Depends, if the biotic factor is a chipmunk or something of that case, its natural habitat is a rock, which is biotic. but...if the animal is something like a deer they don't need abiotic factors. its your chose to chose but I'm leaning more twords false because not ALL biotic factors cant go without an abiotic factor
Answer:
A DNA molecule produced by combining DNA from different sources is known as recombinant DNA.
Explanation:
Recombinant DNA (rDNA) can be obtained by coupling DNA fragments from different sources, a process that is performed at the restriction site level and uses enzymes.
Once rDNA has been designed —cutting out fragments of DNA that are then reassembled— it must be brought to a specific location in the cells, to be copied and expressed, using means of transport called vectors.
<u>DNA recombination</u> is performed in biotechnology laboratories specialized in the manipulation of genetic material.
The other options are not correct because:
- <u><em>Mutant or mutated DNA</em></u><em> is a DNA molecule with an alteration of its nitrogenous base sequence
</em>
- <u><em>Hybrid DNA</em></u><em> is a variant of recombiant DNA, in which only two DNA molecules from different sources are used.
</em>
- <u><em>Polyploid</em></u><em> refers to cells containing the genome of different species.</em>
Answer:
Yes because we use our brain to write, read, draw, drive a car, or pretty much anything we do. Even sleeping our brain is working. But at a slower pace. The brain never stops working.
Explanation:
lactobacillus is responsible for producing lactic scid. It is broken down in two groups, hermofermentative species and hetorfermentative species.
Answer: vertebrates have a skeletal structure with a spinal column or backbone. Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull. Due to the lack of a supportive system, a majority of invertebrates are small.
