Answer:
The correct answer is - option A. They evolved separately as they moved north and became two separate species
Explanation:
Greenish warbler is a leaf warbler present in many regions in the world and shows migration in winters in the Indian region. The main region of the migration is Tibetan Plateau.
They migrated from the southern part of these birds range and moved north and evolved separately from the main species and become two distinct species due to their geolocation and environment change.
Answer:
True
Explanation:
Exon is a part of gene that encodes for final mature RNA after processing. In the process of RNA splicing, introns are removed and exons are retained and joined to produce mature mRNA.
They have protein coding sequence and also UTR ( Untranslated Region ) which plays a role in translation termination and post transcriptional gene expression. Human genome has only 1.1% exon and is majorly composed of introns and intergenic DNA.

Answer:
Eukaryotic cell membranes:
phosphatidylserine - it is found in the inner leaflet of the membrane and plays role in the cell cycle signaling.
phosphatidylcholine - these are a major group of the membrane in eukaryotes.
phosphatidylinositol - it is also present in eukaryotic cells only in significant amounts
both bacterial and eukaryotic cell membrane:
phosphatidylglycerol - directly activates lipid-gated ion channels in both type of cell membrane
phosphatidylethanolamine - helps in assembling membrane proteins.
cardiolipin - it present in both eukaryotic and bacterial membrane however it makes 20% of the inner membrane of the mitochondrial membrane
Bacterial membrane:
No particular lipid
Centaurea maculosa which just means pioneer species in short
Answer:
C - Rosalind Franklin is the correct answer
