Answer:
Energy is lost at several levels from the body of an organism. Two of the phenomenons through which energy is lost are
Conduction:
When a body is in contact with another body, energy is lost in the form of heat. For example, if we sleep on a cold floor, energy from our body would be lost to the floor in the form of heat,
Decomposition:
Energy is lost when cells in a body die and energy is required for decomposition also.

Answer: B. TEFKAGSAKGATLFKTRCLQ
D. TEFKAGSAKGATLFKTRCLQ
A.TEFKAGSAKKGATLFKTRCLQ
E. TEFKAGSAKKKGAGATLFKTRCLQ
C. TEFKAGSAKLGATLFKTRCLQ
Explanation:
In complementary base pairing, the G pairs with C, and A pairs with T. Given that this be the rule, the complementary nucleotides for your sequence would be as follows: CGATTAACGTAGGCA.
With regards to proofreading, mutations in cell division occur once in around every 100,000 base pairs. If this happens, the enzyme that pairs the nucleotides to form DNA, called DNA polymerase, detects the error and moves back along the strand, it then cuts the incorrect nucleotide and replaces it with the correct one, fixing the error and continuing with the DNA synthesis.
This process corrects the majority of errors in DNA synthesis, but some errors can still be missed by the DNA polymerase, this is then rectified by a protein complex which binds to the incorrect pairing until anther complex, comes along and cuts that particular section of DNA out, which is then replaced by a new section of correct nucleotides synthesized by the polymerase enzyme, the two sections at either end that were cut is then sealed by ligase, an enzyme which essentially "glues" the DNA stands back together.
My apologies for the long answer, I hope I answered your question and that you understand it well enough.
Answer:
d. eon, era, period, epoch
Explanation:
The geological time scale has been made so that the scientists can have a practical system about the classification of geological time, thus everything that has happened throughout it. The geological time unites have been defined in accordance with important events that have happened, thus marking their end or beginning. These events can be mass extinctions, catastrophes, climate patterns, domination of certain species etc. The longest of these time units is the eon, lasting for more than half a billion years, and up to 2 billion years. The era comes as the second longest time unit, lasting for several hundred million years. The period lasts for several tens of million years, and the epoch is the smallest unit, lasting for few million years, or several hundred thousand years.
