Organisms must be able to adapt to a changing external and internal environment. An organism's ability to maintain a stable internal environment is known as homeostasis. How does a cell's membrane help an organism maintain homeostasis? Cell membranes control the substances that enter or leave cells.
Gel electrophoresis is a process or a technique in which fragments of DNA are separated in terms of their sizes.
<em><u>The restriction enzyme is mixed with a DNA sample before the process. The restriction enzyme cut DNA at specific points into fragments which can then be separated based on their sizes on an agarose gel.</u></em>
When current is applied to the gel DNA move towards the positively charged electrode since DNA is negatively charged, with shorter fragments migrating faster through the gel in comparison with large fragments.
Answer: CO2 was the big driver of global warming at the end of the Ice Age." ... Comparing the global set of temperature records with the levels of CO2 in the ancient air bubbles trapped in ice cores reveals that global average temperatures started to rise at least a century after CO2 levels began to creep up
Yes the earth is changing due to the plate tectonics because when the earth ah earthquakes and all that kind of stuff here comes earth and reshapes it.
Since you did not give a list of choices,here are some reasons why l<span>iving cells cannot use heat to provide the activation energy for biochemical reactions: </span> >Heat can never be used to do work. >Heat is not readily available to all living cells. >Heat doesn't provide the activation energy for their reactions.
