If a plant were to absorb a substance that readily reacts with carbon dioxide in the stroma, the dark reactions would be most li
Assoli18 [71]
The right answer is the dark reaction would stop happening.
The Calvin cycle (or dark reactions, independent of the sunlight) makes it possible to manufacture glucose, an energy molecule, from carbon dioxide. This is called carbon fixation.There are three reactions of this cycle take place in the stroma of chloroplasts: the first of which is the fixation of carbon dioxide. which is a limiting step in this cycle.If a substance other than the components of the dark reactions absorbs and uses carbon dioxide, the carbon cycle will not be able to occur for lack of one of these ingredients which is the CO2.

Animals with a three-chambered heart would include:_______
Setler79 [48]

Animals with a three-chambered heart would include Amphibians.

  • Amphibians have three-chambered which comprises of two Atria and one ventricle. Examples of Amphibians include Frog, Toads, Salamanders.
  • In Amphibians heart blood from the single ventricle travels to the lungs, skin, and body, where it is oxygenated. Before being pumped out of the heart, deoxygenated and oxygenated blood are mixed in the ventricle.
  • This is because the Amphibians have low rate of metabolism and thus requires less oxygen for their metabolism.
  • As a result heart's load to deliver oxygenated blood to body is lowered.

Thus, from the above pointers we can conclude that only Amphibians from the option have three-chambered heart.

Pregnancy, which is characteristically associated with changes in hormone levels in the body is a process tightly regulated by:
Blababa [14]

Answer:

Pregnancy, which is characteristically associated with changes in hormone levels in the body is a process tightly regulated by the hormon Human Chorionic Gonadotropin

Explanation:

The so-called pregnancy hormone is the Human Chorionic Gonadotropin (HCG). It only occurs during the gestation period and is responsible for regulating the entire process. Segregated by the placenta, it can be found in urine and blood.

The presence of the hormone in the urine allows to confirm the pregnancy with the test.   As in pregnancy, the placenta begins to form, the cells that make it up begin to stimulate the production of HCG, which causes the hormone levels to increase very rapidly in the first trimester of pregnancy
