This is because Pangaea explains that once there was one huge country that expanded across the whole world, but it split apart and animals that were once next to each other were drifting apart to other parts of the world where both would survive on both sides.
Answer:
Offspring in F1 generation had yellow-seeded pea plants.
Explanation:
When Mendel used yellow-seeded and green-seeded pea plants as parents plants he noticed that all of the offspring of the first generation (F1) were yellow-seeded plants. In the next following generation (F2), phenotype ratio was 3:1 (yellow:green).
After this observation Mendel conclude that yellow-seeded plants are dominant over green-seeded plants. Since he used purebred plants, genotypes were:
P: AA x aa
F1: Aa Aa Aa Aa
F2: AA Aa Aa aa
AA and Aa are genotypes for the yellow seeds, while aa is genotype for green seeds.
If adding more HCl will double the original amount you get concentrated HCl I think
In negative control, a gene is switched off when a regulatory protein binds to DNA and shuts down transcription.
Answer:
DNA or RNA
Explanation:
There are a number of similarities between viruses and cells. Both are too small to be seen with naked eyes and require a microscope for observation. Both contain genetic material, in the form of DNA and/or RNA. Both of them can replicate, that is, produce more organisms similar to themselves.
