There are 6 common types of pesticide that are recognized and seen quite often:
1. Insecticides which are mainly used to kill insects, ticks, and mites.
2. Herbicides which are mainly used to kill weeds.
3. Fungicides which are mainly used to kill mildew and other fungi.
4. Rodenticides which are mainly used to kill mice, rats, and other rodents.
5. Disinfectants which are mainly used to kill bacteria and mold.
6. Wood Preservatives which mainly protects wood from fungus and insects invading it's system.

Answer:
The correct answer is it occurs naturally by diffusion.
Explanation:
Diffusion is one of the most important passive transport mechanism which helps in the movement of small molecules and gases across the plasma membrane down their concentration gradient.
In simple words diffusion deals with the transport of small molecules and gases from the region of high concentration to the low concentration region untill the contration of both the regions become equal.

Answer:
Two pea plants are crossed, both are with yellow color, offspring produced are 25% with green peas, while remaining 75% are with yellow peas. It clearly describes that yellow pea color is dominant while green is recessive one.
According to the given data, the ratio of both pea colors is 3:1 of yellow to green color. According to Mendel's law of inheritance, it is only possible when both the parents are heterozygous for the pea genotype. Let the genotype for yellow color be 'Y' and that for green color is 'y'. So, the genotype of both parents would be "Yy", they will fuse to form offspring having 25% green and 75% yellow phenotype of pea color.
