Answer: False
The variations in expression depends on how genes code for proteins
that would specify whether it will be dominant or recessive allele. Within a population, there may be a number of
alleles for a given gene and these differences
can cause variations in the protein that is produced. The change in protein
expression affect traits due to the variations in protein activity or
expression that produce different phenotypes.
<span>Moreover, individuals that have copies of
different alleles are known as heterozygous
and individuals that have two copies of the same
allele are referred to a homozygous. The expression patterns observed in
inheritance will depend on whether the allele is found on an autosomal
chromosome or a sex chromosome, and on whether the allele is dominant or recessive.</span>
Answer:
Good question! Hamburgers actually get their name from Hamburg, Germany, home of a cut of beef called the Hamburg steak that eventually evolved into what we now consider hamburgers
Answer: True.
Explanation: I took the test on K12 and received an A.
The correct answer is A. Experimental group
Explanation:
In experiments, the experimental group refers to the group of subjects that receives special treatment or in which the scientist or researcher intervenes. This is the opposite of a control group that does not receive treatment and therefore, it is used as a reference to measure the effect of the treatment.
This implies, in the experiment presented Group A is the control group as they do not have special treatment because they sleep normally and Group B is the experimental group as the researcher modifies their sleep time and reduces it two hours which means in this group there is a treatment or intervention.
