Monomers are molecules whose linkage between them form polymers.
<h3>What are monomers?</h3>
Monomers are molecules that have a low molecular mass.
<h3>Characteristics of monomers</h3>
- When many monomers come together through chemical bonds they form a polymer, which is a macromolecule.
- Natural monomers allow the formation of biomolecules found in living beings.
- Carbohydrates, for example, are macromolecules that are created from the bond established by monosaccharides (monomers).
Therefore, we can conclude that polymers, in short, are chains of monomers -generally joined by covalent bonds-.

Identical twins are formed through the process of meiosis where a fertilised egg separates to form two identical cells with a common genetic information.
Fraternal twins on the other hand are developed from the fertilisation of two different eggs and two sperm cells. This type of twins possess unique genetic information.
Answer:
A) Sedimentary
B) Weathering
Explanation:
A sedimentary soil/rock is formed when carrying agents such as wind or water carries rock pieces or soils particles from faraway places and deposit them at one place through a process known as lithification. However, increased pressure and temperature causes weathering of rocks. Changing temperature causes a rock to expand or cool alternatively thereby giving rise of internal stresses. While exfoliation is caused on increasing pressure.
Answer:
Brain ----- glucose and amino acids.
Heart ------- fatty acids and triglycerides.
Explanation:
The sources of energy utilized by the brain is glucose under well-fed whereas the sources of energy utilized by the heart under well-fed condition is fatty acids. During starvation, the source of energy used by the brain is amino acids from skeletal proteins when glucose is not available while on the other hand, during starvation, the heart utilized triglycerides as a source of energy in the absence of fatty acids.
