What is (are) the main difference(s) between passive transport and active transport? Group of answer choices Passive transport d

oes not require any cellular proteins; active transport requires cellular proteins. Active transport works against gravity (for example, upwards from the roots of a tree); passive transport works with gravity (downward). Passive transport occurs primarily in single-cell organisms; active transport occurs primarily in multi-cellular organisms. Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.

Answer:

Active transport requires cellular energy for substances to cross the cell membrane; passive transport does not.

Explanation:

Active Transport works against the concentration gradient and therefore needs energy to make it happen

Passive transport such as Diffusion and Osmosis uses the properties of natural movement of particles which moves the molecules from areas of high concentration to areas of low concentration or down the concentration gradient and happens passively without the need for energy

How does DNA homology measure genetic relatedness ?
lesya [120]

Answer:

by the nitrocellulose membrane filter method. (more info below)

Explanation:

Genetic relationship between mycoplasma as determined by nucleic acid homology.  DNA from each of the mycoplasma isolates tested was reacted separately by complementary RNA synthesized with homologous or heterologous DNA as a primer. The amount of DNA-RNA hybrids formed was tested using the method of the nitrocellulose membrane filter.

hope this helped!

Hershey and Chase used radioactive isotopes to label different parts of the phage. They grew one batch of phage in the presence
AlekseyPX

The sulphur would lable the capsule and the phosphorous the nucleic acid.

<h3><u>Explanation</u>:</h3>

Hershey and Chase experiment included growing of the pages in two batches, one in presence of 35S and other in presence of 32P. They then infected bacterial cells with these phages, cleaned them and then centrifuge the cells to isolate the marked elements in bacterial cells.

This was done to isolate which part of the phage is actually infective. Sulphur being a part of the proteins will mark the capsule whereas DNA having the phosphate bridges will be marked by 32P.

ladessa [460]

Answer:

The correct answer is option C.

Explanation:

Human subject research is an investigation or research that include human as the subject. In other words, An Investigator conducts clinical research on humans getting data through interaction and intervention of individuals.

investigator A has investigated biological specimens. These specimens are coded and linked to the identifiers. Investigator B's research using biospecimens human subject is not according to the human subject research in the federal regulations as investigator B did not get the individual identifiers.

Thus, the correct answer is option C.
