He can make use of an Air Quality Monitor through AirBeam. I no options to chose from so i take it that it isnt a multiple choice question. If im incorrect im sorry
4. Large, circular lily pads are able to float on the water's surface.
Answer: cohesion
Cohesion mean that water attracted to another water. This force will make the water to form a surface tension in the lake. Water lily has a wide and thin leaf which makes it giving a low force per area. If the force applied on the surface is not bigger than surface tension, the leaf will stay float above the water. Surface tension also the reason water spider could walk on water.
5. The temperature of the water is about 5°C, while the temperature of the air is about 21°C.
Answer: heat capacity
Water has high heat capacity. High heat capacity mean that the water will not be easily become cold or hot. It will need more energy to increase/decrease the temperature of the water. This is why the water could keep its temperature much lower than the atmosphere. This will protect the organism inside the water from an extreme temperature change.
In biology, evolution is the change in the inherited traits of a population from generation to generation.
Common traits that have evolved in creatures are multicellular, heterotrophic, obtaining their energy by consuming energy-releasing food substances, reproduction and changes in cell structures.
Answer:
The correct answer is : Biosphere 2 is a model based on the creation of a miniature ecosystem with life support systems.
Explanation:
Biosphere 2 is a small model of the biosphere, which is planned by scientists and engineers, that is closed and isolated from the outside world. In this study or research, the strategy for modeling is utilized to show the performance and conduct or behavior of a real biosphere.
Researchers made a model or an artificial situation that can uphold living things. It has a scaled-down model of a tropical forest, a grassland, a sea with a coral reef, a desert, and a mangrove biosphere. In these conditions, a wide range of animal varieties was contained. Furthermore, a group of eight individuals additionally fixed themselves inside it.
Answer:
0.5
Explanation:
Density=mass÷volume
So the density of the mineral is 3÷6 which equals 0.5
