Biology Midterm Exam comprehensive
Questions and Answers with Verified
Solutions
Question 1:
Biology
Answer:
Scientific study of life
Question 2:
Organism
Answer:
a unit of life (multi-cellular or uni-cellular)
Question 3:
Growth & development
Answer:
During fertilization, a single fertilized egg divides again and again. As the
cells divide, they differentiate, which means they begin to look different
from one another and to perform different functions.
,Question 4:
Reproduction
Answer:
All organisms produce new similar organisms. Most plants and animals
engage in sexual reproduction. In sexual reproduction, cells from 2
parents unite to form the 1st cell of a new organism. Other organisms
reproduce through asexual reproduction, in which a single organism
produces offspring identical to itself.
Question 5:
Species
Answer:
a group of similar organisms that can breed and produce fertile offspring.
Question 6:
Stimulus response
Answer:
Organisms detect and respond to stimuli from their environment. A
stimulus is a signal to which an organism responds.
Question 7:
Homeostasis
Answer:
All organisms need to keep their internal environment relatively stable,
even when external conditions change dramatically.
, Question 8:
Adaptation
Answer:
heritable characteristic that increases an organism's ability to survive and
reproduce in an environment.
Question 9:
8 characteristics of life
Answer:
• Made up of cells • Based on a universal genetic code • Obtain and use
materials and energy • Grow and develop • Reproduce • Respond to
environment • Maintain a stable internal environment • Change over time
Question 10:
science
Answer:
Organized way of gathering and analyzing evidence about the natural
world.
Question 11:
Theory
Answer:
well-tested explanation that unifies a broad range of observations and
hypotheses, and enables scientists to make accurate predictions about
new situations.
