Answer:
D
Explanation:
D is an example of confirmation bias because confirmation bias involves people looking for information to support their opinions and beliefs, the person confirms their already existing biases and beliefs when they seek out information to support these biases and beliefs whilst ignoring contradicting information. The journalist is confirming his belief that climate is not real when he cites an article discussing how humans cannot be causing climate change and when he ignores several other articles that discuss how humans can cause climate change so as a result he is confirming his own bias and belief.
The correct answer is (b) Increase
Pines trees are infected by different insects during the adverse and stressed environmental condition. Pine borer beetle is pest that infect pine tree during the stressed condition due to lack of water in that area. In healthy condition pines can kill these insects but in stressed condition insect will effect the plant so if the number of beetle will decrease, the population of pines will increase in that area.
Answer:
Frequency of B allele is 0.6681
Explanation:
If p represents the frequency of dominant allele and q represents the frequency of recessive allele, according to Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where p² = frequency of homozygous dominant genotype
q² = frequency of homozygous recessive genotype
2pq = frequency of heterozygous genotype
Given that number of recessive chestnut horse = 28
Total horses = 226 + 28 = 254
frequency of b² genotype = 28/254 = 0.1102
frequency of recessive b allele = √0.1102 = 0.3319
So, frequency of B allele =
1 - 0.3319 = 0.6681
Hence frequency of B allele is 0.6681
Answer:
C. nudation
Explanation:
When an ecological system has been destroyed by some catastrophe, what is left is usually barren land. This barren land is not suitable for the majority of the organisms to live on it, so changes are needed. Nudation is the first process, and it is part of the primary succession. This process is actually the one responsible for the minor changes that happen on the barren land, preparing it slowly for the organisms to be able to move into it and start developing a new ecosystem.
