Answer:

Active Diffusion

Explanation:

In active transport, a molecule is transported against its gradient which means the flow of molecule is from regions of low concentration to regions of high concentration. In order to carryout such transports, external energy is applied through biological pumps such as sodium-potassium pump (Na+/K+ ATPase) which maintains the resting potential of the cell.

Some times the energy produced by ATP is directly used and this process is known as primary active transport/diffusion

For energy, a plant breaks apart some of the small sugars it builds. What does the plant do with the rest of its small sugars?

balandron [24]

Answer:

The plant stores them as starch

Explanation:

A typical plant synthesizes sugars from photosynthesis by using water and carbon dioxide.

$6CO_2 + 6H_20 + energy --> C_6H_1_2O_6 + 6O_2$

Parts of the sugar synthesized via photosynthesis is used to generate energy during respiration. The energy generated is useful for other metabolic processes in the plant's body.

$C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_20 + energy$

<em>The remaining sugar is utilized in the synthesis of starch and stored in the various tissues of the plant.</em>

In snapdragon flowers, the allele for flower color shows incomplete

elixir [45]

Answer:To get the most pink flowers, a red and white rose plant must be mated. Red would have two red alleles--RR and white would have two white alleles--WW. In this cross, all of the offspring would inherit one red allele and one white allele-RW and would be 100 percent pink!
