SUBMIT
Answers
The correct answer is B. In the Northern Hemisphere, the polar jet stream separates colder air near the pole and warmer air to the south.
The jet stream is a geophysical effect caused by the large temperature difference between the north pole and the equator. Something similar also happens on a small scale. In summer, when night falls and the ground cools where the sun is gone, air blows from north to south across the boundary between warm and cold air. This is the refreshing evening breeze.
From the north, a jet stream generally supplies colder air than from the west or south. The jet stream also creates depressions with a warm front and a cold front.

Biochemists developed a compound that they hypothesize will disrupt the ability of the cells to organize centrioles and microtubules. This compound is applied to a group of onion root tip cells. What will serve as the best evidence that the biochemists' hypothesis about this compound is correct?
Answers
The best evidence that the biochemists' hypothesis about this compound is
correct will be lack of growth in the onions.
The centrioles and microtubules are important during the process of cell
division(mitosis) by organisms. They ensure that the cells divide properly
which helps cells to grow.
The compound being hypothesized to disrupting the activities of the
centrioles and microtubules means lack of growth will signify that it is

Hope its right :)
The difference between a producer and a consumer is producers convert sunlight energy into fuel and consumers cannot and producers can make their own food energy and consumers cannot. Thus, option B and D are correct.
Who is considered as producer?All green plants which prepares their own food is considered as the producers. Decomposers are usually defined as as those organisms which converts the complex organic matter into simpler ones, hence consuming the required amount needed and liberating the left over to the environment.
The cycle goes on and helps in maintaining a state of between the living and the decaying particles and the producers, consumers and the decomposers are interdependent on each other.Consumers convert sunlight energy into fuel and producers cannot.
So, it can be concluded that, after the death of an organism (consumer), some amount of energy is consumed by the decomposers and the remaining is mixed with the environment.
Therefore, The difference between a producer and a consumer is producers convert sunlight energy into fuel and consumers cannot and producers can make their own food energy and consumers cannot. Thus, option B and D are correct.
