Answer is letter B: prophase
Answer:
Meiosis involves two cell divisions
Explanation:
Mitosis and meiosis are two kinds of cell divisions and one of the main differences between the two is that meiosis goes through <u>2 nuclear divisions</u>.
Meiosis has Meiosis I and Meiosis II division. In Meiosis I, the number of chromosomes in the daughter cells are only half of the parent cells. This is why it is called a reduction division, because the chromosomes will be reduced by half. In Meiosis II, the daughter cells will have the same number of chromosomes as the parent cells, which in this case is the daughter cells of meiosis I.
Answer:
Yes.
Explanation:
The energy released in splitting just one atom is miniscule. However, when the nucleus is split under the right conditions, some stray neutrons are also released and these can then go on to split more atoms, releasing more energy and more neutrons, causing a chain reaction.
Answer:
Explanation:
The main goal of metabolism is for the ultimate release of energy. Energy is simply a function of the ability to do work. In this context, we consider energy in one of it forms, chemical energy.
The chemical energy obtained through digestion of food mostly in the form of glucose is the fuel for almost all of life's processes. This chemical form of energy serves as the power house for our functioning.
Energy is required by the brain to power it and carry out its function. Without energy being supplied to the brain, there won't be a living being.
Energy is needed for locomotion and other life activities. The muscles, bones and other appendages gets their coordination power from the energy released during metabolic processes.
It can be said that all life activities revolves round how organisms obtains and utilize energy.
Nutrients are the nourishment we derive from feeding. The nutrients helps to build our body parts e.g proteins. Energy are derieved from carbohydrates. Fats and oil are also energy sources and they help life functions. Vitamins and minerals supplies needed materials to make everyday life activities successful.
