Animals need to consume food in order to obtain energy (just like humans.
Trees are a crucial part of the<span> carbon cycle</span>, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through <span>photosynthesis </span>in order to make energy. This carbon is then either transferred into oxygen and released into the air by <span>respiration </span>or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles andpollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.
Answer:
The trait must make the individual more fit to survive. True
Explanation:
Darwin proposed that genetic variations are present in natural populations. Some genetic traits become beneficial under the changed environmental conditions. The organisms with these genetic traits are able to survive and reproduce better than the organisms that lack them. This results in an increased proportion of the beneficial genetic traits in the population over generations as the individuals having those traits reproduce more.
The presence of antibiotic resistance is a beneficial genetic trait that allows bacteria to survive in the presence of antibiotics. Natural selection favors the bacterial having antibiotic resistance and increases their proportions in the population over generations.
<span>The first enzyme is reverse transcriptase. The concept of
reverse transcription was much unknown at first. A reverse transcriptase is an enzyme used to
generate complementary DNA (cDNA) from an RNA template, a process termed
reverse transcription. It is mainly associated with retroviruses. As it
contradicted the central dogma of molecular biology, which states that DNA is
convert into RNA, which is then translated into proteins.</span>
