(a) coal. (b). Plastic. (c). graphite (d ) rubber​

Answer 1

Answer:

2 ) Mitochondria is an organelle which help in cellular respiration and production of energy

Answer 2

Answer:

Hi ! Let me help u with the answer.

Step-by-step explanation:

1. Ribosomes on the outer surface of the endoplasmic reticulum play an important role in protein synthesis within cells. Encyclopædia Britannica, Inc. The endoplasmic reticulum (ER) is a membranous organelle that shares part of its membrane with that of the nucleus.
2. Mitochondria : - Mitochondria are organelles whose membranes are specialized for aerobic respiration. The matrix of the mitochondria is the site of Krebs Cycle reactions. The electron transport chain and most ATP synthesis rely on the compartments created by the inner membrane of the mitochondria.
3. bromine
4. Non-metal which exist as a liquid at room temperature is bromine.
5. D) Graphite :- Graphite is an electrical conductor, hence useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.

I hope this answer helps you !!!
