Answer: Option 1 is correct.
Explanation: Population produces offspring because as long as there are two types of organisms in the population, male carrying XY chromosome, and female carrying XX chromosome mating will occurs and once mating starts to occur
offsprings will be given birth to, this is why population has offsprings of the parents.
Most organisms lives to maturity and give rise to another offsprings which makes up the next generation.
All population grow over time, as long as there is mating, there will be offsprings and as long as the number of organisms in a population increase there is growth in the population.
Option 2 is incorrect because as population grows, resources reduces and becomes scarce because of the total number of organisms competing for the available resources.
Not on the oustide/coast. Inside a country.
Not sure what the options are, but artificial selection would be when farmers/breeders choose only to plant/breed the organism with desired characteristics in order to cause the evolution of the trait while natural selection is when organisms that are better adapted to their environment usually survive and produce offspring, causing the evolution of their traits which help them to survive.
Hope that helps!
The number of chromosomes in sex cells is half that in somatic cells.
Assuming that the disease decreases the affected component:
Osteocytes: These help in bone production so if they decrease, bone density will decrease.
Osteoclasts: These break bone down so if they decrease, bone density increases
Osteoblasts: Help in bone production, their decrease will reduce bone density.
Collagen fibers: Help in bone production, their decrease will reduce bone density.
