The DNA chain that acts as the concrete for transcription is sense.
What is DNA sense?
DNA Sense is a DNA strand with a 5′ → 3′ direction that has the same nitrogen base sequence as mRNA (except T is replaced by U). Because these strands have the same sequence as mRNA, they are referred to as coding.
While Antisense DNA is a DNA strand with a direction of 3′ → 5′ or is called a negative strand (-). This strand plays a role in transcription to form mRNA so this strand is called a template. The 3′ → 5′ direction is based on this DNA strand during the transcription process by the RNA Polymerase enzyme.

the bacterium clostridium botulinum secretes botulinum toxin, neurotoxin. the toxin blocks the release of acetylcholine from the axon terminal of a motor neuron. explain how the toxin binding would change the normal sequence of events at the neuromusclar junction
The motor neuron is bound by botulinum toxin, which inhibits acetylcholine from being released into the synaptic cleft. Due to the lack of neurotransmitter to bind to the ion-channel receptor on the muscle cell motor end plate, this hinders the beginning of an end-plate potential.
The bacterium Clostridium botulinum, an anaerobic, gram-positive, spore-forming rod frequently found on plants, in soil, water, and the digestive tracts of animals, produces the neurotoxic protein known as botulinum toxin, or BoNT.
Botulinum toxin causes flaccid paralysis by preventing the release of the neurotransmitter acetylcholine from axon terminals at the neuromuscular junction. The toxicity is what leads to botulism.

What are the advantages and disadvantages of variation to the survival of orangutans?
The advantages and disadvantages of genetic variation to the survival of orangutans are:
Advantages:
Because of variation, organisms can evolve to survive in challenging environments and become more resistant to diseases. It also fosters diversity.Disadvantages:
Negative effects, such as genetic disorders and diseases, are another potential drawbackWhat is genetic variation?
DNA sequence variations among members of a population are referred to as genetic variation. Sperm and egg cells, as well as somatic (all other) cells, are subject to variation.Three separate processes contribute to genetic diversity: gene recombination, gene migration, and mutation. Genetic variety and evolution are propelled by mutation. Base substitutions, deletions, and insertions are the different kinds of DNA mutations.Due to deforestation, illegal hunting, and forest fires that have decimated orang-utan wild populations, one of the most thorough genome analyses of orang gutans to date has revealed that its tiny populations are surprisingly genetically diverse.

physical properties of matter ability to be stretched into wire without breaking
Answer: Ductility
Explanation:
The term that is ductility is the Capacity of a material to deform permanently that is stretch, bend, or it can be spread in response to stress. And therefore we can say that it fractures easily. When a material specimen is stressed then it plastically deforms we can see elasticity at first that is above a certain deformation which is known as the elastic limit of the deformation becomes permanent.
The materials that are easily deformed even without breaking when they are put under mechanical pressure are considered to be malleable. The materials that are easily deformed when they are put under tensile stress are considered to be ductile.
The word malleable comes from the latin medieval malleability which itself came from the original Latin malleare that is meaning "to hammer."
Since these materials do not break while it is being deformed that they can be forced into different shapes or sheets that are thin. This can be done by hammering as well as rolling or pressing.
A common very example for this is of a material that is malleable is gold which is often compressed into a leaf of gold for use in art as well as architecture, jewelry, and even food. There are other malleable metals which include iron, and copper, aluminum, silver, and lead, as well as the transition metal zinc at certain temperatures. There are many materials that are very malleable and are also very ductile, and it generally leads to an exception which is with low ductility and high malleability.
They are closely related to the concept of malleability that is said to be ductility. While the term that is malleability has to do with compressive stress or mechanical pressure and ductility relates to tensile stress or mechanical stretching.
Something we notice is ductile which is sometimes also known as tractile that can be easily stretched or drawn out into a thin wire. Copper is a very good ductile material and is a very good example of both malleability and ductility which is able to be pressed and rolled into sheets as well as stretched into wires.
The metals are often mixed as we mix the alloys to improve their physical properties. There is high-tensile steel which is an example of an alloy that has higher ductility than any of its component metals. And it is said to be often used in airplanes and cars and other engineering applications.

2) increased UV insolation
3) melting glaciers and ice caps
4) increasing sea levels
All of the following are negative consequences of enhanced greenhouse gas effects except melting glaciers and ice caps as it is a part of a positive feedback loop.
This positive feedback loop, which also actively raises temperatures, especially in the Arctic areas, has a substantial impact on the local ecology.
In comparison to other planets, the earth's temperature is one of its most striking and distinctive features. There are many different biological forms on the globe, and they all survive. The current increase in global warming on Earth is a result of a number of factors, including human activity, industrial waste, and trapped greenhouse gases.
Global warming has caused the ice sheets to begin to melt. As the white snow sheets melt away, the black ocean water, rocks, and flora hidden behind them are more easily seen; this phenomenon is regarded to create a positive feedback loop. Since the ice sheets are white, most of the incident light is reflected when they melt. The local ecology is significantly impacted by this positive feedback loop, which also actively elevates temperatures, particularly in the Arctic regions. Darker ocean water has a tendency to absorb more radiation, which boosts temperatures even more and speeds up global warming.
