Answer:
Refer to the attached image for correct labeling.
Explanation:
- The diagram is of a plant cell and its organelles.
- The nucleus houses the genetic material and controls all life processes.
- A plant cell contains one large vacuole in the center that stores water and nutrients.
- Chloroplast is the site for photosynthesis. It captures light and utilizes it and carbondioxide to produce glucose.
- Mitochondria are called the power house of the cell. Through a process called cellular respiration, they break down the glucose produced in photosynthesis into energy compounds such as ATP as well as oxygen and water.
- The endoplasmic reticulum is the site for protein sysnthesis. It contains two parts: the rough endoplasmic reticulum (RER) which contains ribosomes that synthesize proteins and the smooth endoplasmic reticulum (SER) which packages the proteins into transport vesicles.
- The nucleus contains the nucleolus that is the site for ribosome assembly.
- The cell membrane is a semi-permeable membrane that covers the cell and controls cellular transport.
- The cell wall is a hard, outer covering that protects the cell and maintains its structure and shape.

Answer:
c) The organism would be less active because everything loses energy when it’s too cold.
Explanation:
Global warming / climate change resulting in the melting of glaciers causing a rise in sea level.
Answer:
"Action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern."
It is the mode through which a neuron transports electrical signals.
Explanation:
- Option - (a) is the best choice to choose from,
- <u>The refractory period :</u>
A second action potential cannot occur until the membrane has recovered or reestablished, this is the refractory period. The absolute refractory period coincides with inactivation of voltage-gated sodium channels which makes it impossible to generate another nerve impulse.
