Answer:
When starfish were removed from their environment, the species richness of that area went down. This was because the starfish ate the mussels, and when the starfish were removed, the mussels became abundant and preyed on many of the other species.
This experiment showed that the starfish were a keystone species. A keystone species is a species that has a low biomass but a large impact on the community they are living in.
Explanation:
New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust
The temperature in an autoclave must reach 121° C in order for sterilization to occur.
<h3>Sterilization using autoclaves</h3>
Autoclaves are used to wet-sterilize materials in the laboratory.
In order for the sterilization to be effective, the temperature of the autoclave must reach 121° C.
Also, substances to be sterilized must spend, at least, 30 minutes in the autoclave.

Answer:
1: Chemical Energy
2: Kinetic Energy
3: Electrical Energy
4: Mechanical Energy
Explanation:
1: The energy held in food is called <em>chemical energy. </em>It is a form of <u>potential energy</u> held within chemical bonds between atoms.
2: When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the <em>kinetic energy of flowing water</em> <u>as it moves downstream.</u>
3: The power for lights and stuff is <em>Electrical</em><em> </em><em>Energy</em><em>,</em> ofc :]
4: The <u>chemical energy in the food</u> gets changed into the <em>mechanical energy</em> of <u>moving muscles.</u>
