Centrioles is only found in animal cells but not in plant cells.
Explanation:
To swim, they move their tails up and down, rather than back and forth as fishes do. This is because whales evolved from walking land mammals whose backbones did not naturally bend side to side, but up and down. ... Whales do the same thing as they swim, showing their ancient terrestrial heritage.

Some of the carbon atoms in the glucose exit the leaf as carbon dioxide during respiration while other carbon atoms are used to make important parts of the plant, such as additional leaves or wood. Carbon atoms that remain in leaves will either fall off (during plant senescence) or become a meal for an animal. Hope this helps
Respiratory system= breathing system
To keep our Respiratory system healthy we should:
1- never breathe in front of polluted areas
2- never pollute our areas
3- try to make our environment normal
Answer:
Somatic vs Germline Mutations. ... Somatic mutations – occur in a single body cell and cannot be inherited (only tissues derived from mutated cell are affected) Germline mutations – occur in gametes and can be passed onto offspring (every cell in the entire organism will be affected)
