Correct Answer: Synapse
Explanation:
The functional connection between two neurons is a Synapse.
Correct Answer: FALSE
Explanation:
In Type 1 diabetes, body do not produce any insulin. In type 2 diabetes, body can produce some insulin.
Hence, the given statement that most type 2 diabetics do not produce insulin is "FALSE."
Correct Answer: The definition of Lysogeny is a dormant viral infection of bacteria in which the genetic material of a virus combines with that of a host bacterium
Correct Answer: scala vestibuli
Explanation:
The oval window is connected directly to scala vestibuli.
Correct Answer: Layered
Correct Answer: The ultimate source of new alleles is mutation, random changes in the nucleotide sequences of an organism's DNA
Correct Answer: absorb sunlight
Explanation:
Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
Correct Answer: Nuceotides
Explanation:
A molecule of DNA is a polymer composed of nucleotides. Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group.
Correct Answer: guanine - cytosine
Explanation:
The correct pairing of DNA bases among the given options is guanine - cytosine.
Correct Answer: 120 days
