What are pigments such as chlorophyll and carotene used for?; What are pigments used for in plants?; Why do plants need pigments
mash [69]

In regions of the electromagnetic spectrum where chlorophylls a and b are unable to absorb light, the plant can absorb light thanks to carotenoids and other auxiliary pigments.

<h3>What are pigments such as chlorophyll and carotene used for?</h3>
  • Carotenoids absorb energy from sunlight similarly to chlorophylls. To increase photosynthesis, they then transfer the energy to chlorophyll molecules.
  • Carotenoids function as antioxidants in all living organisms. The oxidation reactions that can harm cells can be slowed down by chemicals known as antioxidants.
  • Insects, birds, and other animals are drawn to pigments as visible cues for pollination and seed dissemination. Plants are also shielded by pigments from UV and visible light harm (Tanaka et al., 2008). The human diet includes many fruits that are high in pigment.
  • Chlorophyll and other pigments, which absorb the sun's rays to produce food for the organisms, are necessary for photosynthesis.

Find the density of a cube on Earth that weighs 1.5 kg and has a side-length of 10 cm.
Inga [223]

Answer:

1.5g/cm³

Explanation:

density=mass÷volume

mass= 1.5kg (<em>c</em><em>h</em><em>a</em><em>n</em><em>g</em><em>e</em><em> </em><em>i</em><em>n</em><em>t</em><em>o</em><em> </em><em>g</em>) = 1500g

volume of the cube = 10×10×10 = 1000cm³

density= divide 1500g÷1000cm = 1.5g/cm³

<h2>Density= 1.5g/cm³</h2>

This increase in blood pHpH due to hyperventilation disrupts O2O2 transport by causing the deprotonation of various residues of
Genrish500 [490]

The question is incomplete as it does not have the options which has been provided in the attachment.

Answer:

1. sudden decrease

2. Respiratory alkalosis

Explanation:

Hyperventilation is a condition caused by the excess removal of the CO₂ from the blood which leads to the decrease in the pCO₂ of the arteries.

This decrease can cause fainting and death of the individual due to the malfunctioning of the body parts, especially the brain.

The decrease in the CO₂ amount of the blood causes the formation of bicarbonate and H⁺ ions which leads to respiratory alkalosis.

Therefore the selected options are correct.

During which change of state would the volume of a substance increase the most?
Alika [10]

Answer:

The most state has the high volume is the gas state.

So here the answer is vaporization!!!!

Explanation:

The most state has the high volume is the gas state.

So here the answer is between vaporization and sublimation???

and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas

and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°

here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.
