Hi there!
a. Talisa should only choose one type of material to work with to do the experiment (either pine boards or oak boards).
b. She should make this change because it will set a restricted variable. In other words, the experiment would be more accurate if the different types of glue were tested similar conditions.
Hope this helps!

Explanation:
Answer: Atomic masses increase as the atomic numbers increase.
Explanation: Elements are arranged in the periodic table in increasing order of their atomic numbers. A periodic table is a table showing the arrangement of the elements in the increasing order of their atomic numbers. Atomic number of an element is the number of protons in the nucleus of an atom while atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom.
Atomic number of elements increases across the period from left to right and increases down the group and the atomic masses of the elements increase from left to right across the period and down the group as the atomic number increases.
All of them will be red and long stemmed if red and long stem are both dominant traits. If not they will all be short stemmed.
