Answer:
Heterotrophs are the organisms which cannot prepare their food on their own like autotrophs instead are dependent on other mode to obtain the organic substances from the environment. This method is common in animal and fungi groups.
Although both fungi and animals are heterotrophs their mode of heterotrophic is different as fungi obtain organic substance b secreting many digestive enzymes which digests the complex biomolecules and the fungi obtain the organic substances whereas the animals swallow or ingest the material and then digests it.
In ocean acidification, dissolving co2 gas increases the ph of the ocean
Allele frequency is determined by looking at the dominant and recessive allele of a genotype.
Using the given, we can come up with the following computation for the allele frequency:
allele A = 100/300 allele B = 50/300 allele O = 150/300
Hence, the frequency of allele A is 0.33 or 33%, allele B is .17 or 17% and allele O is 0.50 or 50%.
12/20 is the answer I think. I hope this helps you!!
