Answer:
This is because animals do not need to store as much water as plants.
Explanation:
Animals generally have smaller vacuoles than plants. Plants have large vacuoles that can occupy a large portion of their cell (up to 30 percent). The major function of the vacuole is to store water and maintain cell turgidity and pressure against the cell wall.
Animals on the other hand do not have a rigid cell wall, rather, they have a flexible cell membrane. As a result of this, they do not need to store water in vacuoles.
weight = mg
W on earth = 800N
mg = 800 N
m(9.8 m/s²)= 800N
dividing 9.8 both sides
m=800/9.8 ( as g=9.8m/s² on earth)
m=81.63 kg
Now weight on Mars
w=mg
=(81.63kg) ×(3.76m/s²)
w=306N
Answer:
Properties of semiconductors are determined by the energy gap between valence and conduction bands. To understand, what is semiconductor, we have to define these terms. In solid-state physics, the energy gap or the band gap is an energy range between valence band and conduction band where electron states are forbidden.
The answer is disturbance; energy.
Waves deliver a method of transporting energy without
transporting matter. Undertaking of the particles are similar to the motion of
the energy. Sound waves touching over the air is an instance
of this kind of wave.
