Dominant: the more common trait (brown hair)
Recessive: a trait that doesn't show up unless both parents carry it (blue eyes)
Co- dominant: both traits show up and co- exist (AB blood)
Incomplete dominance: when a dominant gene does not completely mask a recessive gene so they blend (pink flower)
Phenotype: physical trait- able to be seen (stripes on a zebra)
Genotype: genetic makeup of an organism - genetic trait
Hetrozygous: different (Bb)
Homzygous dominant: same and dominant (bb) and (BB)
Purebred: same as homzygous- has same alleles (bb) and (BB)
Hybrid: also known as heterozygous traits

I think the propositions are :
Which organisms and set of characteristics are correctly paired?(1) fungi—carry out photosynthesis and heterotrophic nutrition(2) plants—carry out respiration and autotrophic nutrition(3) decomposers—carry out photosynthesis and autotrophic nutrition(4) animals—carry out autotrophic nutrition and heterotrophic nutrition
1): False because fungi do not have photosynthesis.
3) False because decomposers do not have photosynthesis.
4) False because animals do not have autotrophic nutrition.
2) is true because animal carries out respiration like other living organisms, and carry out autotrophic nutrition by photosynthesis.
Answer:
The underlying principle of SEC is that particles of different sizes elute (filter) through a stationary phase at different rates. This results in the separation of a solution of particles based on size.
hope it helped
<span>The phase of mitosis during which the mitotic spindle begins to form is
PROPHASE.
</span>At prophase, the nuclear envelope is broken down; the chromosomes disperse into the cytoplasm, condenses and become visible;
and more importantly, the mitotic spindle fibers form.
