Plants absorb nutrients and water through their roots, but photosynthesis — the process by which plants create their fuel — occurs in the leaves. ... The leaves of plants also contain veins, through which nutrients and hormones travel to reach the cells throughout the leaves.
Explanation:
<u>Brief description about how the SHAPE of DNA:</u>
DNA is a double helical structure. The structure of DNA was described by Watson and Creek. They were scientists who got the structure of the DNA by Xray crystallography. They said that the DNA is a double helical structure that is composed of two sugar phosphate backbones that are having one nitrogen base on each sugar molecule.
Each sugar phosphate backbone is at an angle of 36° with the preceding or the succeeding one. They are placed at 20A apart. Each nitrogen base is either Adenine, thymine, guanine or cytosine. Adenine is complementary to thymine and guanine to cytosine. They are complementarily present on the two corresponding sugar phosphates chains. They are 34A to complete one full cycle of the helix.
Answer:
The correct answers are A and B.
Explanation:
Pleiotropy is defined as "when a single gene affects two or more phenotypic characteristic of an organism.". Phenotypic refers to the traits that can be physically observed or measured in an organism, for example height, hair color etc. So the examples of pleiotropy in the given options are in A and B which describe situations where one gene affects two or more phenotypic traits.
I hope this answer helps.
Quartz sand and Black sand are the most common. Each type is formed by rocks breaking down from weathering.
