Answer:
eukaryotic cells
Explanation:
Eukaryotes are organisms whose cells have a nucleus enclosed within membranes. Prokaryotic cells do not have a nucleus
Answer:
31. Seatbelts lock in place to make sure you don't go flying into the windshield.
32. Friction causes the soccer ball to slow down. If we were to kick a soccer ball in space, where there is no friction, it would keep on rolling until it eventually hits something or goes out of sight.
33. Heavier loads will make the vehicle move off of the table. The heavier the weight, the quicker the vehicle will roll. Loads that are something very similar or lighter than the vehicle won't make the vehicle move by any means.
34. Gravity is the power pulling the piano toward the Earth.
Friction would happen with an unpleasant surface, making it a lot harder to push the piano up the ramp.
35. Wagon C
Wagon C has the least boxes and minimal measure of mass, making it simplest to move.
36. I would move the crates so every cart has a similar measure of boxes, making them equivalent in mass. This would make them all take a similar measure of power to move them.
Explanation: I have the answer key
I learned that it was Ask A Question but out of those I would say Research The Problem.
1) Carbon dioxide
The carbon atoms present in CO2 are used by the plant in the formation of the organic molecular group (sugar).
2) Chlorophyll
Photosynthetic pigments present in chloroplasts, responsible for absorbing light from wavelengths between blue and yellow and reflecting different shades of green
3) Oxygen
Oxygen is the end product of photosynthesis, the result of the breakdown process of water molecules.
4) Stomata
Stomates have the function of performing gas exchange between the plant and the external environment. This structure is also responsible for the perspiration of the plant.
5) Sunlight
Energy source for the process of transforming light energy into chemical energy
6) Glucose
Final product of photosynthesis. Molecule that will be used by the plant to maintain its vital functions.
7) Water
Oxygen source that will be released as a gas at the end of the process.
Answer:
Independent variable: Type of battery
Dependent variable: Time the clock stopped
Control: None for this experiment
Constants: Same type of clock
Explanation:
Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.
Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY
Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.
Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.
