Answer:
Explanation:
The bacteriostatic antibiotics can be defined as those antibiotics, which prevents the growth of bacteria. These keeps the growth of bacteria in the stationary phase so that bacteria cannot cause harm to the host.
The bactericidal antibiotics can be defined as those antibiotics, which kills the bacteria.
The example of bacteriostatic antibiotic is Tetracycline that it inhibit the bacteria ribosome production of proteins. This way bacterial growth and reproduction will get restricted.
The example of bacteriocidal antibiotic is polymyxin B. It causes injuries to the plasma membrane of the bacteria which can be lethal for bacteria.
Answer:
Explanation:
Control Unit retrieves data and instruction in the same manner from one memory. Design and development of the Control Unit is simplified, cheaper and faster. Data from input / output devices and from memory are retrieved in the same manner.
There are choices for this question namely:

Leukopenia
Weight gain
Polycythemia
Hepatomegaly
Jugular vein distension
The correct answers are "weight gain", "hepatomegaly" and "jugular vein distension". Along with bipedal edema, these signs are associated with the complication of COPD which is called <em>cor pulmonale</em>. Cor pulmonale is a kind of right sided heart failure wherein blood pools to the systemic circulation because the right side of the heart cannot overcome the pulmonary vascular resistance brought about the COPD. Pooling of blood in the systemic circulation causes bipedal edema, hepatomegaly (cardiac cirrhosis; congestion of the liver), weight gain (increased interstitial fluid volume), and jugular vein distension. </span>
Answer: a. Adenine
Explanation:
Two types of chemically similar nucleic acids, DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are the principal information-carrying molecules of the cell. The bases adenine, guanine, and cytosine are detected in both DNA and RNA while thymine is observed only in DNA, and uracil is located only in RNA. When it comes to defining the nucleic acid-based in the nature of its nitrogen- and carbon-containing ring structure we have the variation that answers the question. While b. Uracil, c. Cytosine, and d. Thymine only contains a single ring, which we call pyrimidines, the biomolecule a. Adenine contains a pair of fused rings that we call purines, the right answer for the question.
