Answer:
polar bears begin to eat goose
Explanation:
Answer:
D. habitat preference
Explanation:
Habitat preference is one of the driving forces for ecological speciation that does not allow interbreeding between the members of a species. In habitat preference, some members of a species have a different preference for habitat than the others. They live in different habitats and do not interbreed. Over generations, these two populations of a species living in different habitats develop genetic variations and interbreed with the members of their own populations only. Gradually, these two populations would develop reproductive isolation and would evolve as two different species.
Solution a is the most acidic.
In a pH scale of 1 to 14, the smaller the pH is, the more acidic is. In opposite, the higher the pH is, the more alkaline it is. We call substances with pH below 7 as acid, and above 7 as alkali, while 7 as neutral.
Therefore, comparing the 4 solutions, solution a has the lowest pH, 3, so it is the most acidic.
Answer:
The First and Third one for sure
Explanation:
Carnivores eat primary consumers as well as other carnivores if I'm not wrong, which would make them secondary or higher consumers.
Also, herbivores eat producers, which are plants and stuff and basically organisms that make their own food, which would make them primary consumers.
Answer:
In the F1 generation
RR = 0%
Rr = 50% (or 0.5)
rr = 50% (or 0.5)
Explanation:
A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.
A white flowering plant has the genotype rr. It is homozyogous for the white allele
A punnet square of the cross is shown.
The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross
