<h3><u>Answer;</u></h3>
A. <em>18 hydrogen atoms </em>
<h3><u>Explanation;</u></h3>
- <em><u>Alkanes are group of hydrocarbon that are saturated</u></em>. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
- <em><u>The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.</u></em>
- Therefore,<u><em> an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. </em></u>Thus, the formula of the hyrocarbon will be; C₈H₁₈.
Answer:
If two breaks occur in one chromosome, sometimes the region between the breaks rotates 180 degrees before rejoining with the two end fragments. Such an event creates a chromosomal mutation called an inversion.
Explanation:
The rate of photosynthesis increases withe increase in temperature. Photosynthesis like any other chemical reaction responds positively to an increase in temperature.
At high temperatures, enzymes that takes part in the photosynthesis can be destroyed. This is 20°C where enzymes are usually denatured.
- Photosynthesis is the process where green plants manufacture their food using inorganic substances from the environment.
- During photosynthesis, plants combines carbon dioxide with water and produces organic molecules and oxygen.
- Like any other chemical reaction, the reaction will proceed faster with an increase in temperature.
Hypothesis: If temperature is increased then the rate of evolution of oxygen gas increases because the rate of chemical reactions increases with increase in temperature.
Since oxygen is a by product of photosynthesis, we can quantify its rate of production as temperature increases.

Answer:
A
Explanation:
The correct answer here would be that <u>less than 3 percent of Earth's water is freshwater containing no salt.</u>
<em>Generally speaking, about 71 % of the earth is made up of water. Out of this percentage, approximately 97 % is found in the oceans with less than 3 % being freshwater. About 68.7 % of the freshwater is locked-up as glacier and ice, 30.1 % is groundwater, while the remaining 1.2 % represents surface and other forms of freshwaters which include ground ice and permafrost, lakes, atmosphere, rivers, swamps and marshes, soil moisture, and the freshwater in living organisms. </em>
The correct option is A.
Answer:
Explanation: Replication is a semiconsecutive process this means that the strands of the DNA molecule separate to form two separate templates which will then combine with nucleotides following the complementarity base sequence to form two new daughter DNA
