Answer: The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.
 
        
                    
             
        
        
        
Answer:
Human evolution in the hominid family occurred faster than between Chimpanzees and gorillas. Neutral mutations may result in sequence divergence between organisms that are structurally similar (in this case, chimpanzees and gorillas)
Explanation:
Human and chimpanzee share higher sequence identity than predicted in the hominid family since observed mutations are necessarily associated with functional divergence
 
        
                    
             
        
        
        
Two-point discrimination is the minimal distance which someone can perceive two different stimuli that given simultaneously. An area with higher receptor density will have a lower two-point discrimination result since the distance between receptor is lower. 
The area that needs a high sensitivity like the palm of the <span>hands(especially the fingertips), face</span>, and tongue should be the one with lowest two-point discrimination. 
In this report, a<span>nterior forearm two-point discrimination result is the lower than the fingertip. This result is suspicious since the forearm shouldn't more sensitive than the fingertip. Fingertip two-point discrimination is around 2-6mm and forearm should be much higher than 6mm.

Answer:182.25 joules 
Explanation:
Mass=0.18kg
Velocity=45m/s
Kinetic energy=(mass x(velocity)^2)➗2
Kinetic energy=(0.18 x 45^2) ➗ 2
Kinetic energy=(0.18x45x45) ➗ 2
Kinetic energy=364.5 ➗ 2
Kinetic energy=182.25
Kinetic energy=182.25 joules
