Answer:
Over millenia, these rocks get pushed back into the Earth's mantle, and get pushed into a volcano heating it up and turning it into magma.
Explanation:
Magma is molten rock, meaning existing rocks must be getting melted, the way the melting happens is by the rocks getting pushed into the ground by landforms and penetrating the mantle, this is how the cycle starts all over again.
Answer: its B
Explanation: I answered the same thing.
Agriscience is the right answer :)
Answer:
Birds have a different mating season this evidence will go against the argument and suggest that the birds are actually different species. Generally, two factors seasonal and behavioral identifies the differences among the species. Species generally interbred among the same population of species according to the season and hence they loose mating opportunities. Although being sexually compatible they do not interbreed. Behaviorally, a biological clock in species naturally sets breeding cycle according to the resources availability, suitable nesting sites and mating opportunities. Different species have different seasonal requirements to accomplish this.
Answer:
1- By eating a supplement that enhances the ability of red blood cells to transport oxygen, thereby reducing the oxygen dependence
2- By developing structures that help to support high pressures, thus improving the ability to breathe in deeper marine habitats
Explanation:
Recently, it has been shown that beneficial mutations provided to marine mammals a biological adaptation associated with a higher ability to transport oxygen in red blood cells when compared to terrestrial mammals. This adaptation enables marine mammals to breathe less frequently to obtain the same amount of oxygen.
In birds, the airflow is unidirectional (i.e., inhalation and exhalation are complete), rather than mammals where the air in and out of the lungs. This mode of respiration helps the birds to tolerate the high pressures during flight.
