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.
Answer:
Plants occur in dump and shaded areas
They lack vegetative structure
The plant body is prostrate or erect
They lack vascular system
This seems to be a question located online and it quite similar. It comes with a table, from there, you will only have to multiply two values depending on what is given. As for me, 148 is the answer.
The answer is most likely testing. scientists test their data againt their hyputhesis.
