Muscular system, gastrointestinal system and excretory system are required for the process.
<h3><u>Explanation:</u></h3>
Cheetos is a nutrient rich diet which is actually a snack. Its a hard food, so needs to be chewed which uses the muscular system for chewing. The muscles of jaw like masseter and temporalis are required.
Now as the Cheetos are crunched, they need to be digested into finer particles and finally into the absorbable particles. This uses the gastrointestinal system. The enzymes digest the food and the villi of small intestine helps in the absorption.
The absorbed food are metabolized in liver and some excretory products are produced. They are excreted using the excretory system.
Answer:
Option C = ice is less dense than liquid water because the molecules in ice are further apart.
Explanation:
When water is cooled below 0°C, ice is formed. In ice form water molecules have more hydrogen bonds. When temperature increases, hydrogen bonds between water molecules breaks and water gets melt.
In liquid form water molecules are get closer to each other as compared to the ice form. This is the unusual behavior of water as compared to the other substances in solid form.
In ice form water molecules are strongly bonded but the distance between the water molecules are more or we can say that their are empty spaces present between water molecules that's why ice is less dense than the liquid water.
Density:
It is define as mass per unit volume.
The less dense substance float on the surface of water while the substance more dense than water or sink in it.
For example:
Take the two equal amount of blocks one is made up of styrofoam and one is made up metal. Put these two blocks in to water. The block made up of metal will sink while the other made up of styrofoam will float on the surface of water because of difference in densities. The styrofoam is less denser than water while metal more denser then water.
The answer is a Volcanic Island Arc
Explanation:
1. What is a longitudinal wave?
- A wave vibrating in the direction of propagation
- This is also called "pressure waves"
- Example: Sound waves, ultrasound waves
2. When you hear a sound wave through the air, what are you detecting?
We are detecting the sound wave through the ears. There is a part called ear drum present inside the ear and it turn contains 3 bones which makes us to hear the sounds. When sound waves enters, the ear drum vibrates.
3. In which direction does the material vibrate, as energy travels through it?
The direction is perpendicular to the direction of energy transport.
4. When a wave transmits, or transfers, energy, do the individual molecules or particles also move from one end to the other?
Yes, the particles move from one end to other.
Answer:
Free nitrogen is important for the living organism becuse nitrogen helps to build the structure of various biomolecules such as amino acids,proteins and nucleic acids such as DNA and RNA.
Explanation:
Importance of free nitrogen in case of animals
Nitrogen is an important constituent of porphyrin ring present in the hemoglobin protein protein which play a significant role in the transport of oxygen and carbon dioxide gas.
Nitrogen is also important in cell growth,repair and tissue development.We cannot intake the atmospheric nitrogen.Nitrogen is acquired by us through the consumption of protein rich diet.
Importance of free nitrogen in case of plants
Nitrogen is an important component of the chlorophyll pigment present in the leaves which helps in photosynthesis a process that deals with the formation of glucose by the utilization of sunlight.
Some parts of the energy rich compound Adenosine triphosphate is made up of Nitrogen.
