Answer:
Density = mass/volume = 57g/4.2 mL ≈ 13.6 g/mL
Explanation:
Mass = 57 g Volume = 4.2 mL
The density of mercury is ⇒ 13.6 g/cm3.
Trust me I got it wrong and it gave me this. I just did the instruction.
There numerous of them but some of them would be contaminated soil which can be followed with altered soil chemistry that contains fewer soil organisms that are essential. The third one would be surface runoff due to extensively modified hydrology of the area.
Answer:
Answer is A. Cdk7 of the CAK (TFIIH component) phosphorylates Cyclin 8 of the Mediator to down regulate promoter activity.
Refer below.
Explanation:
Cdk7 of the CAK (TFIIH component) phosphorylates Cyclin 8 of the Mediator to down regulate promoter activity is a FALSE STATEMENT.
Answer: Substances that are protein based cannot cross the lipid cell membrane, but can exert their effect by binding to the proteins based receptors present on the lipid bilayer.
Explanation:
Hormones such as calcitonin , Parathyroid hormone and pituatry horomones are proteins and water soluble.They cannot cross lipid bilayer but can bind to ligand binding protein receptors.
These receptors are protein macromolecules that are specific in nature for specific hormones.
After binding to the receptors, these hormone-recpetor complexes activate second messengers and regulate the downstream effects.
