The scheme of modern taxonomy goes:
Life > Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species
So, a PHYLUM is made of several classes.
Centrioles is only found in animal cells but not in plant cells.
The change in intractellular pH can potentially affect virtually all cellular processes. It includes metabolism, membrane potential, cell growth, movement of substance across of surface membrane, state of polymerization of the cytoskeleton and the ability to contract in muscle cell
Answer:
The correct answers are:
1. Greenhouse gases: Earth's heat is kept from going away.
Greenhouse gases, particularly CO2 and methane, have properties that allow them to trap heat in the atmosphere. This means that the more of these gases there are in the air, it will be hotter on Earth.
2. Chemicals released into the river—unfit for human consumption.
The chemicals released into rivers pollute the water, making it unfit for human consumption. There are only a few places in the world where there is enough freshwater to go around, so the fact that so many rivers have been poisoned is very worrying.
3. Excessive agricultural land use—forest fragmentation.
People cut down the trees so that there is more land that can be used for farming, As a result of this process, forests are being destroyed to the point of total devastation, and it is likely that this percentage will rise in the coming years as things continue.

Answer:
3 North poles and 3 South poles
Explanation:
A magnet is a piece of object that produces a magnetic field outside itself. A magnet has a north pole and a south pole. Similar poles repel each other, while opposite poles attract each other.
If a magnet of 10cm is broken into 3 pieces, we will have 3 pieces of magnet. Breaking a magnet does not destroy the properties of the magnet. Rather, each piece becomes a full magnet with both north and south poles.
Breaking a 10cm magnet will give us 3 magnets with 3 north and 3 south poles with equal pole strength.
