Answer:

D. Chemoautotrophs

Explanation:

Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.

Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.

Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.

Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.

Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.

Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.

Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.

After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?
Brilliant_brown [7]

Answer:

(D) Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

Explanation:

As Frida was exercising, her muscle cells were undergoing a frantic pace of metabolism (contraction and relaxation), where oxygen supply did not supply the required effort, thus causing muscle fatigue and heavy breathing.

Physical activity is synonymous with moving muscles. The more muscle fibers strive to accomplish a task, the more they consume the oxygen brought into the bloodstream. When this occurs, the body begins to breathe hard as lactate is transported to the liver.

This forces the lungs to work at a fast pace, as they are responsible for oxygenation. The heart also speeds up because it needs to pump blood more vigorously. This is why during exercise the heart rate and breathing rate increase and we breathe heavily.

kramer

When a person has linked a neutral stimulus and an unconditioned stimulus so that now the neutral stimulus triggers the conditioned response, <u>acquisition</u> has occurred.

<u>Explanation:</u>

A trigger that in the beginning causes no specific answer other than attention concentration is understood as "a neutral stimulus". In operant conditioning the neutral stimulus becomes a conditioned stimulus when used in combined way with an unconditioned stimulus.

Now let us say, for instance, you need to take your child to the pediatrician for a shot. The pediatrist hits a buzzer before the shot to call her nurse to come in and help her conduct the vaccine. Here the buzzer's noise is the neutral stimulus, as it generates no reaction from the infant, but the child knows that.
