Answer:
All parts of the food chain are very important for if one is part of the food chain is tooken away than other parts of the food chain will be affected.
Explanation:
- A chemical reaction is considered as a process of transformation of chemical reactants into products.
- Chemical reactions involve change in position of electrons or breaking the bonds between atoms to form new molecules. (no change in the elements present).
- Chemical reactions are best described by chemical equations
So the correct answer is B
Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right
In first place, acceleration in a body occurs when a force acts on a body.
Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object
Mathematically, Newton's second law is expressed as:
F= m×a
where:
- F = Force [N]
- m = Mass [kg]
- a = Acceleration [m/s²]
In this case, you know:
- F= ?
- m= 2.2 kg
- a= 4.4 m/s²
Replacing in Newton's second law:
F= 2.2 kg× 4.4 m/s²
Solving:
<u><em>F= 9.68 N</em></u>
Finally, As the bowl of fruit accelerates to the right, the correct answer is option A. F = 9.68 N right

The correct answer is B. a fossilized fish
That is because the scientist can use carbon dating to find the age of the fish, and that will tell the scientest the date of the layer of rock. :)
