Answer: a) copy tissue
Explanation:
Tissue and cells in general get damaged, or just break down from wear and tear. So the cells divide to make up for this shortcoming, effectively replacing any broken parts with fresh new ones.
Answer:
666.67 kg is the mass of a car.
Explanation:
Momentum is defined as amount of motion possessed by the the moving body. It is mathematically calculated by multiplying mass into velocity by which object is moving.
Mass of the car = m =?
Velocity of the car = v = 15.0 m/s
Momentum of the car = P = 10,000.00 kgm/s
666.67 kg is the mass of a car.
Answer:
Al(OH)₃ + 3 HCl ----> AlCl₃ + <u>3 H₂O</u>
Explanation:
In a double-displacement reaction, the cation of one compound is swapped with the cation of another. The basic structure of these reactions is:
AB + CD ----> AD + CB
In this reaction, the aluminum (Al) of Al(OH₃) is replaced by the hydrogen (H) of HCl, and vice versa.
The first resulting compound is AlCl₃. The chlorine has a subscript of 3 in order to eliminate the +3 charge from the Al cation (+3 + 3(-1) = 0). The second resulting compound is HOH, most commonly written as H₂O. There needs to be a coefficient of 3 in front of H₂O to balance the equation.
The complete balanced equation is:
Al(OH)₃ + 3 HCl ----> AlCl₃ + <u>3 H₂O</u>
The change is called evolution. They change when the organism adapts to the environment and passes the genes to the offsprings.
