Cohesion helps plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. This transport occurs even in large trees and against gravity. Transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.
Answer:
evaporation
Explanation:
the liquid evaporated over night
The answer is phospholipids. The phospholipids are a group of lipids that are main constituent of all cell membranes in which they can make lipid bilayers because of their amphiphilic feature. The arrangement of the phospholipids molecule primarily includes of two hydrophobic fatty acid tails and hydrophilic head consisting of phosphate group. The two constituents are linked by a glycerol molecule and phosphate class can be altered with organic molecules such as choline.
Answer:
B
Explanation:
We never see short bristle males, suggesting some type of lethality. I.e. any males who inherit the mutation die before birth so we don't see the phenotype. This also hints that it could be X-linked.
Females can be short bristled, but males can't, as it is likely lethal. This suggests that having one copy of the short bristle trait without the long bristle trait is lethal (as males as XY and so only have one copy of the trait). The female then must be heterozygous for the short bristle trait (which also explains how in generation F2, long bristle males can be produced, as if she was homozygous males would all be short bristled, and therefore dead, so there would be no males.
Since the first short bristle female is heterozygous, the trait for short bristles must be dominant.
However, since evidence suggests the trait is X-linked, it cannot be autosomal, as suggested in B.
