If the water is salty like in the oceans, as the water freezes the salt is pushed out making the water denser making it sink to the bottom in a current to keep climate cool and the surface currents warm the artic. The way it effects life is, it makes a passageway over the freezing water across so that you won't freeze to death swimming. And it helps migration too. The Sub-zero waters keep algae from growing, which is good because most are hibernation.
I hope this helped!
Answer:
A differential medium
Explanation:
Bacteria require nutrients for growth, and in order to culture (grow) them and study their characteristics, different types of media are used.
A selective media is used to grow a particular group of organism while suppressing another. So a selective media usually has an inhibitory agent, which will inhibit the growth of the undesired group. An antibiotic can be added to a medium to make it selective.
A general purpose medium as the name implies can be used to grow any group of bacteria. It has no inhibitory agent and indicator that differentiates between organisms. An example of general purpose media is nutrient agar
.
A non-synthetic media is made from natural ingredients.
A differential media differentiates between groups of organisms. Example of differential media is MacConkey agar and Mannitol Salt agar. On MacConkey agar, lactose fermenting bacteria turn pink while non-lactose fermenting bacteria are colorless.
On Mannitol Salt agar, mannitol fermenting bacteria turn yellow while non-mannitol fermenting bacteria are colorless. Mannitol Salt agar is also a selective medium. It has a high salt concentration which inhibits certain organisms.
Answer:
i think the answer is 0.00042. i hope this is right
Explanation:
The best answer is A.
Mitochondria are small organelles found floating free in the cytoplasm of both animal and plant cells. They consist of two membranes, an outer and inner membrane which has numerous folds creating layered structures called cristae.Inside the mitochondria, there is found fluid called the matrix
Mitochondria are the powerhouse of cells. Many of the reactions in cellular respiration that take place in the cell occur in mitochondria and thus these organelles are key in the production of energy .
The answer is D! birds have to migrate for winter to find an abundance of food! they learned this over time making it a learned adaptation
