<h2>Resistance to antibiotics </h2>
Explanation:
Bacteria are single-celled organisms usually found all over the inside and outside of our bodies
- Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic
- Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections,the bacteria survive and continue to multiply causing more harm
- There are two main ways that bacterial cells can acquire antibiotic resistance,one is through mutations that occur in the DNA of the cell during replication and the other way that bacteria acquire resistance is through horizontal gene transfer
- Through the process of replication bacteria develop mutations that make them resistant to antibiotics
- Bacteria with the resistant mutation have a better chance of survival against antibiotics
- Resistant bacteria continue to multiply even when exposed to antibiotics
- In horizontal gene transfer,antibiotic resistant genetic material is transferred between different bacterial cells which can happen in three different ways: transformation,transduction or conjugation
DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. ... DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine.
I don't know witch definition you mean, but here: https://www.google.com/search?q=google+dictionary&rlz=1C1CHBF_enUS871US871&oq=google+dic&aqs=chrome.0.0j69i57j0l6.3972j0j7&sourceid=chrome&ie=UTF-8#dobs=blowout
Answer: B
Explanation:
During polymerization of nucleotides to form nucleic acids, the hydroxyl group on the phosphate group attaches to the 3’ carbon of a sugar of one nucleotide to form an ester bond to the phosphate of another nucleotide. The reaction forms a phosphodiester linkage and eliminates a water molecule.
The DNA strands generally runs from 5 prime to 3 prime direction.
The right answer is b. Tree.
Some plants (like trees) have evolved with different unusual nutritional adaptations over time. Heterotrophic plants are plants that use only or partly a source of organic carbon to grow, unlike the most common autotrophic plants, which use inorganic carbon and water to grow, often through the process of photosynthesis (photoautotrophic).
