Erosion shapes. Lowest level directs.
Answer:
A and D
Explanation:
Dolphins have a narrow, torpedo-shaped body to swim easily through water. Their strong, paddle-like flippers also aid in strong swimming.
However dolphins do not secrete gases or attach themselves to the bottom of the sea, so the answers are A and D.
Good luck ^^
<h3><u>Answer;</u></h3>
Myxedematous coma
<h3><u>Explanation;</u></h3>
- Myxedema coma is a severe hypothyroidism leading to decreased mental status, hypothermia, and other symptoms related to slowing of function in multiple organs.
- it is a loss of brain function as a result of severe, longstanding low level of thyroid hormone in the blood.
- It is a rare life threatening complication of hypothyroidism.
There are not only one but two correct option, which are A and B.
DNA polymerases begin their synthesis at many points of initiation. Following the binding of specific proteins, the double helix opens to allow startup.
DNA synthesis begins on RNA / DNA primers consisting of primase and DNA polymerase a. The replication continues in one direction: in this sense one of the two strands of the DNA ("direct" strand) is traversed by the enzyme in the 3 '→ 5' direction, which allows the synthesis of another strand in the direction 5 '→ 3'. The DNA-ligases then provide the link between the different fragments of the new DNA.
The synthesis of the other strand ("delayed" strand) is more complex because the enzyme travels this strand from 5 '→ 3'. The primase and DNA polymerase α synthesize 30 nucleotide primers in front of the replication zone, and the DNA polymerase constructs small DNA fragments in the 5 '→ 3' direction (approximately 200 nucleotides; Okazaki). Ribonucleases destroy the RNA / DNA primers of the previous fragment and the fragments are then linked together by DNA ligase.
The theory of plate tectonics evolved from the previous theory of continental drift. Alfred Wegener came up with the latter theory in comparing the coastline shapes of for example eastern South America with western Africa they seemed to fit together. However, there was no mechanism for this until I believe in the late 1960's or early 1970's the theory of plate tectonics was developed which the Canadian geophysicist played a part in J. Tuzo Wilson. The latter theory shows how the mid-oceanic ridges are spreading and the continental margins have the ocean floor subducting.
