly and secrete cytokines that regulate or assist the immune response.
