If a person experiences rapid breathing, muscle twitches, and perspiration when trying to quit using illegal opiates, he or she
Nuetrik [128]
<span>This person is experiencing common physical symptoms of what is called "withdrawals". Opiates, when used illegally, can be highly addictive. This drug targets the central nervous system (the brain, cardiovascular and respiratory systems) and contains opioid receptors that receive opiate drugs. Abusing this drug can disrupt a person's brain chemistry, leading to severe physical withdrawal symptoms as listed in the question.</span>

You try to generate E. coli mutants by inducing pyrimidine dimers through UV exposure to bacteria on Petri plates. You confirm t
spin [16.1K]

Answer:

The correct answer is option E. "direct repair using photolyase has removed many of the pyrimidine dimers from the DNA in an error-free manner, so there are fewer lesions for SOS repair to process".

Explanation:

Photolyase is a type of enzyme that catalyses DNA repair from damage caused by exposure to ultraviolet light. Photolyase requires activation by exposure visible light, particularly from the violet end of the visible spectrum. If the Petri plates of the bacteria exposed to UV are located in an incubator that is closely at a large sunny windows, it is very likely that the bacteria is performing direct DNA repair using its photolyase enzymes.

Water is a unique compound with properties which are elemental for the existence of life. List six of these properties and how t
Luba_88 [7]

Here, we are required to list six of the properties of water and how they are essential for the existence of life.

These properties include:

  1. Water is a universal solvent
  2. Water is highly cohesive
  3. Water is a Substrate for microbial proliferation.
  4. Water supports cellular structure.
  5. Water has considerable buffering capability.
  6. Water is involved in Catabolic and Anabolic reactions.

  1. Water as a universal solvent is evident in its extensive capability to dissolve a variety of molecules and consequently transport them has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. Biologically, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients such as water-soluble vitamins.
  2. The cohesive property of water molecules helps plants take up water at their roots. Cohesion also contributes to water’s high boiling point, which is vital in animals body temperature regulation.
  3. Water serves as a substrate for Microbial proliferation because microorganisms grow best in high moisture environment.
  4. Water supports cellular structure: Water is quite important in biological structures. Water fills cells to help maintain shape and structure. The water inside many cells (including those that make up the human body) creates pressure that opposes external forces, similar to putting air in a balloon thereby creating a cushion.
  5. Water has considerable buffering capability: water buffers cells thereby protecting them from the dangerous effects of acids and bases. Highly acidic or basic substances, like bleach or hydrochloric acid, are corrosive to even the most durable biological materials.
  6. Water is involved in Catabolic and Anabolic reactions: Water is directly involved in biochemical reactions to build and break down important components of the cell. Photosynthesis, the process in plants that creates sugars for all life forms, requires water. Water also participates in building larger molecules in cells.
