the number tells you the number of protons and electrons?
What is the Atomic Number
a change that alters the form or appearance of a material but does not make the material into another substance. Or a change that can easily be reversed.
What is Physical change

What is Amphibian
Something found in nature that enhances the lives of plants, animals and humans.
What are Resources
The first species to populate an area during Succession.
What is Pioneer species
How do you figure out the number of neutrons?
Subtract the atomic number from the atomic mass
What are the factors that affect the process of natural selection?
competition, genetic variations, environmental changes, and overproduction.
What is the original source of energy contained in coal?
All the energy contained in coal originates from the sun, through photosynthesis.
three examples of abiotic factors
Water, air, and soil, and sunligh
the process by which organisms that are best adapted to their environment are most likely to survive and reproduce.
What is Natural selection
How is the modern periodic table different from Mendeleev’s periodic table
Mendeleev’s periodic table is about the relation of properties of elements as dependent on the atomic weight of elements. Whereas the modern periodic table considers atomic number as the fundamental property that decides the properties of elements.
How does natural selection help species to evolve?
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success.
What are three different sources of freshwater on earth?
freshwater is stored in rivers, lakes, reservoirs, and creeks and streams.
the struggle between organisms to survive as they attempt to use the same limited resources in the same place at the same time.
What is competition
any change in the DNA of a gene or a chromosome.
What is Mutation
Which element has 42 as its atomic number?
Mo, Molybdenum
A mutation can be inherited only if it occurs in which type of cell?
Mutations are only passed on to offspring when they occur in germ cell DNA, which are the cells that create sperm or ova.
an unforeseen chain of events caused by a disturbance in the system.
what is Cascade effect
In order to survive, all living things need:
What is space, shelter, air (oxygen), food, and water
a long chain of molecules made up of repeating units
What is Polymer
What element is found in Group 6 and Period 4 on the periodic table?
Number 24/Cr/Chromium is an element found in group 6 and period 4, and has an atomic mass of 51.996.
how does reducing the temperature of a chemical reaction affect the rate of which it occurs?
When you lower the temperature, the molecules are slower and bump less. That temperature drop slows down how fast the reaction is happening.
