Answer:
"A mineral is a homogeneous (which means composed of parts or elements that are all of the same kind) naturally occurring substance with a definite but not necessarily fixed chemical composition.

Answer:
The somatic cells of fruit flies contain eight chromosomes, which means they have two sets of four chromosomes. Meiosis is the process by which sex cells are produced. Sex cells are haploid, which means they have one set of chromosomes.
Explanation:
The activation energy of the reaction without an enzyme is represented as X.
<h3>What is activation energy of a reaction?</h3>
Activation energy of a reaction is the minimum energy that reactant molecules must possess in order to effectively collide to form products,
The activation energy of a reaction depends on the bond energies of the reactants.
Given an energy profile diagram, the activation energy is represented as EA.
In the diagram, the activation of the reaction without an enzyme is X because it the activation energy of an uncatalyzed reaction is greater than the activation energy of a catalyzed reaction.
In conclusion, activation energy is greater for an uncatalyzed reaction.

Answer:
Explanation:
. Natural selection is a pressure that causes groups of organisms to change over time. Animals inherit their genetics from their parents or ancestors, and the environment is constantly changing. So, no organism is perfectly adapted to its environment.
Answer:
Explanation:
Stem cells have the ability to divide through mitosis through meiosis through mitosis and produce unspecified cells.
They can be developed into a required tissue because of their ability of differentiation DNA replication reproduction.
