Forming a hypothesis is the first step of the scientific method.

Biology
1 answer:
exis [7]3 years ago
4 0

Answer:

The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.

Explanation:

The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables

iVinArrow [24]

Answer: Option C

Explanation:

Color blindness is a common hereditary condition which means it usually passes from parents. Red green color blindness is passed on from the mother to the son.

The chromosome number 23 is the sex chromosome also responsible for colorblindness. As it is sex linked the son can receive the recessive allele from the mother.

The mother of the child had a recessive allele which she transferred into her son. As it is sex inherited disease the son is affected by gene carried from mother.

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.

Rotenone, a toxic compound isolated from plants, strongly inhibits the transfer of electrons from iron-sulfur centers in Complex
Darya [45]

Answer:

(A) It prevents electron flow from the iron-sulfur centers in complex 1 to the ubiquinone. Due to reduction in electron transfer rate, there is a decrease in the production of ATP which is dangerous for some insects and fish over time.

(B) It also prevents electron flow from cytochrome b to cytochrome c1 at the complex III which leads to QH2 accumulation. If oxidized Q is not present, these is alteration of electron flow and the production of ATP is altered.

(C) Rotenone only prevent electron transfer into the chain at Complex 1  but it does not affect electron transfer at Complex II. Although there is slow ETC, it does not stop completely. However, Antimycin A prevents the oxidation of QH2, the final electron acceptor crom complex I and complex II. Thereby, stopping the production of both ETC and ATP. It can be concluded that antimycin A is a more potent poison.

Explanation:

Rotenone prevents electron flow from the iron-sulfur centers in complex 1 to the ubiquinone. Due to a reduction in electron transfer rate, there is a decrease in the production of ATP which is dangerous for some insects and fish over time. Antimycin A also prevents electron flow from cytochrome b to cytochrome c1 at the complex III which leads to QH2 accumulation. If oxidized Q is not present, there is an alteration of electron flow and the production of ATP is altered. Antimycin A is more potent than rotenone.
