The correct answer is option (A) Variation in the strawberry plants.
When the effect of fertilizer on the growth of two strawberry plants is tested, unavoidable source of experimental error is the variation in the strawberry plants. Variation refers to the deviation or differences from the normal plant which can be due to genetic variation. It is due to change in the DNA sequence. If any one of the two plants being tested show variation, the rate of metabolism differs and changes the growth pattern of the plant. The rate of absorption of water and nutrients is effected which brings change in the growth of the plant and causes an error in the experiment and the result.
The organelle inside the cell that eliminates waste is the lysosome. It contains chemicals that help digest food and worn-out cell parts. <span>When nutrients enter the cell, lysosomes release digestive enzymes to break down the nutrients. If the cell isn't getting enough food, lysosomes will digest other organelles so that the cell does not starve. Lysosomes eliminate worn-out organelles from the cell via the process of autophagy.</span>
