Answer:
The correct answer is "C-to-T transition".
Explanation:
When cytosine is hydrolysed or methylated it could result in the formation of an uracil via the deamination of cytosine. The uracil that is formed in the genomic DNA could be repaired by DNA repair pathways, but it could result in the formation of a tyrosine. These series of mutations are known as "C-to-T transition" because it starts with a cytosine and ends with a tyrosine. This kind of somatic mutations are very studied because they had been found in human breast tumors.
Trophic levels can be represented by numbers, starting at level 1
with plants. Further trophic levels are numbered subsequently according
to how far the organism is along the food chain.
Level 1: Plants and algae make their own food and are called primary producers.Level 2: Herbivores eat plants and are called primary consumers.Level 3: Carnivores that eat herbivores are called secondary consumers.Level 4: Carnivores that eat other carnivores are called tertiary consumers.Level 5: Apex predators that have no predators are at the top of the food chain.*Hope that helps XD*
Answer:
hydrogen gas dominated earth's first atmosphere?
The C option is Correct.
- All the Galapagos finches exist on the same island.
Galapagos finches is a piece of evidence supporting the theory of evolution.
Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
