Biology
1 answer:
Yanka [14]2 years ago
4 0

Answer:

A frameshift mutation.

Explanation:

A frameshift mutation is when one adds an extra nucleotide to a series of nucleotides. This will mess up the order of the nucleotide, thus when it forms the codons, and eventually, the amino acids; all of the codons are wrong, thus all of the amino acids are wrong.

In this situation, an extra nucleotide is added to a sequence of DNA, this results in all of the other nucleotides getting pushed over by (1). Thus, all of the nucleotides form the wrong codons and the wrong amino acids. Therefore, a frameshift mutation has occured.

Is it true that ocean biomes contain a wider biodiversity than land biomes why or why not?
EastWind [94]
The difficulty with this answer, lies in the fact that not all of land and ocean biomes have been completely explored. The ocean is vast, covering approximately 70% of the Earth's surface, with literally vertical miles or kilometers of depth, and with some areas with sparse to no biodiversity. The same can be said about certain areas of large deserts with very low levels of biodversity, void of life, like vast deserts of the Sahara or Gobi. But, the Amazon rain forest contains still unknown species of plant and animal life, just like the ocean. Because of its vastness, intellectually, I would say  the ocean contains more biodiversity, but the answer is scientifically, as of now, yet to be proven one way or the other.

What did Darwin conclude about the finches on the Galapagos Islands that later supported his theory of evolution? Check all that
Ahat [919]

Answer:

The finches on Galapagos Islands had different beak

The beaks of the finches changed over time

The Galapagos finches had a common ancestor

Explanation: Darwin's Finches are a good example of natural selection and adaptive radiation of evolution. The different finches in Galapagos Island have emerged from a common  black, seed eating, short beak finches. This is called adaptive radiation, where different species arose from a single ancestor.

Due to changes in the natural environment, food resources, some finches have a long beak. This long beaks help them to eat insects. As a result, the competition will be less and nature selects them to survive in the new environment. This is a natural selection of evolution.
