Answer:
The t-test
Explanation:
<em>The researcher should use a t-test to compare the two means and check if they are significantly different from each other.</em>
In using the t-test, both null (H0) and alternate (H1) hypothesis are made such that:
Thereafter, the value of t is calculated and compared to its critical value on the table. The formula for calculating the t goes thus:
where, Y1 = mean of population 1, Y2 = mean of population 2, S1 = variance of population 1, S2 = variance of population 2, n1 = number of individuals in population 1 and s2 = number of individuals in population 2.
<em>At the end of the day, if the calculated t value is more than the critical value of t, the H0 is rejected and it shows that the two means are significantly different. Otherwise, the H0 is accepted and this shows that there is not significant difference between the mean of population 1 and that of 2.</em>
Answer:
C shrink
Explanation:
a hypertonic solution has more solutes than the intracellular environment, so water will leave the cell to try to achieve equilibrium. If enough water is lost, the cell will take on a wrinkled or shriveled appearance. In red blood cells this is called crenation and the surface of the cells take on a scalloped appearance. A high amount of water loss can be damaging or even fatal for a cell.
Answer:
The correct answer is Multiple myeloma.
Explanation:
Multiple myeloma is a type of bone marrow cancer caused by a malignant degeneration of plasma cells. Normal plasma cells are part of the immune or immune system, responsible for dealing with infections and diseases of external origin. Plasma cells are normally found in the bone marrow, mixed with other cells of the immune system and with the cell-producing cells of the blood. When there is an infection, the B lymphocytes respond, become plasma cells or plasma cells and produce antibodies (also called immunoglobulins) that help the body fight infection. T lymphocytes respond with various transformations that allow them to directly attack infectious agents or help other types of cells defend the body.
Answer:
The cell membrane is decribe by sandwich model and by fluid mosaic model.
Explanation:fluid mosaic model is used to describe the kinds of protein which are present in cell or plasma membrane ...according to this the cell membrane contain intransic,extrinsic,and conjugate molecule like glycoprotien,glycolipid etc.
