Answer:
A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions. By bringing the reactants closer together, chemical bonds may be weakened and reactions will proceed faster than without the catalyst.

When examining the groupings for life on Earth, a student lists six major groups, including archaebacteria, true bacteria, protists,
fungi, plants, and animals. The student wants to organize the groups by similar features. The student knows that plants are
autotrophic and can photosynthesize to make their own food. Which other groups can be organized into the group that is considered
autotrophs because they have some species that can photosynthesize? Select ALL that apply.
A
Fungi
B
Animals
Protists
D)
True bacteria
Archaebacteria
Autotrops are the organisms that can prepare their own food by process called photosynthesis. True bacteria and some archaebacterias are the one performing photosynthesis like plants.
What are archaebacteria?Archaebacteria are a group of microorganisms evolved separately from the bacteria and blue-green algae.
Archaebacteria can also survive in extreme environment. Examples include Halobacterium, Pyrolobus, etc.
Both archaebacteria and bacteria are able to photosynthesize their food.
Thus, correct option is D.

Students have a small steel ball and a large steel ball, and they have a short ramp and a tall ramp.
The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.
They do the following experiment:
**Written Response** What can they conclude from this experiment? Why?
Answer:
I think the height of the ramp affects the distance that the ball can go, but the size doesn't affect it
and as you decrease th height of the ramp it will look like straight thing, when it look like that the ball might need a little force in order to get speed also to go far
but in this condition the size can affect the ball distance it also depends on how much you give to it
Thank you !

The climate in this region is subarctic, characterized by a very cold, long and dry winter with temperatures reaching -50º C. Summer is short and humid, days are longer and temperatures can reach 20º C.
With this information, we can conclude that if you see reindeer, lynx, bear, and conifers, you are probably in a taiga.
