<h2>
Answer:</h2>
Antagonistic.
<h2>
Explanation:</h2>
- Muscles generally work in groups or pairs.
- Muscles are connected to bones via tendons, these tendons and muscles help in movement of a joint.
- When a muscle is put in contraction, usually only one bone moves. For example on contraction of biceps of the arm contracts then the radius moves but the scapula does not move.
- This type of muscle action is called antagonistic muscle action. In which the muscle which is working is called the prime mover or agonist and the relaxing muscle is called the antagonist.
Result: The muscle action in which a muscle works against another muscle is called antagonistic.
Answer:
Evidence of fossil apes and hominids in both East and West of the great rift valley
Explanation:
<em>The East Side Story hypothesis opined that a tectonic plate movement created a seismic split in the earth, thus deepened the rift valley and created a geographical barrier between the east and the west of the great rift valley. The barrier created a kind of geographical isolation between the ancestors of hominids, dividing them into two with each population taking different evolutionary paths. </em>
<em>Thereafter, the ancestors in the western side of the rift valley evolved into the chimpanzee's family while those in the eastern side ultimately evolved into humans. </em>
<u>Thus, providing the fossils of apes and that of hominids in both East and West sides of the great rift valley will render the hypothesis invalid.</u>
Answer:
t describes Linus Pauling's contribution to the understanding of DNA structure?
Having first discovered the spiral shape of proteins, Linus Pauling used x-ray technology to hypothesize that the DNA molecule consisted of two consistently spaced strands that formed a spiral shape.
Linus Pauling studied DNA base pairing.
Having originally studied proteins, Pauling proposed that DNA was a three-chained helix with a sugar-phosphate backbone at the center and bases sticking out from the backbone.
Linus Pauling conducted experiments to prove that DNA carried genetic information.
