Correct Answer: C) nitrobacter

Explanation

This question is asking for the name of a bacterium that gets its energy from converting nitrites into nitrates. Nitrites and nitrates are both forms of nitrogen, which is an important element for living organisms. Bacteria play a vital role in the nitrogen cycle by converting different forms of nitrogen into usable forms for plants and other organisms. The correct answer to this question is option C: Nitrobacter. Nitrobacter is a type of bacteria that is involved in the process of nitrification, which is the conversion of ammonia and nitrites into nitrates. Nitrates are an important source of nitrogen for plants, which use them to synthesize proteins and other essential molecules. Nitrosomonas, option A, is also a type of bacteria involved in the nitrogen cycle, but it converts ammonia into nitrites instead of oxidizing nitrites into nitrates. Azotobacter, option B, is a type of bacteria that is capable of fixing nitrogen from the atmosphere into a usable form for plants. Escherichia coli, option D, is a type of bacteria that is commonly found in the intestines of humans and animals and is not directly involved in the nitrogen cycle. Understanding the roles of different types of bacteria in the nitrogen cycle is important for understanding how nitrogen moves through ecosystems and how it is made available to different organisms.

Correct Answer: A. a long-term loan

Correct Answer: C. (1, - \(\frac{3}{2}\))

Explanation

\(\frac{3x^2}{3} + \frac{3y^2}{3} - \frac{6x}{3} + \frac{9y}{3} - \frac{5}{3}\) = 0

2gx = -2x, 2 fy = 3y

g = -1, f = \(\frac{3}{2}\)

Centre (1, - \(\frac{3}{2}\))

Correct Answer: B. Aliko Dangote

Correct Answer: D. shading of crops

Correct Answer: D. 39

Explanation

The median is the middle number of the set, when it is listed in order from smallest to largest or vice versa. In this case we have an odd amount of numbers so we just count from each side until we find the number in the middle. 15,24,27,28,28,39,44,47,61,77,88 This gives us a final answer of 39 for the median.
