Answer: external fertilization
Explanation:
External fertilization is the process of fertilization in which the male sperm cells fuses with the female egg cells outside the body of the female. This type of fertilization is used by the organisms which live in the water body.
The salmon is a fish species which utilizes external fertilization. In the case of salmon, the female salmon drops the eggs in the bottom of the water which are fertilized by male salmon after secreting their sperms over these eggs.
Answer:
maintain homeostasis in eukaryotic cells.
Explanation: these are two roles in maintaining homeostatic in eukaryotic cells
1. Membrane Production: The rough ER is responsible for producing the phospholipids and proteins that make up the cell's membranes. These membranes are essential for compartmentalizing the cell and regulating the movement of substances in and out of the cell. For example, the rough ER helps in the production of the plasma membrane, which controls the exchange of molecules between the cell and its environment.
2. Protein Production: The rough ER is studded with ribosomes, which are responsible for protein synthesis. The ribosomes on the rough ER synthesize proteins that are destined for secretion, insertion into the cell membrane, or transport to other organelles. These proteins undergo folding and post-translational modifications in the rough ER, ensuring their proper structure and function. For example, the rough ER produces enzymes that aid in digestion and hormones that regulate various body functions.
By facilitating membrane and protein production, the rough ER helps maintain the integrity, structure, and function of eukaryotic cells. Without these processes, cells would not be able to carry out essential functions, leading to cellular dysfunction and potential health issues.
The rough ER's main function is to synthesize and modify proteins destined for the cell membrane or for export from the cell, a process that is crucial in maintaining homeostasis in eukaryotic cells. This protein synthesis and distribution are crucial for cells' life, growth, and responses to the environment.
The primary function of the rough ER is the synthesis and modification of proteins that are destined either for the cell membrane or for export from the cell. This process is aided by ribosomes that attach to the ER, giving it a rough appearance. The produced protein is typically synthesized within the ribosome and then released inside the channel of the rough ER, where sugars can be added to it (glycosylation) before it is transported within a vesicle to the next stage, the Golgi apparatus.
This protein synthesis by the rough ER plays an important role in maintaining homeostasis in eukaryotic cells. It helps ensure the cell has the required proteins to function properly and influences the balance of protein production and distribution, crucial for cell life, growth, and responses to the environment.

salinity
Answer: Salinity
Explanation:
Salinity can be natural in some of the natural biomes such as sea water and estuaries. There are some aquatic species which are capable of adapting and surviving in the change in concentration of salt. Those species which are incapable of adapting in the saline environment they decline in number, migrate to different location or even they may extinct. Organisms can tolerate in conditions like changing temperatures, density, and depth.
On the basis of the above description, salinity can be the number one factor for determining the fact that living things can be survive in a body of water.
