Muscle tissue(smooth) which the stomach itself is made of provides the site for protein digestion and holding the contents until the food can be fully digested by other organs. The muscle movements of stomach also provides the churning action which mixes food with enzymes. Connective tissue like the blood vessels absorbs some of the digested nutrients including water to be carried thru the body by the blood which is a connective tisdue. Blood vessels like capillaries which are where the absorption takes place. Epithelial tissue, which lines the stomach protects it from the acid and enzymes as digestion occurs. Nervous tissues provides the stimulus for the actions or movements for the other tissues at work in the stomach. For example, the churning action of stomach and contractions are caused by nerve impulses on the muscles of the stomach.

Some of these services, or functions, include protecting and improving water quality, providing fish and wildlife habitats, storing floodwaters and maintaining surface water flow during dry periods. These valuable functions are the result of the unique natural characteristics of wetlands.</span>
Homologous chromosomes contain the same genes and the same locations, or loci but may have different alleles. But jsut so this definition makes sense, lets define some of the words.
A gene contains the traits that is passed down from two parents to its offspring. An allele is one part of a pair of genes that are located in a particular spot that controls the same trait.
Answer:
E) Nucleic acids; nucleotides; deoxyribose; ribose; uracil; thymine.
Explanation:
Os dois tipos de ácidos nucléicos são DNA e RNA, eles são formados a partir de nucleotídeos. O açúcar no DNA é a desoxirribose, enquanto no RNA é o açúcar ribose. A sequência de bases nitrogenadas para o DNA é adenina, tiamina, cinina e gianina, enquanto para o RNA é uracila, cinina e gianina.
