In samples of DNA isolated from two unidentified species in bacteria, X and Y adenine makes up 32% and 17%, respectively, of the
Vikki [24]

Answer:

On the basis of Chargaff's rule, in a double-helical DNA, A = T and G = C (Here A means adenine, T means thymine, G means guanine, and C means cytosine. For X, A is given 32%, therefore, T must be 32%, and the leftover 36% is to be distributed equally between G and C. Thus, G = C = 18% each.  

The assumption formed is that the DNA is a double-stranded structure. The species that exhibits higher G + C content in the molecule of a DNA is steadier at higher temperatures as it melts at high temperature. The species Y, which exhibits G + C in total as 66% is the thermophilic bacterium between the two.

Alisiya [41]

Answer:

Fever c) is regulated by chemicals that reset the body's thermostat to a higher setting

Explanation:

Fever is a high body temperature and is one of the ways our immune system attempts to combat an infection. It is also referred to as pyrexia and it could be more than between 37.2 and 38.3 °C (99.0 and 100.9 °F) in humans, there is not a single agreed-upon upper limit. <em>Temperature is regulated in the hypothalamus.</em> Fever helps your immune system fight infections by speeding up the functioning of cells and it makes it harder for bacteria and viruses to thrive in the body.

Just by looking at the color of a freshly drawn blood sample, how could you distinguish between blood that is well oxygenated an
Wittaler [7]

Answer:

Explanation:

There are two types of blood that flows through our bodies: oxygenated and deoxygenated. Oxygenated blood is the one that is pumped in the left side of the atrium in the heart. As its name tells us, is the one that is highly with oxygen and low in carbon dioxide. Normally a sample of an oxygenated blood will be very bright in red due to the amount of blood cells in it. Deoxygenated blood is the one that is pumped in the right side of the atrium in the heart. This blood is the one that is low in oxygen and high in carbon dioxide. It is also known as the venous blood. Normally a sample of a deoxygenated blood will be darker almost going on blue.

PLEASE HELP ASAP IN A RUSH!!!!What do osmosis and diffusion have in common? A. Both are the net movement of randomly moving mole
NARA [144]

The right answer is A.

Osmosis is a phenomenon that considers only the exchanges between two liquid solutions of different concentrations in liquid phases separated by a semi-permeable wall. Osmosis is a phenomenon of diffusion of matter, demonstrated when solvent molecules pass through a semi-permeable membrane separating two solutions whose solute concentrations are different; the overall transfer of solvent is then from the least concentrated solution (hypotonic medium) to the most concentrated solution (hypertonic medium) to equilibrium (isotonic media).

The diffusion of matter, or chemical diffusion, refers to the natural tendency of a system to render uniform the chemical potential of each of the chemical species it contains.

Chemical diffusion is an irreversible transport phenomenon that tends to homogenize the composition of the medium.
