<h2>A) option is correct </h2>
Explanation:
- RNA is a linear polymer of ribonucleotides
- Sugar in RNA is ribose instead of deoxyribose which is present in DNA
- The four nitrogenous bases present in RNA are adenine, cytosine, guanine and uracil whereas that in DNA are adenine, cytosine, guanine and thymine
- RNA molecules carry genetic information from DNA to proteins, cannot transmit from one generation to next generation as a genetic material
- Due to steric hindrance by the 2'-OH group of ribose sugar, RNA unable to form double helix
The ansseer is Iridium.
The atomic number of iridium is 77 and it comes just before platinum (atomic number = 78).
In iridium,
The number of electrons = no. Of protons = 77.
The no. Of electrons and the no. Of protons is same as atomic number.
Answer:
Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.
hope this helps:)
Answer:
The species is not prey to what is already living there and as a result may reproduce uncontrollably and end up causing the other species to go extinct by stealing the resources they need.
