<span>Point mutations are of two types: Substitutions of bases that are the change of one base of DNA by another. And Transitions that are replaced on a pyrrhic basis by another pyrrhic or a pyrimidine by another pyrimidine. Transversions: substitution of a pyrrhic base by another pyrimidine or vice versa. These mutations are negative because they affect only one of the nucleotides, and therefore, only one triplet of bases are affected. When the mutation does not affect the individual it is a silent mutation. Chromosomal mutations Changes in the structure of the diploid chromosomes, where one of the chromosomes has a mutation, will have another normal. They can hinder the process of meiosis in the carrier since it hinders the correct pairing of the homologous chromosomes. It would produce an unfeasible offspring or with mutations.</span>
Answer:
C. Plants that do not require water?
Explanation:
This is definitely not a benefit of genetically modified foods lol
A possible reason for the transition of algae from unicellularity
to multicellularity would be the evolution of multicellularity allowed algae to
develop traits that keep them close to the land and thus a source of nutrients.
The correct answer between all the choices given is the last choice. I
am hoping that this answer has satisfied your query and it will be able to help
you in your endeavor, and if you would like, feel free to ask another question.
Answer:
A. A thick, waxy covering to prevent evaporation.
Explanation:
Because the desert is usually dry and hot, plant that live in these ecosystems need to adapt to the environment to prevent the loss of water. Water escapes from plants through their leaves as a result of photosynthesis. Desert plants have special adaptations to at least reduce the loss of water and one of them is the thick waxy covering of the leaves to seal in the water.
Answer:
The lens with 4x magnification or the lowest power objective
Explanation:
When you use the low power objective, you have a wider field of view. This would make locating the specimen a lot easier than it would be if you used one with a higher magnification. Once you focus the microscope using the low power objective, you can switch to the higher magnification lenses.
