The freezing temperature of water depends on the amount of dissolved salts salinity. Salt is expelled as the ocean water freezes to form sea ice. This creates dense brine that sinks and flows down the continental shelf of Antarctica to form Antarctic Bottom Water the densest water in the open ocean.
Answer:
The correct answer is- Transduction
Explanation:
There are three processes by which genetic material of one bacteria can pass to the other bacteria and these processes are transformation, conjugation, and transduction.
In transduction bacteriophage( virus that infects bacteria) is responsible for the transfer of genetic material of one bacteria to another bacteria. When a virus infects one bacteria its genetic material divides with the bacterial DNA and sometime during making new phage particles part of bacteria DNA gets packed in viral capsid.
When that virus infects another bacteria the genetic material of other bacteria gets incorporated in its host genome and this process is called transduction.
Answer: A Civil Engineer benefits from the knowledge of physiology because it helps to effectively design buildings to fit human beings adequately. That is, the height of a doorway must effectively take most people.
Explanation: This is when we talk about Ergonomics, that is the environment must effectively fit the user.
Answer:
The volcanic activity led to the release of large amounts of carbon dioxide at the end of the Devonian period
Explanation:
Devonian period is refereed as the Age of fish. It is also called an era of mass Extinction. During the end of Devonian period most of the terrestrial animals were extinct from Earth. Another big feature of Devonian period was massive volcanic activity which contributed to the release of carbon dioxide in the environment.
Answer:
<em>The highest grade metamorphic rocks will be formed at high temperatures and high pressures.</em>
Explanation:
Metamorphic rocks can be described as the type of rocks which are formed by a change in the form of the existing rocks. In other words, metamorphosis of igneous, sedimentary or existing metamorphic rocks leads to the production of metamorphic rocks. High temperature and pressure are required by the rocks to change its form and develop into metamorphic rocks. Temperatures usually more than 320 degree Celsius are required for high-grade metamorphism.
