Answer:
combines genes from organisms of different species in a lab
Explanation:
Recombinant DNA technology involves the process of joining the genes (DNA) of different multiple species in order to insert into another organism (host). Recombinant DNA technology has many applications in genetic engineering.
One example of Recombinant DNA is the synthesis of Insulin in bacteria cell where a human insulin gene is first inserted into a plasmid vector, then inserted into a bacterial cell that uses its expression abilities to transcribe and translate the gene into INSULIN protein.
This procedure is usually conducted in a laboratory with the use of certain laboratory equipments.
Answer:
Monkeys have a prehensile tail that allows them to grab and hold onto tree branches - structural
Moose make mating calls to locate potential mates - behavioral
Whales are covered in a thick layer of blubber, insulating their bodies in cold ocean waters - structural
Humans have five toes on each foot to help them maintain balance - structural
Many birds migrate south for the winter in search of food - behavioral
Explanation:
The structural adaptations are adaptations that help the organisms to survive in their environment through development of physical traits that give them an advantage. Such adaptations are the thick layer of blubber of the whales, the five toes of the humans, prehensile tail of the monkeys, rotational toe of the clouded leopard, long of the giraffe etc. The behavioral adaptations are adaptations that help the organisms to survive in their environment, but they manifested through their actions, not their physical traits. Such adaptations are the mating calls of the moos, the migration of the birds in winter, the hibernation of the bears etc.
Answer:
Many scientists favor the RNA world hypothesis, in which RNA, not DNA, was the first genetic molecule of life on Earth. Other ideas include the pre-RNA world hypothesis and the metabolism-first hypothesis. Organic compounds could have been delivered to early Earth by meteorites and other celestial objects
Energy is released to be used by a cell when a phosphate group is <u><em>Removed from ATP to form ADP.</em></u>
Answer: <em>C. Removed from ATP to form ADP
</em>
Explanation:
Three important energy carrier molecules in a cell are: ATP (Adenosine triphosphate, NADPH (Nicotinamide Adenosine Dinucleotide Phosphate) and FADH2. All the three carrier molecules play an important role in cellular respiration and photosynthesis.
One NADH molecule is equal to 3 ATP molecule while 1 FADH2 molecule is equal to 2 ATP molecule. During the active process, ATP is used as a form of energy because ATP dephosphorylates to ADP and Inorganic phosphate, Pi and release energy.
