Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

e) All of the answers are correct
Explanation:
The first X-ray picture of DNA taken in 1952 by Rosalind Franklin using the X-ray crystallography technique revealed the helical shape of DNA. Based on this discovery, it was discovered later on that the DNA molecule was made of two chains of nucleotides and at high humidity i.e when exposed to water it becomes long and thin.
For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive). ... If the acceleration is great, then the line slopes up steeply (i.e., the slope is great).
Answer:
the cell membrane is a cell structure that controls which substances can enter or leave the cell.
