Answer:
Plaster cast is made up from dry muslin containing starch or dextrose and calcium sulfate.
Explanation:
It is applied to protect and is immobilize an injured bone or joint because it provides rigidity.
It is also used to help the bone and joint from reduce pain that is created during movement.
When plaster becomes wet,it reacts (Between water and calcium sulfate) and produces heat that eventually sets the plaster.It becomes hard when it dries.
The color of plaster casts are smooth and white.
Answer: Option A ,Band C.
Explanation:
Sympatric speciation is the evolution or isolation of new species from the original populations of species occupying in the same geographical area. Sympatric speciation commonly occur due to sexual selection of mates can cause reproductive barriers or isolation which keep gene pools separate. A plant with extra set of homologous chromosomes is an example of sympatric speciation.
Answer: Gender identity
Explanation:
Gender identity is how a person sees themselves their own internal sense and personal experience of gender. Only the individual can determine their own gender identity. Gender indentity refers to the degree to which we see ourselves as feminine, masculine, transsexual or perhaps even nongender and having no gender at all.

Renewable resources are those which can be replaced naturally and repeatedly. For example, water, oxygen, and plants are examples of renewable resources.
Wood is a renewable resource as it is a part of trees. Trees are able to be replanted and can be cut down again, once they reach maturity. Plastics, glass, and steel are known as non-renewable resources as they cannot be replaced at a sufficient rate and usually have a limited supply. For example, plastics are created using a variety of different substances such as natural gas and oil (polyethylene). The Earth contains a limited supply of both substances, so plastic is deemed as being non-renewable.
As a result, the only renewable product in the choices provided above is a wooden spoon.
The surface area will be:
S.A. = 6l²
S.A = 6(100 x 10⁻⁶)²
Volume = l³
Volume = (100 x 10⁻⁶)³
Surface area to volume ratio:
[6(100 x 10⁻⁶)²] / (100 x 10⁻⁶)³
S.A : Vol = 6 x 10⁴
