Answer:
The correct answer is 3. peritrichous
Explanation:
Flagella is the surface structure found in bacteria that helps in the locomotion of the bacteria. There can be single flagella that can be located at one end of the bacteria or many flagella present on all over the cell surface of the bacteria.
If a bacteria contains only one flagella at one end it is called monotonous. If many flagella are present at one end then it is called lophotrichous. When both the end of bacterial cell contains an equal amount of flagella then the bacteria is amphitrichous.
Peritrichous are those bacteria which contains many flagella that are located all over the surface of their body, for example, E. coli is the bacteria present in human intestine having flagella distributed all over its surface.
Answer:
The correct answer is - B. disruptive selection.
Explanation:
Adaptive radiation is a type of genetic drift that relatively fast evolution of many species from a single common ancestor which means there is a big drift in a very small time.
Disruptive selection is a type of natural selection that shows phenotypes (individuals with groups of traits) of both extremes but has very few individuals in the middle. An example of this type is the evolution of mammals after the extinction of dinnosaurs.
Answer:
All cells have a nucleus, which acts like the brain of the cell
Explanation:
prokaryotic cells don't have a nucleus
