Your digestive system is responsible for your food being processed, your resperitory system is your breathing, and your circulitory system is your blood pumping. You would be able to burn your calories from cake by digesting your food into energy, your breathing would get your heart rate up because you are requiring more usage of your lung thus your heart rate rising, raising your blood pressure. This process causes calories to burn.

Why can't grass eat rabbits? (and I actually mean that)
Answer:
Are grass clippings from the lawn mower safe? You should never feed your bunny grass cuttings from lawn mowers. According to The Rabbit House, the heat of the blades and the cutting process causes changes to the grass making it ferment quicker leaving your bunny vulnerable to a poorly tummy.

Sound waves are produced when something is caused to reflect. vibrate. slow down. get warmer.
Answer:
B) Vibrate
Sound is created through vibration.
Sound waves are produced when something is caused to vibrate. When an object vibrates, it creates a disturbance in the surrounding air molecules, causing them to bump into each other and create a wave of pressure fluctuations. Hence option B is correct.
What are sound waves?Sound waves are a type of mechanical wave that transfers energy through oscillations of particles in a medium such as air, water, or solid material.
When an object vibrates or moves, it sets off a series of pressure waves in the medium around it, creating a disturbance that travels through the medium as sound.
The sound wave consists of compressions and rarefactions of the medium, where compressions are areas of high pressure and rarefactions are areas of low pressure.
The frequency of the vibration determines the pitch of the sound wave. For example, a higher frequency of vibration produces a higher-pitched sound, while a lower frequency produces a lower-pitched sound. The intensity of the vibration determines the volume or loudness of the sound wave.
Hence option B, vibrate is correct.

What is the crop plant that is suitable for this biofertilizer? Please elaborate.
Answer:
In nature, there are a number of useful soil micro organisms which can help plants to absorb nutrients. Their utility can be enhanced with human intervention by selecting efficient organisms, culturing them and adding them to soils directly or through seeds. The cultured micro organisms packed in some carrier material for easy application in the field are called bio-fertilisers. Thus, the critical input in Biofertilisers is the micro organisms.

1.Consider the four demographic characteristics relating to biotic potential
listed in the text: (1) usual number of offspring per reproduction, (2) chances
of survival until age of reproduction, (3) how often each individual
reproduces, and (4) age at which reproduction begins. Relate each factor to
the human population, rating each one as contributing to a high or low biotic
potential, justifying each rating. Then decide overall if humans have a high or low biotic potential
low biotic potential.
Based on the four demographic characteristics relating to biotic potential, humans generally have a low biotic potential.
What is biotic potential?Biotic potential refers to the maximum reproductive capacity or potential of an organism under optimum environmental conditions.
The demographic characteristics relating to biotic potential are:
usual number of offspring per reproduction- it contributes to low biotic potential because humans usually produce one offspring per reproduction chancesof survival until age of reproduction - contributes to high biotic potential since humans have high chances of survivalhow often each individual reproduces - contributes to low biotic potential since humans have usually reproduce at least once every nine months age at which reproduction begins - contributes to a low biotic potential since humans begin to reproduce at a later age of at least 12.Therefore, humans generally have a low biotic potential.
