Answer:
True
Explanation:
that would be my best guess
The purpose of the cell membrane is to hold the different components of the cell together and to protect it from the environment outside the cell. The cell membrane also regulates what enters and exits the cell so that it doesn’t lose too many nutrients, or take in too many ions. It also does a pretty good job of keeping harmful things out.Ions and large polar molecules cannot pass through the lipid bilayer. But more specifically, whether a molecule can pass through the membrane depends on its size and its electrical nature. The membrane is highly permeable to non-polar (fat-soluble) molecule.
Answer:
Tt, Tt, tt, tt.
Phenotype: two tall and two dwarfs
Explanation:
The F1 generation will be the crossing of True tall and true dwarf plants to give all tall plants. Kindly note that the genotype for true tall plants is represented by TT, and the genotype for true dwarf plants is represented by tt. The crossing of the two true tall and true short gives Tt, Tt, Tt, Tt; in which the phenotype = all the plants are tall.
If the F1 generation is crossed with the true dwarf plants that is; Tt with tt. It gives us:
T t t t.
Tt, Tt, tt, tt. So, the phenotype is two tall and two dwarfs and the genotype is 2 of Tt and 2 of tt.
