The answer is D. Just think how hard it would be to see a moth of that colour when just about everything during that time period is grey.
Answer: Thermal energy flows from a warmer material to a cooler material. When thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three ways heat is transferred into and through the atmosphere: Radiation, conduction and convection.
Radiation is when energy, in the form of electromagnetic radiation, is emitted by a heated surface in all directions and travels directly to its point of absorption at the speed of light; thermal radiation does not require an intervening medium to carry it. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.
Answer:
Disulfide linkage/bond
Explanation:
The tertiary and quarternary structure of the protein is stabilized by Disulfide linkage which is formed between two thiol groups in the protein. 2-mercaptoethanol is a reducing agent that breaks this disulfide bond.
A protein becomes denature when it loses its native configuration and becomes inactive. So as 2-mercaptoethanol breaks disulfide bond in protein it looses its native configuration and becomes denatured. 2-mercaptoethanol is used in SDS-PAGE to separate protein subunits. Therefore the correct answer is Disulfide linkage/bond.
Answer:
Transboundary
Explanation:
Transboundary refers to a highly contagious disease that has the potential to spread extremely rapid irrespective of national boundary. They cause high mobility and motility in the susceptible animals. An example of such diseases include Avian Influenza and the African Swine flu.
Zoonotic disease is disease that can be transmitted from animals to Humans example anthrax.
Exotic disease refers to a disease that does not normally occur in a particular region
Emerging diseases are those that have recently appeared and are cases are rapidly increasing.
Epizootic are those that appear in a large number of animals in the same place at the same time
Answer:
The reason why toxic chemicals are classified as hazard because they can do as much damage as hazard things and can cause a serious of problems to one's health, for something to be hazard it can be flammable, and toxic chemicals are just that.
