Biology — The Design of Life: Unit Quiz
Question 1 of 10
What is the fundamental unit of all living organisms?
The atom
The cell
The organ
The molecule
Question 2 of 10
What does 'irreducible complexity' mean in the context of cell biology?
A system that is too complex for scientists to understand
A system that requires all its parts to be present simultaneously to function
A system that becomes more complex over time through mutation
A system that can be reduced to simpler components and still work
Question 3 of 10
What is the role of ATP in the cell?
It stores genetic information
It serves as the cell's primary energy currency
It forms the structural framework of the cell membrane
It carries oxygen through the bloodstream
Question 4 of 10
According to Mendel's Law of Segregation, what happens to alleles during gamete formation?
Both alleles are passed to every gamete
Alleles blend together to form a new allele
The two alleles for each trait separate so each gamete carries only one
Alleles are randomly mutated before being passed on
Question 5 of 10
What are the four nitrogenous bases found in DNA?
Alanine, Thymine, Cysteine, Glycine
Adenine, Thymine, Cytosine, Guanine
Adenine, Uracil, Cytosine, Guanine
Arginine, Tryptophan, Cysteine, Glutamine
Question 6 of 10
What is the correct sequence of information flow in the Central Dogma of molecular biology?
Protein → RNA → DNA
RNA → DNA → Protein
DNA → RNA → Protein
DNA → Protein → RNA
Question 7 of 10
Which body system is responsible for maintaining homeostasis through hormonal regulation?
The skeletal system
The integumentary system
The endocrine system
The lymphatic system
Question 8 of 10

1%
10%
50%
90%
Question 9 of 10
According to Genesis 1:24, God created living creatures 'according to their kinds.' How does modern genetics support this concept?
DNA evidence shows all organisms evolved from a single ancestor
Genetic variation occurs within kinds, but organisms reproduce after their own kind
Mutations regularly produce new kinds of organisms
Genetics has disproven the concept of created kinds
Question 10 of 10
What is Biblical stewardship of creation, as described in Genesis 1:28 and 2:15?
Humans should avoid using any natural resources
Humans should exploit the earth for maximum profit
Humans should exercise responsible dominion over creation as God's stewards
