How atoms and molecules are important to cell processes?
hoa [83]
<span>Cells metabolise these macromolecules into smaller components which will be later used namely, carbohydrates, proteins, fats and nucleic acids.
These macromolecules could either be amino acids, proteins or nucleic acids. They are responsible for the chemical changes and reactions that affects largely the cell and its composition. Take for instance the cytoplasm of the cell where these organelles are settled. These simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. In intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components. </span>

4. Discuss the difference between solar flares and CME's.
brilliants [131]

Answer:

CMEs are giant clouds of particles from the Sun hurled out into space, while flares are flashes of light—occurring in various wavelengths—on the Sun.

All three occur in the corona. The biggest difference is the cause. The solar wind is a constant flow of particles from the sun’s corona due to their high energy gained from the sun’s interior, it’s like being boiled off. CME’s and flares are the result of “explosive” releases of energy from the sun’s magnetic field.

One can think of the explosions using the physics of a cannon. The flare is like the muzzle flash, which can be seen anywhere in the vicinity. The CME is like the cannonball, propelled forward in a single, preferential direction, this mass ejected from the barrel only affecting a targeted area.

Refer to Animation: Base Excision Repair. In the example in the animation, uracil is incorrectly paired with guanine. What is th
REY [17]
<h2>Mutation will occur </h2>

Explanation:

Base excision repair operates for small DNA damage such as deaminated bases

  • DNA glycosylase plays an important role in cleavage of glycosidic bond of abnormal base (does not cleave phosphodiester bond)
  • Uracil is incorrectly paired with guanine then mutation will occur
  • The original GC base pair will change into AT base pair(transition of GC to AT)
  • Transition is a mutation in which one purine(adenine or guanine) is substituted for other or one pyrimidine(cytosine or thymine or uracil) is substituted for other
