Answer:
Mitocondria is responsible for the reactions in cellular respiration.
Explanation:
Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients. Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes.
Answer:
hmm.......................
I think the correct answer would be the first option. The best method to use in order to measure the distance of star would be to calculate the variations in the position of the star due to movement of Earth in its orbit. The doppler shift which is what is being described in the last three options does not calculate the distance rather it calculates the relative velocity. The method used in measuring the distance was introduced by Edwin Hubble where he found that relative velocity of a body in space is directly proportional to the distance of that body from Earth.
These are just quickly written down, but I hope these can serve as sufficient answers.
Plant Behaviours:
1. - Some plants know when the sun will rise. Sunflowers are a good example of exhibiting this behavior called "Circadian Rhythm."
2. - Plants that have vines search for a surface, preferably a pole but walls are acceptable, to climb and grow on, which is called "Twining."
3. - Some plants 'curl up' whenever they are touched.
4. - Corn seeds can distinguish between 'up' and 'down,' which is called "Gravitropism."
5. - A plant can distinguish their own roots from another plant's.
Animal Behaviours:
1. - Animals can communicate, actually, they can communicate quite well! Dolphins and bees are infamous for this, as they communicate through a series of actions and the point comes across clear to others in their species.
2. - Body language is a behavior most commonly associated with animals, even though we do it too.
3. - Territorial/'Defensive' behaviors are common, such as marking and hostility when another animal trespasses into their domain.
4. - Certain behaviors are exhibited to attract/court mates, such as birds singing songs or chemicals being thrown off to lure in a partner.
5. - Cooperation is also a very common behavior, as seen in ants.
6. - Annual cycles, such as migration and hibernation.
7. - Animals also have a circadian rhythm like plants, which aids in whether or not an animal exhibits the behavior of being nocturnal.
