The answer is <span>Cyanobacteria are photoautotrophs.
</span><span>Cyanobacteria /saɪˌænoʊbækˈtɪəriə/, also known as Cyanophyta, is a phylum of bacteria that obtain their energy through photosynthesis. The name "cyanobacteria" comes from the color of the bacteria.</span>
I think this is what you're asking.
Examples of Inherited Traits:
Attached or Free Earlobe. If you look closely at your earlobe, it might be a smooth line, or slightly dangly (free).
Allergies. The most common one I think is gluten.
Answer:
A.
Explanation:
in DNA, G matches with C and A matches with T. G cannot match with G, A cannot match with A, etc.
After hundreds or even thousands of generations both alleles for sickle cell anemia are still common in those of African ancestry. This is supported by two mechanisms: heterozygote advantage and gene flow.
Heterozygote advantage
When an allele is said to be heterozygous, it is carrying one copy of a gene. For example if one carries a copy of sickle cell allele, it will stay in the population even after many generations — natural selection will not be able to remove it and it will be passed on through generations. So, having one copy of that allele is advantageous but not deleterious.
Gene flow
With humans migrating throughout the different parts of the world, sickle cell allele is passed from one person to another or in different populations. It is actually advantageous to have one copy of this allele especially if there’s malaria in the area, which the allele is resistant.
