Karst is a type of landscape that is characterized by caverns, caves, sinkholes, and underground streams. These features were all caused by erosion of the underlying rock.
Limestone type of rock usually underlies a karst landscape.
Which of the following definitions describes a physical hazard?
A) The most commonly thought of hazard in construction. This hazard includes radiation, extreme temperatures, noise, and vibration.
B) These hazards can lead to injuries to the joints or muscles by way of heavy, frequent lifting, repetitive tasks.
C) Can be present in dust, fumes, liquids, solids, mists, vapors, or gases of products used at a site or released during a construction job
D) Microorganisms, such as bacteria, fungus, mold, or viruses that can cause illness.

Answer & ExplanationAnswer: A) The most commonly thought of hazard in construction. This hazard includes radiation, extreme temperatures, noise, and vibration.
Explanation:
A physical hazard is defined as "A factor within the environment that can harm the body without necessarily touching it."
Vibration and noise are examples of physical hazards.
Physical hazards include but aren't limited to electricity, radiation, pressure, noise, heights and vibration amongst many others.
Hemopoiesis begins in the red bone marrow, with hemopoietic stem cells that differentiate into myeloid and lymphoid lineages.
Myeloid stem cells give rise to all the other formed elements, including the erythrocytes; megakaryocytes that produce platelets; and a myeloblast lineage that gives rise to monocytes and three forms of granular leukocytes: neutrophils, eosinophils, and basophils.
The given compound is NaHCO3 Sodium bicarbonate which is commonly known as Baking soda.
Oxidation numbers are the charges on ions. When a neutral atom loses electrons it becomes positively charged. When a neutral atom gains electrons it becomes negatively charged.
Here the C represents the oxidation state of carbon in this compound. Compounds are electrically neutral, which is why we set the sum of the oxidation states equal to zero.
Sodium has a +1 oxidation state. Hydrogen has a +1 oxidation state. Oxygen has a -2 oxidation state. There are three oxygen atoms, which means the total oxidation state provided by both oxygen ions is -6. Adding up these oxidation states we get:
1 + 1 + (-6) + C = 0
-4 + C = 0
=> C = 4
This means the oxidation state of carbon in this compound is +4.
Demat means Dematerialisation of share, in simple it is an account with which a person can trade in security market without which a person cannot buy or sell any share in security market.
An ELISA test may be used to diagnose: HIV, which causes AIDS.
