False in order for an ecosystem to survive there has to be some sort of competition. for example, if there were no sharks to eat little fish the little fish would over populate and then the little fish would run out of food which then means that whatever the little fish ate is now extinct and so on hinting the food chain's name. If it wasn't for competition nothing would survive
Fibrin is involved in shrinking clots which is also apart of "hemostasis" and wound healing. It has the ability to protect tumors from cells immune to cancers.
A. 12.5 m/s.
The average speed is defined as the relationship between the displacement made by a body and the total time it took to perform it.
The formula that will allow you to calculate the average speed is:
v = d/t, where d is the traveled distance and t the time it took to travel the distance.
We hace to convert 4 minutes to second:
(60 s/1 min)*(4 min) = 240 s
So, the average speed is:
v = 3000 m/240 s
v = 12.5 m/s
The correct option is C.
Primary reinforcer refers to the basic needs of an animal, such as food, water, shelter, etc. Secondary reinforcer, which is also called condition reinforcer refers to the condition in which a stimulus reinforces a behavior after it had been associated with a primary reinforcer.
In the question given above, the primary reiforcer is food.

and run on the surface of water, they will use the surface tension of the water
by applying small force which is enough not to break the tension. So to achieve
the nefarious end, we need to add a substance that would break the surface tension.
These types of substances are known as Surfactants, detergents are the example
of this. Or we can achieve nefarious end by using the molecules that worked by
charged part attached to a non-charged part.</span>
