The correct answer is (d.) proteins. Higher organisms use nitrogen to make their protein. Food that is containing protein also involves nitrogen in it. Protein also has amino acids that contain nitrogen in it which is a necessary essential nutrient for the body.
<span>For the answer to the question above,
DD <-- all (homozygous) dominant
dd <--- all (homozygous) recessive
DD-X dd
__d__d
D Dd Dd
D Dd Dd
^your Punnett square
since there is a dominant gene in Dd, Dd's phenotype will be of the dominant. Therefore, an all dominant allele X an all recessive allele will yield an all dominant phenotype offspring.</span>
I guess the point about increasing level of oxygen is most correct......
Answer:
how can we know the substance if u didn't attach any diagram to this question
Answer:
T/ T genotype
Explanation:
To know which genotype appears to be associated with a higher prevalence of heart disease, you must know which genotype appeared in the highest percentage in the population tested.
For this, we will do the following calculations.
200 people = 100%
20 people = X
X = (20 * 100) / 200
X = 10%
This means that the C/C genotype appeared in 10% of the tested population.
Now we must to know the percentage of the T / T genotype, we must consider 200 of the 250 people tested.
250 people = 100%
200 people = x
X = (200 * 100) / 250
X = 80%
----
200 people = 80%
30 people = X
X = (30 * 80) / 200
X = 12%
Thus, we can say that the T / T genotype appeared in a higher percentage within the tested population, being considered the genotype that seems to be associated with a higher prevalence of heart disease.
