<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.
</em>
Answer: C
Explanation: All organisms someway somehow must compete for essential resources.
Answer:
<em>The correct option is D) need to be aware that if any of his garlic plants became diseased, it could very likely infect the entire crop</em>
Explanation:
If cloves from a bulb are taken and grown, then the plants formed will be identical to each other. As a result, there will be no genetic varieties in the garlic plants being produced. Hence, when a diseases eradicates, it will affect the entire plants of the garden as they would be genetically identically, Variations would have allowed some of the plants to be resistant for the disease and hence some of the plant species could be saved by genetic variations.
