Answer:
bolus,chyme and feces
Explanation:
The enzyme in the saliva digests starch to maltose. The tongue rolls the food into small round masses called boluses, then pushes the bolus into the pharynx for swallowing.
The stomach wall is made up of thick circular and longitudinal muscle layers. These muscles contract and relax producing movement that aids in the mixing of the contents of the stomach. This mixing is known as churning and results in the formation of a fluid called chyme.
The remaining semi-solid waste material is then passed to the rectum where it is stored temporarily and eventually eliminated from the body as feces through the anus as the sphincter muscles relax.
When you start the PCR amplification reaction, you have a template which has sequences where the primers will anneal. The forward primer anneals in the sense strand and the reverse one in the complementary sequence (see attached figure).
After the first PCR cycle, two types of fragments are obtained. First those which come from tha 5'-3' sequence, that are 3'-5' and will anneal the reverse primer in the following cycle. This fragments have the correct 3' end, but the 5' includes part of the template that doesn't correspond to our target (see attached figure)
Second, those fragments that come from the 3'-5' sequence, that are 5'-3' and will anneal the forward primer. This fragments also have the correct 3' end, but the 5' includes part of the template that doesn't correspond to our target (see attached figure).
Now, during the second cycle, are produced the first fragments that have the precise length of the sequence that we want to amplify (see attached figure).
So, it's not until the third cycle that the reaction starts amplifying exactly the sequence of desired length.
Our ears use vibrations to detect sound.
Inside our ears we have an eardrum, this eardrum is connected to three small bones known as Ossicles. When something makes a sound is creates a vibration that makes the eardrum vibrate and pass this vibration through the Ossicles to the Co<span>chlea which allows us the comprehend the sound something is making.
I hope this helped. Have a great day!</span>
Solution:
The dna replication enzyme that most closely resembles rna polymerase is Primase. Which is the RNA that synthesizes RNA primers during DNA replication.
Thus this the required answer.
One of the many places that the students would be able to grow grass is a nutrient rich soil area.
