Answer:
This method involves making observations, forming questions, making hypotheses, doing an experiment, analyzing the data, and forming a conclusion.
Explanation:
The scientific method has five basic steps, plus one feedback step:
1.Make an observation.
2.Ask a question.
3.Form a hypothesis, or testable explanation.
4.Make a prediction based on the hypothesis.
5.Test the prediction.
6.Iterate: use the results to make new hypotheses or predictions.
Answer:
A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.
well hope this help at least (good night)
Answer:
Marker proteins are proteins that are incorporated in the cell membrane of a cell and based on these marker proteins a cell is identified. These proteins are very important while considering an organ transplant. If the marker proteins of the donor organ are not similar to the marker proteins of the original organ of the patient, then the immune cells will recognize the organ as foreign and the transplant will be rejected.
Answer:
The correct answer is option c). "Defective enzymes result in the accumulation of potentially toxic substances".
Explanation:
Lysosomal storage diseases (LSDs) are a group of rare metabolic disorders that have a genetic influence and are, most of time, autosomal recessively inherited. The molecular basis of the diseases are an accumulation of potentially toxic substances due to the presence of defective enzymes. In fact, LSDs are often triggered by a single defective enzyme that is required for lipids metabolism.
