A substance that releases Hydroxyl Ions in water is called a Base
Answer:
The most common gene therapy vectors are viruses because they can recognize certain cells and carry genetic material into the cells' genes. Researchers remove the original disease-causing genes from the viruses, replacing them with the genes needed to stop disease.
Explanation:
Answer:
B. acidity of the vagina
Explanation:
The genus <em>Lactobacillus</em> includes rods and coccobacilli that lack catalase and produce lactic acid as the main fermentation product. <em>Lactobacilli </em>grow optimally under slightly acidic conditions. They are part of the normal flora of the human body and are present in the intestinal tract, vagina, etc.
In the human female vagina, the <em>Lactobacilli </em>are rarely pathogenic and rather serve as antimicrobial agents and prevent the growth of pathogenic microbes by imparting acidic pH to the vagina. Production of lactic acid by these bacteria imparts acidic pH and allows them to serve as antimicrobial agents.
Answer:
A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.
Answer:
B) The tall version of the gene is dominant to the short version of the gene.
Explanation:
In the question, its given that both the pea plants are purebred for genetically for height. Therefore, we can already pre-determine the combination of letters for each gene, since purebred means that both letters in the combination are the same.
Tall genes: TT
Short genes: tt
Inputting these into a punnet square would give a result of four possible combinations for the offsprings height:
Tt, Tt, Tt, and Tt (doesn't matter which letter is first)
If <em>all</em> the offspring are tall, despite there being a purebred short parent, then we can assume that the tall gene is dominant to the short gene. (Dominant alleles when paired with sub. alleles have the result of the dominant gene actually showing up. In this case, Tt, where the plant is tall due to the T allele regardless of the presence of the short allele t.)
Hope that helped!
