the first one would be the correct answer
The diagram of the carbon cycle given here explains the different processes that occur within it.
Explanation:
1. In G label of the cycle, the process taking place is greenhouse emission where carbon is released in the air by the man made fossil fuel using machines and factories.
2. The energy transformation that is taking place here is that the energy is going from being actively used for human consumption to the static energy which goes into the environment.
3. This process sends the carbon from the environment back to the environment so in theory it is a recycling process only.

Answer:
The correct option is A. they evolved from land mammals.
Explanation:
Evolution can be described as a process through which organisms in a species change over a period of time due to the natural selection of the environment. Those organisms that have many similarities in their functions or structures are considered closer to one another and have the same common ancestors.
The properties mentioned in the question about cetaceans resembles the properties of land mammals. For example, cetaceans lack gills and breathe air. Land mammals also do not have gills and need to respire for living. The cetaceans have fin bones which are similar to the limb bones in the land mammals. Hence, these observations show that cetaceas have evolved from land mammals.
Answer:
Movement of plates bring changes in the physical features of the earth surface in the following ways.
1) When the earth plates move, formation of ocean occurs.
2) Continents are also the product of plates movement. Earthquake is also caused by plates movement inside the earth.
3) Mountain also formed due to the movement of plates. Volcanic eruptions also occurs due to plates.
