I need help please I have test tomorrow
Explanation:
Answer:
D, Afferent (primarily outer hair cells) are the most important sensory transducers. Efferent (primarily inner hair cells) are under feedback and “motor control.” is correct
Answer:
The correct answer is D) Infundibulum
Explanation:
The Infundibulum, also regarded as the Pituitary Stalk is an area of the brain that appears like a v-shaped stem which connects the hypothalamus and the posterior pituitary gland.
It functions as a medium by which hormones are conveyed from the hypothalamus into the pituitary gland, and on to the veins.

Answer:
b. False
Explanation:
These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.
The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.
For a PCR reaction to be performed a solution with some components must be prepared. These components are:
- Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
- Forward and reverse primers (to customize the start of the enzyme reaction)
- DNA polymerase (Enzyme required for replication of desired DNA region.)
- DNA Template (the DNA to be copied)
- PCR-grade water
- Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
Nitrogen 14 and nitrogen 15 differ because nitrogen 14 has 7 neurons and 7 protons. Nitrogen 15 has 8 neurons and 7 protons.
