They postulate, "We predict the plant grown in blue light to be higher when we compare the height of the one grown in blue light to that grown in green light.

Plants' vegetative growth is strongly influenced by light with a wavelength of 400–520 nm, which includes light violet, blue, and green. Far red/infrared light with a wavelength of 720–1000 nm is used for germination, however very little absorption happens in this wave band. Plants may do a variety of tasks with the aid of various coloured light. For instance, blue light aids in promoting vegetative leaf growth. Plants can blossom when exposed to red and blue light. Indoor plant growth thrives under cool fluorescent lighting.

Fertilization is the process through which animals and other living things reproduce and create zygotes. Based upon how the male and female gamete merge, they can be divided into internal and exterior fertilisation.

As a means of survival, animals that display external fertilisation frequently produce a lot of eggs. A lot of eggs can aid in boosting the reproduction rate because they can be damaged during external fertilisation.Fertilization is the process through which animals and other living things reproduce and create zygotes. Based upon how the male and female gamete merge, they can be divided into internal and exterior fertilisation.In internal fertilisation, the eggs are either grown in a secure reproductive canal or are protected when laid by a shell, a defence mechanism exhibited by animals like mammal, reptiles, and birds.

Answer: Non-falsifiable hypotheses: Hypotheses that are inherently impossible to falsify, either because of technical limitations or because of subjectivity. E.g. "Chocolate is always better than vanilla." [subjective].

A statement, hypothesis, or theory has falsifiability if it can be proven false by contradicting it with a basic statement or observation.

Hope this helps....... Stay safe and have a Merry Christmas!!!!!!!!!!!!!! :D

Explanation:

Answer:

A hypothesis is hard to be considered "falsified" because it is based on the knowledge that you have and you are making a presumption based on a set of data and then working to prove and backup the hypothesis which could potentially be wrong but isn't falisfied as it is your own conclusion an not a statement    

A condensed growth phase known as the second gap (growth) (G2) phase sees the replication or production of several organelles.  Thus, option A is correct.

A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.

Microtubules employed in the mitotic spindle as well as other components required for mitosis and cell division are produced during G2.

The G2 phase is the final stage of interphase. The cell has developed, its DNA has been copied, and it is now almost ready to divide. The focus of this final stage is preparing the cell for meiosis or mitosis.

Therefore, The cell must continue to expand and make any additional molecules necessary for division during G2.

Answer: Dialysis

Explanation: Dialysis involves either shunting the patient's blood through a special machine (haemodialysis) that helps remove the wastes while preserving water and salts, or removing wastes through fluid introduced into the abdomen (peritoneal dialysis).

Shunting the blood so that it may be filtered is known as Hemodialysis. It is a long answer. Hemodialysis is a process of removing waste and extra fluid from the blood.

Blood is filtered outside the body using a machine called a dialyzer, also known as an artificial kidney.The process of shunting blood for it to be filtered during hemodialysis is done through a vascular access, which is created by a minor surgery that connects an artery and vein, usually in the arm. The blood is pumped from the patient's bloodstream into the dialyzer, which filters the blood, and the filtered blood is returned to the patient's bloodstream.

Hemodialysis is used when the kidneys are unable to filter the blood on their own due to kidney failure. This may be caused by various factors, including diabetes, high blood pressure, glomerulonephritis, and other kidney diseases. Hemodialysis is usually done three times a week for three to five hours per session.

9985 is the lk of the resulting chromosome  .

Lk/ linking number is the topological property of DNA which is a is a sum of twists and writhes. When one strand of DNA turned around another strand is termed a twist while inter-coiling of the double helix is termed as writhe .For circular DNA/chromosome, the Lk remains zero or unchanged which is a sum of twists and writhes introduced is always equal to Lk. The linking number can be changed by breaking and rejoining of the strand using endonuclease enzyme like Topoisomerase. The Topoisomerase introduces a break in one or both DNA strands, after rotating the two DNA strands relative to each other, breaks in strand is filled by DNA ligase.  Type II topoisomerase enzymes cleave the dsDNA ultimately changing the linkage number and convert a single positive supercoil into a negative supercoil. This cleavage by type II topoisomerase leads to the reduction in linkage number by two (-2) in a single step.

As in given problem,

the Topoisomerase acts five times on the circular chromosome the Lk will decrease by 10.

Hence, the final Lk for given chromosome after Topoisomerase activity will be 9985.

Polygenic traits do not follow Mendelian inheritance patterns because multiple genes are involved.

Polygenic inheritance is a type of quantitative inheritance in which multiple independent genes have a similar or additive effect on a single quantitative trait. A polygene is a gene that, in conjunction with other genes, has a minor effect on phenotype. Because the effect of a single gene is so small, it is difficult to detect.

Multiple genes have the same effect. Each allele has an additive or cumulative effect. Polygenic inheritance differs from multiple alleles in that three or more alleles are present in the same locus, with any two alleles present in an organism, such as the ABO blood group system, which is controlled by three alleles. There is no epistasis, or masking of the expression of an allele from a different locus.

During prophase, the parent cell will have 48 chromatids. This is because during interphase, the DNA replicates, resulting in each chromosome consisting of two sister chromatids.

Therefore, if the parent cell has 24 chromosomes, it will have a total of 48 chromatids during prophase.

Regarding the major difference between plant cells and animal cells, the most accurate statement is: "Only plant cells have a cell wall." Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection to the cell. Animal cells, on the other hand, do not have a cell wall.

In the antisense technique, a modified strand of RNA or DNA binds with specific molecules of mRNA, thereby preventing the protein encoded by the mRNA from being produced.

Antisense technology is a genetic engineering technique that blocks the synthesis of the protein that causes the disease. It works by interrupting the transcription or translation of a specific gene, resulting in the production of fewer or no proteins. The antisense technology aims to stop the action of one or more genes by delivering synthetic molecules of the genetic material DNA or RNA to the cell.

The DNA or RNA molecules used are complementary to the target gene, meaning they match the target gene's sequence in reverse.The RNA or DNA molecules bind to the target mRNA, and then the cells in the body destroy them, preventing the protein from being produced. Thus, this technique prevents the production of specific proteins in the cell, and it is used as a method to treat certain diseases that are caused by the overproduction of specific proteins.
