Scurvy and rickets are micronutrient deficiency diseases due to a lack of certain vitamins or minerals in the diet. Scurvy is caused by vitamin C deficiency and rickets by vitamin D.

<h3>What are proteins and carbohydrates?</h3>

  • Proteins and carbohydrates are the macronutrient in the body and are sources of energy. Proteins are made of amino acids linked together by the peptide bond and carbohydrates are made of carbon, oxygen, and hydrogen.

  • Breathing is a biological process that involves exhalation and inhalation, while respiration is a chemical process that occurs in body cells and tissues.

  • The cerebrum and cerebellum are the parts of the brain involved with different functions. The cerebrum of the forebrain is involved with mental, motor, and sensory functions, while the cerebellum is involved with posture, balance, and coordination.

  • The infectious disease gets transmitted to another person by viruses, bacteria, fungi, etc., and non-infectious are non-communicable disease that includes age, deficiency, etc.

Why can’t solids flow
Annette [7]

Answer:

basically they have too much mass in them

Explanation:

They are held tightly together by strong forces of attraction. They are held in fixed positions but they do vibrate. Because the particles don't move, solids have a definite shape and volume, and can't flow. Because the particles are already packed closely together, solids can't easily be compressed.

Water initially at 200 kPa and 300°C is contained in a piston–cylinder device fitted with stops. The water is allowed to cool at
netineya [11]

Answer:

Δu=1300kJ/kg  

Explanation:

Energy at the initial state

p_{1}=200kPa\\t_{1}=300^{o}\\u_{1}=2808.8kJ/kg(tableA-5)

Is saturated vapor at initial pressure we have

p_{2}=200kPa\\x_{2}=1(stat.vapor)\\v_{2}=0.8858m^3/kg(tableA-5)

Process 2-3 is a constant volume process

p_{3}=100kPa\\v_{3}=v_{2}=0.8858m^{3}/kg\\u_{3}=1508.6kJ/kg(tableA-5)

The overall in internal energy

Δu=u₁-u₃

We replace the values in equation

Δu=u₁-u₃

=2808.8kJ/kg-1508.6kJ/kg\\=1300kJ/kg

Δu=1300kJ/kg
