Answer:
Biological populations of same species become isolated due to geographic changes such as mountain building or emigration.
Explanation:
Answer:
inter-phase
Explanation:
The Eukaryota cell spends most of its "life" in inter-phase of the cell cycle, which can be subdivided into the three phases, G1, S and G2. During inter-phase, the cell does what it is supposed to do. Though cells have many common functions, such as DNA replication, they also have certain specific functions.
<h2>functional group of different compounds</h2>
Explanation:
- A functional group is a particular design of iotas usually appended to the carbon skeleton of a natural atom. Practical gatherings give particular synthetic properties to the particles of which they are a section. Particles commonly found in practical gatherings incorporate oxygen, nitrogen, sulfur, and phosphorus.
- (OH) Alcohol is one of the most polar and may act as a weak acid
- (COOH) Carboxylic acid serves as the acid.
- (C=O) Aldehyde: can be an isomer of a chemical ketone
- (S-H) Tthiol usually transform to a disulfide bond
- (NH2) Amine serves to be the base of chemical compounds
- (PO4) Organic phosphate carries a negatively charged atom.
Answer:The ER also contains domains that contact the plasma membrane (PM) and other organelles including the Golgi, endosomes, mitochondria, lipid droplets, and peroxisomes.
Answer:
D. increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure
Explanation:
Activation of the sympathetic division under any emergency or stress conditions results in a series of physiological responses collectively referred to as flight or fight response.
The sympathetic nervous system causes an increase in heart rate and blood pressure. Increased pumping of blood through the heart ensures enough supply of oxygen to muscles required to produce the desired responses.
It also causes constriction of blood vessels that supply gastrointestinal tract and reduced muscular activities of smooth muscles of GI trait. The result is reduced blood flow through these tissues, reduced peristalsis and slowing of digestive activities, which are not required during exercise. The sympathetic nervous system also triggers the release of glucose by the liver increases blood glucose level.
