Answer:
TEs are repetitive and mobile elements, thereby it is hard to trace their origins
Explanation:
Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.
Answer:
The correct choice is A)
There will be fewer producers in the area.
Explanation:
Very easy to deduce. A producer in biology of ecosystems is an organism that produces its own food. Another word for a producer in biology is 'autotroph'.
They produce energy directly from the energy given off by the sun or chemicals or both.
Grass (or plants) are producers. They do this with the help of water, converting solar energy into sugar or food, which are usable forms of energy.
So the more grass is consumed, the fewer producers in the area.

The answer is C because the load shouldnt be greater than the effort, it isnt usually, but my best answer to you would be C
