Answer: Leeuwenhoek biggest contribution is to the first tenet of the cell theory.
Explanation: the first tenet of cell theory states that every living being is made of cells and even an organism can be made of just one cell able to reproduce by itself.
Leeuwenhoek observations stablish the existence of microscopic structures alive some with movement. This helped other scientists to determinate this structures were cells that can make vital processes such as feeding, breathing or reproducing which are determinant in biological definition of life.
Answer: Nucleus membrane isn't part of the ER or Golgi Apparatus, BUT all of them are part of the endomembrane system.
Endoplasmic reticulum and Golgi apparatus are two membrane-bound organelles found in eukaryotes. Both these organelles are closely associated and functionally related. Both endoplasmic reticulum (ER) and Golgi apparatus are two components of the endomembrane system of a cell. Lysosomes and vesicals are the other components of the endomembrane system.
The DNA controls the characteristics of an organism. I

Answer:
The correct answer is - option C.
Explanation:
The case in this the biological exterminators asks to use the biological concept which includes spraying the solution of the juvenile hormone to get rid of nymphs of specific insect and according to the assumption, this solution causes some alteration on the ability to reproduce of such nymphs and leads to only nonreproductive ones.
On the given condition the increasing of nymphs, the number of adult nymphs or decreasing of nymphs can not be condition and as the reproductive ability is affected the number of nymphs would be the same.
Thus, the correct answer would be - option C.
