Answer: The water roll off the surface of a leaf as it has a layer of wax on the surface of the leaves. As a result the leaves of plant cannot absorb the water through the leaves. The water rolls off instead of getting absorbed.
Explanation:
Answer:
50%
Explanation:
According to the given information, the allele for the red-green colorblindness is inherited in an X linked recessive manner. Let's assume that the allele X^c is responsible for red-green colorblindness. The woman is normal but had a colorblind father (X^cY). Fathers give their X chromosomes to the daughters while their Y chromosome is transmitted to their sons. The sons get their X chromosomes from the mother.
The colorblind father has transmitted the X-linked allele for the red-green colorblindness to his daughter. Therefore, the genotype of the woman is X^cX. The woman would produce two types of eggs: 50 % with X^C and 50% with X. Therefore, 50% of sons of this woman would get X linked allele for the red-green colorblindness and would be affected by the disorder while the rest 50% of her sons will be normal.
Answer:
See the answer below
Explanation:
These bases are of two different types of molecules: purines and pyrimidines. Purines have <u>double carbon-nitrogen</u> ring(s) in their structure, and pyrimidines have <u>single carbon-nitrogen</u> ring(s) in their structure. 6. The two bases that are purines are <u>Adenine</u> and <u>Guanine</u>. These bases are comprised of <u>double</u> rings. 7. The two bases that are pyrimidines are <u>Thymine</u> and <u>Cytosine</u>. These bases are comprised of <u>single</u> rings. 8. Based on this information, scientists could predict that the base <u>Adenine</u> pairs with <u>Thymine</u> and the base <u>Guanine</u> pairs with <u>Cytosine.</u>
<em>The purine and pyrimidine bases both form parts of the components of the nucleic acids. Purines have double C-N ring structures while pyrimidines have a single C-N structure. The purine bases include Adenine and Guanine while the pyrimidine bases include Thymine (or Uracil in RNA) and Cytosine. According to Chargaff's rule, purine (Adenine/Guanine) pairs with pyrimidine (Thymine/Cytosine).</em>
