A complex chemistry is most related to maintaining a stable internal environment.
Answer:
This question is asking to identify the directional relationship between the following organs. They are explained below.
Explanation:
1. The heart is MEDIAL to the lungs because it is located towards the middle in relation to the right and left lungs.
2. The knee is DISTAL to the hip because it is farther away from the point of attachment of the hip joint.
3. The wrist is PROXIMAL to the hand because the wrist is closest to the point of origin of the hand.
4. The mouth is INFERIOR to the nose because it is lower in direction to the nose.
5. The thorax is SUPERIOR to the abdomen because it is located above the abdomen.
6. The thumb is DISTAL to the ring finger because it is far away from the ring finger.
7. The sternum is ANTERIOR to the heart because it lies in front of the heart
8. The skull is SUPERFICIAL to the scalp because it is close to the body surface.
9. The ears are LATERAL to the nose because it is towards the middle line of the nose
10. Dorsal refers to the BACK of the human body, while ventral refers to the FRONT of the human body.
Answer:
c)polymerase chain reaction (PCR).
Explanation:
Because the paleontologist recovered only a bit of tissue and it is very old, it is very likely that the DNA in the sample is very small and part of it is degraded. Anyway, the paleontologist must first amplify the DNA sample to obtain many identical copies of the specific region of the DNA they want to compare. the above is done through a polymerase chain reaction (PCR).
So first transcription takes place which is a RNA that translates DNA Template. So an example would be DNA has AGCGTCAATCTA this will be translated into UCGCAGUUAGAU
Then this message is send off to become a protein with the MRNA which then comes Translation which is the process of converting UCGCAGUUAGAU into a protein and the way it’s done is by this message going through a ribosome and gets translated by TRNA that brings amino acids together to form codons and create your protein.
