How does the injection of insulin affect the signal transduction pathway of type 1 diabetics? a. Injected insulin prevents the glucose from binding to cellular protein receptor.
b. Insulin acts as a secondary messenger that cascades the message to allow glucose into the cell.
c. Insulin is absorbed into the cytoplasm and binds with the transcription factor to make it active.
d. Protein receptors on the cell bond to the insulin, which allows glucose to enter the cell.

The correct answer is D.

Explanation:

To act on target cells, insulin binds to a specialized protein that is located on the membrane of your target cells: the insulin receptor. When insulin binds to the receptor, it activates a cascade of signals within the cell (a process called signal transduction), which is essential for insulin to have an effect on its target tissues. Insulin increases the entry of glucose into cells and causes the number of certain proteins specialized in glucose transport to increase in the membrane of their target cells, such as adipocytes (adipose tissue cells) and skeletal muscle cells.

The correct answer is B, b. Insulin acts as a secondary messenger that cascades the message to allow glucose into the cell.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
