Mucosa secretes hydrochloric acid which chemically digests food. Once food is mixed with this secretion it is called chyme.
Chemical digestion is the process of changing the molecules of organic matter present in food from complex forms to simple forms with the help of enzymes.
Mucosa is a tissue that lines all cavities in our body such as the tongue and digestive tract. In the digestive tract there is tissue that lines the surface of the stomach so that the stomach wall is protected from gastric acid abrasion. Mucosa will secrete hydrochloric acid which will activate pepsinogen to become pepsin to digest food chemically, namely to break down proteins into proteoses and peptones.
Chyme is food that has been stirred and mixed with stomach acid sap and has become mush after peristaltic events. Peristalsis occurs when the wall of the stomach consisting of three layers of muscles contracts and causes a movement that stirs and mixes food with gastric juice.

a. rainfall
b. soil nutrients
c. wind
d. temperature
e. light
Tropical rain forests are not good for clearing to grow crops or animals, primarily because they are low in soil nutrients.
Tropical rainforests are those that have a climate similar to that of a tropical rainforest, meaning there is never a dry season and there is always at least 60 mm of precipitation per month on average.
The tropics include a wide range of soil types that are influenced by a number of factors, including climate, vegetation, topography, parent material, and soil age.
Although most tropical soils exhibit severe leaching and have few nutrients, some regions have productive soils. Ultisols and oxisols are two categories into which soils in tropical rainforests can be divided. Ultisols are well-weathered, acidic red clay soils that are lacking in important elements like calcium and potassium. Similar to oxisols, which are acidic, ancient, frequently reddish, severely weathered, and leached.

why does breathing become faster during exercise
Explanation:
When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.
Your body needs more oxygen and creates more carbon dioxide while you exercise because your muscles are working harder.

Meat tenderizer contain papain, a enzyme that digests proteins. How does this enzyme help in making meat tender?
Meat tenderizer, which is often used in the kitchen to soften tough cuts of meat, contains the enzyme papain. This enzyme is derived from the papaya plant and is able to break down proteins into smaller peptides and amino acids, which helps to make the meat more tender.
When meat is cooked, the proteins in the muscle fibers coagulate, or tighten up, which can make the meat tough and difficult to chew. Papain works by breaking down the proteins in the meat, which makes it easier to chew and swallow. It breaks down the bonds between the protein molecules, making them smaller and less resistant to chewing.
Papain works by cleaving peptide bonds in the meat proteins, particularly the tough, fibrous proteins such as myosin and actin. It works best at a pH of 6-7, and at moderate temperature around 40-50 Celsius. Papain can also work on breaking down connective tissues such as collagen and elastin, in the meat which are usually tough, making the meat more tender.
The amount of time that papain needs to break down the proteins depends on the pH and temperature, but also on the meat's own properties such as the age, the species and the cut. Papain is most effective when used for a period of time before cooking, allowing the enzyme to break down the proteins over a longer period of time. When papain is used for too short a time or at high temperature, it can cause the meat to become mushy.
In summary, papain is an enzyme that helps make meat more tender by breaking down the proteins in the meat, which makes it easier to chew and swallow. Papain also helps in breaking down the connective tissues in meat making it more tender. However, it is important to use meat tenderizer in the right way to get the desired result and not to overuse it which will cause the meat to become mushy.

Why does the speaker say it is important for her to offer her daughter choices? How does the speaker compare that to the importance of choice for the animals she cares for?
Summarize how Holly’s chimpanzee behaviors were different from the rest of the troupe.
What approach did the speaker and her team decide to take to help Holly? Give at least three specific examples.
What did the team observe about Holly and her troupe over time?
Why is offering choice a revolutionary concept at a zoo? Identify an element from what you read in the unit as to how zoos are changing that also serve the purpose of offering animals more choice.
Applying this learning to yourself. Identify a time when you might have resented feeling enclosed, but the offer of choices improved your outlook.
The speaker mentions some examples of activity bins that they used as enrichment materials for Holly. Identify two materials that you would be curious about giving Holly in a bin to see how she would interact with that material. Keep Holly’s safety in mind as you make your suggestions; avoid things that would endanger her or the troupe!
The unit mentions that an important factor in zookeeping is to give animals their space, as they are wild animals after all. How do you think zookeepers balance their need for research and helping specific animals, like Holly with respecting Holly’s need for “wild space.”
Because Holly doesn't interact socially with other animals, she exhibits different behavioral patterns from other animals. Innovative ideas will help animals connect with their surroundings more effectively in zoos.
What is Animal Behavioral Pattern?Animals' usual responses to a specific stimuli or circumstance are referred to as behavioral patterns in animals. Foraging, migration, courtship, communication, mating, and parenthood are a few examples of these patterns.
a)
The speaker on the TED talk show argues that giving her daughter choices is crucial because it helps her daughter grow in autonomy and self-determination. In a similar vein, the speaker is of the opinion that animals should be given the chance to display their natural behaviors through choice. Holly's chimpanzee habits were distinct from those of the rest of the troop because she was less social, spent more time by herself, and was less willing to investigate her surroundings. The speaker and her team made the decision to provide Holly with extra options in order to aid in her comfort and safety. They modified the design of the room and provided her with activity bins filled with various materials and objects for her to investigate.
b)
A novel idea in zoos is to give animals the freedom to display their natural behaviors and choose how to interact with their surroundings. Zoos are evolving by giving the animals more natural environments so they may explore their surroundings and make more decisions about how to behave. Zoos are now offering more naturalistic enclosures, which allow the animals to walk around more freely and decide where they want to go and what they want to do, as an illustration from the unit.
c)
When I was studying for tests, I would have disliked feeling confined, but the availability of options helped my attitude. I gave myself the option to take a break and engage in something else I enjoyed because I was feeling overburdened by the amount of material I had to study. This decision enabled me to step back and unwind, which enhanced my viewpoint and assisted me in controlling my stress levels.
d)
A mirror and a ball are two items I'd be curious to put in a bin for Holly to play with to see how she might react. A ball may give Holly an interactive toy that she could play with by herself or with the other chimpanzees, while a mirror could enable her to study her own reflection.
e)
Zookeepers provide Holly with enrichment activities that let her explore her surroundings and make decisions without having to be directly interacted with in order to strike a balance between their need for research and aiding particular animals, like Holly, and respecting Holly's need for "wild space." They also give her adequate room to move about unrestrictedly and engage in social interactions with the other chimpanzees without feeling crowded.

