We often observe the evolutionary loss of “useless” organs, such as the eyes in many cave-dwelling animals.
a) Provide two different hypotheses to explain this loss: an adaptive and a nonadaptive hypothesis.
b) How might these hypotheses be tested? Describe what type of data you would need to collect, or potential experiments.
After eating, the level of sugar in the blood rises quickly. Soon after, sugars are quickly transported from the bloodstream to the muscle and liver to be used later as needed (sugar levels return to basal levels). Which characteristic of life is described here?
1. Ability to reproduce
2. Homeostasis
3. Use of energy
3. Ability to evolve
4. Response to environment
Neural nets and genetic algorithms are ways of developing computer softwareusing concepts from biology. Describe these concepts. Take a look at what is going onwith ChatGPT and Midjourney. Select one field in biological science orbiotechnology and examine how you may apply these concepts to the chosen field.What sort of benefits (or problems) might the application of these techniques in this areabring?

- There are many common misconceptions about evolution. Which is TRUE about whale evolution? Early ancestors of whales evolved blowholes because they needed to breathe in the water. Whales are descended from monkeys. Modern whales are perfectly adapted to an aquatic lifestyle. The traits found in whales represent modifications of previous features that were found in their ancestors. Baleen whales evolved their distinctive filter feeding structure by chance.arrow_forwardBelow are three statements - two of which are truths and one is a lie. Which of the following statements is a lie? Select one: a.Some organisms have the function to be responsive only, some have the ability for movement only, but organisms are rarely found to have both functionalities. b.Organisms that are responsive yet are not capable of moving become more prone to dangers, injuries, and eventually lead to its death. c.If an organism has no ability to be responsive to changes in both internal and external environment despite being able to move, then the organism is most likely to be susceptible to danger or even lead to its own death.arrow_forwardTopic: NATURAL SELECTION ACTIVITY Simulate a case of natural selection in a predator-prey situation. STEP 1 Gather your materials. You should have: . 1 fork, 1 knife, 1 spoon, and a length of tape (each will be used toestablish the distinct predator "feeding apparatuses")· 4 cups (each will serve as a distinct predator's "mouth")· 3 types of prey (such as popcorn, macaroni, and kidney beans)· 1 clearly delineated habitat (such as a table, a box, or a roped-off areaof ground). 1 timer that allows for counting by seconds (such as a watch or cellphone) STEP 2 Set up the predators. There is variation in predatory feeding apparatuses in this population. You will choose one of the available predator feeding apparatuses: fork, spoon, knife, or four fingers (with your thumb taped to your hand so that you cannot use it). You will also take a cup, which will represent the predator's mouth. Your goal will be to use your feeding apparatus to collect food and put it inyour mouth. STEP 3 Set up the…arrow_forward
- Can you suggest why, during the evolutionary history of animals, there has been a tendency for maximum body size to increase? Do you think it inevitable that complexity should increase along with body size? Why or why not?arrow_forwardGive detailed Solution with explanation needed (don't give Handwritten answerarrow_forwardNew things to investigate are continually being discovered. For example, modern medical imaging technology allowed biologists to discover structures called the "interstitium" that are now being evaluated as a new organ because of their importance in the physiology of the human body. Although they have different approaches for investigating scientific phenomena, the three types of scientific inquiry work together to help scientists understand phenomena. When something new is discovered, the first types of scientific inquiry will be [ Select ] ["hypothesis-driven experiments", "develop models/theory", "observational descriptive studies"] . Once these initial studies lay a foundation of knowledge about the new discovery, [ Select ] ["hypothesis-driven experiments", "observational descriptive studies", "develop models/theory"] can begin to test various aspects related to it. Finally,…arrow_forward
- Hey can you help me draw a graph showing these results and include a correctly labeled x and y axis. According to the the picture I have attached. Thank you so much your the best :) also side note: the data is trying to test if lizards eat more when it’s cool or hot out and this is how they decided to test it.arrow_forwardThe evolution of jaws was a novel adaption that allowed organisms to process larger particles of food. True or false ?arrow_forwardWhich scientific skill, apparently found only in humans, may have been necessary for the origin of monotheistic religions, as well as the origin of modern theoretical science? the ability to communicate with sign language (using visual signals) the ability to make inferences about infinite quantities (like eternal natural laws) the ability to make and use tools (for food-gathering purposes) the ability to gain knowledge of the environment through perception the ability to communicate orally (using auditory signals)arrow_forward
- The human adaptive mechanism is best described as: a.the ability of the body to help protect itself from fluctuations in energy and nutrient intake. b. the fight or flight response. c.the ability of the body to send cues to the brain on what nutrients and foods should be eaten. d.the ability of the brain to simulate essential nutrient production.arrow_forwardHow can the JHane Goodall Institute research help answer questions about humans?arrow_forwardConsider the following statement. Is it true or false? Why? Please justify your answer explaining the evolutionary process that took place using terms and concepts discussed in our lectures. Individual snakes had to evolve and adjust their mouth size to adapt.arrow_forward
