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.

__is when two genetic sequences bind together because of the hydrogen bonds that form between the base pairs ​
Anettt [7]

Answer:

I would say that it is the bond called complementary hydrogen bonds

Explanation:

The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 1 s. what is your acceleration?
GREYUIT [131]
A = change in velocity / time
so change in velocity = 13-7 = 6
so 6/1 =6:
acceleration = 6m/s^2

When molten candle wax solidifies is that a chemical reaction or not?l
andrey2020 [161]

Yes, when molten candle wax solidifies it is a chemical reaction

<u>Explanation:</u>

Basically Wax is crystalline so once the candle light melts it freezes taking back the solid state to the room temperature.

When the room temperature is below the freezing point, the liquid candle wax, turns into solid state again, therefore this process is called solidification. The process of freezing or solidification is a process when an object turns liquid and freezes back to solid state.

Indeed, Yes, when molten candle wax solidifies it is a chemical reaction

If you can answer as many of these as possible that would be great, will give thanks, 5 stars, and brainliest :)
alexandr1967 [171]

Answer:

  1. The nucleus of the atom as suggested by "nuclear" chemistry.
  2. Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons.
  3. An excessive amount of protons or neutrons.
  4. Periodic table, table O, and table N.
  5. Personal opinion question.
  6. The atomic number.
  7. It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge).
  8. Protons ---- element.
  9. Random, self-generated.
  10. Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass.
  11. Neutrons and Gamma radiation.
  12. Gamma radiation.
  13. Electrons and Beta particles.
  14. To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element.
  15. The number of protons because they are what define the identity of an element.

Goodluck!

According to the concept of entropy, what will likely happen to most molecules over time?.
Vsevolod [243]

They're going to fall apart.

<h3>What most molecules will likely experience over time?</h3>

A system's entropy cannot decrease unless heat is being lost from it. This indicates that entropy cannot decrease in a closed system (i.e., nothing enters or leaves, and that means nothing at all), so it must either remain constant or rise. Entropy can decrease, rise, or stay constant in an open system when movement between the system and its surroundings is conceivable. Both of these outcomes leave open the option of a constant state.

Entropy:-

The quantity of atom-alignment combinations that can exist in a system is known as entropy. The quantity of energy that cannot be used for work can also be calculated from an object's entropy.
