List features that distinguish living organisms from nonliving matter. - 🧠
ANSWER ✔✔1. Cellular basis - All living things consist of one or more cells
2. Requirement for energy and nutrients - Life is sustained by ongoing
inputs of energy and nutrients
3. Homeostasis - Living things sense and respond to change
4. DNA is hereditary material - Genetic information in the form of DNA is
passed to offspring
Describe the levels of organization in the living world. - 🧠 ANSWER
✔✔Atoms → cells → tissues → organs → organ systems → organism →
population → community → ecosystem → the biosphere
,List the three domains of life and distinguish between each domain. - 🧠
ANSWER ✔✔Prokaryotes are bacteria and archaea.
Domain Bacteria: unicellular no nucleus
Domain Archaea: unicellular no nucleus but closer to eukarya
Domain Eukarya: have nucleus
List four kingdoms within the domain Eukarya and distinguish between
them. - 🧠 ANSWER ✔✔1. Fungi can be single or multicellular but digest
food outside their body.
2. Plants are multicellular and are photosynthetic.
3. Animals are multicellular and eat other organisms for nutrients.
4. Protists are the unicellular organisms that have a nucleus but do not fit
any other category.
List and describe the steps involved in solving a problem using hypothesis-
based science - 🧠 ANSWER ✔✔observation
hypothesis
experimental
conclusion
, Describe the concept "an organism is more than the sum of its parts." - 🧠
ANSWER ✔✔organism is part of a more complex organization. These
emergent properties go beyond itself.
By definition, distinguish between a population, a community, and an
ecosystem. - 🧠 ANSWER ✔✔1. Population: multiple organisms in a single
spot
2. community: is made up of populations of different organisms
3. ecosystem: is the interactions between the community and the non-living
environment that surrounds it
Distinguish between a producer, a consumer and a decomposer. - 🧠
ANSWER ✔✔producer:photosynthetic organisms that trap light and convert
that light energy into chemical bond energy. such as some bacteria,
protists, and all plants
consumer: organisms that feed on already-stored food
decomposer: bacteria and fungi recycle the dead molecules throughout the
bioshpere.
Distinguish between a hypothesis and a prediction. - 🧠 ANSWER
✔✔hypothesis: testable explanation of a natural phenomenon.
