A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. When the rock is cut in half, what is the volume and d
spayn [35]

Answer:

Volume= 4 cm³

Density= 2 g/cm³

Explanation:

We have the following data:

volume= V= 8 cm³

mass= m= 16 g

The density is the mass per volume of a substance, so the density of the rock is:

density= d= 16 g/8 cm³= 2 g/cm³

When we cut the rock in half, we have a half volume and a half mass:

V= 8 cm³/2= 4 cm³

m= 16 g/2= 8 g

But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:

d = m/V= 8 g/4 cm³= 2 g/cm³

Light-headedness is a condition in which an individual may feel dizzy or about to faint and it often goes away or improves when one lies down. For the question above, you should respond by having your coworker sit down in a cool area, and drink plenty of cold water.

Anastasy [175]
I think, Lipogenesis is a common for organic molecules because the intermediate Acetyl-CoA is formed in most metabolic processes. Lipogenesis involves the formation of fatty acids from Acetyl-CoA. Acetyl-CoA is an intermediate stage in metabolism of simple sugars, such as glucose, which is the preferred source of energy for most living organisms.

Electron carrier molecules transfer electrons between metabolic pathways. Choose the electron carriers that transfer electrons f
denis23 [38]

Answer:

from glycolysis to electron transport.-glycolytic pathway

NADH  and FADH2 are the major electron carrier   from glycolysis through the Kreb Cycle to the electron transport chain.

Note-NADH  alone transports electron  from glycolysis  to the Kreb Cycle. while both   NADH and FADH2  transport electrons   from the kreb'cycle  to the electron transport chain.

from citric ac id cycle to the electron transport chain.

as explained above both NADH and FADH2.

The electrons are  in the hydrogen atoms, carried by these co-enzymes. When they reached the matrix, the hydrogen atoms are split into protons and electrons(p and e-). it is these electrons that form gradients which are transported as chains in the matrix. The gradients of the electron generated PMF for pumping Hydrogen atoms into the intramembrane of mitochondrial

Note.

Nicotinamide Adenine Di nucleotide Hydrogen(NADH)

Flavin Adenine Dinucleotide Hydrogen(FADH)
