A telescope in space can focus on any object while a telescope on the ground cannot focus on the object it is on
Answer:
1. Photosynthesis releases oxygen gas as a product.
2. Subtracting cellular respiration from gross primary productivity
3. True
Explanation:
1. Photosynthesis is the process by which autotrophic organisms synthesize their food in form of sugars in the presence of sunlight. Photosynthetic process combines carbon dioxide (CO2) and water (H2O) to form glucose (C6H12O6) and oxygen gas as products. The equation is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
2. Net primary productivity, denoted by NPP, refers to the amount of biomass present in an ecosystem. It can be calculated by subtracting the amount of CO2 lost via cellular respiration from the amount produced called Gross primary productivity (GPP). That is;
NPP = GPP - cellular respiration
3. The process by which organic matter is synthesized from inorganic ones by organisms called AUTOTROPHS or PRIMARY PRODUCERS is called PRIMARY PRODUCTIVITY. Examples of autotrophic organisms are green plants, algae etc. Hence, in an ecosystem that have a high primary productivity, there would be a rapid rate of conversion of solar energy to biomass via PHOTOSYNTHESIS.
The density of an object is the mass of the object divided by its volume.
Remember that mass of an object is the amount of matter that the object contains. The unit for mas in the standard international unit system is the kilogram (kg), which is 1000 grams; the unit of mass in the US is the pound (lb), which is 453.592 grams.
The volume of an object is the amount of space that the object occupies. The unit for volume in the standard international unit system are the cubic meter (
) and the liter (L); 1 cubic meter equals 1000 liters.
The density of an object is the quantity of mass of the object per unit of its volume. The unit for mas in the standard international unit system is the kilogram per cubic meter (
).
Now, lets create our hypothesis:
If the mass and the volume of and object are known, then its density can be calculated dividing the object's mass by its volume.
We can conclude that the density of an object can be obtained by dividing its mass by its volume.
The answer is C upwards at 20cm
If you'r referring to some objects, it means that the mass of the object is less than the water so it floats. If the mass of an object is greater than the mass of the water, it will sink. Compare it to a balloon, helium makes it rise, while normal air makes it sink.
