Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features)
They do not influence the salinity level in their environment, they maintain the salinity in their body. If they don't, osmosis will cause their cells to shrink due to the fact that the salinity in the cell is lower than outside the cell. This will make water leave the cells. So they need to get rid of excess salt all the time. Freshwater fish need to retain the salt in their bodies, otherwise the opposite will happen. Salinity level in the cell is higher than outside the cell and this causes influx of water which will make the cell build up turgor pressure. Ultimately they will explode. So fishes in both environments adapted to deal with osmosis.
These microscopic organisms are referred to as pathogens
Answer:
Sugar and nutrients.
Explanation:
Culture media are chemical compositions created in the laboratory that provide all the necessary resources for the creation of microorganisms in vitro. In short, the culture media provide adequate food for microorganisms to grow and be analyzed and studied.
The culture media can have a liquid, solid or semi-solid consistency, however it is important that regardless of cosistence, they all have in their composition sugars (which will provide carbon and energy for the microorganism) and nutrient (so that they grow nourished and strong).
That would be 29 because if u look at all the other years at the end of all the years the number is only a few numbers up from the first number.
