Possession of flagellum is not a taxonomic feature. many different unrelated organisms have flagellum. euglena, zooflagellates but also some fungi or even human sperm cells.

Answer:
The body of a fish is streamlined because, it increase the speed of the fish in the water. The more the streamlined shapes more easier for the fish to swim in the water.
Answer:
7.5cm
Explanation:
Velocity vs Time Graph:
When the object is going along the plane with velocity v at a particular time interval t we can explain it's motion via the velocity vs time graph. If the velocity of the object is constant then velocity vs time graph will produce a horizontal straight line. If the amount of differentiation of velocity of the object is positive and constant then the graph shows the linear line whose slope is is the same as the ratio of the change in velocity to the time interval.
Velocity vs time graph:
Is shown in the attached image
A velocity-time graph helps us to estimate the distance traveled by using the area under the graph.
Height of the triangle is the velocity (v) = 0.75m/s
The base of the triangle is the time interval (t) = 0.2sec
Distance travelled = Area of triangle
Distance travelled
= 1/2(V) * t
= 1/2(0.75m/s) * 0.2s
= 0.0075m
=7.5cm
Thus, during one beat blood flows 7.5 cm
Though it is not yet widely practiced, phages (aka bacteriophages) are one way to overcome the obstacle of antibiotic-resistant bacteria. Phages specifically kill bacteria as they fulfill their own duties in their life cycle.
Kites most likely spent the majority of the time active perching because they were actively looking for prey from an arial angle which allowed them to scope out their next victim
