Answer:
the second one
Explanation: IN the text it literally states it explicitly.
1.Gravity caused the disk-shaped nebula to shrink.
<span> A cloud of gas and dust started to shrink or more corectly started condensate, due to the force of its own gravity. This process started slow, but increased in velocity as more material were moving toward the center.</span>
2.<span>Rotational motion caused the nebula to flatten out in its disk-like shape.</span> The nebula spined counterclockwise to conserve the angular momentum of the material of the material that were going to the center. This rotation, made the materials that were not in the center flatten out, that's why it looks like a disk.
Answer:
2.Less than 73% of the populations would have only one allele present.
Explanation:
The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.
Using a larger breeding population would not be expected to alter the outcome of the experiment.
<h2>Dinoflagellates thrive in bahia fosforescente</h2>
Explanation:
- Dinoflagellate, are one-celled aquatic organisms having two dissimilar flagella.
- It has a characteristics of both plants and animals.
- Most of the dinoflagellates are marine, but some live in freshwater habitats.
- Bahia fosforescente is one of the phosphorescent bays where millions of glowing marine dwellers such as dinoflagellates cause the lake to glow a bright blue in night.
- Dinoflagellates has the characteristics of Bioluminescence which they use it as a defense mechanism.
- During night, due to the bioluminescence of dinoflagellates,water can have an appearance of sparkling light.
- Dinoflagellates takes their nutrients from marine organisms, thus they grow or develop well in bahia fosforescente.
Anatomical and molecular features often fit a similar pattern due to Homology. Homology is the existence of shared ancestry between two structures or genes in a different species.
A process that can cause this not to be the case is Convergent Evolution.
Convergent Evolution occurs when two unrelated species independently evolve similar traits to cope with evolutionary changes.
