Answer:
Excessive nutrients from fertilizer run off.
Explanation:
Scientists have suspected that phytoplankton blooms might be connected to agricultural run-off. They got some evidence from a recent study by comparing the timing of irrigation along the west coast of Mexico and phytoplankton blooms in Mexico’s Sea of Cortez. During the comparison, they had found a close correlation. Phytoplankton blooms occurred in the Sea of Cortez shortly after the irrigation. This happened because of carried fertilizers after irrigation and other agricultural run-offs into the sea.
The bloom detected in the Gulf of Mexico on December 13 might be similarly linked to agricultural run-off.
When an ion or a molecule passes through a membrane without something facilitating, or encouraging that passage, such as a protein does. What drives it is the force of the diffusion itself instead.

Answer:
It is maternal inheritance (cytoplasmic inheritance) of the gene for petal color.
Explanation:
In the given experiment, the color of the petal is regulated by maternal inheritance. In the first step, the true-breeding pale plant was pollinated by a true-breeding normal plant, therefore, all the F1 was identical in terms of petal color to the female plant (the true breeding pale plant).
In the second step, the F1 pale plants were pollinated by the true breeding normal plant. Again, the petal color in the progeny was determined that the female parent (the F1 pale plant). If true breeding normal plants will be pollinated by true breeding or F1 pale plant, the progeny will exhibit "normal phenotype" for petal color since the female plant has normal phenotype here.
