Answer:
glucose
Explanation:
Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot.
Answer:
Dark matter provides the gravity that allows the stars to rotate at the same speed.
Explanation:
The stars at the edges of a galaxy are rotating around the galaxy’s center at the same speed as the stars in the middle of the galaxy. How does this provide evidence of dark matter?
Dark matter absorbs light from outside the galaxy, allowing the light of the stars in the galaxy to show the orbital speeds of the stars.
Dark matter emits the light that astronomers need to see the orbital speeds of the stars.
Dark matter subtracts gravity, which allows the stars to rotate at the same speed.
Dark matter provides the gravity that allows the stars to rotate at the same speed.

Answer:
This conclusion best supported by the results of the breeding experiment. "The completely-plated phenotype is controlled by a dominant allele of a single gene."
Explanation:
In the given inherent cross, all the F1 offspring stated a "completely plated" phenotype. This resources that this phenotype is dominant. Interbreeding of F1 hybrids attained the "completely plated" and "low plated" progeny in a 3: 1 ratio. This resources that equally these phenotypes are measured by two alleles of a gene. The F1 hybrids remained heterozygous dominant for the characteristic and passed both recessive and dominant alleles of the gene. Separation of these alleles throughout gamete development fashioned 50% alleles with the foremost allele and rest 50% with the retreating allele. The accidental fusion of these gametes gave the F2 progeny in 3 dominant: 1 recessive ratio
