Answer: Active Transport

Explanation:

The movement of the particles across membrane needs energy. Energy is required in the condition where there is a movement of particles from a lower concentration to higher concentration.

It requires cellular energy for the movement of the particles. The larger molecules needs energy to move across concentration gradient.

Some inbred strains of the weedy plant Arabidopsis thaliana flower early in the growing season, but other strains flower at late
RoseWind [281]

Answer:

a. Let us consider that L is responsible for late and l is responsible for early. From the mentioned data, it can be concluded that allele L or late is dominant over early. By crossing plants 1 and 4 we get the expected ratio of 3: 1, which shows that it follows Mendel's law of dominant.  

b. The genotype of all the four plants are:  

1st plant = Ll

2nd plant = ll

3rd plant = LL

4th plant = Ll

c. If the plant 1 is self-fertilized then the expected progeny will be 3 (late): 1 (early).  

In case if the 2nd plant is self-fertilized, the expected progeny will be only early.  

In case if the 3rd plant is self-fertilized, the expected progeny will be only late.  

In case if the 4th plant is self-fertilized, the expected progeny will be 3 (late): 1 (early).
