Point mutation:
In point mutation, one nucleotide is swiped for another.
Frame shift mutation:
Frame shift mutation are due to either insertion or deletion of nucleotide. This causes the entire DNA to elongate or shrink in size.
Frame shift mutation may alter all the codons that occur after insertion or deletion.
Answer No 1:
The correct option is c) Both mitochondria and chloroplast contain DNA that is different from the nucleus.
Explanation:
The theory of endosymbiosis proposes that all the eukaryotic organisms have arisen from prokaryotes. This theory proposes that organelles such as DNA and nucleus were once prokaryotic cells. These smaller prokaryotic cells were engulfed by the larger prokaryotes which gave rise to eukaryotes eventually. These organelles possess their own DNA which is different from the DNA of the nucleus.
Answer No 2:
The correct option is C) aerobic organisms
Explanation:
The scientists propose that the initial conditions of the Earth were not favourable for supporting aerobic life. Scientists propose that photosynthetic organisms like cyanobacteria released oxygen into the environment which made the life of aerobic organisms possible on Earth.
Answer No 3:
The correct option is A) It proved the theory of spontaneous generation.
Explanation:
Spontaneous generation can be described as the generation of life from non-living things. Some scientists proposed that living organisms are formed by non-living things.
Zooxanthellae and the hard coral-Zooxanthellae are the symbiotic algae that live within the hard or stony corals. The symbiotic relation is based on the coral's inability to generate sufficient amounts of food and the algae’s ability for photosynthesis and converting chemical elements into energy. - mutualism
The remora and the manta ray-The benefits to the remoras and remora for living in such close association with their larger hosts are clear, but there is a debate about whether the manta rays receive a significant return in benefits from these relationships. - mutualism
The tiger shark and the green sea turtle - the turtle is eaten by the shark-predation
The dolphin and the school of trevallies-To feed, dolphins use a fast, surprise attack, and, unlike the hunting packs of trevallies, dolphins can successfully hunt alone. - predation

14C still must have 6 protons in the nucleus, plus 8 neutrons in the nucleus, and 6 electrons orbiting around the outside.
D) species
To figure this out think of the order in which you classify organisms in. Domain, kingdom, phylum, class, order, family, genus, species (in the order from most diverse to least)
