<h2>It contains toxins</h2><h2>It killed off bird populations.</h2><h2>It caused harm to human populations.</h2>
Explanation:
Let us understand the term DDT
DDT : Dichlorodiphenyltrichloroethane
- This is a crystalline chemical compound
- Basically used for protecting insects eating crops
- It is colorless, odorless, tasteless
- Initially used as pesticides
It killed off bird populations: Though it does not kill birds directly by consuming, it has indirectly damaged the egg by making the egg's shell too thin which gets broken easily.
It controlled diseases like malaria: Since this option talks about positive attribute of DDT, this option stands invalid. This chemical compound controls mosquitoes attacking the crop.
It caused harm to human populations: DDT causes vomiting, tremors or shakiness, and seizures
It contained toxins: It contains moderate toxins.
Salt marshes are primarily influenced by the tidal flow.

Answer:
Codominance
Explanation:
Codominance is a pattern of inheritance when none of the alleles of a gene is dominant over the other allele of the same gene. When present together in a heterozygous genotype, both the alleles are able to express themselves. In the given example, a cross between blue and yellow flowered plants obtained the progeny with blue and yellow speckled flowers. Here, the alleles of blue and yellow flower color are codominant and express themselves in the hybrid progeny.
