Answer:
The answers are :
Explanation:
A. Hidrolyisis- deficient RAS mutant :1. Continual activation of the MAP kinase pathway even in the abscence of signaling molecule, 5.Change in the expression of genes in the absence of the appropriate signaling molecule
C. High GDP affinity RAS mutant: 2.Failure to activate MAP kinase pathway following ligand binding to receptor kinase, 6. Target genes are not expressed even in the presence of signaling molecule
B. Neither: 3. Failure of receptor kinase to dimerize in the presence of ligand, 10. A continuously activated receptor in the absence of ligand
Answer: Option D
Explanation:
Apolipoprotein B is a type of apolipoprotein that bind lipids including cholesterol and forming the main organizing protein in lipoproteins such as in the low density lipoprotein. The low density lipoprotein serves as a vehicle to transport cholesterol into the cell through the receptor mediated endocytosis process. This process allows for the movement of larger molecules from the outside of the cell into the cell. Thus apolipoprotein can bind as ligands to the LDL receptors and allow for the transport of fats into the cell..
Hi,
Answer: A. The air around us
<u>My work:</u> The atmosphere holds up to 78.09 % of air. The atmosphere is also used up of 0.93 of Argon, 20.95% of nitrogen, and 0.04 % of carbon dioxide.
I Hope I Helped!
