Answer:

D

an increase in the length of the fatty acid tails.

Explanation:

As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated

and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and

decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and

more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity

Answer:

1: 7.8 cm

2: .7 cm

3: 5.55 cm

For the other questions, you have to use a ruler yourself and measure using cm. :)

1 cm = 10 millimeter. To convert, just add a 0 to the end of cm to find the mm (or move the decimal one place to the right.)

For example, 2.6 cm = 26 mm / 5 cm = 50 mm. Hope this helps!

Watson and Crick first built a triple-helix model of DNA. In this model, the nitrogenous bases were on the outside of the DNA mo
Sedaia [141]

Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.

<h3>What is DNA molecule?</h3>
  • Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
  • Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).
  • An alternating sugar-phosphate backbone is created when the nucleotides are linked together in a chain by covalent connections (also referred to as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next.
  • To create double-stranded DNA, the nitrogenous bases of the two distinct polynucleotide strands are joined by hydrogen bonds in accordance with the base pairing principles (A with T and C with G). Pyrimidines and purines make up the two families of complimentary nitrogenous bases.
