Muscle cells in our heart are constantly working. which of the following organelles would they have in larger quantities than other cells in the body?
a) vacuoles
b) mitochondria
c) chloroplasts
d) nucleoli

The correct answer will be option B.

Explanation:

Mitochondria are the double-membrane organelles present in eukaryotic cells which helps in generation of the energy currency that is ATP of a cell.

Mitochondria provide a site for the generation of these ATP molecules, the reason they are known as the kitchen of the cell.  Their number in a cell depends on the function of the cell as if a cell is involved in function which need more ATP will have more mitochondria and if not will have few mitochondria.

Since a cardiac muscle cell needs more energy to pump blood from one chamber to another and to body, therefore, cells will have more mitochondria and thus, option B is the correct answer.

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
