When a question states that the plants are "homozygous for the contrasting traits," that means that the plants will have the same letter genotype for both of their chromosomes. In other words, if we use the letter "b" as our chromosome, one plant will have the genotype "BB", and the other will have "bb." Now, there will only be on expected genotype with these, and that would be "Bb." To find this, you must put the genotypes in a punnet square and calculate the different genotypes. The big B is dominant over the little b, so in this case the offspring plant will have a heterozygous for both traits.
The answer is mitochondrion.
Mitochondria are critical for the cell’s biochemical processes that require energy to be powered. Mitochondria are responsible for generating this power in the form of ATP through a process called chemiosmosis. Without ATP, the cell would immediately die since it would be incapable of performing virtually all biochemical processes that re required to sustain life.
The answer is C) polysaccharide
<span>The exception is inert and impermeable. Cells are rather fluid and permeable. Cells membranes are fluid because the phospholipids that compose the membrane are made of unsaturated fats. Also, cholesterol is intercalated between these fatty acids chains hence the membrane is never compact. The permeability of the membrane is enabled by the presence of pores in the membarne made by transmembrane proteins that run from outside to the inside of the cell.</span>
I think the correct answer among the choices listed above is option C. The correct order of organizations of structures in living things from simplest to most complex should be c<span>ells as the most basic unit of life, Tissues, Organs and Organ Systems. Hope this answers the question.</span>
