I think that isn’t B but you don’t have to believe me
<span>In order to determine the sugar molecule associated with the nucleic acid, we must first determine if the nucleic acid is a deoxyribose nucleic acid (DNA) molecule or a ribonucleic acid (RNA) molecule. We can determine this by looking at the bases in the molecule, as DNA has thymine and RNA has uracil. After the type of molecule is determined, the nature of the sugar is given by the name. DNA has deoxyribose and RNA has ribose</span>
The female should be gently wrapped with dry blankets due to exposure of temperature of about 25 degrees Fahrenheit.
Explanation:
Prolonged exposure to extreme heat or cold conditions can impair the body’s temperature control system.
In the above case the patient is exposed to extreme cold condition in a wood with a freezing temperature of 25 degrees Fahrenheit (-3 degrees Celsius) which leads to hypothermia and frostbite.
Extreme cold conditions can freeze the tissue layers of the parts of the skin exposed like those of the face, hands and feet especially. Due to this the skin becomes white (even grayish yellow or blue) and waxy, cold and numb, and the outer surface may become hard and blistered. There will also be extreme pain, stinging and tingling sensation in the exposed areas.
These changes are mainly due to impaired blood circulation and hypothermia. Hypothermia which is lowering of body temperature causes confusion and lethargy.
The first-aid given for frostbite primarily includes warming the body. The affected person’s body should be covered with warm and dry blankets gently and loosely and any wet clothes should be removed.
So when the body is warmed, the body temperature also will increase and correct the hypothermic symptoms like lethargy and confusion.
Nucleosomes are composed of "histones" class of molecules.
<u>Explanation:</u>
Histones usually presented in eukaryotic nuclei of cells which seemed as strong level of proteins that bundle and organize DNA into structural groups called nucleosomes in biological science.
They are chromatin's chief protein elements, functioning as spools along which DNA spins, and playing a major role in regulating genes. Five forms of histones have been recognized:
- H1 (or H5), H2A, H2B, H3, and H4;
- H2A, H2B, H3, and H4 are the main histones and H1 and H5 are the linker histones.
