<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:
biology is the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin, and distribution.
Explanation:
Biology is important because it can lead to the study of living organisms to help develop biological knowledge and understanding of living processes for a number of different purposes, including treatment of disease and sustaining the natural environment.
Answer: The answer would be viruses
Explanation:
A virus is a bad bacteria, it breaks your cells down instead of building them up. Fungi and bacteria are naturally in your body because they help your metabolism and breaking down nutrients. Animals are able to do this too with their own bactieria. But as I said, viruses dont help you, they only harm you.
Answer:
A nominal scale describes a variable with categories that do not have a natural order or ranking. You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless.
A nominal scale is a scale (of measurement) that uses labels to classify cases (measurements) into classes. Some examples of variables that use nominal scales would be religious affiliation, sex, the city where you live, etc. Example. One example of a nominal scale could be "sex".
For example, Race is a nominal variable having a number of categories, but there is no specific way to order from highest to lowest and vice versa.
