Answer:
The correct option is d) UAG
Explanation:
Central dogma can be described as the process in which the transcription and translation occurs. The process by which mRNA is made from the DNA is called transcription and the process by which proteins are made by mRNA is called translation.
The first codon present on the DNA is TAG. The mRNA formed from this codon will be AUC. When this mRNA will travel from the nucleus to the cytoplam, the tRNA will bring the anticodons UAG for the first mRNA codon. Hence, the correct option is D.
There are basically three types of evolution divergent, convergent and parallel evolution.
a) Divergent Evolution – As the name depicts the species in this form of evolution becomes divergent i.e they evolve to become different from each other. This form of evolution is responsible for the current diversity of organisms existing on planet earth. For example human and apes evolved from a common primate ancestor.
b) Convergent Evolution – In this evolution, different species of organisms living in a similar biosphere start share common traits in the form of analogous features. For example – Whale and fish are not closely related species but they both have fins which are different in structure but have the same function.
c) Parallel evolution – In this evolution the similar characteristics between the two set of organisms are maintained though the two species continue evolving separately. For example - marsupial mammals of Australia and the Placental mammals
1. plants do not need and complex excretory organ because it creates a very small amount or nitrogenous waste.
Answer:
the number of prey and predators has decreased
Explanation:
this is because of increased rate of hunting .the prey such as elephants and rhinos are being hunted for their horns while predators are also being hunted because of their skin.
also due to man and wild animal conflicts which happen in areas nearing the forests ,both prey and predators are killed.
