<span>The endosymbiotic theory explains that mitochondria and chloroplasts descended from the same type of bacteria. Symbiosis is an interaction between two organisms of different species, and endosymbiosis is a type of symbiosis in which one organism lives <span>inside </span>the other one. According to the endosymbiotic theory, a host cell ingested symbiotic bacteria, which specialized into mitochondria or chloroplasts. The evidence for this theory is that mitochondria and chloroplasts, like bacteria, have their own circular DNA. They also have their own transcriptional and translational machinery.</span>

Why does this recent discovery about the galapagos finches prove that it’s often challenging for scientists to determine when tw

34kurt

Because the species of finches on the Galápagos island have various appearances but still mate with other finches and produce fertile offspring making it is difficult for scientists to distinguish between two groups of individuals as separate species.

<h3>What is the island of Galápagos?</h3>

The Pacific Ocean island of Galápagos is located to the west of Ecuador. It is a volcanic island known for its diverse and endemic types of living things.

<h3>Why is it difficult to find new species in Finches?</h3>

Charles Darwin spent several years studying the many species of finches on the Galápagos island. He saw a great deal of variation in these finches, which supports the hypothesis of natural selection.

However. it is challenging for scientists to discern between two separate species because the species of finches on the Galápagos island have a variety of features that are different but still mate with other finches and produce fertile offspring.

What is the sequence of cases on dna strand b from left to right? (See picture)

Bas_tet [7]

Answer:Dna template- 5' ACTCCTGAA 3'

3' TGAGGACTT 5' complementary base

Explanation: Dna consist of a double stranded helix structure. Replication occurs to make extra copies of DNA strand. The DNA strand use to make extra copy is the template strand while the mirror image is the complementary base.

Replication occurs in 5' to 3' direction.

For complementary base in DNA Adenine complement thyamine

Cytosine complement Guanine

i.e A-T

C-G

Hence the complementary base in 3'-5' direction is 3' TGAGGACTT 5'

Vinil7 [7]

Disruptive selection or diversifying selection describes the changes in population genetics where extreme values for a trait are favored over intermediate values.

So according to this definition, the conclusion can be derived as :

The most common circumference(s) to be after 10 generations of diversifying selection will be greater than 2 cm and less than 2 cm.
