Answer:
Theories (scientific)explains a natural process, while Laws describe a natural process.
Generally, theories are usually supported by large evidences to explain and prove the natural processes.Scientific theory to be specific is used to elucidate nature to give vivid details for understanding.Thus theory provide basic understanding of the law under observation.
Therefore, law provides explanation of how the components of natural process are related to one another under the conditions which they are established in nature.
Explanation:
The answer is formation of spindle fibers.
Asters (Latin word for stars) of centrosomes are microtubules and are formed around centrosomes during mitosis. During prophase, asters and centrosomes move to the opposite sides of the cell. During metaphase, asters extend and connect to the centromere of chromosomes. During anaphase, those microtubules pull the chromatids apart to the centromeres on the opposite sides of the cell.
Explanation:
Isotopes:
₁₅³¹P and ₁₅³²P
Given parameters:
₁₅³¹P ₁₅³²P
Mass number = 31 32
Atomic number = 15 15
The two atoms are isotopes. Now let us derive numbers of their subatomic particles
₁₅³¹P ₁₅³²P
Protons 15 15
Electrons 15 15
Neutrons (31-15) = 16 (32-15) = 17
Because they are isotopes, they differ in the number of neutrons alone.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of their neutrons.
We clearly see that the mass number and number of neutrons pertaining to the atom differs. This makes them isotopes.

Answer:
Mechanical isolation
Explanation:
mechanical isolation is a form of prezygotic reproductive barrier, whereby similar species organisms become isolated and unable to successfully interbreed with each other to form zygote, as a result of incompatibility of their reproductive organ or structure, which prevents them from copulating. As a result of this, both species become separated as there is no gene flow between both.
The two species of juniper can be said to be kept separate by <em>mechanical isolation</em>, due to the differences and incompatibility of their reproductive structure.
The answer is an overhunting.
<span>The bottleneck event means drastic reduction of the population size because of environment changes. The consequence of this is the reduction of genetic variation. The bison population is a good example of the population bottleneck. The bison population drastically reduced its size due to overhunting which culminated at the end of the 19th century, when bisons almost extinct. </span>
