Overproduction
Most species produce more offspring than can survive.
Competition
Since living space and food are limited, organisms must compete for the necessities.
Variation
Differences between individuals in a population.
Adaptations
Any kind of inherited trait that improves an organism's chances of survival.
Natural selection
The environment selects organisms with optimal traits to be the parents of the next generation.
Speciation
Over many generations, favorable adaptations accumulate and may result in a new species.
Answer:
hehe, thanks bro. Brainliest maybe...?
A and D would make the most ground disruption but i think it is B in situ leaching
Not really, no. Usually acquired immunity is actually brought on by breast milk.
Answer:
Bb and Bb
Explanation:
Let B be the allele of a black color; &
Let b be the allele of a white color
Allele B is dominant over allele b, and as such it masks the expression of allele b
If we have a cross between two heterozygous individuals
i.e Bb × Bb
we have:
B b
B BB Bb
b Bb bb
From above, Phenotypically;
we have the following offspring:
BB ; one normal black color
2 Bb: two heterozygous for black color
bb : one white color
The color ratio is in the ratio of 3 black :1 white which is synonymous to 10 black : 3 white
So; we can therefore conclude that the genotype of the parents are :
Bb and Bb
