Answer:
A rock is a collection of minerals. In a cooling lava, mineral crystals do not have time to form and are very small. The chemical composition will be the same as if the magma cooled slowly. Existing rocks may be heated enough so that the molecules are released from their structure and can move around.
Explanation:
False. It can and will dissolve in water.
Answer:
<u>Mutations</u>
Explanation:
The answer is mutations because it is the one process that leads to new lifeforms evolving!
Answer: The peptide sequence that is essential for protein insertion, orientation in membrane and for travelling into particular organelle is called a topogenics.
Explanation: Integral membrane proteins are found in all cellular membranes and carry out many of the functions that are essential to life. The membrane-embedded domains of integral membrane proteins are structurally quite simple, allowing the use of various prediction methods and biochemical methods to obtain structural information about membrane proteins.
<u>Answer:</u>
Considering the nitrogen cycle, all organisms depend on bacteria to produce and maintain adequate nitrogen in the environment by eating the plants that contain bacteria which contain nitrogen.
Option: (B)
<u>Explanation:</u>
- Nitrogen is a main element in the nucleic acid of both RNA and DNA which is most important for all living creatures and biological molecules.
- When plants doesn’t get enough nitrogen it doesn’t produce amino acid, without amino acid plant cannot make special proteins.
- Amino acid is building block for DNA which tends to the generation of organism.
- Nitrogen fixation is a process where bacteria convert atmospheric nitrogen to usage form for plant and animals get nitrogen by eating those plants.
