Metamorphic rocks, because sedimentary rocks are formed from compressed sand, gravel, dirt, etc. and igneous rocks are formed by cooled magma, but of course each type of rock can be formed other ways. so it leaves us with metamorphic.
I think the correct answer is D Hope this helps
The answer is; The spectrum of a star shifts towards the blue region when the star moves towards Earth.
This is referred to as the Doppler shift effect. As the star moves closer to the observer, the wavelength of light it produces is ‘compressed’ hence changing its relative frequency (just like the pitch of the siren of an ambulance approaching you).
Explanation:
There are two aspects of a reaction:
Thermodynamics:
Combustion of the compound is reaction with oxygen.
The carbohydrates contain more content of oxygen as compared to fats.
Hence, carbohydrates have lot of oxygen content which are already partially oxidized as compared to fats. Hence, combustion of the carbohydrates is a faster process.
Kinetics:
The molecular reacts also shows that the combustion of the carbohydrates is a faster process.
Answer:
circulatory system
Explanation:
it is what makes oxygen circulate
