Answer:

no2

Explanation:

beacuse when people number growth too much it can have impact by economic and etc and many people are hunting animals for food and for other thing so we have to balance it

garik1379 [7]

Answer:

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.

Explanation:

In general the concentration of sodium ion is higher outside the cell in the extracellular fluid and the concentration of potassium ion is higher inside the cell.

During an active transport, a cell uses energy to move molecules against the gradient as a part of primary active transport. In the secondary active transport, the molecules move as per the electrochemical gradient established by the primary active transport.

In primary active transport, sodium ion moves out of the cell and potassium ion moves into the cell through the assistance of sodium potassium pump. In order to maintain the stability, calcium ion from the sarcoplasmic reticulum is pumped out of the cell

Hence , the correct answers are

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.

Answer:

a. combine the samples and check for coagulation

Explanation:

a. combine the samples and check for coagulation

We know that hemophilia is X linked recessive disorder which arises basically due to lacking of clotting factor in the blood (Factor VIII or Factor IX). According to the condition provided if pathology is closed so doctor can not perform the specific test so only their is chance to combine the sample of patient blood with the classic hemophiliac blood sample.As here doctor is sure that the blood sample available in his hospital is of hemophiliac patients so it does not contain clotting factor. When he mix both blood and then if the blood show coagulation it means David do not have hemophilia but if after mixing both the blood sample coagulation will not occur so David may be hemophilic.

ITS DUE TODAY PLEASEEE

BartSMP [9]

Answer:

The correct answer is option A) "The plasmid would not contain the human gene because the cuts are not compatible".

Explanation:

One of the basis of genetic engineering is to use the proper restriction enzymes to cut fragments of DNA. After cutting DNA with restriction enzymes most of the time the fragments have sticky ends, which are a few nucleotides that are one stranded and complementary to each other. Scientists take advantage of this characteristic and use the same restriction enzyme to cut genes and plasmid and later put it together with DNA ligases. If genes and plasmids are accidentally cut with different restriction enzyme it is very likely that the plasmid would not contain the human gene because the cuts are not compatible, since no sticky ends are generated.
