Without an agent doing work, heat will always flow from a hotter to a cooler object. Two objects<span> of different temperature always interact. There are three different ways for heat to flow from one object to another. They are conduction,</span>convection<span>, and radiation
^^Answer for 3 and for question 4 is
The hot cup has more air flowing around it to cool it down
meanwhile the cold cup has COLD air flowing around it so it would jst do nothing in a result of the cold cups cool temputure to increase
I really hoped this helped and have a great day :)</span>
<em>The answer is (C) The chromosomes , because chromosomes contain genes.</em>
Seeing that our species is constantly evolving, maybe it is starting to get more uncomfortable to walk on all fours.
Answer:
B. The bacteria can cut the viral DNA at its specific restriction site but protect their own chromosomal DNA by modifying its bases and blocking the restriction enzyme.
Explanation:
There are two main reasons why bacteria cuts the viral DNA sequence but not its own.
1) There are specific restriction sites in the genome sequence of bacteriophage that restriction enzymes identify and target. These restriction sites are not present in the genome sequence of bacteria.
2) Even if sometimes the bacteria has a sequence resembling to bacteriophage and has the restriction site, still bacteria prevents the cleavage of its own chromosomes by methylating the bases of the restriction sites. When restriction site is methylated, bacteria just cannot chop it down that prevents it overall from degradation(please see the figure for better understanding).
Note: <em>Although option A can also somehow fit but option B is the perfect option because of the reason no 2.</em>
Hope it help!
Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10 thousand years ago. It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems and as "the total of arrangements, activities, and inputs that people undertake in a certain land type. Land use is one of the most important drivers of global environmental change.
