What qualities of metamorphic rocks make them very useful and desirable for building?

Biology

Slate starts out as shale under the surface of the Earth before its metamorphosis. It is typically gray in color and splits along long flat planes. It is also does not allow water or other liquids to pass through it. Slate is most often used as a roofing material, decorative gardening stone and a base for snooker tables. In the Victorian era, it was commonly used as a writing board.

Marble is another one of the metamorphic rocks and is a metamorphosed limestone. It has a hard crystalline rock appearance and was the stone of choice in ancient Greece. In fact, more than 22,000 tonnes of marble were used to build the ancient Greek Parthenon and marble remains a popular building and sculpture material today. It can also be ground down to make cleaning products or soaps.

Schist is another metamorphic rock that is formed from either mud or shale. However, it is formed at a much higher temperature than slate is. Schist is a fairly weak rock so it does not make for a good building material. It is used for paving and occasionally sculpture.

Which natural methods remove CO2 from the atmosphere? respiration ofa. living organisms B.photosynthesis by plants C.evaporation
zysi [14]

Answer;

A) respiration of living organisms.

D)absorption of CO2 from the atmosphere by ocean water.

Explanation;

-The level of carbon dioxide in the atmosphere is maintained by several processes, including photosynthesis, respiration and combustion.

-Green plants remove carbon dioxide from the atmosphere by photosynthesis. Living organisms - including all plants and animals - release energy from their food using respiration. Respiration and combustion - burning - both release carbon dioxide into the atmosphere.

During photosynthesis, the energy used to pump protons comes from ___________, whereas in cellular respiration it comes from ___
Annette [7]

During photosynthesis, the energy used to pump protons comes from ______light_____, whereas in cellular respiration it comes from ______NADH/FADH₂_______.

<h3>What are the steps in photosynthesis?</h3>
  1. The first step in photosynthesis is the absorption of light by chlorophyll bound to chloroplast thylakoid proteins. The absorbed light energy is used to remove electrons from electron donors such as water to form oxygen.
  2. The electrons are then transferred to the primary electron acceptor, quinine (Q.). Electrons are further transferred from the primary electron acceptor to the final electron acceptor (usually NADP⁺).
  3. Proton transfer from the thylakoid lumen to the stroma via the F₀F₁ complex generates ATP from ADP and Pi.
  4. The NADP and ATP produced in steps 2 and 3 provide the energy, and the electrons power the process of reducing the carbon to a six-carbon sugar molecule.

The first three steps of photosynthesis, are directly dependent on light energy and are thus, called light reactions, while the reactions in the last step are independent of light and thus are termed dark reactions.

Hairpins often form at palindromic sequences in single strands of either rna or dna. however, several key features differentiate
AlekseyPX
Hairpin like structures are formed in both DNA and RNA but are common in RNA than in DNA. This is because DNA can be double stranded or single stranded while RNA is generally single stranded structure that can be double stranded only when it forms a hair pin like structure.
The features of hairpin structure in RNA are as follows:
1. This structure is a building block of many secondary structures of RNA.
2. The termination sequence during transcription also forms a hairpin loop like structure.
3. tRNA also forms a hairpin loop like structure and helps in the process of translation.
