The correct answer is B. In the cytoplasm of the cell.
In addition to on the rough endoplasmic reticulum ribosomes can be found in the cytoplasm of a cell.
Explanation;
Ribosomes are cellular organelles that functions in making of proteins. They contain special proteins and nuclei acids.
Ribosomes can be found in two different spaces in eukaryotic cells; that is, on the rough endoplasmic reticulum and floating in the cytoplasm of a cell. In the cytoplasm they are not bound to anything as they are in the rough endoplasmic reticulum.
Answer:
decrease; an increase
Explanation:
Density is a physical quantity which depends upon two factors mass and volume. Density has a direct relationship with mass while an indirect relationship with volume i.e. if mass will increase then density will also increase but if volume will increase then density will decrease.
The formula for density is mentioned as under:
Density = mass/volume.
Here, in this question the reason why density of sea water will increase if temperature decreases is because a decrease in temperature will result into less movement and therefore lesser space between water molecules and lesser space indicates less volume. Since, volume and density has inverse relationship so less volume will be responsible for increase in density.
When it comes to salinity, an increase in salinity will result into the higher density of sea water. When salts dissolve into the water they add to the mass/weight of the water i.e. mass of the water increases with increase in salinity. Since, mass and density have direct relationship, an increase in salinity will increase the density of water.
Answer:
It's Oxygen.
Explanation:
Some abiotic factors, such as oxygen, are important in aquatic ecosystems as well as terrestrial environments. Terrestrial animals obtain oxygen from the air they breathe. Oxygen availability can be an issue for organisms living at very high elevations, however, where there are fewer molecules of oxygen in the air.
