Answer:Ways of protecting one's self from human sources of biological hazards include: Effective use of personal protective equipment such as hand gloves, nose masks, face cover, shoe cover.
Explanation:Human sources of biological hazards may include waste products from human such as faeces, urine and also fluids such as blood from bleeding wound, saliva and so on. These substances may harbor bacterial and viral infections which may result in biological hazards. Therefore, good personal hygiene and use of personal protective equipment will protect one from biological hazards related to human sources.
A is the correct answer to the question
Answer:
A native-species
Explanation:
A native-species is one that normally lives and thrives in a particular ecosystem. They are any species that developed within the surrounding habitat.
They are usually found in an ecosystem because of natural processes like evolution or natural selection. They are known to occur naturally within a given habitat as opposed to species that are introduced.
In order for energy to be able to be created, ATP(adenosine triphosphate) needs to form in either photosynthesis or krebs cycle from ADP + P(from NADPH). When ATP is available, huge amounts of energy are released when needed by slicing one P atom from ATP So that it can again become ADP and undergo lots of processes to become ATP again. So energy is added from tearing of Phosphate Atom due to tearing of phosphoanhydride bonds. This is possible because of process known as hydrolysis, when ATP is in equilibrium with water and some electrons. And the process of ADP becoming ATP is recharging and occurs in mitochondria.
The processes are hydrolysis and rechargeation, but most important process is Krebs Cycle, where all of this happens.
Answer: B. The color of a mineral's powder doesn't change.
C. The densities of many minerals are quite similar.
D. A mineral can break in only one way.
A mineral is a naturally occurring inorganic compound. It is a chemical compound that usually found in crystalline form. The color of the mineral's powder can change because of the oxidation or reduction of particles present in it. The density of many minerals cannot be same because all mineral particles exhibit different composition of atoms or molecules which are responsible for physical and chemical structure of minerals. Hence, minerals vary in density. A mineral can be broken down into many ways like fracture, cleavage and other methods.
