Answer:
Option-3
Explanation:
Hybridisation is an artificial process which is performed by humans to form a product by the combination of genes.
The genes or trait of desire are selected from two different organisms as a result of which a new hybrid organism is formed which contains the selected traits of organisms. The hybridisation can also be termed as the selective breeding and was practised by the humans from 10,000 years ago.
Since the hybridisation produces the infertile offspring as it produced artificially therefore Option-3 is correct.
Answer:
By phylogenetic analyses
Explanation:
The target of rapamycin (TOR) is a major regulator of growth only found in eukaryotic organisms. The TOR pathway is known to regulate critical cellular processes including, among others, cell growth. The TOR protein is a kinase capable of activating translation by phosphorylation of the ribosomal S6 kinase (S6K) and the eukaryotic translation initiation factor 4E binding protein (4E-BP). In this regard, phylogenetic studies have shown that this pathway involves duplication events of ancestral kinases, as well as sub-functionalization of the S6K kinase.
B. A question
You need to think of a question to begin to make an experiment, otherwise how do you know what you’re trying to find?
