(a) The temperature goes up by 3⁰C.
(b) There is increase in temperature, so the reaction is exothermic.
(c) Examples of exothermic reaction include, rusting of Iron, burning of coal, reaction of strong acid and water.
(d) Examples of endothermic reaction include, melting solid salts and evaporating liquid water.

What is exothermic reaction?</h3>
Exothermic reaction is a type of chemical reaction in which energy is transferred to or from the surroundings.
Examples of exothermic reactions include the following;
- Rusting of Iron
- Burning of Coal
- Reaction of Strong Acid and Water
- Water and Calcium Chloride
<h3>What is endothermic reaction?</h3>
Endothermic reaction is a type of chemical reaction in which energy is absorbed from the surroundings.
Examples of endothermic reactions include the following;
- Melting solid salts.
- Evaporating liquid water, etc
<h3>Change in temperature</h3>
From the increase in temperature from 15⁰C to 23⁰C, we can conclude that the temperature goes up by 3⁰C.
20⁰C - 17⁰C = 23⁰ - 20⁰C = 3⁰C.
Since there is increase in temperature, the reaction is exothermic.

Answer:
Chemotherapy drugs and other toxins are actively pumped out of cancer cells by transmembrane proteins.
Explanation:
Drugs inside the cell can be inactivated by oxidation and / or conjugation with glutathione, such as glutathione S-transferases, playing an important role in detoxification. However, conjugation is not enough for drug elimination. And this is where the GS-X pumps appear. Transporter proteins, such as Mrp protein, act as GS-X pumps. The PgP, Mrp and Bcrp proteins function as expulsion pumps, thus reducing the intracellular accumulation of drugs, causing resistance in cancer cells.

Answer:
<em>The correct option is B) Tropical rain forest</em>
Explanation:
The tropical rain forest biome acquires four main characteristics:
1: Increased amounts of rainfall in a year
2: high average temperatures
3: soil that is not enriched with nutrients
4: increased level of biodiversity.
Extreme levels of biodiversity can be seen in the tropical rain forest biome. Hence, due to increased biodiversity, this biome has multistory communities. This biome contains about 50% of the world's known animal and plant species.
