Review and Reinforce Body Organization
Understanding Main Ideas
The illustration below shows the levels of organization in a reptile. The levels are
numbered 1-4, with 4 being the highest level and 1 being the lowest level. Match the
items below the illustration with the number that represents the lowest appropriate
level of organization in the illustration.
1. tissue
3 _
2. an object consisting of several different tissues L
3. the smallest unit of the body
4. group of organs that operate as a system

b) mutualism

hope this : )

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
