DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical method while on the other hand, Polymerase chain reaction (PCR<span>) is a technique used in molecular biology to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.</span>
Answer:
The correct option is C. Drawing a conclusion
Explanation:
The scientific method can be described as a method through which all the scientific questions are tried to be answered.
The scientific method begins with a question. To answer the question, a hypothesis is generated. Experiments and observations are made to test the hypothesis. Based on the data from experiments and observations, conclusions are drawn. Hence, the statement 'based on the data, we determined that plant growth is affected by the type of soil' best illustrates a conclusion.
Answer:
B) and D) are the correct answers
Explanation:
Hadalpelagic zone contains life such as amphipods
, snailfishes and cusk-eels.
Epipelagic zone is the ONLY zone where visible light and algae can be found. Lower than that the amount of light is insufficient for plants to carry out photosynthesis.
The mesopelagic zone has a diverse biological community that includes unique organisms adapted to live in a low-light environment including fish like
the blobfish, bristlemouths or the tasselled anglerfish.
Explanation:
no, we can not see radio waves. radio waves have the longest wavelength out of all the waves on the electromagnetic spectrum. we can only see visible light, which is towards the middle of the spectrum. the waves below or above visible light on the spectrum have wavelengths that are too long or short for the human eye to detect.
