Answer:
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Explanation:
Well...
This question is unclear. but.
A dominant trait always shows over recessive. Unless! Someone has two recessive alleles, otherwise that dominant trait would not show. Cause they don't have it in their genes.
Assuming you mean to type:
"In humans, the allele for dimples (D) is dominant to
the allele for no dimples (d). at another gene locus, the allele for broad
eyebrows (B) is dominant to the allele for broad eyebrows (b)."
Man: Heterozygous for both genes means DdBb
Woman: no dimples, and heterozygous for slender eye-brows
means ddBb
Punnett Square
DB Db
dB db
dB DdBB DdBb ddBB
ddBb
dB DdBB DdBb ddBB ddBb
db DdBb Ddbb
ddBb ddbb
db DdBb Ddbb
ddBb ddbb
Interpretation: anywhere that has a capital letter has the
dominant trait.
Dimples+Broad eyebrows : 6 cases out of 16 (3/8=37.5%)
Dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
No dimples+Broad eyebrows: 6 cases out of 16 (3/8=37.5%)
No dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
Answer:
a) Makes the interior of the cell less negatively charged.
Explanation:
Opening the voltage gated sodium channels will cause the sodium to move down its concentration gradient resulting in the interior of the to be less negative.
