Answer/Explanation:
An important way of selecting for bacteria carrying specific recombinant DNA is to add a resistance gene (such as antibiotic resistance) to your gene of interest. That means that any bacteria that carry your DNA will be resistant to a specific antibiotic (in this case streptomycin). Therefore, you can grow your bacteria on plates with streptomycin, and in theory, the bacteria will be unable to grow if they don't have the resistance gene and your gene of interest.
Here, strain A does not grow on streptomycin plates, but strain B now has 100 colonies. This suggests strain B can grow on streptomycin, meaning it is resistant.
Strain B is therefore the streptomycin resistant master plate strain.
It alter's into a metamorphic rock known as slate.
C) Increases genetic diversity is not an advantage of asexual reproduction
Plants absorb water through tiny hairs that cover the surface of the roots. Water is absorbed by osmosis — the movement of water molecules through a semipermeable membrane from an area of high concentration to an area of low concentration. Transpiration, the release of water vapor through the leaves, is the main force that controls the movement of water through a plant. Transpiration is regulated by the stomata, tiny pores on the underside of leaves that open and close to release water vapor and exchange carbon dioxide and oxygen. When the plant’s water concentration is high, the stomata open to release excess water; when the water level drops, the stomata close to conserve moisture.
Answer:
A mutation is a change of the structure or gene. So, if an animal’s habitat is hanged due to like weather, and there’s an offspring who has a mutation, the mutation could actually be an adaptation due to the change in habitat.
