Answer:
C. The rates of birth and immigration were balanced by the rates of death and emigration
.
Explanation:
A stable population size means that, over the years, number of individuals doesn't change significantly. This condition is only possible when the birth rate and immigration rate is balanced with the death rate and emigration rate. In this scenario, population size would not change much.
On the other hand, if a birth rate and immigration rate will increase, the population size in any area would be increased. This typically happens in growing cities. By contrast, if death rate and emigration rate increases, the size of population will decrease. This happens mostly in rural areas.
Answer:
Just before the cat drops, it was stationery. Therefore it has energy of position called potential energy.As it drops, the Gravitational potential energy is converted to Kinetic Energy,The conversion mid- air is P.E to K.E to P.E to K.E to P.E to K.E, until it touches the ground. As it touches the ground all the energy is converted to P.E energy of position.
As it runs after mouse the P.E is converted back to Kinetic , energy of motion. As it feeds on the mouse , the chemical energy obtained as protein from mouse meat.This is later converted back to Mechanical energy as (kinetic and Potential energy) in the cat.
Explanation:
<span>The answer is D. The understory oak trees are lower than the general canopy of the
woodland. Therefore they are significant, especially
dead and dry oaks, in the ‘jumping’
of fire from one point to another during wildfires.
They are a major aggravator of wildfires in California
after they are attacked by Sudden Oak Death (SOD). </span>
