National Aeronautics and Space Administration (NASA) has developed a series of interactive maps and graphs to describe the global climate and how it has changed over time. They focus on 5 key climate indicators:
carbon dioxide concentration
global surface temperature
Arctic sea ice
land ice
sea level

Correct Option: C

Hermaphroditism is a form of sexual reproduction. Hermaphrodite is an organism that has reproductive organs normally associated with both male and female sexes. Hermaphroditic plants—most flowering plants, or angiosperms—are bisexual. Hermaphroditic animals—mostly invertebrates such as worms, moss animals, trematodes, snails, slugs, etc—are usually parasitic, permanently attached to another animal or plant.

Correct Option: B

A type of helicase enzyme called DNA helicase catalyzes the unwinding of the DNA helix at the time of replication. It uses the energy released through hydrolysis of ATP (Adenosine triphosphate) to break the hydrogen bonds between the two strands. The enzyme is needed to separate the two strands of DNA also during transcription and DNA repair.

Poliomyelitis, often called polio or infantile paralysis, is an infectious disease caused by the poliovirus.Poliovirus is usually spread from person to person through infected fecal matter entering the mouth. It may also be spread by food or water containing human feces and less commonly from infected saliva.
