Answer:
C. the genes for these two characters were on different chromosomes
Explanation:
Mendel conducted several experiments with peas to demonstrate the mechanisms of heredity. He decided to use peas because they self-fertilize, have a short life cycle, are easily grown and produce large numbers of offspring. Peas, in addition to the advantages already mentioned, have simple characteristics to observe, such as the color and shape of the seed. Mendel analyzed seven of these characteristics that had no intermediates: seed texture, seed color, seed coat color, pod shape, pod color, flower position, and plant height.
Through his study, Mendel concluded that the characters "seed color" and "seed shape" showed an independent variety. This is because the genes related to these two traits are distant from each other in the chromosome and therefore have no dependence between them.

Have a nice day!
Answer:
Withering is a process in which a rock gets broken down into small and large fragments which are displace other location by the action of wind, water and ice. There are three types of withering: mechanical ,chemical and biological. Mechanical withering is a process which brings changes into physical structure of rocks like large rocks are converted into small rock. Chemical withering is a process which brings changes in the chemical composition of rock. This withering process can change minerals content in the rock. Biological withering is a process in which living beings uses rock for their survival like plants, animals and microbes causes disintegration of rock.
Highly withered and unwithered rock can be distinguished by following characteristics:
1. Physical structure: There will be no change in the structure of unwithered rock but structure of highly withered rock will change after the withering process.
2. Chemical composition: The withering process will remove surface and internal minerals present in rock. In unwithered rock the surface and internal mineral composition will remain unchanged but in highly withered rock the surface and internal minerals present in rock will be removed, which change the overall chemical composition of the rock.
Answer: The charges of the objects are A: Positive and B: Negative.
Explanation-
The electric field lines are pictorial representation of the electric field in terms of imaginary lines.
The direction of electric field is away from the positive charge and is directed towards the negative charge.
In this question, the electric field lines are emerging from A and coming towards B.
Thus, the right answer is A: Positive and B: Negative.
