Vanessa made a list comparing the differences between the outer coverings in plants and animals, but she made a mistake. Read th

e table and then choose the statement that explains why the list is incorrect. Structure Description of Function Spines Protects the plant from predators and helps increase water loss Skin Protects the animal from changes in weather and its environment The skin is a reproductive organ. The skin offers little protection against the weather. The spines attract predators. The spines help decrease water loss.

The skin is NOT a reproductive organ and the spines attract predators are the incorrect statements.

<h3>Why the list is incorrect?</h3>

The list is incorrect because skin is not a reproductive organ and the spines do not attract predators towards each other. Skin protects the body from the outer environment whereas the spines repel the predators from the plant body.

So we can conclude that the skin is NOT a reproductive organ and the spines attract predators are the incorrect statements.

To solve this problem it is necessary to apply the conservation equations of the moment for an inelastic impact or collision. In turn, it is necessary to apply the equations related to the conservation of potential energy and kinetic energy.

Mathematically this definition can be expressed as

m_1v_1+m_2v_2=(m_1+m_2)v_f

Where,

v_{1,2} = Initial velocity of each object

m_{1,2} =Mass of each object

v_f =Final velocity

Our values are given as

m_1 = 0.25kg\\m_2 = 0.5kg\\v_1 = 1.2m/s\\v_2 = 0m/s

Replacing we can find the value of the final velocity, that is

0.750v_f = 0.25*1.20+0.5*0

v_f = 0.4m/s

From the definition of the equations of simple harmonic motion the potential energy of compression and equilibrium must be subject to

KE_{compressed}+PE_{compressed} =KE_{equilibrium} +PE_{equilibrium}

Since there is no kinetic energy due to the zero speed in compression, nor potential energy at the time of equilibrium at the end, we will have to

0+\frac{1}{2}KA^2 = \frac{1}{2}(m_1+m_2)v_f^2+0

Re-arrange to find A

A = \sqrt{\frac{m_1+m_2}{k}v_f}

A = \sqrt{\frac{0.25+0.5}{10}(0.4)}

A = 0.11m

Finally, the period can be calculated through the relationship between the spring constant and the total mass, that is,

T = 2\pi \sqrt{\frac{m_1+m_2}{k}}

T = 2\pi \sqrt{\frac{0.5+0.25}{10}}

T = 1.7s
