Correct answer - potometer.
Why? - The potometer does not measure the rate of transpiration accurately because not all of the water that is taken by the plant is used for transpiration (water taken might be used for photosynthesis or by the cells to maintain turgidity). The potometer measures the rate of uptake of water.
Answer:
Phenotype ration of Green : other color plant will be 3:1
Genotype ration would be GG:Gg:gg
1:2:1
Explanation:
Let the dominant allele for green color of plant be G
Recessive allele for the above allele pair would be g let us say that "g" imparts black color
Then the genotype of two heterozygous green plants would be "Gg"
Gg * Gg
GG, Gg, Gg, gg
The three individuals of genotype GG, Gg, Gg will have green color
while the gg individual will have black color (as assumed)
Phenotype ration of Green : other color plant will be 3:1
Genotype ration would be GG:Gg:gg
1:2:1
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.
Answer:
Physical exercise and nutrition are two important components in how you respond to stress. When your body is healthy, your mind can be healthy and vice versa. Physical exercise is proven to be a great stress reliever and also helps to improve your overall quality of life.
