Answer: c]bronchus (bronchi, pl.)
Explanation:
During transcription, mRNA is synthesized using DNA as a template. This process usually takes place in the cell nucleus and is carried out with the help of an enzyme called RNA polymerase.
mRNA plays the role of a messenger hence the term messenger RNA or mRNA in short. Information for synthesis of a specific protein is transcribed on mRNA in the nucleus of the cell. The mRNA then leaves the nucleus and enters the cytoplasm and attaches onto a ribosome. Ribosomes are cell structures fondly called the "work bench " of the cell.
It is in the ribosomes that the information brought by mRNA is translated or decoded and used to synthesize the specific protein that was coded for.
Answer: why it is hard to use dichotomous key in the lab are;
If the organisms you want to use it for are similar.
If you can't see the little characteristics posses by the organisms you are using it for.
If all the pictures does not reveal all the important features of the organisms.
It is very difficult to use it to determine the anatomical structure.
Explanation:
Dichotomous key is an important method that is use in biology to identify organisms by separating or dividing the organisms into two groups. It is a tool created by scientists to help them identify organisms or objects. Once the organisms are group into two, more information is revealed more individually.
The contractile vacuole expels water out of the cell by contrasting.
The correct answer is vestigial.
A vestigial composition is an anatomical characteristic, which no longer appears to exhibit an objective in the present form of an organism of the given species. Usually, these vestigial compositions were organs, which had done some essential activity in the organism at one time in the past.
The examples of human vestigiality are plentiful, involving the anatomical compositions like wisdom teeth, human tailbone, and inside corner of the eye.
