What allows us to develop a theory

You are studying mitosis in a species of snake. You notice that during mitosis of diploid cells there are 7 groups of chromosomes on the metaphase plate. Is it surprising that this is an odd number? Why or why not?

How does an ancestor population evolve into descendant species with differences in their shared structures

Which is not a disease contracted through contaminated water

Is it surprising that these genes would be of such similar lengths despite being from different species? Explain.

A substance when dissolved in water increases the H + ion concentration of the solution. Which type of solution is formed?

Fermentation occurs in a wide variety of organisms, including us. True False

True or false the ultimate source of energy for all living things is the leaf

If the relative ages of two formations are known, what else about them can be inferred

What is parthenogenesis? give an example

Calculate pH a decrease of one unit on the pH scale means a solution is ten times more acidic. a decrease of two units means the solution is 100 times more acidic. how much more acidic is acid precipitation (pH = 4.0) than pure water (PH = 7.0)
