Poly A is added to the end of a eukaryotic mRNA modified. Polyadenylation is the combination of a poly(A) tail to a messenger RNA. It also consists of multiple adenosine monophosphate. In other words, it is a stretch of RNA that has only adenine bases. In eukaryotes, polyadenylation is one of the process which produces mature messenger RNA (mRNA) for translation.
Auroras occur in the <u>"thermosphere".</u>
The thermosphere lies between the exosphere and the mesosphere.It is a district of expanding temperature in Earth's climate that is situated over the mesosphere.
The thermosphere significantly helps in ensuring the earth and making space investigation and present day types of correspondence conceivable. It additionally supports and ensures life on the planet. It reuses water, retains the sun's energy, and makes a moderate temperature.
The aurora (Northern Lights and Southern Lights) generally present in the thermosphere. It is a natural electrical marvel described by the presence of streamers of rosy or greenish light in the sky, particularly close to the northern or southern attractive shaft. The impact is caused by the communication of charged particles from the sun with iotas in the upper atmosphere.
Answer:
2^n where n is the haploid number of chromosome (3)
Explanation:
According to the question, this organism has total chromosomes of 6, which means its gametes after meiosis will have a chromosome number of 3. However, a phenomenon called CROSSING-OVER occurs in meiosis I that increases the chance of genetic diversity/variation among species. This process of crossing-over causes chromosomes to be rearranged in a way different from the parents.
However, the possible number of different combinations of chromosomes in the resulting gametes after meiosis can be found using the simple formula 2^n where n is the haploid number of chromosome. In this case, the haploid number is 3, since the total chromosomes are 6. Hence, 2^3 = 8. It can be said that the particular organism in the question can possibly have 8 different chromosomal combinations in its gamete.
Answer :
based on the use of anatomical and genetic evidence to establish ancestral relationships
Explanation :
We know that,
The cladistic approach to primate :
The cladistic approach to primate is defined as phenotypically and anatomical characteristics, genetic and common characteristics that established ancestral relationships.
It is not purely based on phenotypes only, it required genetic and anatomic behaviour and evidences.
Hence, The correct answer is option (III)
Answer:
Energy
Explanation:
Active transport requires energy to move substances across a plasma membrane, often because the substances are moving from an area of lower concentration to an area of higher concentration or because of their large size. Two types of active transport are the sodium-potassium pump and vesicle transport.
