Converting it into an alloy.

The upper layer of earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains, clay, and rock particles.

Wool is the textile fiber.Wool is the hair of certain mammals. Most wool comes from sheep and goats, but wool is also taken from camelids (camels, llamas, etc.) and special rabbits. Wool is a natural material.

An oscillation can be a periodic motion that repeats itself in a regular cycle, such as a sine wave, the side-to-side swing of a pendulum, or the up-and-down motion of a spring with a weight

The word Heterotrophic is the combination of two words i.e. Hetero + Trophos. Hetero means ‘others’ and ‘trophos’ means nourishment. If organisms depend on others for their food, it is called the Hetetrophic Nutrition.

Animals cannot make their food themselves. They depend for food upon plants.Humen indirectly depend on plants  Therefore they are known as Heterotrophs.

A concentrated acid is an acid which is in either pure form or has a high concentration. Laboratory type sulphuric acid (about 98% by weight) is a concentrated (and strong) acid.
Conc acids have a much higher concentration of H+ ions per unit volume.

A dilute acid is that in which the concentration of the water mixed in the acid is higher than the concentration of the acid itself. For instance, 5% sulphuric acid is a dilute acid.
Dilute acids have a lower concentration of H+ ions per unit volume.
 

Cell is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life that can replicate independently, and cells are often called the "building blocks of life".

Partial Parasites : Those parasites which depend only for food on the host are called partial parasites.For example, mosquito, lice etc.

Some examples of autotrophs include plants, algae, and even some bacteria.

autotrophs often make their own food by using sunlight, carbon dioxide, and water to form sugars which they can use for energy. Some examples of autotrophs include plants, algae, and even some bacteria. Autotrophs are important because they are a food source for heterotrophs (consumers).

Assimilation is the combination of two processes to supply cells with nutrients. The first is the process of absorbing vitamins, minerals, and other chemicals from food within the gastrointestinal tract.

Assimilation in biology is the process through which an organism incorporates nutrients from outside its body to the more complex structures needed inside of it.

The two most common forms for iron are Fe(II), in which the iron ion shares two of its electrons, and Fe(III), in which it shares three electrons.The chemistry of iron is dominated by the +2 and +3 oxidation states i.e. iron(II) and iron(III) complexes e.g.  Fe^{<font size="2">2+</font>}  and Fe^{<font size="2">3+</font>}

Blood plays an important role in regulating the body's systems and maintaining homeostasis. It performs many functions within the body, including:

1. Supplying oxygen to tissues (bound to hemoglobin, which is carried in red cells)
2. Supplying nutrients such as glucose, amino acids, and fatty acids either dissolved in the blood or bound to plasma proteins (e.g., blood lipids)
3. Removing waste such as carbon dioxide, urea, and lactic acid Immunological functions, including circulation of white blood cells and detection of foreign material by antibodies
4. Coagulation, which is one part of the body's self-repair mechanism (blood clotting by the platelets after an open wound in order to stop bleeding)
5. Messenger functions, including the transport of hormones and the signalling of tissue damage
6. Regulating body pH
7. Regulating core body temperature
8. Hydraulic functions, including the regulation of the colloidal osmotic pressure of blood

Six Basic Nutrients Required for Good Health .

Carbohydrates : Sources of carbohydrates include grain products such as breads, cereals, pasta, and rice as well as fruits and vegetables

Protein: Main sources of protein are animal products like meat, fish, poultry, milk, cheese and eggs and vegetable(beans, lentils, dried peas, nuts) and seeds.  

Fat: The fat in food includes a mixture of saturated and unsaturated fat. ...meats and milk products and vegetable oils.

Vitamins: Carrot, milk,fish,and fruits and vegetables.

Minerals:calcium and magnesium are important for bone structure, and iron is

Water.
