Answer:
so here correct option is A. 5
Explanation:
solution
as number of population groups live in a definite area is called diversity
so here in 1 there is only 2 groups of population
and in 2 there is 3 types of population groups
and in 3 there is 2 type of population groups
and in 4 there is 4 type population group
but they are not not evenly abundant and population of 1 group that is much less
so it might be a foreign population group
so here in 5 there is 4 type of population group which means it has higher diversity compare to other
so here correct option is A. 5
Answer:
zero
Explanation:
Displacement is a vector, meaning that the direction is very important. Displacement is the distance from the starting point to wherever the object is. So a car that does a 500 m lap will have covered 500 m in distance but displacement is zero because, having come back to the starting point, the distance between the starting point and where the object is, is zero.
During the exercise period (10-15min) the blood lactic acid concentration increases to about 13.2 mmol/dL (same units as on graph) as the individual is having problems keeping up their aerobic respiration. After 15min, they stop exercising and the lactic acid concentration starts to return to normal as their body is able to take in enough oxygen and catches up with the excess lactic acid, metabolizing it into CO2 and H2O. The period between 15-20 min shows the fastest reduction in concentration.
Answer:
D. Lots of vegetation
Explanation:
Urban heat islands form when cities replace natural land cover with dense concentrations of heat-absorbing pavement, buildings, and other surfaces. This has the impact of raising energy prices (for example, air conditioning), air pollution levels, and heat-related sickness and mortality.
