Examples of alkaline are:sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide etc
Correct answer: B). With fewer contractions
The main function of a contractile vacuole is to maintain the sufficient amount of water in the protoplasm of the cell. For the freshwater amoeba contractile vacuole is needed to pump water and maintain a osmoregulation.
But when it is kept in sea water, more contraction is required to expel the water out of the cell in order to make the environment inside amoeba same as of sea water.
Oligonucleotide primers associate by hydrogen bonding to specific sections; primers are then extended.
The structural components of the mammalian nephron where the transcytosis of water increases due to the action of anti-diuretic hormone is/are the collecting duct. ADH is a hormone made by the hypothalamus in the brain and stored in the posterior pituitary gland. It acts on renal collecting ducts via V2 receptors to increase water permeability, which leads to decreased urine formation. This increases blood volume, cardiac output and arterial pressure.
Answer: <span>A) Slow to repopulate
------
Genetic variation is an advantage of sexual reproduction. It increases survival and the ability to adapt in a species. Species with genetic variation can respond better to environment changes, since the genetic variability allows some to be immune to disease or adapt better to a change, and live to reproduce.
Slow to repopulate is a disadvantage because the species cannot recover quickly after a large disaster. It also means they cannot adapt as quickly to an environmental change.</span>
