Answer:
a) into the ER
b) into the ER
c) into mitochondria
Explanation:
a) This signal is located at the N-terminus of the protein and acts before the internal signal is synthesized for import into the nucleus. When the protein enters the ER, the sequence of the import signal in the nucleus cannot work because the protein would be prevented from interacting with the cytosolic receptors.
b) The signal that is imported into the peroxisome cannot function once the protein was sequestered in the ER.
c) In order for the protein to be retained in the ER, the protein must first be imported into the ER. Without there being no signal for that import of the protein into the ER, that retention signal could not work.
Cyclins and cyclin-dependent kinases are responsible for the progress of the cell through the various checkpoints.
Answer:
genetic modification competitors increase
Explanation:
The fish developed the gills because of <em>genetic modification</em>. Because the fish are now able to swim in deep water, their <em>competitors</em> in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will <em>increase</em>.
I’m pretty Sure it’s A sorry if i’m wrong
Answer:
1. polarity
2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.
