Answer:
A trio of antibiotics that had become powerless against MRSA decades ago proved effective in infected mice when used together.
Although more testing is needed, the results suggest that combinations of already-approved antibiotics might add to our options to combat MRSA infections.
Explanation:
chloroplasts is an organelle that actually carry out the photosynthetic activity will be unable to function if placed in a dark environment.
Answer:
Single stranded template to produce a double stranded product.
Explanation:
Polymerase chain reaction (PCR) is a technique in the laboratory that is used to make many copies (millions or billions) of a particular region of deoxyribonucleic acid (DNA).
The reaction utilizes primers which are short pieces of single stranded oligonucleotide templates to yield a double stranded DNA.
Two primers are used in each PCR reaction, and they are designed to identify the target region to amplified they bind to opposite strands of the template DNA at the edges of the region to be copied. The template DNA is copied and a complementary DNA is produced. The end product of the reactions a double stranded DNA that is produced from the template dna. The new DNA is the exact copy of the template dna.
Answer:
The correct answer is (1) digestive and circulatory
Explanation:
Digestive system helps in digestion of complex organic matter present in the food like polysaccharides, proteins, lipids, etc. So due to the function of the digestive system, these complex molecules are converted into simpler forms like glucose, amino acids, etc. Then these simpler forms are absorbed in the body through intestine.
Ribosomes help in the production of proteins which requires amino- acids so the absorbed amino acids are moved into the cells through the circulatory system. Therefore digestive system and circulatory system provide the molecules required for metabolic activities.
The answer is A. Stressor
