Answer:

Option A

Explanation:

The rate and amount of decomposition of alcohol depends on the amount of body fat in an individual. The activity of enzyme alcohol dehydrogenase that breaks down alcohol is affected by concentration of body fat and water.  

The higher the body fat and the lower is the body water and fluid, the higher is the activity of enzyme alcohol dehydrogenase.  

Thus, the higher activity of enzyme alcohol dehydrogenase ensures higher rate of breakdown of alcohol due to which level of alcohol concentration in blood of  an individual reduces.  

Hence, option A is correct

Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then,
Sveta_85 [38]

The correct answer would be that substance A is rice, and substance B is sugar.

For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.

Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.

Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

In Oompa Loompas, gray face (G) is dominant to orange recessive face (g). If two gray faced Oompas have an offspring with an ora
Neko [114]

Answer:

The genotype for each of the parents must be

parent 1 : Gg

parent 2 : Gg

Explanation:

Please note that a dominant trait is a trait that is expressed phenotypically in a heterozygous state, while a recessive trait is a trait that can only be expressed in a homozygous state.

Now, since gray face (G) for Oompa Loompas is dominant, and orange face (g) is recessive, for an offspring to be orange faced, it means that the genotype of the offspring must be 'gg'. Also, since both parent contribute an allele in the pair of alleles in the offspring, both parents must have the recessive (g) in their genotype. Moreover, we are told that both parents are gray-faced, meaning that their genotypes were 'Gg' and 'Gg'. To confirm, let me do the cross

                                 G           g

G                                GG       Gg

g                                 Gg        gg

from the cross above, we find out that out of 4 offspring, 3 were gray face (GG, Gg ) while one was orange face (gg).
