Answer:
d) 625 grey wolves
Explanation:
Number of grey wolves in yellowstone;
1997 = 100 wolves
2002 = 275 wolves
Between 1997 and 2002 (a five year period), number of wolves increased by; 275 - 100 = 175 wolves
Population growth rate between 1997 and 2002 = 175 wolves per 5 years
Note that the population growth continued at the same rate from 2002 to 2012 (a ten year period).
Therefore;
if; 5 years = 175 wolves
10 years = (175 × 10) / 5 =350 wolves.
therefore, number of wolves between 2002 and 2012 = 350 wolves.
Number of wolves as at 2002 = 275 wolves
total number of wolves at 2012 = 350 + 275 = 625 wolves
A benefit of the carbon cycle is that it is critical to the food chain. The carbon cycle is important to all ecosystems as well as the food chain.
Carbon is an important element in living tissues and in all organic matter. All living things are made of carbon.
Plants use carbon from carbon dioxide gas in the atmosphere to make their own food and to grow. The carbon becomes part of the plant. Plants are consumed by animals. Thus the carbon cycle plays a vital role in the food chain.

Answer:
The correct answer will be option-Cochlear nucleus
Explanation:
Cochlear nucleus is the centre of the neurons called nucleus where the cochlear nerves or auditory nerves bring the information from the inner ear cochlea.
The cochlear nucleus is composed of two nucleus- ventral cochlear nucleus (unlayered) and dorsal cochlear nucleus( layered).
The auditory nerves bring the information to the ventral cochlear nucleus and then to the dorsal nucleus where the nucleus processes the information.
Thus, the cochlear nucleus is the correct answer.
Arterial blood pressure is the volume of the blood entering the arteries, or veins. It's controlled by the kidney and when there's too much liquid, it rises, and when there's too little liquid, it drops. Sorry if this doesn't help, but I hope it does.
