The correct answer is B
Subduction of a ocean plate.
Aleutian islands extend westward from southern Alaska to form the northern boundary of the Pacific Ocean when the Pacific plate gets subducted under North American Plate at a dip of 45 degrees. The pacific is an oceanic tectonic plate that lies beneath the Pacific Ocean. And thus the correct answer is option B
Answer:
The correct answer is option d) "Silencer".
Explanation:
Gene silencing is the regulation of a gene expression that results in avoiding the expression of a gene during a certain period of time. A silencer is a DNA sequence that produces gene silencing. In this example the researcher founds that a gene is not longer regulated in all cells and the gene is still transcribed and translated into protein. The mutation responsible of this it is likely to be occurring in a silencer, avoiding gene silencing of the studied gene in all cells.
Answer:
Explanation:
ATP can be described as the unit for energy. Cellular processes that can involve ATP/energy are
1) Respiration: This involves the cells obtaining ATP by means of combining oxygen and glucose.
2) Metabolism: This is the building up (anabolism) and breakdown down (catabolism) process. Generally, anabolism requires ATP while catabolism releases ATP.
3) Active transport: This requires ATP to move substances or molecules across the cell membrane from a region of lower concentration to a region of higher concentration.
4) DNA replication: ATP is required to sustain replication of DNA at the replication fork during.
5) processes in the cell cycle: ATP is required for the S phase and the mitotic phase of the cell cycle.
6) Ion transport: Ion transport also requires the use of ATP to transport ions across the membrane of cells
Answer:
An enzyme is a protein, and proteins need certain temperatures to function optimally, or even function. Temperature may unfold the protein and may stop its functioning, or it may fold the protein into the correct formation to function. But by the way your question asks, EXCESS heat would denature the enzyme and cease function.
Explanation:
They have a coarse-grained texture.
