The most common organisms with exoskeletons are arthropods which include insects (bees, ants), arachnids (spiders) and crustaceans (lobsters and crabs).
Answer:
<h2>Genotype, sequence, mRNA, cytoplasm, proteins, phenotype</h2>
Explanation:
The allele combination at a gene locus is known as an organism's genotype, which after expression define the phenotype of that organism.
Th sequence of nucleotide in the DNA then transcribed to produce mRNA by RNA polymerase. Then mRNA exported into the cytoplasm and works as template for the synthesis of protein. This protein defines the phenotype of that organism.
Answer:
The statement is false.
Explanation:
At the base of the oxyntic gland, in addition to the parietal cells, the chief cells (peptic cells) are located, mainly in the lower half of the gastric glands, these cells have large basophilic zymogen granules, more prominent in the apical region and responsible of the secretion of pepsinogen proteolytic enzymes, a relatively constant fraction of pepsinogen I released by the chief cells is absorbed by the blood instead of passing into the gastric lumen. The stomach acid transforms pepsinogen into pepsin, which breaks down proteins in food during digestion.
