Answer:
Cool dense water sinks to the ocean floor.
Warm water replaces cool surface water.
Wind blowing parallel to the shore causes upwelling of cool water.
The <span>eukaryotic cells do not contain any organelles such a nucleus in particular. The difference in their structures for prokaryotes and eukaryotes will also include the presence of chloroplasts and mitochondria. Also, structures such as cell wall and chromosomal DNA structures are also some of the difference in the two types of cells. The answer to the second question is C.

</span>
- 19. Plant cell have plastids - chromoplasts, chloroplasts, leucoplasts.
- 20. Animal cell do not have a cell wall. Its outermost covering is the cell membrane.
- 21. Plant cell do not have centrosomes.
- 22. Animal cell has cholesterol in the cell membrane.
- 23. Either vacuoles are absent or present in small.
- 24. Plant cell has chloroplast.
- 25. Storage material is starch for plant cell.

<span>I found the exercise on the internet. Attached is a pic of the diagram.
Correct answer:
"All collisions between particles are perfectly elastic."
This is called elastic collision. Elastic collision is the </span><span>encounter between two molecules where the total </span>kinetic energy<span> of the molecules before the encounter is equal to their total kinetic energy after. The perfectly elastic collision it only happens, though, when the kinetic energy is not transformed into other forms of energy.</span>
Beacuse men only have one X chromosome so beacuse colourblindness is found on the X chromosome then if the X inherited from his mother contains the allele for colourblind then he will be colourblind. women have two X chromosomes so even if they inherit one colourblind allele then if the other X contains a normal vision allele then they will be able to see normally.
