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:
none, worms dont have eyes
Explanation:
Answer: positive feedback loops enhance or amplify changes. this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes. this tends to hold a system to some equilibrium state making it more stable.
Explanation:
Answer:
False.
Explanation:
Blood is one of the most important connective tissue that helps in the transportation of molecules. Blood contains the red blood cells, white blood cell, platelets and plasma,
The different blood type are A, B, AB and O. The universal recipient is blood group AB and can accepts the blood of all the different blood types. They have both the antigen A and B and no antigen. Blood is not the universal recipient but the blood type AB is universal recipient.
Thus, the answer is false.
