The migratory eel, Anguilla rostrata, is born and lives the juvenile (immature) part of its life in a freshwater environment, but then migrates thousands of miles through the ocean as an adult in order to breed. These eels are known to regulate their internal water and salt balance. What adaptations would you expect this eel to have in order to transition from fresh water to salt water at these two life stages?
A. The juvenile eels would be better at removing salt from their bodies compared to adults.
B. The adult eels would be better at removing salt from their bodies compared to juveniles.
C. The juvenile eels would spend energy keeping water in their bodies.
D. The adult eels would spend energy keeping salt in their bodies.
Answers
The adult eels would be better at removing salt from their bodies compared to juveniles.
The European eel (Anguilla rostrata) is a catadromic bony fish that spends most of its life in freshwater lakes and rivers before migrating to the Sargasso Sea to spawn.
During seawater adaptation, eels not only change their skin pigmentation from yellow to silvery, but also their physiology to adapt to the new salinity environment.
New metabolic functions should support increased seawater uptake and intestinal absorption. Some structures, such as the digestive system and gills, must adjust body homeostasis to accommodate varying salinities of ingested water.
In addition, before leaving the lagoon, eels must consume more food to increase fat stores and meet their energy needs during the long migration to the Sargasso Sea.
In fact, eels seem to stop feeding until they lay eggs, and the following morphological changes can be seen in their bodies.
Eels arriving at breeding grounds in the Sargasso Sea die after spawning as a result of extreme exercise.
This still-enigmatic biological life cycle has prevented breeding in captivity. In fact, its biological properties have intrigued researchers for centuries.

The graphs above show a change in distribution of beak phenotypes X, Y, and Z over 10 generations. Notice that Beak X completely disappears from the population by Generation 5, but reappears by Generation 10. Could this occur in nature? How?
Answers
A, Yes, the alleles for Beak X could remain in the population as a recessive gene.
What is the rationale behind it?Recessive genes. The alleles for beak X could remain in the population as recessive genes. This means that birds with beak X would still be able to pass on the genes for beak X to their offspring, even if they themselves did not have beak X. If two birds with the recessive gene for beak X mated, their offspring would have a 25% chance of having beak X.
Mutation. The birds could mutate their beaks in response to a change in the environment. This could lead to the appearance of beak X, even if the gene for beak X was not present in the population before.
Random chance. Genetic mutation is so frequent that it is possible for beak X to reappear randomly by generation 10. This is especially likely if the environment is changing and there is a selective advantage for birds with beak X.
In conclusion, it is possible for beak X to reappear after 5 generations in nature. This could happen through the inheritance of recessive genes, mutation, or random chance.

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.

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.”
Answers
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.

Which of the following is a correct sequence of events in cellular respiration?
Answers
The correct sequence of events in cellular respiration is option a: glycolysis, citric acid cycle, electron transport chain.
During cellular respiration, glucose is broken down to produce energy in the form of ATP. The process starts with glycolysis, which occurs in the cytoplasm and involves the breakdown of glucose into pyruvate molecules. Glycolysis generates a small amount of ATP and NADH.
The pyruvate molecules produced in glycolysis enter the mitochondria, where the citric acid cycle, also known as the Krebs cycle, takes place. In this cycle, the pyruvate is further broken down, releasing carbon dioxide and generating NADH and FADH2 as electron carriers. The citric acid cycle also produces a small amount of ATP.
The electron carriers NADH and FADH2 then participate in the electron transport chain, which is located in the inner membrane of the mitochondria. In the electron transport chain, the electrons from NADH and FADH2 are transferred through a series of protein complexes, creating a flow of electrons that drives the synthesis of ATP. This process is known as oxidative phosphorylation.
Therefore, the correct sequence of events in cellular respiration is glycolysis, citric acid cycle, and electron transport chain, as stated in option a.

Answers
Answer:
The correct answer is ''arises from the greater splanchnic nerve''
Explanation:
The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.

What is diversifying selection?
Answers
Diversifying selection can also be called Disruptive selection. It involves changes in a population that leads to extreme values for a trait. This means that, instead of having several small differencies in a characteristic amongst the organisms, the organisms tends to have only two "options" of how this characteristic is available. A simple example is that, instead of several different colors of flowers in different nuances of yellow and green, including colors that are intermediate between yellow and green, we will find only two colors: a strong yellow and a strong green. Individuals can develop a tendency of developing one of the two extreme ways of expressing a trait, against the intermediate ones. It is part of natural selection, it is not artificial selection, and it favours two variants, instead of many variants. So you will have two variants of the same trait appearing, and they tend to be extremely opposed to each other.

A population of 500 beetles is expected to grow at a rate of 70% per week. Which number is the best prediction of the population after 15 weeks?.
Answers
The best prediction of the population after 15 weeks will be 1,431,212 beetles.
What is the population growth ?The average annual rate of change in population size for a given country, region, or region over a given period. It represents the annual growth rate of the population as a percentage of the total population for that year, usually multiplied by 100.
Population growth is the increase in the number of people within a population or dispersed group.
To calculate total population:
The total number of beetles = 500
The rate of population increase = 70% per week
So, 70% of 500= 70/100 × 500
= 35000/100
= 350 per week.
This means there will be additional 350 beetles every week,
That is = 500 + 350 = 850 beetles
850/500 = 1.7 times the initial population
Therefore in 15 weeks = 500× 1.7¹⁵
= 500 × 2862.4231
= 1,431,212
