<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.
In order to be sure you are always have enough of the right food in hand and get the best prices, in a situation in which customer dogs have many different dietary needs, and a lot of vendors on the other hand, you should use<span> a supply chain management system (SCM) to track vendor information, food usage trends, and food expiration. With SCM you will manage the flow of goods.</span>
Answer:
Primary structure and quaternary structure because the heat energy will disrupt only the weaker interactions which causes the secondary and tertiary structure to break down.

Answer:
Only Photosystem I - 1, 5, 6
Only photosystem II - 3, 2
Both Photosystem I and II - 4
Explanation:
Only Photosystem I
a) Reduction of NADP+ - uses light energy to convert NADP+ to NADPH2
b) Reduction of electron transport chain between the two photosystems
c) Oxidation of electron transport chain between the two photosystems.
Only photosystem II
a) Oxidation of water - here the absorbed light energy is used to dissociate of water molecules to produces protons (H+) and O2 along with free ions
b)Reduction of primary electron acceptor - An electron is taken by pheophytin which is a primary electron acceptor molecule that is located within photosystem II and hence it get reduced.
Both Photosystem I and II
a) Light is absorbed in both photosystem I and II. While in photosystem I, light waves of large wavelength i.e 700 nm are absorbed, in photosystem II light waves of short wavelength of i.e 680 nm are absorbed.
By placing the pots with detergent in the sun and the pots
without detergent in the shade, the student is not comparing the effects that
detergent has in the growing rate of the seeds under the same conditions;
besides, he does not have a control group. Therefore, he will not be able to
determine if the growing rate of the plants were affected by the detergent, the
lack of sunlight, or a combination of both factors.
