Answer:
Evidence
Explanation: You would have more evidence to prove a point, which makes an idea valid.
Answer:
c) Both are functions of blood, that is, to carry oxygen to the cells and also remove wastes from the body.
Explanation:
Blood is a form of connective tissue and is made up of red blood cells, white blood cells, platelets and blood plasma. The red blood cells contains a metallo-protein structure known as hemoglobin. This hemoglobin binds to the oxygen and carry them to the cells and the tissues for proper functioning of them. The waste products like carbon dioxide is carried by the blood from the body tissues to expel it out from the body.
Matter can change from one state to another when thermal energy is absorbed or released. A great example is Ice having its state changed to the liquid that is WATER. When ice is heated, it absorbs thermal energy and its temperature rises. At some point, the temperature stops rising and the ice begins to change to water, a liquid. As we all know, The change from the solid state to the liquid state is called melting.
Since prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.
<h3>What are prokaryotic cells?</h3>
Prokaryotic cells are cells that are characterized by the absence of a nucleus or any other membrane-bound organelles.
On the other hand, eukaryotic cells have the presence of a membrane-bound nucleus that stores their genetic material.
Another important feature of prokaryotic cells is that they are haploid in nature i.e. they do not have chromosomes that occur in homologous pairs and have just one chromosome.
Therefore, it can be said that because prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.

Answer:
A
Explanation:
Coal is majorly used to produces electricity. The coal is ignited and the heat produced used to heat water to steam. The steam is then used to drive turbines with a dynamo effect to produce electricity. Turning off lights when not in use reduces the demand for electricity hence reducing the amount of coal needed to meet this demand.
Other ways to conserve energy is using bulbs with low energy demand - such as LEDs - and improving natural lighting indoors.
