SC.8.E.5.7
Which planets are rocky?
Mercury, Venus, earth, mars.
What is the primary source of energy for photosynthesis?
Sunlight
What is the basic unit of structure and function in all living things?
Cell
What is the basic building block of all living things?
Cells
A tapeworm lives inside the intestines of a dog, taking nutrients from the dog's food. The dog becomes sick and loses weight. What type of relationship is this?
Parasitism
Why is a year in mars longer than earth?
It is farther from the sun.
In which cell organelle does photosynthesis occur?
Chloroplast
What is an example of an organ?
Heart
Which part of the cell theory explains that new cells are produced from existing cells?
Cells come from pre existing cells
A clownfish lives in the stinging tentacles of a sea anemone. The clownfish gets protection, and the sea anemone is cleaned by the fish. What type of relationship is this?
Mutualism
What happens to a comets speed near the sun?
It increases due to gravity.
Which gas do plants take in from the atmosphere to perform photosynthesis?
Carbon dioxide
A group of similar cells working together to perform a specific task is called a:
Tissue
What instrument was essential for scientists to develop the cell theory?
Microscope
Several species of warbler birds eat insects on the same pine tree, but they feed on different parts of the tree (some top, some bottom). This allows them to coexist. This is an example of reduced what?
Competition
This feature of the sun appears darker because it is slightly Cooler than the surrounding gases.
What are sunspots?
What best describes how energy is transformed during photosynthesis?
Solar energy is transformed into chemical energy
in what list shows the levels of organization from smallest to largest?
Cell - tissue - organ - organ system - organism
What is not part of the cell theory?
cells arise from non living matter
A cattle egret follows cattle around in a field. As the cattle graze, they stir up insects, which the egrets then eat. The cattle are not affected by the birds. This is an example of:
Commensalism
why is Venus hotter than mercury?
It’s dense atmosphere traps heat.
What are the primary products of photosynthesis?
Glucose & oxygen
What is an example of an tissue?
Nerve cells acting together
If a scientist looks through a microscope and sees a microorganism reproducing, which part of the cell theory does this support?
All cells come from existing cells
In a specific forest ecosystem, foxes prey on rabbits. If a disease drastically reduces the rabbit population, which of the following is the most likely immediate result on the relationship between foxes and other predators (like hawks) in that ecosystem?
Competition increases between foxes and hawks.
