Given:
m = 12 g, the mass of the cylinder
r = 2 cm, the radius of the cylinder
h = 6 cm, the height of the cylinder.
Calculate the volume, V, of the cylinder.
V = πr²h
= π*(2 cm)²*(6 cm)
= 75.398 cm³
By definition,
density = mass/volume.
Therefore,
density = m/V
= (12 g)/(75.398 cm³)
= 0.159 g/cm³
= 0.16 g/cm³ (nearest hundredth)
Answer: 0.16 g/cm³
This means that we are virtually certain to share a common ancestor at some point in our evolutionary history. Although this 2 percent difference can manifest itself as huge phenotypical differences between species (such as between humans and chimpanzees), it indicates that our species diverged relatively recently on the evolutionary timeline.
Answer:
Glutamic acid
Explanation:
Reductive amination is a form of amination that involves the conversion of a carbonyl group to an amine via an intermediate imine. The carbonyl group is most commonly a ketone or an aldehyde. In this reaction, in the presence of enzyme glutamate dehydrogenase, ammonium ion directly combines with alpha-ketoglutaric acid, to form glutamic acid (amino acid) and for this to happen, a reduced coenzyme (NADPH) is required.
The biosynthesis of glutamic acid can be obtianed from the reductive amination of γ-ketoglutaric acid
γ-Ketoglutaric acid is a common precursor in synthesis of glutamic acid. Addition of NADPH and ammonia or alpha amino acid with γ-Ketoglutaric acid produces glutamic acid. Enzymes involved in this reduction amination process are glutamate dehydrogenase and/or transaminase.
