Homeostasis<span> can be defined as a property of an organism or system </span>
The answer is D. In a
geological era, when the plants and animals
in the then environment die, they get buried
in sediments. These sediments are covered
by other sediments of another geological
time within which are the remains of dead species
of the then geological era. These sediments from different geological times have different properties hence
form visible strata that can be studied to identify the kind of environment in the then geological time. Their
fossils can also be studied to identify
the kind of species that roamed the earth during the time.
Answer:
I think the answer is D ... but I am having a second thought I think it is B
Answer:
RNA splicing is the intron removal and exon binding in the mRNA before leaving the nucleus.
Explanation:
Alternative splicing of identical RNA transcripts into different cell types can produce different mature mRNA molecules that translate into different polypeptides.
The genetic information encoded in the AND is transcribed to a copy of RNA (primary transcript). This copy is then modified with the addition of the 5 ’cap (CAP) and the poly-A tail, the excision of the introns and the union of the exons (splicing). The mature mRNA then goes to the cytoplasm, where it is translated into proteins.
