Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.
A species with a wide range of tolerance can dominate most habitats due to its ability to adapt.
<h3>What is a wide range of tolerance?</h3>
A wide range of tolerance is the ability for an organism to tolerate low or high levels of abiotic contamination in it's natural habitat. This means that the organisms in question show a high level of adaptability and are able to survive in hostile environments. This allows them to remain dominant in most habitats despite contamination values.
Therefore, we can confirm that a species with a wide range of tolerance can dominate most habitats due to its ability to adapt.

Answer:
Wildlife Hazard
Explanation:
Wildlife in dangerous place
The substance, DDT, damages a bird life until it was largely ban in the 1970s. DDT (<span>dichlorodiphenyltrichloroethane) is a colorless, tasteless, odorless, and crystalline organochloride known for its insecticide properties.</span>
