Answer:
b. the rotary flagella to change their rotation to allow the bacterium to change direction randomly
Explanation:
The bacterial flagella are made up of flagellin protein. The bacterial flagella is divided into three parts hook, filaments, and the basal body. Rotor is present in bacterial flagella which extends to the cytoplasm and makes C ring.
C ring contains several switch proteins that change the rotation of the flagella instantly in response to repellent or attractant which allows to change the direction of bacteria randomly. Bacterial Flagella can move clockwise and counterclockwise. Therefore the right answer is B.
The experimental conditions are always kept the same.
The results of the experiment are always accurate.
The same results are expected each time the experiment is done.
Answer;
The same results are expected each time the experiment is done.
If an experiment exhibits reproducibility it means the same results are expected each time the experiment is done.
Explanation;
Reproducibility is the ability of other people to produce the same results from a given experiment under the same conditions, and without the influence of unanticipated factors.
Reproducibility is an important aspect of science, this is because it ensures transparency and gives us confidence in understanding exactly what is done.
B) moving.
C) made of cells.
D) round throughout.
The correct answer is (c) made of cells.
Cell is the basic structural and functional unit of life. The study of cell is called cell biology. Cells can easily be observed under a microscope. As pond water contains many microscopic structures such as bacteria, protozoa, algae and some small insects they can easily be observed under microscope. The organism that is seen can be unicellular or multicellular
the answer is made of cells
