Organisms overproduce offspring, so only some survive and pass on their traits.
Natural selection is the fitting of a population to its environment.
Explanation:
Most organisms produce more than two or more offspring in their lifetime. Therefore the subsequent generations ideally have more individuals than the previous. However, naturally, the population size does not grow indefinitely. This is because some individuals do not survive to pass their genes to the next generation. Natural selection chooses the best fit individuals to habitat, and these live long enough to pass their traits to the next generation. Natural selection powers the evolution of a population even as environment changes

These are the common main factors negatively affecting species around the world:
• Invasive species. The overview of non-native species into an ecosystem can intimidate endemic wildlife, distress human health and upset economies. Scientist solution contain making systems to avoid introduction of invasive species in the first place effectively monitoring for new infestations and fast abolition anew noticed intruders.
• Over-exploitation. Overhunting, overfishing and overharvesting give importantly to the damage of biodiversity which is killing of numerous species over the past several hundred years. The solution is conservation and constant consciousness neighboring over-exploitation mostly poaching and overfishing.
• Climate change. Alterations in climate over our planet past have altered life on earth in the long run which ecosystems have originate and left and species regularly go nonexistent. The solution must be reducing carbon prints and promoting education.
• Deforestation and habitat loss. This is a direct cause of extinction and loss of biodiversity. The solution is recommending stronger scientific forest protection laws.
• Lastly is the pollution. Acid rain which is normally initiated by the burning of fossil fuels can acidify smaller bodies of water and soil harmfully affecting the species that live there by altering breeding and nourishing habits. The solution must combat atmospheric and hydrologic pollution.
<span>Rills, gullies, streams, rivers and tributaries are all caused by water erosion. Water erosion is the natural act by which water flow (or wind flow) slowly removes soil, rock, or any material found in the earth's crust. The removed materials are transported to another location, leaving behind changes in the crust.</span>
Answer:
Maximum height is20m and time taken will be 2second
Explanation:
vi=20m/s
vf=0m/s
g=10m/s^2
Using third equation for objects falling freely
2gh=(vf)^2-(vi)^2
Putting values
2(10m/s^2)h=(0m/s)^2-(20m/s)^2
20h=400m
h=20m
Now we have to find the time
Using first equation of motion for objects falling down freely
vf=vi+at
substituting the equation
(vf-vi)/g=t
(0-20)/10=t
t=2second
F = focal lenght = 67.1 cm
u= distance between mirror and object = 16.76 cm
1/f = 1/v + 1/u
1/67.1 = -1/16.76 + 1/u
1/67.1 + 1/16.76 = 1/u
u = 13.41
