Answer:
Chromatin helps regulate DNA replication.
Explanation:
Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
Answer: The observation clearly shows that certain behaviors are genetically controlled
Explanation:
From the observation, the Fishers bird uses long strip while the Peach-faced uses short strips and there offspring uses intermediate. It is an indication that the behavior of the length of strips cut by the bird is under genetic control and it can also be concluded that both the Fisher bird or Peach-face bird does not have complete dominance over length of strips cut for nest making.
Answer: Homeostasis is the cell membrane is a responsible for maintaining a stable internal environment
You cam calculate speed because it is equal with distance / period of time
Answer
Water molecules sticking to a mirror’s surface is an example of adhesion.
Explanation
Adhesion is the property of attractive force that exist between two different molecules. water molecules adhere to other surfaces due to their polar nature.
Importance
it is because of adhesive forces that water can travel and cover a distance of 100 meter up in the plants through xylem vessels as recorded in the world tallest tree (red wood tree)
