What are the characteristics of living things?
made up of cells
do not reproduce
contain DNA
growth and developement
obtain and use materials; use energy
dont respond to their environment
do not maintain homeostasis
as a group, living things evolve
What is a life function?
a process that an organism carries out to survive
processes that an organism carries out in order to survive
the processes that dont help an organism survive
The process by which living things ❌ and ❌ materials from its environment for growth and repair is called ❌.
What happens to materials that cannot be digested by organisms?
the organism throws up
the materials remain inside
the materials are egested
What is autotrophic nutrition?
a living thing creates its own food
a living thing competes for its own food
a living thing hunts for its own food
a living thing does not ingest food
How do heterotrophic living things eat?
by obtaining energy from the sun
creating its own food
eats nothing
ingests its own food
Transport is the process by which substances enter (absorption) and leave the cells and become more distributed (circulated) within the cells.
Respiration turns nutrients to energy.
The process of releasing chemical energy stored in nutrients is called
metabolism
synthesis
dehydration
respiration
Respiration does not convert the chemical energy into a usable form called ATP.
What is aerobic respiration?
does not require oxygen for chemical reactions during the function of respiration to occur
requires oxygen for chemical reactions during the function of respiration to occur
What is anaerobic respiration?
The removal of wastes that are not produced by many chemical reactions occurring in the body is called excretion.
Reproduction is the process by which living things produce new organisms of their kind.
Its mandatory for an organism to reproduce otherwise it will die.
What is sexual reproduction?
two parents involved and the offspring are not identical
a single individual produces offspring that are identical to that parent
What is asexual reproduction?
two parents are involved and the offspring are not identical
Growth is the process by which organisms increase in size.
In unicellular organisms, the size of the cell ❌. In ❌ organisms, the size and the number of ❌ increase.
Development is the changes an organism goes through in their life time.
__________________ is the process of combining simple substances to make more complex substances that the organism needs.
regulation
What includes all of the activities that help to maintain an organisms stability?
reproduction
Homeostasis is when an organisms internal environment remains constant.
What are stimuli?
noises in the environment
effects of a cause
changes in environment
Which two systems carry out regulation in complex animals?
skeletal
ciculatory
nervous
endocrine
none of the above
Metabolism refers to all chemical reactions occurring within the cells of an organism.
