The waves do not help scientist
Answer:
The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air
Explanation:
the fundamental problem that an aquatic animals face during its progress to land to save the egg or embryo from parching. So they have developed cleidoic eggs where undeveloped organism stay implanted inside extra embryonic layers, for example, amnions and are secured in egg shells. These eggs have minute pores so embryo can make gas exchange.
This egg shells forestall water misfortune. Interior treatment, however are available in certain sharks, yet it is for the most part a variation of land creatures. Explicit intromittent organs have been created for moving of sperm in to female. In contrast with water , gaseous movement is in land creatures is happen through advancement of lungs which contain numerous alveoli where gaseous exchange is occurred. Decreased surface to volume ratio decrease productivity of gas exchange , not increment.
Thus, The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air
Answer:
Option A
Explanation:
Renewable resources of energy are clean source of energy. They are sustainable as they are readily available, can be used again and again and do not produce any pollution neither during production stage nor during usage stage by an individual.
There are very nations in the world which are oil rich and country itself has no oil reserve. In such scenarios, the dependency of nation on other countries increases. But in lieu to in-house renewable energy resources, country will not import oil from other nations
Hence, option A is correct.
Sink to the bottom because it is more dense than the water.
