Answer:
They are important because they help us understand science theories and allows us to dig deeper into science.
The invention of DNA replication through PCR!
Because of this technology, we can now classify organisms based on genetic relatedness instead of the similarity between physical traits. The more we use PCR to identify different organisms across all “kingdoms” the more the previously established family tree of life shifts into something new
The usual mode of stimulus transfer in neuron- to -neuron interactions is CHEMICAL SIGNALLING. One cell interacts or communicates with another cell through cell signally where signal molecules such as hormones carry the information. Neurotransmitters are the chemicals that transfer the signals from one neurons to another.
Answer:С) Cells from two organisms combine.

Answer:
Chemical properties of water are neutral pH and weak ionization while physical properties of water are that it is present in solid , liquid and gas form and it is a tasteless and odorless molecule.
Explanation:
Water is also called universal solvent due to its polar nature. Water has a neutral pH when it is present in pure form but with the addition of salts and other impurities, pH of water changes. Water has weak ionization rate. Water is present in liquid form at room temperature but increasing in temperature , they transform in gaseous state.. Water is a taste less molecule and having no odor or smell.
