Answer:
Indeed, both monogamy and polygamy are reproductive strategies adopted by the different species of the animal world.
Explanation:
Polygamy implies the adoption of a unique and stable partner by an individual, with which in principle it will reproduce. Different species, including humans or penguins, in addition to maintaining the same pair for reproductive purposes, generate bonds of coexistence.
Other species (in fact, most animal species) are not guided by this type of relationship, but fulfill their reproductive functions in a random way, that is, with several individuals of the same species in a random way, which is called polygamy. In this case, there is a constant change in the reproductive couple, which responds to multiple factors such as for example a gender disproportion within the species (for example, many females and few males would make those few males have to comply reproductive functions with several females during the mating period), or due to the non-sedentary nature of life of these species.
Answer:
D. none of these choices are correct
Explanation:
substituting -2 as x into the expression,
-2x + 4x
-2(-2) + 4(-2)
4 + (-8)
4 - 8
-4
the answer should be -4
In eukaryotes, the sequences of a primary transcript included in the mrna are called exons. whereas sequences spliced out of the mrna are called introns.
<h3>The main transcript is mRNA, right?</h3>
Pre-mRNA is the name of the first byproduct of a protein coding gene's transcription (or primary transcript). It is known as mature mRNA or processed mRNA once it has undergone processing and is prepared to be exported from the nucleus.
<h3>What constitutes the eukaryotic main transcript?</h3>
processing of mRNA in eukaryotes. The process by which the data in genes (DNA) is used to create RNA is known as transcription. Before becoming functional, the freshly created RNA, often referred to as the principal transcript (a transcript is the end result of transcription), or pre-mRNA, undergoes additional processing.
