Some animals get water from water from plants they eat and others drink water.
hope this helps
I'm assuming this question refers to the rate of photosynthesis.
Plants need both light and CO2 to photosynthesize (PHOTOsynthesis means using light to use CO2 to make O2 and other nutrients). If the light intensity were very low, the plant wouldn't have enough energy to photosynthesize much.
You could have all the CO2 in the world, but if there's not enough light, the plant wouldn't be able to photosynthesize.
In short, it'd be difficult to find the ideal CO2 level if the light intensity were very low because the plant needs a certain light level to even photosynthesize. You could only find the ideal CO2 level if you had enough of all other nutrients, and CO2 level was the only variable you were changing.
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>
