In single celled organism materials are stored primarily in
ribosome
mitochondria
nuclei
vacuoles
The diagram below represent levels of organization in living things
which term would best represent X?
human
stomach
tissue
organelle
There are 2000 kinds of edible insects in the world, and they are becoming an increasingly popular source of protein. One cup of cricket flour contains 28 grams of protein. The building block in cricket flour are
amino acid
water
simple sugars
carbohydrates
The organic compounds that scientist use to cut, copy, and move segments of DNA
carbohydrate
enzymes
harmones
starches
In which cell structure is energy extracted from nutrients?
chloroplast
ribosome
mitochondria
vacuole
single celled organisms are able to maintain homeostasis, even though they lack higher levels of organization such as organs and organ systems, because
single-celled organisms do not carry out the same life processes as multicellular organisms
multicellular organisms do not rely on tissues or organs to carry out life processes
cell structures work together to maintain homeostasis in single-celled organisms
single-celled organisms are able to coordinate organ functions to maintain homeostasis
which cell structure plays a direct role in the release of this chemical from the cell?
nucleus
ribosome
chloroplast
cell membrane
A student observed five living cells in the field of view of a microscope as represented below.
What is the approximate diameter of one cell?
10 μm
50 μm
250 μm
500 μm
Which sequence best represents the levels of organization in a paramecium, a single-celled organisms?
The diagram below represents two processes that occur in some living organisms.
the letter X represent
the nucleus
mitochondrion
sunlight
carbohydrate
The diagram shows specialized plant cells that control openings called stoma
The proper function of these cells are vital to the survival of these plants because the regulate the
rate of glucose used by root cells
absorption of sunlight by leaf cells
products of photosynthesis in the cell
exchange of gases in the leaves
headline such as these best illustrate the concept that
scientific explanations are tentative and subject to change
some newspapers are not honest and report incorrect information on purpose
worms can enter the body many different ways
worms found in swamp should not be used for fishing
Two biological process that occur in certain organelles are represented in the diagram
which statement is correct regarding the types of organisms able to carry out of the processes?
Process X occurs in heterotrophs, but not autotrophs.
Process Y occurs in consumers, but not in producers.
Process X and Y occur in all living things.
Process X and Y occur in green plants.
Which cell structure is represented by B?
vacuole
ribosome
cytoplasm
chloroplast
The nucleus contains molecules of A, which
recycle waste products
remove water from the cell
store hereditary information
regulate the pH of cytoplasm
