Difference between the two, DNA and RNA, is that DNA comprises of deoxyribose sugar while RNA comprises of the <u>ribose sugar</u>.

Further Explanation:

DNA and RNA are known to be the most vital molecules in the field of cell biology and is responsible for storing as well as reading the genetic information which basically underpins all life. They are both known to be linear polymers comprising phosphates, sugars, and bases.

DNA or deoxyribonucleic acid and RNA or ribonucleic acid are basically polymers comprises of monomers which are called nucleotides. A molecule of RNA comprises of 5 carbon sugar-phosphate associated with one of the four nucleic acid bases, namely, cytosine, guanine, uracil, and adenine. RNA comprises of a ribose sugar, with the hydroxyl modifications. RNA comprises of only one strand and is also known to be shorter as compared to DNA molecule. As RNA comprises of a ribose sugar, it is known to be more reactive as compared to the molecule of DNA.  

In a molecule of DNA, the sugar is lacking the hydroxyl group at the 2’ position and the thymine base is observed instead of uracil. DNA comprises of two strands and it is arranged in a double-helical structure. DNA is considered to be more stable as compared to the RNA molecule due to which, it is useful for the DNA molecule to carry the responsibility for storing the genetic information safely.

I believe the correct answer is B. Deoxyribose

<h2>Explanation:</h2>

The nucleotide of a DNA is slightly different to that of RNA due to an addition of a hydroxyl (OH) on the sugar molecule on the RNA nucleotide located on position 2 of the nucleotide.

<h2>Further Explanation:</h2>

The DNA and RNA molecules are almost similar.

<h3>1. Nitrogenous bases</h3>

They both have a nitrogenous base on position one. The nitrogenous base can be one of the 5 bases Adenine, Cytosine, Guanine or Thymine which can be coded by their alternate Uracil in the right places. They are considered to be the building blocks of the DNA and RNA molecules.

<h3>2. Phosphate group</h3>

Located on position 5 of the nucleotide of both in RNA and DNA is the phosphate group. It has important functions including forming part of an ATP molecule to provide the body with the required energy. They also activate proteins through a process called phosphorilation for example in the cAMP cycle they activate protein kinases.

<h3>3. Ribose</h3>

On the second carbon position there is a ribose sugar. It has only one oxygen molecule linked to each one of the 5 carbon atoms. On the second carbon position, the oxygen molecule is bound to a hydrogen atom forming a hydroxyl (OH). It is only in the RNA that the ribose sugar exists giving it its name; Riboneucleic acid.

<h3>4. Deoxyribose</h3>

The prefix deoxy- means that lack of oxygen. That is where the name deoxyribonucleic acid (DNA) comes from. On the second carbon position of the nucleotide is where there is lack of the oxygen molecule that usually binds to the carbon and hydrogen molecules leaving a hydrogen only bound to the 2nd carbon position.  This sugar is only found in the DNA molecule. This small lack of an oxygen bound to the hydrogen allows specific enzymes to be able to identify the difference between a DNA molecule and an RNA molecule.

at short focusing distances, ciliary muscles contract. what effect do these contractions have on the suspensory ligaments?
True [87]

At short focusing distances, ciliary muscles contract causing the suspensory ligaments to tighten.

The ciliary muscle is an integral muscle of the eye that is constructed as a ring of smooth muscle in the middle layer of the eye, the uvea (vascular layer). It regulates the passage of aqueous humor into Schlemm's canal and governs accommodation for observing objects at different distances.

A suspensory ligament is a ligament that provides support to a body part, particularly an organ. The suspensory ligament protects the fetlock from hyperextension (i.e., falling too low) during exercise. The ligament begins in both the fore and hindlimbs at its connection to the back of the upper cannon bone.

When the ciliary muscle relaxes, its diameter increases; when the suspensory ligaments tighten, the lens becomes thinner. This occurs when concentrating on a celestial object. When the ciliary muscle contracts, the lens becomes much more circular and has more focusing power because the pressure on the zonular fibers is reduced. When the ciliary muscles relax, these fibers contract, pulling the lens out and creating a flatter shape with less focusing power

Steroid hormones exert their action by ________. A. entering the nucleus of a cell and initiating or altering the expression of
Blizzard [7]

Answer:

The correct option is A. Steroid hormones exert their action by entering the nucleus of a cell and initiating or altering the expression of a gene.

Explanation:

Steroid hormones are derived from cholesterol and regulate multiple biological processes. All steroid hormones exert their action by crossing the plasma membrane and by binding with their respective intracellular receptors. They stimulate cell growth in a very different way, their lipophilic nature gives them the ability to cross lipid barriers, so, without the need for extracellular signals, these hormones can easily enter the cell, cross the cytoplasm and reach the nucleus. There they bind to specific receptors that are associated with DNA promoter regions, modifying their structure and promoting the expression of the genes under their control.
