Hello!
The type of polymer that is made by bonding an alkene to one or more alkanes or alkenes is called addition polymer
Addition polymers are those whose polymerization reaction doesn't produce low molecular mass compounds but the bonding of molecules one after the other. Such a reaction implies that there is a rupture in the bonding between monomers (the building blocks of the polymer) to allow the formation of a chain.
Bonding an alkene to one or more alkanes or alkenes is an example of an addition polymerization.
Have a nice day!

Answer:
The correct answer is option c. "Tetracycline must be discontinued before beginning the isotretinoin".
Explanation:
Isotretinoin is a medication used to treat cases of severe acne, having dramatic positive effects since the patients start the treatment. However, the use isotretinoin should be monitored by a doctor because it is hard to process and could cause renal side effects. In this case, the patient must discontinue its treatment with tetracycline before start using isotretinoin.
DNA and RNA have completely different purposes in us. DNA stores and transfers genetic information (Eye and hair colour, skin colour, etc..). RNA codes amino acids and makes proteins. DNA is double stranded while RNA is single stranded. DNA uses adenine, thymine, cytosine, and guanine; while RNA uses adenine, cytosine, uracil, and guanine.
Answer:
The correct answer is: False.
Explanation:
- A Fishery collapse can be defined as the condition in which the composition of different species of fishes forming a food chain or a food web and located in a marine or aquatic community undergoes a drastic alteration.
- The alternation can be caused due to environmental or anthropological factors.
- A fishery collapse usually affects the larger fish population like sharks and tuna as their commercial and economic demand is higher.
- Excessive fishing cause the population of the large fishes to decline without affecting the small fish population.
- This is because the small fishes do not have high economic or commercial demand, hence they have very less probability of being angled or captured.
