I don't know what the expieraments about but I can say its rather B or C the independent variable is the variable that you are testing.
Answer:
Rapid eye movement sleep (REM) may be defined as the the phase of the sleep that are unique to the mammals. This sleep is marked by the muscle tone.
The REM leads to the increase in pressure with deprivation. This leads to the increase in the rapid eye movement and plays an important role in the REM sleep and dreaming of the individual and quite necessary in the adult.
The law of dominance states that the recessive genes are always masked by the dominant genes.
The genes for brown fur will mask those for white fur.
If there are 160 bunnies then 120 of them have brown fur and 40 have white fur.
Thus, 40 bunnies should be white according to the Punnett square.
<span>Foods that are highly acidic tend to inhibit bacteria growth. Many times, bacteria do not acclimate well to acidic environments, so having a food with a very low pH will help to make sure that the bacteria can't thrive in such an environment. Fruits and vegetables are good examples of these types of food.</span>
Answer:
Explanation:
Mutation is a sudden heritable change in the genome of an organism.
Substitution is a form of mutation whereby a base pair is been substitued for by another base pair resulting in a serious damage.
Codon are three alphabeth coding for a particular amino acid.
When substitution occurs in a base pair and the replacement forms a protein that has the same function as the one that was removed there will be no observable in the phenotype. Hence, If the adenine in the 15th position of the sequence is changed to a guanine, the person may not have cystic fibrosis.
But when a particular base pair is substituted for and an entirely new protein or amino acids results with a different functions and structure it could lead to a serious damage or healthy issue. Hence, If the adenine in the 15th position of the sequence is changed to a guanine, the person does have cystic fibrosis.
