Answer:
1.A tissue is a collection of similar cells that work together to perform a specific job.
An organ is a collection of different tissues that work together to perform a specific job. The function of a part of an organism is what it actually does (it's job)
2.The structure of the alveoli as a web of blood vessels surrounding an air sac allows blood cells take in oxygen and bring it into the lungs (organ)
Transpiration: process in which plants release water vapor into the air
Evaporation: process in which water changes to a vapor
Precipitation: water that falls from clouds toward the ground
Condensation: water vapor that cools down to form water droplets
Groundwater: flowing of rainwater downhill to form streams and rivers
No somethings only have one cell. they are called unicellular organisms.
Answer:
light
Explanation:
The above experiment is an investigation on the factors that affect photosynthesis which include carbon dioxide concentration,light intensity and quality,chlorophyll, water and temperature.Light was the independent variable. When the lant is moved to an area where light intensity is low, the rate of photosynthesis decreases.
After the experiment, oxygen gas is produced being a by-product of photosynthesis. Plants that are not adapted to an aquatic environment are not suitable for this experiment. The amount of carbon dioxide dissolved in water is low.
