Answer:
Independent - Water/Type of water (salt and pure)
Dependent - Height of plant
Controlled - Amount of water
Explanation:
Independent is what the experimenter manipulates (in this case being the type of water.)
Dependent is what the experimenter measures and is a result of the independent (in this case being the height of plant)
Controlled is what you are trying to keep the same (in this case the amount of water you give each plant.)
The answer is either b or c because bio means life and diversity means different and the ants stinging other insects get rid of a population and maybe another species lives off of the species that ant killed.
When the grasslands are converted into housing projects it gets rid of everything so no trees no animals and no diversity of living organisms other than humans
Answer:
Option (d).
Explanation:
Mutation may be defined as the sudden, heritable change in the nucleotide sequence of the organism. Mutation may occur due to the errors in DNA replication or may occurs due to the mutagens.
Joshua and Lederberg experiment explains that mutation is the non adaptive and random process that occur in the organism. He used the replica plating of E.coli and grows them on streptomycin drug. The bacteria was grown on the the primary plate and they are transferred to the secondary plate with streptomycin drug in the growth environment. The resistant strain of bacteria grows in the streptomycin environment.The pattern of bacteria growth on the plate explained that mutation occurs randomly and it is a non adaptive process.
Thus, the correct answer is option (d).
The cell wall is what gives plant cells their shape. The cell wall, not to be confused with the cell membrane, is a rigid structure made up of long cellulose fibers, branching hemicellulose fibers, and pectin. The fluid pressure inside the cell also contributes somewhat to their shape.
