Answer: As we all grow, why don’t the cells just get bigger instead of getting more of them? Cells are limited in size because the outside (the cell membrane) must transport the food and oxygen to the parts inside.
Explanation:
B. White petal colour is a recessive trait.
Explanation:
In Mendelian genetics, the alleles depicted in small letters are recessive traits.
Since both alleles are same and in lower case they are homozygous recessive alleles for a white coloured petal gene.
The genotype of the trait will be tt because if it is crossed either with heterozygous or homozygous P alleles it will appear as tt to have phenotypic trait of white colour.
So the genotype will be tt.
Answer:
the organisms are made of more than one cell
Explanation:
Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
The answer is; The slower the cooling the larger the crystals
Slow cooling allows the aqueous molecules of the compound to find a perfect geometry and grow into a large crystal. Fast cooling causes impurities to be incorporated into the growing lattice hence atagonizing the growing crystals.
