Answer:
nucleus, ribosomes
Explanation:
DNA, and the instructions that are used for making proteins are all found in the nucleus. The nucleus witholds the majority of the cell's genetic material. Ribosomes do protein synthesis and are located on the rough endoplasmic reticulum.
Flowering plants have flowers that allow for easy pollination via wind or animals. These plants are also able to disperse their seeds, using the wind to help carry the seeds away. Both processes are critical for reproduction.
HAHAHA, LOL

Answer: The correct answer is D) The number of chromosomes remains the same in mitosis and is reduced by half in meiosis.
Explanation-
Mitosis and meiosis are the two forms of cell division. Mitosis occurs in all the living organisms. In mitosis, cell divides into two daughter, each having equal number of chromosomes with that of the parental cell. It is also a process of asexual reproduction.
Whereas, meiosis typically occurs in sexually reproducing organisms during gamete formation. In this process, the number of chromosomes are reduced to half as the homologous chromosomes are separated.
Thus, the number of chromosomes remains the same in mitosis and it is reduced by half in meiosis.
