Based on the explanation above, the best type of simple machine to use is an INCLINED PLANE. <em>Note that the essence of using a machine is simply to make our work easier and faster and also be able to overcome a much larger load with a minimal effort. </em>
Answer:
Independent assortment
Explanation:
The law of independent assortment says that genes for different traits or characteristics assort independently from each other during gamete formation. So each contrasting character's pair assort independently and do not show any association with the pair of other characters.
So after gamete formation collectively the gametes have all the possible combinations of alleles because all the genes are assorted independently in gametes.
This independent assortment of traits leads to some new combination of characteristics in the offspring. Therefore the correct answer is independent assortment.
Answer:
Muscles cells
Explanation:
Energy is required by all the cells but muscle cells more energy. As muscle cells help in body movement so they continuously contract and expand which requires a large amount of energy and this energy is provided by ATP.
Mitochondria are responsible for making ATP in the cells and the evidence that muscle cells require most ATP is the presence of more mitochondria in muscle cells than other body cells which helps muscle cells to provide more amount of ATP or energy.
Liver cells also contain a large number of mitochondria because they need energy for regeneration.
