Answer:
all cells come from other cells
Answer:
This methodology enables to measure simultaneously both the result and exposure in the group under study
Explanation:
A cross-sectional method is a type of scientific design based on observational data. The cross-sectional studies involve the use of diverse groups that differ in the variable investigated but share other features (for example, individuals with the same educational background, ethnicity, economic status, etc). This class of studies is generally used in developmental psychology.
The correct answer is the option (A) heparin.
DVT refers to a condition called the deep vein thrombosis when a blood clot occurs in the deep veins of the legs in the body. PE refers to the Pulmonary embolism when a blood clot is observed in the artery of the lungs.
The drugs used in the treatment of DVT and PE are called the anticogulants which interfere with the process of blood clot formation. Heparin and warfarin are the two older anticoagulants used in the prevention and treatment and prevention of DVT and PE. Heparin is given intravenously to treat DVT and PE whereas, warfarin is taken as a tablet or pill through the mouth. Heparin allows the body's clot lysis mechanism to break down the existing clots and it is also a natural anticoagulant produced by the basophils and the mast cells of the blood.
Thus, heparin is the old drug that is used subcutaneously to prevent DVT in high-risk patients and intravenously to treat DVT and PE.
Answer:
Aspergillosis and Mucormycosis are caused by two different fungi groups.
Explanation:
Aspergillus causes Aspergillosis. Aspergillus is a kind of mold or fungus which is found in both inside and outside environment and it may not always cause the disease if inhaled.
Mucormycosis is caused by Mucormycetes. Mucormycetes are group of fungi that are specifically found in soil and other decaying organic matter like leave, animal dung etc. They are more common in soil as compared to air. People with weak immunity system usually are affected by this fungi else these fungi's are not very harmful. They cause an infection in lungs/sinuses when inhaled
resolvingpower on the microscope?
Answer:
Explanation:
The resolving power of the microscope is dependent upon the objective lens. It can be measured by the ability of the lens to differentiate between the two lines or points on the specimen under observation. The more the resolving power the smaller will be the distance between the two lines or points that can be distinguished.
The following are the two ways that can be used to enhance the resolving power on the microscope:
Using a lens that has a higher aperture.
Decreasing the amount of light being entered into the microscope that means using light of less wavelength.
