the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
I can’t answer how lichens arrive in a barren landscape but I can answer the 2nd part
Lichens grow when exposed to water. When wet, lichens begin to photosynthesize.
Explanation:
Incomplete dominance is an intermediate effect of the dominance where the allele for a trait does not express its complete effect of a paired allele as a result both the alleles show their equal effect on the trait.
The generations are produced having a third trait as observed in the case of snapdragon flowers. In the case of flowers
The allele which
1. Determines the red color will be- R
2. Determines the white color will be- r
The monohybrid cross will have parents with genotypes:
1. Red flower- RR
2. white flower-rr
The F₁ generation will have offsprings with genotype-
RR X rr = Rr (Pink flower)
The F₂ generation will have offsprings with-
Rr x Rr= RR, Rr and rr.
Answer:
oxygen and carbon dioxide
I believe the correct answer among the choices listed above is option A. Parasitism is the kind of interaction that is shown here. Parasitism is a kind of relationship where one feed off the other. Fleas here are referred to as the parasite and the dog is the host.
