The correct answer is (b) Secondary succession
Secondary succession is the phenomenon in which redevelopment of species takes place when the native species of a region dies. In 1988, secondary succession was seen in the Yellowstone Park. The year faced drought conditions because of fire. A large area was burned as a result of forest fire. This fire destroyed a large area of botanical life. Life survived and redeveloped, there was growth of some plant species. Some pine saplings were also seen after the growth of grass, more animals migrated into the forest and the biodiversity started again as a result of secondary succession.
D. Mendel's experiments proved that different offspring of the same parents inherit different characteristics.
You need to discuss the different roles of different types of RNA:
mRNA allows the creation of a primary transcript of DNA which can be taken from the nucleus to the ribosome.
rRNA makes up the structure of the ribosome, where translation, the synthesis of a polypeptide chain, occurs.
tRNA transports amino acids to the ribosome and matches the RNA codon with its anticodon, and joins the amino acid to the polypeptide chain that is being created.
The correct answer is "C". 'Proton'. The number of protons is equal to the atomic numbers.
I hope this helps!
