Correct Answer: A. \(2(x^{2} - 1)\)

Explanation

\(f(x) = 2x^{2} - 3; g(x) = x + 1\)

\(g o f(x) = g (2x^{2} - 3)\)

= \( 2x^{2} - 3 + 1 = 2x^{2} - 2 = 2(x^{2} - 1)\)

Correct Answer: C. \(1111101_{two}\)

Explanation

\((101_{two})^3\) = \((5_{ten})^3\)

5\(^3\) = 125

And 125 = \(1111101_{two}\)

Correct Answer: B. Termite

Correct Answer: C) 8

Explanation

The question is asking how many points these goals were grouped into. The options given are 7, 6, 8 (which is the correct answer), and 9. This means that the MDGs were grouped into either 7, 6, 8, or 9 categories.

To answer the question, it is important to know that the MDGs were grouped into 8 categories or points. These points were to eradicate extreme poverty and hunger, achieve universal primary education, promote gender equality and empower women, reduce child mortality, improve maternal health, combat HIV/AIDS, malaria and other diseases, ensure environmental sustainability, and develop a global partnership for development.

Therefore, the correct answer to the question is option C, which states that the Millennium Development Goals were grouped into 8 points. It is important to note that the MDGs were replaced by the Sustainable Development Goals (SDGs) in 2015, which are a set of 17 goals to be achieved by 2030.

Correct Answer: A. factors of production

Explanation

(a)Adaptation: These are special features/characteristics that an organism possesses, which enable it to live/ survive successfully in an environment

(b)(i) Aloe: -

• The succulent leaves are adaptations for water storage.
• They are also adapted for surviving high temperatures and drought.

(ii)Cactus: Stems are thick and succulent for water storage, while leaves are reduced to conserve water, by reducing rate of transpiration.

(iii)Fowl: The beak is short/ strong/straight for picking insects/seeds, earthworms/small pieces of food, pecking of feathers.

(iv)Fish: The dorsal side is dark while the ventral side is silvery/counter shading. - This dual coloration protects the fish from predators, looking at them from above and below the water.

(v)Pines: The needle like leaves reduce water loss by transpiration. - Also conserves water for use in the long dry season.

(c)(i) Population: This is the total number of individuals of the same species, living together in a habitat, at a given time.

(ii) Effects of over population: -

• Competition for limited resources.
• Predation/cannibalism.
• Spread of diseases.
• Food shortage.
• build up toxic waste in the environment.
• Limited space for individual dwellings.
• High mortality/mortality rate.
• Increase of social vices/behaviour.

Correct Answer: C. Economic interest

Correct Answer: D. adding up the total variable cost and total fixed cost

Correct Answer: C) hepatic portal vein

Explanation

The question is asking about the blood vessel that carries blood from the alimentary canal to the liver. The options are hepatic artery, hepatic vein, hepatic portal vein, mesenteric, and hepatic mesentenism. Out of these options, the correct answer is the hepatic portal vein. This vein is responsible for carrying nutrient-rich blood from the small intestine and stomach to the liver. The liver then processes the nutrients and removes any harmful substances from the blood before it is sent to the rest of the body. It is important to note that the hepatic artery and hepatic vein are also important blood vessels in the liver, but they carry oxygen-rich blood to and from the liver, respectively. The mesenteric blood vessels are responsible for carrying blood to and from the intestines, while hepatic mesentenism is not a valid term in biology. Understanding the role of the hepatic portal vein is important in understanding how the digestive system and liver work together to maintain the body's health.

Correct Answer: A. Education and training
