<h2>Answer 1 with Explanation</h2>
The DNA model represents the genetic code that defines all the characteristics of a living thing and it is made up molecules called nucleotides. Each nucleotide contains and represents a phosphate group, a nitrogen base, and a sugar group. Two long strands are formed by Nucleotides attached together to create a structure called double helix which looks like a ladder, the sides would be made up of sugar and phosphate molecules while the rungs would be the base. The straws represent the sugar-phosphate backbone which forms the structural framework of nucleic acids. It is composed of alternating sugar and phosphate groups.
<h2>Answer 2 with Explanation</h2>
The push pins re-presence nitrogen-containing base is an essential molecule with a nitrogen atom having the chemical features of a field. The principal biological purpose of a nitrogenous base is to bond nucleic acids collectively. A pushpin owes its essential characteristics to a solitary couple of electrons of a nitrogen atom. It is assigned as the derivatives pair of parent compounds.
<h2>Answer 3 with Explanation</h2>
The paper clips represent ‘five prime’ and ‘three prime’ which indicate the number of carbons in the DNA’s sugar backbone. These two are the distinctive ends of the nucleic acids. The black dots represent the bonds of sugar and phosphate which make up the nucleotides and show the genetic code. These bonds have strong covalent bonds that keep the bonds attached together firmly.
Answer:
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
A. The following statements are hypotheses:
1. Glucose may cause an increase in bacterial growth.
2. Increased glucose may lead to capsule formation in bacteria.
B. The following statements are observations:
1. The bacterial colony grown without glucose do not have capsules around their cells.
2. Bacteria growth in the glucose environment increase rapidly and then stopped after sometime.
In scientific reasoning, a hypothesis is made before any applicable analysis has been done. A theory, on the opposite hand, is supported by evidence: it is a principle shaped as an effort to clarify things that have already been supported by knowledge<span>.
</span>For example: “It's bright outside.”
Hypothesis: A projected clarification for a development created as a place to begin for additional investigation.
Theory: A well-substantiated rationalization nonheritable through the methodology and repeatedly tested and confirmed through observation and experimentation
