imilar characters must be IGNORED.
-similar characters are derived
-similar characters evolved owing to convergent evolution
-similar characters evolved owing to gene flow
-similar characters are ancestral

Answer

similar characters evolved owing to convergent evolution; similar characters are ancestral

Explanation:

Convergent evolution happens when two organisms belonging to different species, living at different times or different continents but the same biome develop analogous structures hence making them appear similar.  The analogous structures were not present in the known ancestors of both groups.

Therefore convergent evolution is ignored during constructing phylogenies

Also similar characteristics that are ancestral are ignored.

-How do you think andioxidants can help cells perform their functions? -Why do plants have more antioxidants than humans? -Do yo
Vsevolod [243]

Answer:

Antioxidants help cells perform their functions against something called free radicals. Free radicals are molecules that happen to be produced when your body breaks down food and/or when you inhale or are exposed to tobacco products. These molecules play a role in leading to diseases such as; Heart disease and cancer. When plants synthesize, they collect many non-enzymatic Antioxidants like ascorbic acid and phenolic. Since plants have many more sites of ROS generation, Therefore, they could evolve more efficient non-enzymatic Antioxidant systems than humans because of their high intake and exposure to oxygen. (answer yourself about the structure in your own words using the information I gave you). Diet relates to both the function, structure and health of your cells. Having a balanced diet helps your cells to happily work and produce energy for your daily use. A balanced diet supplies your body with nutrients so it can work effectively. Without balanced nutrition, your body is way more prone to disease, fatigue, low performance and infections.

I hope this helped you!

Cells must be alive to use energy and do work dose passive transport occur in a cell that is dead? Why or why not?
Orlov [11]

Answer:

<h3>Yes, Passive transport can occur in dead cells.</h3>

Explanation:

For passive transport to occur, a concentration gradient has to be formed across a permeable or semi-permeable membrane. If the cell membrane of the dead cell, which is a semipermeable membrane, is intact and a concentration gradient has formed on both sides, passive transport can occur.

A concentration gradient is the difference in the concentration of solute molecules  across the membrane. Passive transport will allow solute molecules to travel from the higher concentration of the solute to the lower concentration across a membrane till equilibrium is reached, that is, both the sides of the membrane has equal concentration of the solute.

The transport of the solvent can occur as well, from higher concentration to lower concentration.

How may the height of a water table create a spring
yaroslaw [1]
When prolonged and excessive rainfall the more water percolates and the water table (below the earth surface/soil) rises.  The higher the water table the more the possibility increases for a spring to form in the sense that it would now be easier for the water to find a means of escaping the underground through perhaps a crack or a cave, etc.
