Explanation:
From left to right, the oxides across period 3;
i) Period 3 oxides all appear white in colour. They are all crystalline solids and their melting points decrease from left to right.
ii) The volatility of period 3 oxides increases from left to right across the periodic table
iii) The metallic oxides on the right hand side adopt giant ionic structures. Silicon oxide which is in the middle of the period forms a giant covalent structure. Oxides of other elements towards the right hand side form molecular oxide structures.
iv) The acidity of oxides of period 3 increases from left to right. Metals on the left hand side form basic oxides while non-metals on the right hand side form acidic oxides. The oxide of aluminium in the middle is amphoteric.
v) The oxides of period 3 elements do not conduct electricity. However, the metallic oxides on the lefthand side conduct electricity in molten state. The non-metallic oxides on the right hand side are molecular hence they do not conduct electricity under any circumstance.

Answer:
The reactions of glycolysis occur in the cell's <u>cytoplasm</u>; the reactions of the citric acid cycle occur in the <u>mitochondria</u>.
Explanation:
<em><u>Explanations of some terms</u></em>
Glycolysis
Glycolysis takes place in the cytosol of the cell's cytoplasm. Glycolysis starts when glucose diffuses into a cell through the plasma membrane down its concentration gradient. Glycolysis is a metabolic pathway present in all organisms: from yeast to mammals that involves the oxidation of glucose molecules, the single most important organic fuel in plants, and animals to pyruvate with the generation of ATP (Adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide + hydrogen)
Citric acid cycle
Citric acid cycle also known as the Krebs cycle plays a major role in the process of energy production and biosynthesis as it oxidizes glucose derivatives, fatty acids and amino acids to carbon dioxide.
The presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.
The atmosphere has been divided into five layers based on the availability and the composition of different elements.
<h3>Troposphere</h3>
The troposphere has been the lowest layer of the atmosphere. It has been closed to the earth surface and provides with clouds and maintain weather.
The gases on the troposphere are used by the organisms for living purpose. The ozone has been a harmful gas for living organisms.
Thus, the presence of ozone in the troposphere has been considered as pollutant. Thus, option A is correct.

Answer:
The correct answer is A: Hypertonic solution
Explanation:
Syrup is a solution with a <u>high concentration of sugar</u>. When you put the fruit in this solution, the syrup concentration is higher than the sugar concentration inside the fruit, this is called an <u>hypertonic solution</u>. Consequently, there is a gradient of concentration between the interior of fruit cells and the exterior. The water will go out from the cells towards the exterior, in favor of the concentration gradient. In this way, you are removing water from inside the fruit (drying).
