<u>Answer:</u>
<em>The intertidal zone is a region of extreme conditions and the organisms should have special mechanisms to cope up with the extreme conditions.
</em>
<u>Explanation:</u>
Low tides expose an intertidal zone to air while high tides cover the intertidal zone with ocean water. When exposed to air the intertidal region is <em>directly exposed to the sun and there will be high temperature. </em>
Thus the animals have to cope up with the extreme heat and also have to face colder environment when under the sea. <em>Since there is change in salinity the organisms have to handle this as well.</em>
Some animals with shells close their shell tightly to seal moisture. Animals like <em>snails and crabs have thick outer covering to prevent water loss by evaporation. </em>
Organisms like leaf barnacles cluster together to avoid individual exposure. <em>Animals like sea stars cling to the rocks to avoid being washed away by the waves.

61% of emerging diseases is caused by zoonotic pathogens
Explanation:
Out of total emerging diseases zoonotic contributes 61%, that are originated from wildlife. The rate is increasing due to growth of human population, its mobility, frivolous, cultural and their socioeconomic purposes. Air is the major source for spread of infectious diseases. Zoonoses are generally caused by bacteria, viruses and pathogens that are blowout between animals and human beings. Modern zoonoses are Ebola virus and salmonella. One of such direct zoonoses is rabies, that is transformed directly from animal to human.
Answer:
Well you began with 2 DNA replication
Explanation:
Answer:
Adaptations and selective breeding, if that is a choice for you.
Explanation:
Hypotonic, isotonic, hypertonic
these terms are connected to the solution concentration. hypotonic solution is the solution with low concentration (lower than the concentration of particles in the living cell of an organism). if you put a cell in such solution, that cell would baloon because of the water migrating inside willing to rebalance the concentrations. isotonic solution is the solution with concentration of particles equal to the concentration inside a cell. hypertonic solution has concentration of particles higher than a cell and putting cell in this solution makes it shrivelled because of the water flowing outside (willing to rebalance concentrations again).
that's a phenomenon of osmosis.
