Answer:
B. Plastics to make hard hats were not available in the 1930s, so workers either did not wear hats or wore hats made from cloth or felt.

omo I don't know but what I tell you it is real and if it does happen but it's not must that somewhere else sees what you can yeah
Answer:
Explanation:
Solids are divided into two main categories, crystalline solids and amorphous solids, based on how the particles are arranged.
Crystalline solids, or crystals, are regarded as "true solids." Minerals are crystalline solids. Common table salt is one example of this kind of solid. In crystalline solids, the atoms, ions or molecules are arranged in an ordered and symmetrical pattern that is repeated over the entire crystal.
Crystalline solids also exhibit anisotropy. This means that properties such as refractive index (how much light bends when passing through the substance), conductivity (how well it conducts electricity) and tensile strength (the force required to break it apart) will vary depending on the direction from which a force is applied. Crystalline solids also exhibit cleavage; when broken apart, the pieces will have planed surfaces, or straight edges.
There are four types of crystalline solids: ionic solids, molecular solids, network covalent solids and metallic solids.
In amorphous solids (literally "solids without form"), the particles do not have a repeating lattice pattern. They are also called "pseudo solids." Examples of amorphous solids include glass, rubber, gels and most plastics. An amorphous solid does not have a definite melting point; instead, it melts gradually over a range of temperatures, because the bonds do not break all at once. This means an amorphous solid will melt into a soft, malleable state (think candle wax or molten glass) before turning completely into a liquid.
Amorphous solids have no characteristic symmetry, so they do not have regular planes of cleavage when cut; the edges may be curved. They are called isotropic because properties such as refractive index, conductivity and tensile strength are equal regardless of the direction in which a force is applied.
Answer: c. small bodies and long limbs in warm-blooded organisms, light colored fur or feathers to reflect sunlight, lack of sweat glands in many organisms, hibernation during hot months
Explanation:
Any adaptation of organisms in the Sahara desert will be ones that enable the organism to survive the heat as best as possible. Any adaptation that traps or absorbs heat will most likely not be seen here.
Organisms are likely to have small bodies to reduce the area that can be affected by the sun as well as fur and feathers that reflect sunlight to reduce the impact of the extreme Sahara sun on their bodies.
A lack of sweat glands are common with desert animals to avoid extreme water loss and it will be common to see organisms hibernating in periods that are especially hot so as not to be adversely affected by the heat.
