Answer:
I guess it is a Secondary Succession.
Explanation:
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation.
Answer:
Wilson has created the theory of the biogeographic nature of the island, which predicts that the number of species on the island depends on the balance between colonization, the evolution of the novel island species, and extinction.
Explanation:
A new DNA sequence containing 596 species of terrestrial birds from 41 island chains (archipelagos) around the world has been assembled by the researchers. The data combined sample data from their own field visits, research, and field samples from GeneBank colleagues. This information was utilized to build and employ a dynamic model that predicted international relationships that regulate biodiversity variation in their novel analysis approaches. In that, they confirmed two main components of MacArthur and Wilson's initial biogeography theory on the island.
The understanding of biodiversity on the island is important to conservation but also has implications beyond that – when imposing barriers to species dispersal it could enable us to assess better the effects of human activities, and it can contribute to a wider understanding of biodiversity around the globe.
Explanation:
mRNA (messenger RNA): Produced during transcription. Carries the genetic instructions of a gene from the nucleus to the ribosome in the cytoplasm.
rRNA (ribosomal RNA): Together with proteins, composes the ribosome, the organelles that are the site of protein synthesis.
tRNA (transfer RNA): Brings the correct amino acid to the ribosome during translation.
Answer:
The answer is B.
Explanation: Subjective evidence is based on personal suggestions, so that is wrong. Hypothetical is a guess, so it is wrong. So it would be B, since empirical means evidence based on facts and observation.
Hope this helps!
Answer:
C. homozygous recessive
Explanation:
Freckles are a dominant characteristic, that is, they are expressed by people who have dominant and heterozygous homozygous alleles.
In the case of the child shown in the question above, the mother has freckles and is heterozygous, which means that she has recessive and dominant alleles (Aa) for this characteristic, while the father does not have freckles which means that he only has homozygous alleles. and recessive (aa) for this characteristic. If the child was born without freckles it means that she received a recessive allele from the mother and a recessive allele from the father (a + a), in this case, the child is homozygous recessive (aa).
