Answer:
The area between 200 and 1,000 meters (656 and 3,280 feet) is the mesopelagic or “twilight” zone.
Explanation:
Light intensity in this zone is severely reduced with increasing depth, so light penetration is minimal. About 20 percent of primary production from the surface falls down to the mesopelagic zone.
The features that <span>distinguish animals from organisms in other multicellular kingdoms are that a</span>nimals are ingestive heterotrophs.
The elements are pure forms of matter that cannot be broken down into simpler substances.
Answer: The genotype for the parent organism whose genotype is unknown is Ff.
Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.
The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).
A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).
Ff x ff = Ff, Ff, ff and ff.
Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.
