The correct answer is C. Weathering

Explanation:

The term "weathering" refers to the breaking down or alteration of rocks, minerals and similar that are on the surface. This occurs due to different factors such as physical forces for example pressure or air; chemical reactions such as extreme temperatures or due to organisms. Additionally, weathering leads to changes on rocks and in general terms on soil and the surface. Also, this differs from erosion because it does not imply the movement of oil or rocks but occurs in one place. According to this, it is weathering the term that describes the breaking down and changing of rocks.

What is the role of oceans in the carbon cycle?

Maslowich

Answer:

Don't worry I'm here to help

Explanation:

The ocean plays an important part in the carbon cycle.

Overall, the ocean is called a carbon 'sink' because it takes up more carbon from the atmosphere than it gives up.

Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter.

Glad I could help!!

Part A Which of the following features is a significant difference in the function of DNA polymerases versus RNA polymerases? Se

Artist 52 [7]

Answer:

The correct answer is RNA polymerase does not require a primer to add new nucleotides.

Explanation:

RNA polymerase is an important enzyme of transcription process that deals with the formation of mRNA from DNA. unlike DNA replication, transcription process does not require any RNA primer to carry out the synthesis of mRNA in 5'→3" direction.

RNA polymerase use coding strand of DNA molecule as a template to synthesize new mRNA molecule from that parental DNA molecule.

Which statements about the Hubble Space Telescope are true?

ankoles [38]

<h2 /><h2> $Answer-$ </h2>

The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory (1991–2000), the Chandra X-ray Observatory (1999–present), and the Spitzer Space Telescope (2003–2020). The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.

The β-oxidation of odd-numbered FAs presents a small problem in that once most of the oxidation has occurred, the last component

IrinaK [193]

Answer:

Maybe that your question is incomplete, in the options following the statement listed none is correct ...

The procedures would have the following order:

1-Propionyl-CoA is converted to Methylmalonyl-CoA thanks to the enzyme Porpionyl-Carboxylase CoA which adheres to a carboxyl modifying the chemical structure (This enzyme depends on ATP, biotin and bicarbonate, to carry out the reaction).

2-Then, Methylmelanolyl-CoA is adhered to a radical, thanks to the enzyme methylmalonyl-CoA racemase, thus generating (R) -methylmalonyl-CoA as a product of the reaction.

3- And finally, (R) -methylmalonyl-CoA is converted to succinyl-CoA, an intermediate of the tricarboxylic acid cycle, by the enzyme methylmalonyl-CoA mutase, which requires cobalamin to catalyze carbon-carbon bond migration.

4-The mechanism of the methylmalonyl-CoA mutase begins with the cleavage of the bond between the 5 'of CH2-5'-deoxyadenosyl and cobalt, which is in its 3 + (III) oxidation state, which produces a 5'-radical. deoxyadenosil and cabalamin in the state of reduced oxidation Co (II)

Explanation:

Propionyl-CoA is important to know that it can come from different biological rations of the organism, such as: beta oxidation (of odd-chain fatty acids), the metabolism of isoleucine and valine and As a product of α-ketobutyric acid, which in turn it is a product of the metabolism of threonine and methionine.
