The correct answer is A. Apical meristem
Explanation:
In plants, the primary growth refers to the type of growth that increases the length of the stem or toots in opposition to the secondary growth in which the stem thickens and that occurs as the result of the vascular cambium. However, in the case of primary growth, this can be explained mainly due to the action of apical meristem that is a type of tissue located in the tips of roots and the stem and therefore the type of tissue in which the growth takes place mainly through cell division. Considering this, it can be concluded primary growth is due to the action of the apical meristem.
Answer: b. causes the gastric glands to increase production of gastric juice.
Explanation:
The parasympathetic nerves are part of the autonomous nervous system. The parasympathetic predominates mainly during "passive responses" of the organism, such as satiety, rest and digestion. Its functions are: Promotes energy conservation, Reduces heart rate, Promotes glandular secretion, Protects the retina from excess light, Promotes emptying of cavities, Promotes rest and repair, Physiologically antagonizes sympathetic nervous system.
The correct answer is air pollution
Answer: Bacteria lack a mechanism for splicing out introns
Explanation:
Factor VII gene is 186k nucleotides long while the protein is 2332 amino acids long. <u>This lenght discrepancy is due to introns interrupting gene</u>, because the cell first transcribes the entire gene and then cuts introns out of the transcript. At the end, it splices the remaining pieces. Prokaryotes don't perform splicing so it can not edit out introns from the primary mRNA transcript. To produce an eukaryote gene in prokaryotes it is necessary to use a reverse transcriptase to get a cDNA sequence without the introns, and then insert that into a bacterial genome.
Answer:
Sugars move from “source” to “sink” ... Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.
