Answer:

The correct answer will be-

1. Solar energy

2. Chemical energy

Explanation:

Photosynthesis is a complex process which takes place in green plants and algae. The process produces glucose molecule which is used by the plants to synthesise the energy molecules in the form of ATP and in the synthesis of other molecules.

The photosynthesis metabolic reactions synthesise glucose molecules using the carbon dioxide and water taking place in the presence of sunlight. Thus, the reaction converts the solar energy from the sun to the chemical energy stored in the bonds of glucose.

Thus,  Solar energy and Chemical energy are the correct answers.

In addition to E. coli, a risk factor for development of pyelonephritis is: a. urinary retention and reflux. b. nephrotic syndro
monitta

Answer:

One of the factors for the development of pyelonephritis, in addition to E. coli, is urinary retention and reflux (option a).

Explanation:

Pyelonephritis is an infection of the upper urinary tract caused by bacteria in the urine, such as Escherichia coli.

Under normal conditions, urine in the urinary bladder is aseptic, that is, without bacteria.  The presence of bacteria in the urine indicates a urinary infection.

Urinary retention is the limitation of the expulsion of urine from the bladder. This promotes:

  • <em>An increase in the amount of bacteria present in the bladder. </em>
  • <em>The pressure generated by urine retention causes the bladder to generate a retrograde flow - reflow - towards the ureters, leading the bacteria to the kidneys. </em>

The result of urinary retention and reflux - when bacteria are present - is an infection in the upper urinary tract, called pyelonephritis.

When DNA is compacted by histones into 10-nm and 30-nm fibers, the DNA is unable to interact with proteins required for gene exp
poizon [28]

Answer:

This is through the process of methylation and phosphorylation of histones tails.

Explanation:

The addition of   a methyl group  to the amino acid of the histones of the  nucleosomes   that compacted DNA  in the nucleus is  called mehtylation, while the addtion of phodpahte is phosphorylation

Its  effects  on  gene expression depends on the number of <u> methyl groups, and type of amino acid that  methylated. During transcription. </u>

<u />

The DNA double strands are compacted and therefore  hidden  from transcription factors and enzymes of transcription by the hitones  tails of the neuclosomes, Methylation  weaken the binding bonds between the tails and DNA structure ; thereby aiding the uncoiling of DNA  from the  tails.(nucleosomes).This chemical  reaction  aided  DNA  strands  exposure   to transcription factors and enzymes, for initiation of transcription. This explains the dyanmic activity of methylation

Futhermore phophorylation also favours unwrapping of DNA, by imitating   modifying enzymes e.g H3Y41E and H3T45E  and convert it to→→ H3Y41phopspahte to aid DNA unwrapping and accessibility to  transcription factors and RNA polymerase Enzymes,
