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
Hello!
The type of selection which is illustrated by these two graphs is a
Stabilizing Selection
Among the different types of Natural Selection.
Stabilizing Selection is the one that happened to the parrot population in the rainforest in Costa Rica. This is characterized by the selection against the extremes of an attribute and reinforcement of the mean, that's why this type of selection is also called Selection towards the mean.
In this case, there was selection against the parrots with colored feathers other than green that didn't help them to camouflage in the rainforest.
Have a nice day!
Answer:
Unicellular - Archaea and Bacteria
Multicellular - Eukarya
Explanation:
Domain is the highest taxonomic rank in the hierarchical biological classification system, above the kingdom level. There are three domains of life, the Archaea, the Bacteria, and the Eukarya.
Answer:
The statement is true.
Explanation:
The soluble nutrients from digestion (amino acids, sugars and soluble vitamins) travel from the intestine to the liver through the portal vein. The transport of lipids, cholesterol and fat-soluble vitamins is much more complex, since they are not soluble, they cannot be sent to the portal vein because there they would quickly produce fat deposits, and must be sent through the lymphatic system. Among the functions of the lymphatic system, two should be highlighted: its central role in the immune system, and its role in the transport of lipids and cholesterol from the diet. Lymphatic ducts from the intestine converge into the thoracic duct that joins the bloodstream near the entrance to the superior vena cava, where the lymph content passes into the systemic blood circulation.
Amphibians are more adapted towards moist environments
