Due to collisions between particles in the spinning cloud, the solar nebula begins to flatten. The particles in the gas cloud first have all different speeds in different directions. As they start colliding with each other, their final velocity is the average of the two initial velocities before collision.
All plant and animal groups existing together and the physical factors with which they interact compose an ecosystem<span>.</span>
Hey there!
Number 3, "has more people than ever before" is correct. As there are more people, there is a greater need more resources.
Hope this helped, have a good night!
Answer:
A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus. The word prokaryote comes from the Greek πρό and κάρυον. In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota.Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals. These organisms are grouped into the biological domain Eukaryota.
Explanation:
Increased atmospheric carbon dioxide will diffuse to the ocean water (since normally, there is lower concentration of dissolved carbon dioxide in the ocean water). The dissolved carbon dioxide takes into the form of carbonic acid thereby increasing acidity of ocean water. More often than not, the acidification of ocean water leads to detrimental results especially in marine organisms that are pH sensitive such as coral reefs and many invertebrates.
