Answer: The question is incomplete.

The options are not given but the correct answer is;

They can protect the body from infection.

Explanation:

Microorganisms are microscopic organisms that are found in every environment. They include bacteria, fungi, viruses e.t.c.

The can be single celled or form colony.

Microbes are of utmost important in larger animals in that they form symbiotic relationship with them. Microbes live in or on organisms.

Microbes help in digestion of food in intestinal gut and also help prevent infections due to their activities in or on the larger animals. Their secretions help to prevent Invaders. They benefit by having shelter and nutrients they feed on from their host.

Which of the following is not a reason we become shorter as we age?
Lady_Fox [76]

Answer:

The correct answer is - As a person ages, scoliosis may develop resulting in an abnormal spinal curvature and shorter stature.

Explanation:

Scoliosis is a condition in which spine curvature towards the sides takes place before the puberty during growth period or spurt normally. The cause of this condition could be muscle dystrophy or palsy and similar condition.

This affects the stature of an individual but not affected by age as it remains constant normally after development or growth till puberty. All other conditions are associated with the short stature and influenced by the age.

DNA replication is the process of doubling a DNA double chain. In cells, DNA replication occurs before cell division. Prokaryotes continually replicate DNA. In eukaryotes, the timing of DNA replication is highly regulated, ie in the S phase of the cell cycle, before mitosis or meiosis I. The multiplication utilizes the DNA polymerase enzyme which helps form bonds between the nucleotides that make up the DNA polymer. The process of DNA replication can also be carried out in vitro in a process called a polymerase chain reaction (PCR).

<h2>Further Explanation </h2>

A slow strand (Lagging strand) is a DNA strand located on the opposite side of the leading strand on the replication fork. These strands are synthesized in segments called Okazaki fragments. In this string, primases form RNA primers. The DNA polymerase can thus use OH 3 'free groups in the RNA primer to synthesize DNA in the direction of 5' → 3 '. The primary RNA fragments are then removed (for example by RNase H and DNA Polymerase I) and new deoxyribonucleotides are added to fill the gaps that were previously occupied by RNA. DNA ligase then connects the Okazaki fragments so that the synthesis of lagging strands is complete.

Primers both on the steering strand and on the lagging strand will elongate with the help of Holoenzyme DNA polymerase III. This multisubunit complex is a dimer, half will work on the steering strand and the other half will work on lagging strands. Thus, the synthesis of the two strands will run at the same speed.

Each dimer part of the two strands consists of subunit a, which has the actual polymerase function, and subunit e, which has an editing function in the form of exonuclease 3'– 5 ’. In addition, there is a subunit b that attaches polymerase to DNA.

Once the primers in the remaining strand are removed by DNA polymerase III, they will be removed immediately and the gaps caused by the loss of the primer are filled with DNA polymerase I, which has 5 '- 3' polymerase activity, 5 '- 3' exonuclease, and editing 3 exonuclease '- 5'. Eksonuklease 5 '- 3' discard the primer, while the polymerase will fill the gap caused. Finally, the Okazaki fragments will be united by the DNA ligase enzyme. In vivo, the dimoenzyme DNA polymerase III and primosomes are believed to form large complexes called replisomes. With the replisom DNA synthesis will take place at 900 bp per second.

Food moves from the mouth to the stomach through a long tube called the trachea. True False
8_murik_8 [283]
This is false. The tube that leads from the mouth to the stomach is called the esophagus. The trachaea leads from the mouth to the lungs, and is used in respiration, not digestion.
Hope that helped! =)
