I think the answer would be c. because for birds with longer beaks, it was easier to eat seeds off a cactus (for example), and for birds with shorter seeds, it was easier to eat seeds off the ground.
the answer is B which is a crack in the topmost section of a glacier. I hope you got this right
Answer:
The structure of the DNA is ideal for the complex function that it plays.
Some of the features of the structure of all DNA molecules are:
<em>Sugar- phosphate backbone:</em>
The sugar- phosphate backbone is ideal for providing the DNA a ladder- like shape which is essential for its functions.
<em>Hydrogen bonds:</em>
The hydrogen bonds present in the nucleotides keep both the DNA strands intact. If the hydrogen bonds were not present then the double helix would not have been able to form.
<em>Coiling:</em>
The structure of the DNA is coiled and super coiled so that it can fit into an organism.
Fimbriae, flagella and pili are all examples of blank structures found in some bacteria.
Explanation:
Similar: Fatty acids are generally long chains of hydrocarbons with a carboxylic acid group at one of the ends. While Lipids are polymers of fatty acids with a nonpolar hydrocarbon chain and a small polar oxygen group.
Different: Fats are actually a type of lipid. Lipids are a major class of biochemical compounds that includes oils as well as fats. Organisms use lipids to store energy and for many other uses. Lipid molecules consist mainly of repeating units called fatty acids.
