Answer:
1) in the direction of the applied force
2)when the movement is not in the direction of the applied force it is not work. But if a component, or part of the motion is in the direction of the applied force it is work.
3)Joules/sec
4)Force/displacement
6)Wedges and lever
5)conduction
6)radiation
7)there is no heat flow
8)The average kinetic motion of the particles increases, there is more thermal energy
9)The average kinetic motion of the particles decreases, there is less thermal energy
10)transverse wave
11) sound waves
12)they transfer energy through oscillations in matter
13)the speed of the pitched baseball
14)to detect speed and direction of blood flow
15)green and violet are reflected and red is absorbed
16)visible light
17)as heat
18)infrared light/infrared energy
19)reflection
20) yes, the forces emitted by having the same charge repells them.
21)the flow of electrons
22)You open the circuit and the electrons can't flow
23)You closed the circuit and the electrons can flow
24)I think you meant bipolar, this means 2 poles
It’s active transport because it requires energy
Answer:
Rural population.
Explanation:
The rural population of humans is characterized by the lag phase because they are linked with farming of crops and domesticated animals. This population is responsible for the soil erosion and food shortages over the country because they are the producers of everything for the food industry. Due to farming methods, soil erosion occurs that leads to the depletion of nutritive part of the soil that causes less productivity of the crop and as a result food shortage occur.

<span>Natural
selection has 4 processes.</span>
<span>Individuals looks different and have different
characteristics from another within their own species (genetic variation). Some
characteristics suits better for the environment, which has to be passed on
from one generation to the next. The humming birds with long bills will mate
with those that have that too so they'll produce offspring with long bills. </span>
<span>The
second process is over production of offspring. The humming birds produces lots
of offspring but only a few survives. </span>
<span>Another factor of natural selection is
struggle for existence, which leads to differential survival and reproduction.
There are environmental pressures, like not having enough space or food, for
example, humming birds compete fiercely for resources like nectar. Natural
selection will favor individuals that are more efficient at getting nectar and
natural selection will result in changes in wing shape which can allow them to
fly longer distance and affect the length and shape of bill for them to drink
nectar. Little changes may affect how well they feed and survive. Those who are
the fittest survives and are most likely to reproduce and pass on their
advantageous genes to their offspring. If the long bills are more advantageous
and can survive better in a particular environment, then overtime, those with
short bills will disappear because they can't survive and the entire population
would have long bills.</span>
