The right answer is C) convection.
Convection (thermal) refers to the transfer of thermal energy within a moving fluid or between a moving fluid and a solid wall. This transfer of energy is achieved by two modes of "elementary transfer" combined that are advection and diffusion.
Convection (thermal) constitutes, with (thermal) conduction and (thermal) radiation, one of the three modes of heat exchange between two systems, and differs from them by the transfer method.
Thermal convection occurs when the body is in direct contact with the fluid.
Answer:
The answer is A
Explanation:
There are certain types of proteins that need to be sinthesized in the rough ERC in order to reach its final destination. These proteins are:
- Proteins that need to be exported from the cell.
- Proteins that need to be docked to either endomembranes or the plasma membrane.
- Hydrolytic lysosomal enzimes.
- Proteins that have a function in the lumen of certain organelles such as the endoplasmic reticulum, golgi or the nuclear envelope.
Hemoglobin doesn't fit in any of these cateogories, given that it is a cytoplasmic protein. Therefore, its synthesis begins and ends in the cytoplasm, where the protein performs its function.
Answer:
c. Proteins and lipids are made on the ER membrane and put in vesicles.
a. Vesicles containing proteins and lipids fuse with the Golgi bodies.
d. The Golgi bodies tag the molecules to signal their ultimate delivery.
b. Vesicles pinched off from the cristernae carry the molecule to its location.
Explanation:
Proteins are made by the ribosome machinery of the rough endoplasmic reticulum. The proteins made need to be packaged before they are sent outside the cell to their location. If the proteins are not packaged and tagged, then they will be degraded by different enzymes present in the cell. So, the packaging of the proteins is done by the Golgi-complex. After packaging is done and tags are added to the proteins, the proteins move to the outside of the cell in vesicles.
Answer:
by the process of photosynthesis
Explanation:
Answer:
Xylem transports and stores water and water-soluble nutrients in vascular plants.
Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
