Explanation:
Penicillin is a bacteria so it means it causes the production of antibodies which then boost the immune system.
It is like vaccination; small doses of the inactive form of the infection is injected into the body in order for the body to create antibodies resistant to such infection(thereby boosting the immune system).
Hope it helps.
Answer:. have chloroplasts and a cell wall
Explanation:All living organisms are made up of cells.some organism are made up of one cell (Unicellular) and other organism are made up of many cells(multicellular).
Cells are made up of organelles and the organelles present in a cell differ in animals cells and plant cells.
A feature that animals cells have which plant cell do not have is the presence of centrioles.
Features that plant cell have which animals cells do not have are the presence of chloroplast ,vacuole and cell walls.
Animals do not produce their food but plants do.Green Plants produce their food through chloroplast,which contains chlorophyll.
Plants has cells walls which is rigid and made up of cellulose,lignin and pectin.this rigid structure of the cell wall contributes to the rigidity of plants stems and roots.
Option A is incorrect because plant and animal cells have mitochondria.
Option B is incorrect because plants cells have both plasma membrane and cell walls.the cell wall surrounds the plasma membrane.
Option C is incorrect because plants contains Golgi apparatus and vacuole
Answer:
Polymerase chain reaction (PCR) test is used to duplicate traces of DNA from any living form, for identification purposes. The correct sequence is 1, 3, 2; based on the options given.
Explanation:
The steps to be followed for the PCR procedure are:
<em>Denaturation</em>
Option 1. Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links
<em>Annealing</em>
Option 3. Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.
<em>Elongation</em>
Option 2. Incubate at 72°C to promote the extension of the DNA strands, actually extending them.
