Answer:
Explanation:
The ratio of the actual amount of water vapor present in a volume of air at a given temperature to the maximum amount that the air could hold at that temperature, expressed as a percentage.
Answer: The correct answer is black because the product of its side and mass is lower.
Explanation: Density of a substance is defined as the mount of matter that can be stored in a given volume.
Mathematically,
As, density is inversely proportional to the volume of the substance.
The substance will be more denser if it has less volume and it will be less denser if the volume is more.
We are given two cubes having different sides.
Volume of the cube is calculated by using the formula:
where, a = side of the cube.
Black: The side of this cube is 2 and volume will be = 
Yellow: The side of this cube is 3 and volume will be = 
As, the volume of black cube is less. So, this cube will be more denser.
Density of black cube: 
Density of Yellow Cube: 
Hence, black cube will be more denser because the product of its side and mass is lower.
Both of the statements that is given is false because when
the neuron is in resting potential, it is not in a permanent state and the
resting potential is negative. The charge of the neuron will be depending on
each activities or the charges it accumulates, that is why it is not true that
it does not change.
Answer:
Producers ( also called autotrophs) are the organisms that synthesize their own ( glucose) food using carbon dioxide and water in the presence of sunlight ( photosynthesis). They use energy from sunlight to convert it into chemical energy ( that is stored in the glucose). Autotrophs occupy the base of a food chain within the ecosystem as they are first trophic level for the energy transfer.
Decomposers ( such as bacteria and fungi that act on dead plants and animals) can recycle the organic matter back into the food web and biogeochemical cycles in the form of nutrients such as carbon and nitrogen.
Thus, the correct answers are-
1) Producers
2) Decomposer
3) Sunlight
4) Base
Sleep is the state of rest of the brain and body where physiological processes take place. More observably, the eyes close and the brain enters into a state of unconsciousness, either completely or partially. Moreover, sleep is guided by sleep/wake cycles and circadian rhythm.
