All what the word tetravalent means is that carbon can form 4 chemical bonds, due to the fact that carbon has 4 unpaired valence electrons in its furthest shell, which can be used to bond to other atoms, to form linear and cyclic structures in organic compounds.
Tetravalent also tells us indirectly what the molecular geometry of the atom would be if bonded to those number of bonds, if 4, then it would be tetrahedral and have bond angles of 109.5.
Water molecules ,some ions ,non polar compounds and glucose can pass through a cell membrane
Answer:
The pituitary gland also produces hormones for organs in the body, as well. It creates:
Oxytocin for the uterus and mammary glands to stimulate contractions that aid in birth and milk production

<span>If a human has not eaten in 6 days,
o Would blood glucose levels be high or low?
The answer is simple, your glucose will be dangerously high.
o </span><span>Would ketones be in the blood?
Yes, yes they would.
</span><span>o Would glucagon levels in the blood be high or low?
I am not exactly sure about this, but I know that when you haven't eaten </span><span>your body prevents your blood sugar from getting too low by releasing glucagon levels. So I assume it'd be high?
That's all I can answer, Hope this helped
