Conjugation is the direct transfer of DNA from one bacterium to another.
Bacteria can exchange genetic information through three different mechanisms; conjugation, transduction, and transformation. Bacterial conjugation involves the transfer of a plasmid from one bacterium to the other, through cell-to-cell contact. Bacterial transduction is performed through bacteriophages. Bacterial transformation refers to the process of moving genetic elements to various positions of the genome.

Answer:
Letter A - True
Explanation:
Science is in fact limited to topics in which evidence can be gained through experiments and/or observations.
This happens because to realize science, scientists have to strictly follow the scientific method. And in this method, essential steps are observation, formulation of hypothesis and experimentation.
It is also important to note that not all knowledge can be covered by the scientific method, this does not mean that it is not valid, just that it is not science.
Answer: A. Increase in temperature
Coastal upwelling is the process in which the deep water rises above the top most water level as the wind pushes water offshore. Nutrients which are present in the bottom layer get available to organisms living in the uppermost layer. The deeper water lacks oxygen because the decomposition of organic matter at the bottom of the water body consumes up available oxygen. Also, because of these water layer turnover will result in thermocline: temperature variation among the layers of water. Bottom layer water because of such decomposition processes will have more temperature when this water rises in the upper layer due to upwelling this will increase the temperature of the upper layer.
