Quick answer: Food enters the human digestive system through the mouth before then moving through the pharynx, esophagus, stomach, intestines, rectum and anus.
Answer: b. littoral
Insects are most likely found in the littoral aquatic zone. Littoral zone are rich in oxygen and has abundant and diverse food resources. Therefore, this zone supports high diversity of insects. Large taxa of insects like aquatic beetles and bugs, caddisflies, dragonflies and damsflies are important littoral zone communities.
Answer:
A. Because of base pairing, each strand has all the information to serve as a template for the other strand.
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two antiparallel polynucleotide chains. This double helix serves as a template for its own duplication. DNA templating refers to the process by which a portion of the DNA molecule in a single strand is used as a template to be copied by complementarity base pairing. According to base-pairing rules, Adenine (A) always pairs with Thymine, while Guanine (G) always pairs with Cytosine (C). These nucleotide bases are each linked with their complementary base by hydrogen bonding. When base pairs separate, the hydrogen bond acceptor and donor groups of each strand allow the addition of nucleotides and synthesis of new DNA strands, a process catalyzed by specialized enzymes (DNA polymerases).
Answer:
Animals obtain glucose in their diet. During metabolic reactions, animal cells use glucose: to make glycogen which is stored in the liver and muscle cells to make lipids from fatty acids and glycerol All cells require glucose for respiration.
