Answer: If one is constructing a phylogeny of reptiles using DNA sequence data of birds, mammals, amphibians or fish, the suitable outgroup to be used are mammals due to the time of divergence from other group of organisms.
Explanation: Phylogeny is used to determine evolutionary relationship between items or organisms. A phylogenetic tree is a graphical illustration of phylogenetic relationship. In phylogeny, an outgroup represent an organism that is more distantly related to other group of organisms.
In a phylogenetic tree, outgroup stands alone. It shows that the time of divergence of that particular organism is far from other group of organisms. Outgroup is used to root a tree and sometimes represent a group that is more ancestral on a tree.
It should be noted that differences in the DNA sequences of the organisms under consideration will determine which organism will serve as the outgroup.
D CHLOROPHYAT NOT THE OTHER ONES
Answer:
True
Explanation:
The deep parts of an ocean receive minimal or no sunlight. Hence, the survival of phototropic organisms like plants and algae is impossible or minimal here. Hence, there is a very little diversity in deep oceans. The organisms living here have to feed on dead decaying matter or on each other for survival. Mostly, the organisms living here use dead organisms as food. No other food source is available here.
The answer to the question stated above is: letter C.Traits acquired during a lifetime are not passed on to offspring.
>Lamark had doubts too. He cited the animal's neck as an example. He said that animal's neck<span> could get a bit longer when its owner often stretched it, trying to reach higher leaves in the trees for example. But, t</span>hat's actually not stretching. The truth was too far beyond belief.
However, merely because a physical change has been achieved by an individual, it doesn't mean that those changes can be inherited by their descendants.
