Amino acids and sugars are both required by animals to maintain their health. Without a diet containing both of these, animals cannot survive. Amino acids are obtained by animals when they digest .
A) nucleic acids
B) carbohydrates
C) proteins
D) lipids

c

Explanation:

Amino acids are the monomers of protein molecule.Each amino acid molecule is made up of an amine group,caboxylic acid  group,Hydrogen atom and R-group. All are attached to the alpha  carbon.It is the R-side group that differentiate one amino group from another.

These amino acids units are joined together by the peptide bonds to form the giant protein molecules

The arrangement, the number of the amino acids and the orientation of these  amino acids  can be used to classify protein into different primary,secondary, tertiary and Quaternary levels.

Generally protein digestion begins and ends in the stomach and the small intestine. by enzymes pepesin and renin, and the activities of enzymes of the pancreas  chymotrypsin and trypsin,respectively.

The cells in the wall of the small intestine finally breakdown the digesting protein into amino acids by the activities of the enzymes there.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
