Answer:
The correct option is C) cytosolic, endoplasmic reticulum
<em>New membrane phospholipids are synthesized by enzymes bound to the cytosolic side of the endoplasmic reticulum membrane. </em>
Explanation:
Synthesis of proteins that are destined to membrane or exportation starts in the cytoplasm with the production of a molecule portion known as a signal aminoacidic sequence. This signal sequence is located in the amino extreme of the synthesizing protein, and when it reaches a certain length, it meets the signal recognizing particle. This particle joins the signal sequence of the protein and leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building. When they reach the membrane of the endoplasmic reticulum, the signal recognizing particle links to a receptor associated with a pore. Meanwhile, the ribosome keeps synthesizing the protein, and the enlarged polypeptide chain goes forward the reticulum lumen through the pore. While this is happening, another enzyme cuts the signal sequence, an action that requires energy from the ATP hydrolysis. When the new protein synthesis is complete, the polypeptide is released into the reticulum lumen. Here it also happens the protein folding (which is possible by the formation of disulfide bridges of proteins are formed) and the initial stages of glycosylation (the oligosaccharide addition). The newly synthesized proteins get packaged into vesicles that take them to the Golgi apparatus.
In the Golgi complex, proteins suffer their final association with carbohydrates and lipids to originate glycoproteins and glycolipids. Once these processes are done, the glycoproteins and glycolipids are packaged again into new vesicles that drive them to their final destiny.
Answer:
a. The corn borer must have or generate (by mutation) heritable variation in resistance to the toxic protein.
b. The resistant corn borers must survive better or reproduce more than nonresistant corn borers.
Explanation:
When there is a change in the surroundings of organisms, some genetic variations become beneficial to the organisms. Natural selection favors the organisms having these genetic variations.
The development of resistance in the corn borer population requires the presence of the gene for the resistance in the population. If there is no gene already present in the population, there should be a mutation to give rise to such gene/s. The corn borers having this gene should be able to survive better in the presence of the toxic protein and should leave more progeny in order to increase the frequency of the gene in the population over the generations.
The Mediterranean sea stretches 2,400 miles East to West from the coast of the Middle - east to the Strait of Gibraltar.
The average width is 450 miles while the widest point is 990 miles.
The Mediterranean sea is a large body of saline water between Europe, North Africa and Asia. It is connected to the Atlantic ocean in the west via the Straight of Gibraltar.
The Mediterranean basin was home to some of the earliest human civilizations in history.
Answer:
Explanation:
Due to the Sun's massive size, its large gravitational pull causes the planets and other objects in the solar system to orbit around it. In orbit around the Sun are the eight planets along with their moons, dwarf planets and many much smaller objects like asteroids and comets.
