When the water evaporates from the ocean and becomes water vapor, its energy level increases. The change in energy is positive. Water in the ocean is in liquid state. The molecules of water on getting the energy from the Sun increase their energy of movement and become gas. This change in energy is called the latent heat of vaporisation of water. Hence it can be said that a change in state of matter from liquid to gas causes a net increase in its energy.
The Answer is A.) Cytoplasm
The two sources of heat in the earth's interior are-
A. The leftover heat from formation and radioactive decay
Explanation:
The leftover heat from the time when the planet was formed, which has not yet been lost, is a source of internal heating of the earth. There are various radioactive elements present deep inside the earth and they are decaying slowly and gradually and emit heat into the earth's interior.
Answer:
Yes.
Explanation:
Yes, small plants began to grow along the remaining soil because of the presence of seeds in the soil that sense suitable environmental condition and come out of the soil. The ashes of burn trees have huge amount of nutrients in the form of minerals that triggers the growth of small plants. After the destruction of forest, new plants grow on that land, this type of phenomenon is called ecological succession.
Answer:
The correct answer is option d) "Silencer".
Explanation:
Gene silencing is the regulation of a gene expression that results in avoiding the expression of a gene during a certain period of time. A silencer is a DNA sequence that produces gene silencing. In this example the researcher founds that a gene is not longer regulated in all cells and the gene is still transcribed and translated into protein. The mutation responsible of this it is likely to be occurring in a silencer, avoiding gene silencing of the studied gene in all cells.
