One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, w

hen placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+).
Thus, H2CO3 = HCO3- + H+
If the pH of the blood increases, one would expect:

(A) a decrease in the concentration of HCO3- and an increase in the concentration of H+

(B) an increase in the concentration of H2CO3 and a decrease in the concentration of HCO3-

(C) a decrease in the concentration of H2CO3 and an increase in the concentration of HCO3-

(D) an increase in the concentration of HCO3- and a decrease in the concentration of OH-

(E) a decrease in the concentration of HCO3- and an increase in the concentration of both H2CO3 and H+.

I'm not sure if it is C or D ​

Answer:

The answer is "Option C".

Explanation:

In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.  

  • The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood.
  • It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.

What would happen to the proton gradient and ATP production after a drug has poisoned the enzyme that combines acetyl CoA and ox
I am Lyosha [343]

Answer:

The best answer to the question: What would happen to the proton gradient and ATP production after a drug has poisoned the enzyme that combines acetyl CoA and oxaloacetate to form citrate? Would be, C: Less NADH production would create to a weaker proton gradient and less ATP production.

Explanation:

The reason comes from remembering that ATP is a molecule that is produced when protons are transferred in a chemical reaction called anabolism to the precursor for ATP, ADP. This process of transference of protons requires the correct work of several chemical compounds, including enzymes and coenzymes, which basically assist enzymes in the management of hydrogen atoms during metabolic processses.

NADH, like others, is a coenzyme whose task is to accept hydrogen atoms and assist in the oxidation-reduction reactions that take place in the body, including the production of ATP. If a poison has stopped the correct transfer of protons by preventing the correct work of both enzymes and coenzymes, then the direct result is the lesser production of NADH and therefore there will be a much less efficient process of proton transfer to produce ATP.

In a certain species of rabbits, black coat color is dominant over brown coat color. What is the probability of producing a rabb
kenny6666 [7]

Answer:

2) 25%

Explanation:

Let the traits for the black coat color be = BB

Let the traits for the brown coat color be = bb

Let the traits for heterozygous black coat color be = Bb

Now; the question says what is the probability of producing a rabbit with brown coat color from two rabbits that are both heterozygous for black coat color.

This implies that if two rabbits that are both heterozygous for black coat color cross together;

i.e  Bb × Bb ;

The offspring will be (BB, Bb, Bb, bb)

BB (rabbits with black coat color) = 1/4

Bb (rabbits that are heterozygous for black coat color) = 2/4

bb (rabbit with brown coat color) = 1/4

Lets focus on ''bb'' ;

bb = 1/4 × 100%

= 25%

Give one example of a parasitic fungi and explain how it affects human health.
Zarrin [17]

Answer: Many pathogenic fungi are parasitic in humans and are known to cause diseases of humans and other animals. In humans, parasitic fungi most commonly enter the body through a wound in the epidermis (skin). Such wounds may be insect punctures or accidentally inflicted scratches, cuts, or bruises. One example of a fungus that causes disease in humans is Claviceps purpurea, the cause of ergotism (also known as St. Anthony’s fire), a disease that was prevalent in northern Europe in the Middle Ages, particularly in regions of high rye-bread consumption. The wind carries the fungal spores of ergot to the flowers of the rye, where the spores germinate, infect and destroy the ovaries of the plant, and replace them with masses of microscopic threads cemented together into a hard fungal structure shaped like a rye kernel but considerably larger and darker. This structure, called an ergot, contains a number of poisonous organic compounds called alkaloids. A mature head of rye may carry several ergots in addition to noninfected kernels. When the grain is harvested, much of the ergot falls to the ground, but some remains on the plants and is mixed with the grain. Although modern grain-cleaning and milling methods have practically eliminated the disease, the contaminated flour may end up in bread and other food products if the ergot is not removed before milling. In addition, the ergot that falls to the ground may be consumed by cattle turned out to graze in rye fields after harvest. Cattle that consume enough ergot may suffer abortion of fetuses or death. In the spring, when the rye is in bloom, the ergot remaining on the ground produces tiny, black, mushroom-shaped bodies that expel large numbers of spores, thus starting a new series of infections.

When two hormones must be present to achieve full expression of an effect, that interaction is called ______________.
Vinvika [58]

Answer:

Synergism

Explanation:

Synergism means cooperation, and is a term of Greek origin (synergy). Synergy is a work or effort to accomplish a certain very complex task, and to be able to succeed in the end. Synergy is the moment when the whole is greater than the sum of its parts.

In physiology, synergism occurs when the effect of two or more combined chemical agents is greater than the sum of individual effects. Concerning hormones, synergism happens when two hormones must be present for the full expression of an effect. That is, two hormones act for a certain purpose.

Example: FSH (follicle stimulating hormone) and estrogen cause oocyte maturation, but this only occurs if neither acts in isolation.
