Answer:
chemical and physical changes
Step 3
Explanation:
Step 3 contains a major error.
In step 3, it is stated as molten rocks are heated.
Molten rocks are not heated.
Solid rocks are heated as the plate is pushed down under the earth due to movement of tectonic plates.
When the rock is heated, the rock is melted to become molten.
- The molten rock is called magma.
- When the magma cools, it solidifies to form igneous rocks.
A molten rock is not heated to form igneous rocks.

Answer:
A) All the elements are composed of atoms.
d) Atoms cannot be created or destroyed in any chemical changes.
c) An atom of one element cannot be changed into an atom of a different element.
Explanation:
The main postulates of Dalton atomic theory was:
1) The matter is composed of atoms and atom is indivisible particle which can not be destroyed.
2) The atoms of an element are identical.
3) The atoms of different elements are combining with definite proportion and form compounds.
4) The atoms of different elements are different from each other.
5) During chemical reaction rearrangement of atoms occur and form new compounds.
1. Hybridization is a method of sexual reproduction whereas cloning is a method of asexual reproduction.
2. Hybrid animals are sterile, but cloned animals are fertile.
3. Hybrid organisms contain DNA from both male and female parents but cloned organisms contain DNA from only one type of parent.
4. Hybrid has superior character over its parents (improved hybrid vigor) but clones are 100% identical to their parent.
5. Hybridization gives only one hybrid progeny, whereas through cloning unlimited identical organisms can be produced.
Answer:
B. 1.000 × 10-4 kg
Explanation:
A. 1.000 × 10-8 Mg = 0.00000001 Mg = 0.1 mg
B. 0.0001 kg = 0.1 g
C. 1000 ug = 1 mg
D. 1
.000 × 10-2 cg = 0.01 cg = 0.1 mg
A = D
B > C > A = D