The urinary problem caused by interference with the normal nerve pathways associated with urination known as neurogenic bladder.
Neurogenic bladder is a urinary problem caused by interference with the normal nerve pathways associated with urination. It is a condition wherein the nerves connected to the bladder do not function properly, which leads to difficulty in controlling the bladder and emptying it properly. This can lead to a wide range of symptoms, including difficulty in starting urination, an inability to empty the bladder fully, incontinence, and urinary tract infections.
The primary cause of neurogenic bladder is usually damage to the nerves that control the bladder. This can be due to a variety of conditions, including traumatic brain or spinal cord injuries, multiple sclerosis, Parkinson’s disease, stroke, and diabetes. In some cases, the underlying cause is unknown.
The symptoms of neurogenic bladder are usually the result of an inability to control the flow of urine. This can lead to an overactive bladder, which can cause frequent urges to urinate, even when the bladder is not full. In some cases, the inability to completely empty the bladder can lead to urinary retention, which can cause urinary tract infections. In addition, the condition can also cause incontinence, or the inability to control the flow of urine.

The probability that a child born to two carriers of a recessive disorder allele will have the disorder is 25% can be calculated by the pedigree analysis.
When two carriers of a recessive disorder allele have a child, each parent will pass on one of their two copies of the allele to the child. Since each parent is a carrier, there is a 50% chance that the child will inherit one copy of the allele from each parent. When both copies of the allele are inherited, the child will have the disorder because the disorder only occurs when both copies of the allele are present.
The probability that the child will inherit one copy of the allele from each parent is (1/2) x (1/2) = 1/4 = 25%. Therefore, the probability that a child born to two carriers of a recessive disorder allele will have the disorder is 25%.

As climate changes, which type of reproduction would most likely result in a greater chance of survival for a species? (1) sexual reproduction, with a short reproductive сycle (2) sexual reproduction, with a long reproductive cycle (3) asexual reproduction, with a short reproductive сycle (4) asexual reproduction, with a long reproductive сycle
Sexual reproduction with a short reproductive cycle would probably increase a species' chances of survival as the climate changes. Therefore, option (1) is correct.
The fusing of a haploid female gamete (egg cell) with a haploid male gamete (sperm cell) is known as sexual reproduction. Reproduction requires either one parent (asexual reproduction) or two parents (sexual reproduction).
Asexual reproduction is typically undesirable because the environment is always changing. Sexual reproduction is generally preferred. Asexual reproduction results in organisms that are exact copies of their parents. The process of sexual reproduction can result in the development of new genetic combinations. The variety of phenotypic qualities is also increased by the genetic diversity of organisms.
During meiosis, independent assortment and crossing-over take place, which causes variation. This variation provides organisms the ability to adapt to a changing environment so that they will live and reproduce in the new habitat. In doing so, sexual reproduction would be able to adjust to new environmental challenges. And a shorter reproductive cycle allows it to produce more offspring.

Why do phospholipids tend to spontaneously orient themselves into something resembling a membrane?
Phospholipids tend to spontaneously orient themselves into something resembling a membrane because of their unique chemical structure. Phospholipids are composed of a polar, hydrophilic (water-loving) head and a nonpolar, hydrophobic (water-fearing) tail.
When phospholipids are in an aqueous environment, such as in water or in the cell, the polar heads of the phospholipids interact with the water molecules, while the nonpolar tails are repelled by the water molecules and tend to aggregate together. This creates a barrier that separates the polar heads from the nonpolar tails, which is known as a lipid bilayer.
The hydrophobic effect is the main driving force for the self-assembly of phospholipids into bilayers. The hydrophobic effect is the tendency of nonpolar molecules to aggregate together in order to minimize the number of polar interactions with the surrounding water molecules. This effect drives the phospholipids to align their hydrophobic tails together, creating a barrier that separates the hydrophilic heads from the hydrophobic tails.
