The area “hotspots” known as the Hawaiian island.
Answer:
here is your answer
Explanation:
Much of the energy, estimates suggest from 60% to 70%, is used to power transport mechanisms that maintain the Na+-K+ membrane potential required for the transmission of the nerve impulses. The brain must also synthesize neurotransmitters and their receptors to propagate nerve impulses.
Answer: option B - most of the water reaching the collecting ducts is not reabsorbed
Explanation:
Anti-diuretic hormone is a hormone secreted by the posterior pituitary gland. It acts on the kidney to regulate fluid and salt balance in the body by the reabsorbtion of useful fluid (water) from urine.
Thus, when antidiuretic hormone (ADH) levels are low most of the water reaching the collecting ducts is NOT reabsorbed, resulting in the passage of LARGE volume of dilute urine.
Explanation:
These questions are related to the extraction of DNA using detergents and ethanol.
1. Consistency and texture- the extracted DNA is white, spongy and moist or slime in nature.
2. Salt is used during the extraction process as the DNA is negatively charged molecule and to neutralize the negative charge which will allow the formation of precipitate.
3. The DNA is soluble in aqueous solution as the DNA is a negatively charged molecule therefore the negative charge makes it a polar molecule and it can form the interactions in the aqueous solution.
4. RNA could be present in the aqueous solution along with the DNA as both are the nucleic acid.
5. The base-pairing rule was suggested by the Chargaff who proposed that Adenine binds thymine and guanine binds cytosine.
5. The binding of adenine to thymine involves two hydrogen bonds and between guanine to cytosine involves three hydrogen bonds.
