Answer:
B: volcanic activity
D: fossil fuel consumption
Explanation:
Fossil fuel consumption and volcanic activity are the two factors that has a great influenced on the global temperatures. Fossil fuel consumption is a human activity and volcanic activity both releases carbondioxide gas while burning. This carbondioxide gas is a greenhouse gas which block the reflected solar radiation and leads to increase in the surface temperature of the earth.
Answer: The concentration of the cytoplasm of red blood cells will be 0.5m.
Explanation: Red blood cells that are bathed in blood neither shrink nor swell and burst because the concentration of the surrounding blood is equal to the concentration inside the cytoplasm of the red blood cells. This means that the two solutions are isotonic. Since the two solutions are isotonic, there will not be movement of water molecules across the red blood cell membrane. Osmosis do not occur between two solutions of equal concentration, for osmosis to occur water molecules must move from a region of high water concentration to a region of low water concentration through a selectively permeable membrane.

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.
