Which repair process in e. Coli uses visible light to repair thymine dimers?.
Answer:
photoreactivation repair
Explanation:
Photoreactivation utilizes the enzyme photolyase to break the bonds formed during pyrimidine dimerization. A thymine dimer produced by UV irradiation is bound by photolyase. Visible light energy is absorbed by photolyase and is redirected to break the bonds forming the dimer.
In addition to bacteria, this DNA repair mechanism is also found in single-celled eukaryotes, plants, and some animals such as Drosophila.

Since forces cause a change in motion or state of a body, friction is a force which opposes motion of an object over another.
What is frictional force?Frictional force or friction is the force that opposes the relative motion of one object over another at their surface of contact.
The two types of friction are:
static friction andkinetic frictionRough surfaces experience the greatest friction while smooty surfaces experience the least friction.
Hence, friction can be reduced by lubrication or polishing.
Based on the property of forces and friction:
Force is defined as a push or pull that starts, stops or changes the direction of a moving object.Friction is a force that opposes motion between two surfaces sticking or touching together.A sandy floor has the greatest frictional force among these surface.Friction is a force that opposes motion. It acts in the opposite direction of a moving object. Friction is a force that occurs when surfaces touch each other. Rolling friction is produced when an object rolls over a surface is produced.Rolling friction is produced when an object is rolled on a surface. Round objects like a Ball produces rolling friction.Riding a bicycle and using of wheelbarrow (kariton) are examples of rolling frictionA soccer ball rolling on the ground is an example of rolling friction.Sliding friction occurs between moving objects and a liquid or between an object moving in the air.Static Friction occurs when there is more force needed to travel an object in a surface than rolling Friction.A train going around its tracks is rolling frictionSliding friction opposes the sliding of objects over a surface.Mucus produced by snails, help them move along the ground because Mucus reduces friction.Therefore, it can be concluded that generally, friction opposes motion of an object over another.

How does adding carbon dioxide to the ocean
affect its pH?
Provide an explanation for the results (or what should have happened) using SCIENTIFIC REASONING
Explanation:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

The section of DNA being used to make the strand of mRNA is known as the transcription unit.
What are transcription units?Transcription units are base sequences of DNA that make up a single mRNA molecule during the process of transcription.
During gene expression, genes are first transcribed to genetic codes in mRNA molecules before being translated to their respective proteins.
Each unit of transcription represents a gene along with non-coding base sequences in DNAs, otherwise known as introns.

Which of the following is least involved in the mechanical breakdown of food, digestion, or absorption?.
Answer:
Esophagus
Explanation:
In the digestion and absorption of food, the esophagus is the least involved.
It is a part of the digestive system, but all it does is simply pass the food down to the stomach.
The one that is least involved in the mechanical breakdown of food, digestion, or absorption is esophagus. The correct option is d.
Even though it is a vital component of the digestive system, the esophagus plays a much smaller role in the mechanical digestion of food than the other alternatives.
A muscular tube called the esophagus moves food from the mouth to the stomach by a process known as peristalsis, which calls for repetitive muscle contractions.
Its main job is to push food down the digestive tract so that it can travel more easily. Food is mostly mechanically broken down in the mouth while being chewed by the teeth and in the stomach while being churned by muscles.
The majority of digestion and nutrient absorption occurs in the small intestine.
Thus, the correct option is d.

What type of muscle assists an agonist by causing a like movement or by stabilizing a joint over which an agonist acts?.
Answer:
The correct answer is a synergist.
Explanation:
The muscles that provide movement in the musculoskeletal system act in groups or pairs, such as the hamstrings and quadriceps, or the biceps and triceps. An agonist, often known as a primary mover, is a muscle that works.
Synergists are muscles that assist the prime mover by moving in the same direction and at the same time. Synergists provide a motion similar to that of the prime mover while also stabilizing the joints that hold the agonist in place for smooth movement.
As a result, the correct response is synergist.

Which of the following does water pollution affect: surface water, ground Water, or ocean water? A)Pollution affects surface water and ground water only.
B)Pollution affects surface water, ground water, and ocean water.
C)Pollution affects surface water and ocean water only.
D)Pollution affects groundwater and ocean water only.
Water pollution includes any kind of water masses or currents. Option B is correct. Pollution affects surface water, ground water, and ocean water.
What is water pollution?
Water pollution can be defined as the abnormal accumulation of strange elements in the water with harmful consequences to natural ecosystems.
Water pollution involves all the possible ways in which any water body can be contaminated with harmful elements.
The most damaging source of water pollution is human activities, producing the biggest damage to natural ecosystems.
Contaminating elements might be either gasses, solid material, or liquid material. Chemical elements, microbiota, heavy metals, and sediments affect all forms of life.
As said before, several sources can contaminate water masses, and they do it directly and indirectly.
Directly pollution occurs when a strange element is thrown directly into the water. They can be thrown directly into a river, a lake, the sea, or the ocean.
Indirect pollution occurs when pollutants travel from other places and contaminate other masses of water. For instance, a polluted river contaminates the lake where it ends. The lake pollutes the river that begins in the lake. This last river ends in the sea and takes all pollutants to the sea.
We can affirm then that water pollution affect surface water, ground water, or ocean water. Option B is correct. Pollution affects surface water, ground water, and ocean water.
