The value of a transitional fossil is that it shows the evolutionary steps between species.
Answer:
The correct answer is b) promoter
Explanation:
Promoter is a cis-acting DNA sequence that is position dependent and is present upstream to the transcription start point. This upstream sequence is very much specific and necessary to accurately initiate the transcription.
For example, E.coli promoter consists of two consensus sequence upstream to the transcription start site. So DNA polymerase recognize these sequence and binds to the promoter region. After binding, it starts the transcription of the mRNA.
Therefore promoter is the specific recognition sequence which is required to be recognized by RNA polymerase to initiate the transcription of mRNA.
Single-celled and multicellular both have structures that perform life processes. Cells are the building blocks of life in living organisms. They are crucial in the production of energy and the inherited traits and characteristics of particular organisms. Single-celled organisms are also referred to as Monads, which are composed of bacteria, archaea, and protozoa. Multicellular organisms are plants and animals that perform more complex processes than single-celled organisms. Cells in animals differ from cells in plants, in that plants have the capacity to produce their own food and nutrients for sustenance while animals can't do this.
The correct answer is A. Melting
Explanation:
Melting occurs in solids as these change their state to liquid state, usually due to high temperatures. For example, if one cube of ice is exposed to heat it melts. This physical change implies the solid loss its defined shape and particles in it are not as organized as before.
This process is exemplified by the situation of the oranges because the pyramid of oranges had a defined shape and the oranges were arranged in a defined pattern; however, in the end, this shape changes, and the particles (oranges) are no longer organized in a strict pattern. Also, the distance between particles increases, which also happens when solids become liquids.
