Mitosis is the process, in the cell cycle, by which a cell duplicates into two genetically alike daughter cells.

How many types of renewable energy are there normally said to be?
Seven: solar, wind, hydro, biomass, waves, tidal, deep geothermal.

What is a Magnetic Field?
A magnet has two poles, called North and South.
A magnetic field is a region around the magnet
where magnetic materials experience a force.
There are only three magnetic elements. They are
iron, nickel and cobalt. In practice you will
only use iron, or steel which is an alloy of Iron.

What is a chemical reaction?
A chemical reaction is the change of a substance into a new one that has a different identity.
100
What is a Physical Change
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.

What is a meiotic cell
Meiosis is a special type of cell division necessary for sexual reproduction in Eukaryotas, such as animals, plants and fungi.

Why is solar sometimes termed the primary renewable energy?
Because it is the origin of many other energies as explained above. It is the most abundant renewable energy resource. Converting it into other forms is inefficient. Solar panels rarely exceed 50% efficiency over a year. Photosynthesis is typically under 1% efficient over a year.

How can you tell if it is occurring.
A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Absolute confirmation of a chemical change can only be validated by chemical analysis of the products

What is a Physical Property
A physical property is any property that is measurable whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its transformations or evolutions between its momentary states.

What are the differences between Mitosis and Meiosis?
In mitosis one single division of the mother cell results in two daughter cells while in meiosis two division of the mother cell usually result in four meiotic products.

What is solar thermal electricity?
What is Solar technologies which usually heat water which then drives steam turbines to generate electricity.

Does a magnetic have a magnetic field
Yes or No
yes

What are Chemical Reactions described as?
Chemical Equations

What is a Element?
A part or aspect of something abstract, especially one that is essential or characteristic.
400
Before a cell divides, what happens to the
genetic information in that cell?
Before a cell divides, the genetic
information in that cell is duplicated

What types of biofuels are there?
What is Biosolids, more commonly known as biomass, bioliquids, biogas. These are the three phases of matter!
400
Does Jupiter have a magnetic field.
Yes Or No
Yes Jupiter has a large, complex, and intense magnetic field that is thought to arise from electrical currents in the rapidly spinning metallic hydrogen interior.

What are Chemical Bonds.
A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms
400
What is a Molecule?
A group of Atoms Bonded together.

The duck-billed platypus has 52
chromosomes in its body cells. When the
platypus's body cells divide by mitosis, how
many chromosomes will each daughter cell
have?
Body cells undergo a type of division called
mitosis. During mitosis, the daughter cells
produced are identical to the parent cell.
So, daughter cells resulting from mitosis in
a duck-billed platypus will have 52
chromosomes.

What are photovoltaics?
What is Technologies which converts solar radiation directly into electricity.

What is Earth's Magnetic Field known as.
Geomagnetic Field

What is a Chemical Change.
Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances
500
What is a Compound?
A thing that is composed of two or more separate elements a mixture.
