Answer:
1:2:1
Explanation:
When we say genotype, we are talking about the different type of allele combinations. Phenotype is when you are looking at dominant recessive ratios.
The correct answer is C. Passive transport refers to the movement of substances such as ions across the cell membrane without the use of energy. Examples of such movement is diffusion, facilitated diffusion, osmosis and filtration. The opposite of passive transport is active transport and this needs energy to occur. Examples of active transport are proton pumps, exocytosis and endocytosis.
Answer:
A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
Salt reduces the amount of water in a solution, because you're introducing another molecule. If the water concentrations are different, the water is going to want to reach an equilibrium to balance itself out. Because the salt solution has a higher water concentration than the plant cell, the water will move into the cell to try and balance out the concentrations. If the salt solution had a lower water concentration (water potential) then water would move from the cell into the solution.
