Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food. A byproduct of photosynthesis is oxygen. Scientists believe that phytoplankton contribute between 50 to 85 percent of the oxygen in Earth's atmosphere.

disa [49]

The amount of glucose in each ml of their blood will be 0.00138 g.

<h3>Blood glucose concentration</h3>

The concentration of glucose in the person's blood is 1.38%.

This means that there is 1.38 g of sugar per Liter of blood.

1 Liter of blood contains 1.38 g of glucose, and there is 1000 mL in 1 Liter of blood.

1000 mL contains 1.38 g

1 ml contains = 1.38 x 1 / 1000 = 0.00138 g

This means 0.00138 g of glucose will be present in every 1 mL of the person's blood.

As white light passes through a prism, the light is separated into the different colours of light that we see and this is called the visible spectrum. Each colour of light has a different wavelength. The wavelength is inversely proportional to the energy of that light. As the wavelength increases, the energy decreases and vice-versa. The relationship is:

E = h/λ, E is energy, h is Planck's constant, and λ is the wavelength.

Therefore, the answer is B) different amounts of energy in white light.
