Answer:
The correct answer is option D. Light and some other factors are necessary for chlorophyll production
Explanation:
By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.
Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.

Answer:
Cells and tissue
Explanation:
Cells are the most basic unit of life made up of several organelles that perform various functions which enables the cell to exist.
An aggregation of cells is called a tissue. The bone is composed of several interconnected cells and tissues.
A bone heals when bone cells and tissues are gradually repaired. Hence, the most basic levels of organization involved when a bone heals are cells and tissues.
Answer:
jet streams form when warm air masses meet cold air masses in the atmosphere
It modifies and packages proteins and lipids made within the cell, and sends them out to where they are needed. The cell's endoplasmic reticulum (ER) generates biological raw materials, packaging them in membrane-enclosed bubbles called vesicles, for transport to the Golgi.
