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.

In general, the frequency of crossing over between two linked genes depends on what?
How far apart they are on the chromosome
The characteristics that the genes code for
Whether the genes are dominant or recessive
The phase of meiosis in which the crossing over occurs
Answer:
Crossovers during meiosis happen at more or less random positions along the chromosome, so the frequency of crossovers between two genes depends on the distance between them.
The closer two genes were to one another on a chromosome, the greater their chance of being inherited together. In contrast, genes located farther away from one another on the same chromosome were more likely to be separated during recombination.
[tex]\huge{\color{magenta}{\fcolorbox{magenta}{black}{\huge{\color{white}{\fcolorbox{aqua}{black}{✿ᴀɴsᴡᴇʀ✿}}}}}}[/tex]
If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency. Genes that are closer together undergo fewer crossing over events and non-crossover gametes will exceed than the number of crossover gametes.

Answer:
Anticholinergic drugs are common ingredients in antidiarrheal medications because they significantly decrease intestinal motility and secretions.
Anticholinergics drug class is used to slow the movement of gi contents, causing a decreased ability for muscles to contract.
What are anticholinergics?Anticholinergics are a type of medication which blocks the action of a neurotransmitter known acetylcholine. Acetylcholine transfers signals between cells that affect specific bodily functions. As anticholinergics can affect a variety of functions, including digestion, urination, salivation, they can help treat many conditions.
The medication blocks acetylcholine from causing involuntary muscle movements in the gastrointestinal tract, lungs, urinary tract, and other areas of the body.

Enzymes have an attachment site called the __ site for the __ to join
Answer:
Enzymes have an attachment site called the active site for the substrate to join. Consequently, what is catalytic site of enzyme? In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
Enzymes have an attachment site called the active site for the substrate to join. Enzymes then convert the substrate into a product and release it from the active site.
What is an enzyme, and how does it function?
The enzyme has an active site where the substrate binds and then forms a noncovalent bond with the enzyme. As a result of this binding, the product is formed by different modifications.
The enzyme has another site apart from the active site, and that is called the allosteric site. This site is occupied by regulators that can regulate the enzyme by enhancing or suppressing the enzyme's activity.
The enzyme is made up of amino acids by the process of translation, but not all enzymes are made up of amino acids. Apart from the polypeptide chain, there are molecules such as zinc, magnesium, etc. at the catalytic site to help enzymes make the product.
Hence, enzymes have an attachment site called the active site for the substrate to join.

How could we slow down or help stop ocean acidification?
Answer stop using plastic.
Explanation: Hello! My name is Hunter and I am a Marine Biologist within the state of Juno beach Fl, I work at a marine center located there and I teach people about Marine life animals and some ways to approach animals, and more. And here are some ways you can slow down or help stop ocean acidification. If you care for marine animals take the decision to use glass, wooden, bamboo, or metal etensals. This helps instead of using plastic because most plastic ends up being in the ocean. studies show that about 150 animals die a day from inhaling plastic. Second, Most plastic has acid or a type of smell like the rubber gloves at the dentist, That smell and taste can be extremely toxic and deadly for marine life animals. Third, If you are a fisher or you work on a supply boat, Make sure your oil on the boat doesn't leak, Just because you call someone and they put a net around the oil doesn't mean animals can't get under the net. Animals in the ocean are free, If you're on or work on a supply boat, Make sure to check your oil frequently. Oil leaks happen more than you think if you are not experianced! I hope this helped and how WE can slow down or reduce acdification. Have a great rest of your day or night.
Thoroughly analyze the alguments made in the article regarding potential
evolutionary links between the australopithecines and the ancestors of
the genus Homo. What evidence is provided by the author to conclude
that the later paranthropoids were not direct ancestors of modern
humans? Is this evidence sufficient to support his claim? Why or why not?
Extinct species of hominins known as Australopithecus may have been the ancestors of modern humans (Homo sapiens). The first fossils, which were found in South Africa, are referred to as Australopithecus.
After almost a century of findings, the first species to be called Australopithecus was given that name in 1925, and today, paleoanthropologists may access a sizable collection of fossilized hominin remains from Africa. High-quality fossils of early human species are still very hard to find despite decades of research, making it even more important for scientists to continue finding them in order to better understand the biology and variety of Australopithecus. The Great Rift Valley in eastern Africa, the limestone caves of South Africa, the sedimentary deposits of the Chad Basin, and the Djurab Desert are the only places on earth where geological circumstances are favorable for the preservation and excavation of hominid fossils (an arid region in central Chad).Learn more about the Australopithecus with the help of the given link:
