False. It can and will dissolve in water.

Answer: True.

Explanation:

Organic fats are nonpolar molecules, while water is a polar molecule.

Since fats do not have any polar part in its structure, to be dissolved in water they would have to break some of water's hydrogen bonds. But this does not happen, so the fat is forced to stay separate from the water. This means nonpolar molecules are repelled by water and do not dissolve in it. They are hydrophobic compounds. So the lipids just float in the water without blending into it.

How does the strength of a sound field 1 meter from its source compare with its strength 4 meters away?

Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form, intensity I is

Example 1: Two different enzymes are able to catalyze the same reaction, A → B. They both have the same Vmax, but differ their K

luda_lava [24]

Answer: (a) = 0.022mmoles/minute; (b) = 0.00022mmoles/minute; (c) = 0.022mmoles/minute

Explanation:

The Michaelis- Menten equation is used to show the relationship between substrate concentration and reaction rate.

The equation is Vo = Vmax[S]/(Km + [S]

where Vo is the initial velocity, Vmax is the maximum velocity, [S] is the substrate concentration, Km is the Michaelis constant.

(a) For enzyme 1; Vo = 0.002mmoles/minute, Vmax = ?, [S] = 0.1mM, Km =1.0mM; making Vmax subject of the formula;

Vmax = Vo * (Km + [S])/ [S]

Vmax = 0.002*(1.0 + 0.1)/ 0.1

Vmax = 0.022mmoles/minute (Vmax for Enzyme 1&2)

(b) Vo = Vmax[S]/(Km + [S]

Vo = 0.022 * 0.1/(10+0.1) = 0.00022mmoles/minute

Vo = 0.022*1000/(1.0+1000) = 0.022mmoles/minute

Distinguish between dimorphic, polymorphic, and continuously variable traits.

jolli1 [7]

Dimorphic, polymorphic, and continuously variable traits are distinguished as follows:

Dimorphism is the condition of those species of animals or plants that exhibit two anatomical aspects or two different forms.

When talking about polymorphisms in genetics, reference is made to the different variations that may exist on the DNA of the same gene.

Continuously variable traits are those that show a continuous distribution of phenotypes.

Therefore, we can conclude that dimorphism is a polymorphism with only two forms, the polymorphism is any stable change of the DNA fixed in the population and in continuously variable traits the phenotypes show a continuous series and cannot be easily grouped.
