Deep sea bacteria live at ocean depths too great for light to reach. These bacteria make their own food using inorganic compounds through this process.
What is chemosynthesis

Corals are marine animals that often live in tropical seas. Many types of corals have unicellular algae living in their tissues. The algae provide up to 98 percent of the corals' food. The corals provide protection and inorganic nutrients for the algae. Some coral cells undergo meiosis. One of these would not occur during meiosis: a. formation of a zygote b. chromosomes crossing-over c. production of gametes d. reduction in number of chromosomes
What is formation of a zygote

Which of these best describes the correct sequence in the expression of a trait? a. trait → gene → enzyme b. gene → protein → trait c. protein → gene → trait d. gene → trait → DNA
What is b

Transport that requires energy from the cell is considered this type of transport

Which of these statements about photosynthesis and respiration is true? A. Both processes produce food. B. Both processes release energy from food. C. Photosynthesis produces oxygen; respiration does not. D. Photosynthesis produces carbon dioxide; respiration does not.
What is C

Sea stars are genetically different from each other and from their parents. These genetic differences are the result of a. mitosis b. cloning c. sexual reproduction d. asexual reproduction
What is sexual reproduction

Which of these processes would most likely cause new color patterns on the head and neck of bog turtles? a. mitosis b. mutation c. succession d. replication
What is mutation

This type of transport requires no energy and uses a protein channel to carry substances across the cell membrane.
What is facilitated diffusion

A drawing of a mobile form of the single-celled green algae is shown. This structure helps it to move.
What is flagella

In crickets, the rate of chirping is related to the temperature of the air. The rate of chirping can be used to describe their metabolic activity. Draw a graph indicating how temperature affects metabolic activity in crickets

A student observes a unicellular organism with no nucleus under a microscope. After a while, the organism begins to split into two cells. This is the process that produces the new cells
What is binary fission.
300
Normal thymine (T) is found in the old strand. It is replaced by an abnormal molecule (T*) in the new strand. The abnormal molecule (T*) binds to guanine (G) instead of binding to adenine (A). This is an example of an adaptation protein synthesis a mutation binary fission
What is a mutation

This would happen to an animal cell with an internal salt concentration of 0.7% if it were placed in a salt solution with a concentration of 10%?
What is shrink/shrivel/get smaller

Most organisms need oxygen for their cells to function normally. In mammals, two organ systems work together to move oxygen throughout the body. This organelle uses oxygen to release energy?
What is the mitochondria

Elodea, a freshwater plant, releases gas bubbles when it is placed in direct light. In an investigation, a student placed a lamp at different distances from an aquarium containing Elodea. The student counted the number of bubbles produced by the Elodea plant. The bubbles released by Elodea contain mostly this gas
What is oxygen

A sperm cell of a moth has 112 chromosomes therefore this has to be the amount of chromosomes in the moth's wing cells.
What is 224

Horses have 64 chromosomes in each body cell. If a horse cell undergoes meiosis, it will have this amount of chromosomes in the gametes.
What is 32

Researchers have discovered a toxin that stops cells from releasing stored energy. Cells exposed to this toxin cannot carry out many of their normal processes. This type of transport across the cell membrane is least affected
What is passive transport (Osmosis, diffusion, facilitated diffusion)

Regulating body temperature or hormone levels is an example of this in multicellular organisms?
What is homeostasis

In an ocean environment, marine life is most abundant in the euphotic zone. This zone extends from the surface waters to a depth of 200 meters, the deepest depth that sunlight can reach. It is in this range that phytoplankton capture energy from the sun. Although they are microscopic organisms, phytoplankton are the foundation that supports the marine food web. Through this process phytoplankton use energy from the sun to make their food
What is photosynthesis

One of these choices is produced as a result of fertilization? A a zygote with twice the number of chromosomes as a gamete B an egg with half the number of chromosomes as a zygote C a gamete with twice the number of chromosomes as a zygote D a zygote with half the number of chromosomes as a gamete
What is A
