The correct answer is (C) biomass at each trophic level
Pyramid of energy is a graphic representation of amount of energy trapped per unit time and area in different trophic levels of a food chain with producers forming the base and top carnivores the tip. As the biomass of producers are always greater than the carnivores, the pyramid of energy can't be inverted.
A waste product is a product that is made but isn’t necessarily needed eg. A lightbulb will make light energy but it also makes a waste product heat.
Answer:
Imagine that you are a doctor in maternity ward. During your last shift, 20 babies were born. 10 had blue eyes, and 10 had brown eyes. Remember genotypes are the two alleles given for each trait written with a letter . For this activity 8 - brown eyes b=blue eyes. Phenotypes are the physical appearance of the trait. Given the phenotypes, what are the possible genotypes for these babies? The possible genotypes of these babies are Bb, Bb, bb, bb
Explanation:
Bb= Brown eyes babies
bb= blue eyes babies
from the above analogy, it is crystal clear that the babies are of equal genotypic number which reflects 10:10
I think it is C An increase in the activity of nitrogen-fixing bacteria but don’t hold me to that I’m not sure
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.
