Answer:
Hydrogen Bonds
Explanation:
The nitrogen bases are held together in the center of the molecule by Hydrogen Bonds. The type of sugar found in DNA is Deoxyribose.
C
Remember that weight is calculated as mass * gravity
Explanation:
Weight is the result of the influence of gravity on the mass of an object. Therefore, differences in gravity will cause an object of the same mass to weight differently on a scale. On the moon, an astronaut would weight 1/3 of their weight on earth. This is because the gravity on the moon is approximately 1/3 that on earth. The influence of gravity is also higher the larger the mass of an object.

Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables receive this name because, in an experiment, their values are studied under the supposition or hypothesis that they depend, by some law or rule (e.g., by a mathematical function), on the values of other variables. Independent variables, in turn, are not seen as depending on any other variable in the scope of the experiment in question; thus, even if the existing dependency is invertible (e.g., by finding the inverse function when it exists), the nomenclature is kept if the inverse dependency is not the object of study in the experiment. In this sense, some common independent variables are time, space, density, mass, fluid flow rate[1][2], and previous values of some observed value of interest (e.g. human population size) to predict future values (the dependent variable).[3]
Of the two, it is always the dependent variable whose variation is being studied, by altering inputs, also known as regressors in a statistical context. In an experiment, any variable that the experimenter manipulates[clarification needed] can be called an independent variable. Models and experiments test the effects that the independent variables have on the dependent variables. Sometimes, even if their influence is not of direct interest, independent variables may be included for other reasons, such as to account for their potential confounding effect.
False. Although enzymes work as catalyst, they are not carbohydrates, they are proteins.
