WINSTONCH [101]3 years ago

Answer:The rocks are smooth due to the water eroding the rocks.

Explanation:

The water slowly takes off minerals of the rocks every time is splashes over them. Over time the rocks bumpy surface would be eroded away giving it a smoother surface.

To give birth to her infant, a woman is asked to push with contractions. which pushing technique is the most effective and safes
lesya [120]

While giving birth to her infant during labor, the safest and the most effective pushing technique taught to a woman during contractions is grasping knees, head elevated and breathing out.

During labor, it is very important for the mother to keep breathing. If she holds her breath, it will put pressure on the vena cava and lead to a reduction in the blood return. The head is kept elevated and the back is rounded which aids the abdominal muscles to help the uterus to push the baby out. Grasping the knees also helps in pushing and encouraging the movement of the infant outside the body.

The process of translation in prokaryotes can occur faster than in eukaryotes because
Nimfa-mama [501]

Answer:

Transcription and translation occur simultaneously in prokaryotes.

Explanation:

Prokaryotes lack membrane-bound organelles and therefore, do not have a nucleus. Transcription and translation occur in the cytoplasm. As soon as the required length of mRNA is being formed, ribosomes join it and start the process of translation. Prokaryotic genes lack introns. The primary transcript formed by transcription in prokaryotes does not undergo splicing.

On the other hand, the process of transcription occurs in the nucleus in eukaryotes while translation occurs in the cytoplasm. The primary transcript formed by transcription in eukaryotes undergoes modifications to remove introns and to add a poly-A tail and 5' cap. Post-transcriptional modifications and spatial separation of two processes in eukaryotes result in slower translation than prokaryotes.

Why does synthetically produced RNase refold incorrectly if the reducing agent is removed before urea removal?
olya-2409 [2.1K]
<h2>Disulfide bonds interaction </h2>

Explanation:

  • The high concentration of urea causes unfolding of protein and thus results in loss of function of a protein. The urea interacts with the protein and prevents the folding of a protein.
  • During oxidation, the disulfide bonds that are required for proper functioning and stabilization of protein are formed, while in the presence of urea, the disulfide bonds are not positioned correctly. The protein oxidation results in covalent modification of a protein that results in the change of physical and chemical properties of a protein.
  • The change of physical and chemical properties of protein after oxidation and in the presence of urea cannot be modified even after the removal of urea. Thus, protein does not fold properly.
  • Hence the right answer is "disulfide bonds are not positioned correctly rather than week bonding interaction"
