How are new alleles created? Occasionally, DNA mutations occur in germ cells – cells destined to become eggs or sperm. In this case, the DNA mutation is copied into every new cell of the growing embryo following fertilisation. ... If the mutation affects a gene, it will result in a new version of that gene – a new allele.
I'm sorry, but I would need to see the options.
Sunlight (it is used by zooplankton which are the bases of all life in the marine ecosystem)
Answer: In the atmosphere, nitrogen exists as a gas (N2), but in the soils it exists as nitrogen oxide, NO, and nitrogen dioxide, NO2, and when used as a fertilizer, can be found in other forms, such as ammonia, NH3, which can be processed even further into a different fertilizer, ammonium nitrate, or NH4NO3.
Explanation:
The answer to your question A link between green algae and land plants has been clear to biologists for. The remainder of Chlorophyta constitutes a monophyletic group. This major bifurcation in green plant evolution implies a single common ancestor to the two lineages, but, of green algal phylogeny, which is reflected in modern classification.<span>
