As relevant to the question here, an object’s mass refers to an intrinsic property of the object while weight refers to a force that depends on the local gravitational field. So, if an object moves between planets with different gravitational pull, the object’s weight would change but its mass would not.
The third option would thus be the correct one (the object of an invariant mass would have a lesser weight on planet B than on planet A).
Answer:
Diffusion occurs when particles move from an area of high concentration to an area of low concentration. The factors affecting rate of diffusion are: concentration, temperature, mass of the particle and properties of the solvent in which diffusion occurs. Faster movement equals faster diffusion.
Explanation:
The statements that describe steps taking place in the nitrogen cycle are
- Many biotic and abiotic factors play a role in recycling nitrogen ( A )
- Farming practices and chemicals lead to a build-up of nitrates in the soil ( E )
Nitrogen cycle is biochemical process whereby nitrogen is converted to various chemical forms as it passes through the atmosphere, Marine and terrestrial ecosystems .
Nitrogen cycle undergoes four ( 4 ) important processes which are :
- Fixation
- Ammonification
- Nitrification and
- Denitrification
Hence we can conclude that The statements that describe steps taking place in the nitrogen cycle are :
Many biotic and abiotic factors play a role in recycling nitrogen and
Farming practices and chemicals lead to a build-up of nitrates in the soil

It acts as a reactant in a chemical reaction.
Answer:
1. sympathetic
2. parasympathetic
Explanation:
The sympathetic division of the autonomic nervous system triggers the release of stress hormones from adrenal medulla under emergency conditions. There is a series of physiological responses such as increased heart and breathing rate, an increased flow of blood to skeletal muscles, dilation of pupils, etc. These events helped Nasim to fight the stress conditions.
Once she was relieved, the parasympathetic system is activated that shut down the physiological responses generated by sympathetic division. It slows down the breathing and heart rate and triggers the digestion and absorption of nutrients to restore the energy level of cells.
