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.

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.

What is the name of the microtubule-organizing center found in animal cells that is present during all phases of the cell cycle?
Answer:
It is called the Centrosome
Explanation:
The Centrosome is known as the main microtubule organizing center of animal cells, the Centrosome participates in the organization of the microtubule network within a cell. It's formed with two centrioles surrounded by a matrix of proteins called pericentriolar material.
The cell cycle includes various phases. The microtubule-organizing center found in animal cells is present during all phases of the cell cycle are centrosomes.
What is a centrosome?A centrosome is a cellular organelle which is involved in the process of cell division.
Before cell division, the centrosome duplicates, as division begins, the two centrosomes starts moving to opposite ends of the cell.
It is the main microtubule-organizing center (MTOC) of animal cell. It is also a regulator of cell cycle progression.

Which principle of heat exchange is the most important explanation for why birds look larger in colder weather because they fluff their feathers?.
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.

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.

Hydrotropism is the root motion toward the water source. In the example, Stimulus: Water. Tropism: Hydrotropism. Response: Roots growth toward the water leak.
What is Tropism?In botanic tropism refers to the biological response of the plant during its development to an external stimulus. These responses are usually noticed as plant motion, forward to or away from the stimulus source.
Stimuli can be good or bad for the plant, and depending on this, the plant will try to get closer or farther. According to this, Tropism can be either positive or negative.
Positive tropism ⇒ the plant moves forward to the stimuli sourceNegative tropism ⇒ The plant moves away from the stimuli source

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.

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.
