Give reasons for the following.

1. Energy is often considered the “Fuel of Life”. Primarily, it is needed for maintaining basic

metabolism (maintenance energy). Any excess is then used for production of meat (growth)

and/or eggs (production). Fed too much energy, hens become overweight (excess growth)

leading to poor production. If fed too little energy, hens begin using protein to meet their basic

maintenance needs and egg production may be compromised. As is the case with most things

in life, balance is the key. This article is an attempt to provide a flock manager with some tools

to use when making decisions on feeding energy to a breeder flock. Some of the research

cited is not current and is in no way intended to be anything more than an example of the

thought processes that may be helpful when making difficult decisions about feeding.

Energy is essential to meet our most basic needs: cooking, boiling water, lighting and heating. It is also a prerequisite for good health – a reality that has been largely ignored by the world community.

2. Coal and diamond are two examples of carbon allotropes, where the carbon atoms are bonded together in different configurations. These structural differences result in very different material properties, such as hardness.

On its own, carbon cannot form diamonds under the surface of the Earth. Both coal and diamond are made primarily from carbon, but their chemical structures are significantly different. Coal is formed from highly impure carbon that often contains elements like oxygen, selenium, hydrogen, nitrogen and sulfur.

Use the principles of diffusion to explain why oxygen molecules in the tissues of the lung go into the blood
Keith_Richards [23]

Answer:

Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.

Explanation:

Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.

Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.

Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.

Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.
