The law of conservation of mass states that mass is neither created nor destroyed by chemical reactions or physical transformations. according to this, the mass of the products must equal the mass of the reactants.
B: used up in the process
When photosynthesis occurs the plant takes in sunlight and CO2 and converts it into (C6H12O6) or sugar and O2
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.
It has a closed circulatory system. because we have a closed circulation system. and all that means is that we have veins and a heart. <span />
