<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:
Increases
Explanation:
Biomagnification refers to a phenomenon in which the harmful toxic chemical gest magnified or amplified or increases in the food chain trophic level.
The biomagnification is caused by the bio-accumulation of the toxic material in the organisms.
The harmful toxic chemical enters the food chain through eating like when the crops are sprayed with pesticides and insecticides runoff in the water. From there the toxic material enters the aquatic food chain like from the planktons to fish and then to vultures.
The organisms at higher trophic level die because of the accumulation of the infected lower trophic organisms.
Thus, Increases is the correct answer.
It states that, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature, assuming in a closed system.
p1/t1=p2/t2
antonio is considering that since the spiders came first, it cannot have 'derived traits' from anything. spiders themselves are the ancestralspecies of the insects
