The table shows the derived traits of five plant groups. Which trait was the earliest to appear among the plant groups ??

A. Flowers

B. Seeds

C. Stomata

D. Vasculature

C. Stomata

Explanation:

Over time, related groups diverge from a common ancestor through the process of evolution. Certain groups develop characteristics in response to specific environmental changes and become increasingly more genetically distinct.

These characteristics, called adaptations, ensure the survival of organisms and their offspring which best suit their surroundings. Through phylogeny, these changes are studied and mapped through genetic analysis in phylogenetics. Noting trends derived from the study of these groups, it can be seen that the most common traits are derived from a common ancestor.

In plants, stomata are regions that allow for gaseous exchange; they are seen in the most simple plant systems, where gases may readily diffuse through the cells of the organisms.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
