The process by which new species are formed
It is a carbohydrate, specifically a <span>polysaccharide</span>.
Answer:
B
Explanation: I’m just using common sense. If part of the prairie grass is destroyed, that would mean less food for the bison. Which in turn would result in a decrease of Bison?
Answer:
by the sarcoplasmic reticulum's calcium ion pumps
Explanation:
Rigor mortis or postmortem rigidity, is a state caused by chemical changes in the muscles that occur post mortem and cause the limbs of the corpse to stiffen.
This occurs because after death, there is no cellular respiration and consequently, no oxygen nor ATP (ATP is required for the muscle relaxation).
Calcium enters the cytosol after death because it is released due to the deterioration of the sarcoplasmic reticulum and due to the breakdown of the sarcolemma. Ca2+ ions activate the formation of actin-myosin cross-bridging necessary for the contraction. Muscles are unable to relax, because myosin heads continue to bind with the active sites of actin and there is no ATP to destabilize the myosin-actin bond.
Acclimation is the physiological response or phenomenon which is responsible for survival of salmon in fresh water and salt water.
When a young salmon starts its sea journey it travels wide distances in search for oceans completing a leg of their journey. They travel back to home streams for spawning. This survival in different osmotic potentials and salinity is due to osmoregulation and acclimation. System of salmon detects saline change and instigates a negative feedback system to the body water concentration. Similar feedback works contrastingly when salmon is in fresh water or marine streams of water.
Hence, the physiological response occuring in salmon is acclimation.
