Answer:
here are two alleles for freckles describes the presence of freckle in one of the sibling.
Explanation:
Freckles are the dominant trait in the human.
There are two alleles for a gene on the homologous chromosome responsible for the trait to be with freckle or no freckles.
In the situation when one child can have and other does not have freckle it shows that parent are heterozygous for the freckle gene.
In heterozygous form one allele will be of dominant and other is of recessive nature.
The cross between the heterozygous parents is shown as:
F f
F FF Ff F is freckle f= no freckle
f Ff ff
From the punnet square it can bee seen that there is 25% chance of no freckle in a sibling when both the parents have freckle.
Other chance is if one of the parent is heterozygous and dominant and the other parent is recessive. From the punnet square
F f
f Ff ff
f Ff ff In this case 50% chance of no freckles in offspring.
So in either case chance of no freckled child is there.

<span>Polypeptides are just actually proteins which
are unfolded. And so we ask how are proteins made? Remember that we learned
about DNA being transcribed to mRNA, and then those mRNA's 3-letter codons are
being translated by ribosomes into a polypeptide chain, and then finally folded
into a protein. So yes, the answer is C.</span>
The primary function of a neuron is to receive messages from the senses and then respond with motor activity such as a finger being burnt and thpe arm muscle pulling the finger out of harms's way. So safety is part of it. Another function is to use sensory neurons to evaluate a scientific understanding of the world, such as determining which mineral is being looked at ie by its' colour, hardness, crystal system etc.
my understanding is that they evolve over time, one could say adapt, to survive to mimic other creatures, im sure there are plenty of books you could borrow from a library or buy online to learn more, and there are different studies people have done you might be able to find free online!!!
