Transduction. Transudction is the process where foreign DNA is introduced into a cell by a virus or viral vector. An example would be a viral transfer from one bacteria to another.
Answer: They must be randomly chosen, meaning that each member of the larger population has an equal chance of being chosen. They must be large enough so as not to skew the results. The optimal size of the sample group depends on the precise degree of confidence required for making an inference. Simple random sampling is the basic sampling technique where we select a group of subjects (a sample) for study from a larger group (a population). Each individual is chosen entirely by chance and each member of the population has an equal chance of being included in the sample.
Hope this helps... Stay safe and have a great day/night!!! :D
Answer:
Plate tectonics
Explanation:
Plate tectonics is a scientific theory describing the motion of seven large plates and the movement of a larger number of smaller plates of the Earths lithosphere.
Considering the following;
I. Heat is not readily available to all living cells.
II. Heat at excessive amounts denatures proteins.
III. Heat does not provide the activation energy for their reactions.
IV. When a critical temperature is reached, proteins no longer function
Answer;
I and IV
Explanation;
Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.
Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.
Answer:
Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. And most importantly decomposes make vital nutrients available to an ecosystem primary producers- usually plants and algae.
