All macromolecules have carbon atom and the hydrogen atom.
<h3>What are macromolecules?</h3>
The term macromolecules refers to the molecules that are composed of smaller units. These smaller units are called monomers. The macromolecules that we are concerned with here are the macromolecules that could be found in the human body.
The biological macromolecules are often very large as we can see. This is because the number of units that are joined to form the macromolecules are usually very much. There are thousands of monomer molecules that are joined together to give proteins, lipids, carbohydrates and the nucleic acid macromolecules.
All the macromolecules have the carbon atom and the hydrogen atom. These are found across all the macromolecules. The carbohydrates are reducing sugars thus they contain the carbonyl bond. The carbonyl group is absent in lipids, nucleic acids, proteins, and amino hence they do not undergo carbonyl reduction reactions.

Answer:
A scientific model is a representation model for a certain scientific concept. Scientific models make it easier to study a phenomenon as they tend to model out the exact phenomenons.
A drawing of an skeleton would be unclear as the children might not be able to locate certain features in the drawing. For example, a certain joint could be missed by the teacher in the drawing or the child might not exactly be able to locate where the joint or bone is present.
But as the model will be more real to the actual skeleton system hence, studying through a skeleton will make it a lot easier to study the human skeletal system.
It is the part of the cell cycle in which the dna is replicated! vote me brainliest please :) ❤️
Mendel observed phenotypic traits during the cross of pea plants. Subsequently, he noted each trait had only two forms.
<h3>Mendel's Experiments</h3>
Mendel crossed pure-breeding pea plants, and then he crossed hybrid generations, as well crossed the hybrid progeny back to parental lines.
From these crosses, Mendel observed the descendence and then formulated a series of inheritance principles.
Mendel noted traits can be divided into dominant and recessive phenotypic characteristics.
Dominant characteristics were inherited in an unaltered manner after hybridization of true breeding [plants.

Answer:
b. False
Explanation:
Channel proteins use passive transport, that is, they do not require energy such as ATP for transporting molecules.
