C:Recycling of water from dissolved food back into the body
D: Reaction of saliva, stomach acid, bile, and pancreatic juices with food
Answers
The example that includes only chemical changes that occur in the digestive process is the reaction of saliva, stomach acid, bile, and pancreatic juices with food. Option D.
What are chemical changes?Chemical changes refer to changes to the chemical properties of substances. In biological reactions, these substances are referred to as reactants.
Chemical changes are different from physical changes. In physical changes, only the physical properties of substances are altered while their chemical properties remain intact.
When a substance changes chemically, its physical properties most often change along. However, this is not in all cases.
Thus, looking at the examples given, their classification into either physical or chemical changes is as follows:
Absorption of nutrients by villi in the small intestines: physical changeChewing and swallowing food: physical changeRecycling of water from dissolved food back into the body: physical changeThe reaction of saliva, stomach acid, bile, and pancreatic juices with food.When saliva, stomach acid, bile, and pancreatic juices react with food, the chemical properties of food change because the enzymes convert different components of food from one form to another as part of the process of digestion.

Carlton and Vanessa are lab partners in their biology class. One of their labs was to run the smell test experiment on each other.
When performing the smell test, Vanessa was quite good at noticing a difference between the various intensities of vanilla and also
the various intensities of evergreen. Although Carlton could distinguish what the vanilla and evergreen smells were, he couldn't tell
there was a difference in the intensities in the vanilla or the evergreen. Based on the information presented in this scenario, which
of the following is true?
Vanessa has a more sensitive difference threshold than Carlton.
Carlton has an impaired absolute threshold.
Vanessa has a better absolute threshold than Carlton.
Carlton has the superior performance with respect to the difference threshold.
Vanessa has an impaired absolute threshold.
Answers
Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.
Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.
Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.
Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.
The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.
Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.
This shows that Carlton has an impaired absolute threshold.
He could not detect the smallest quantity of a stimulus to differentiate between the smells.
Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.
This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.
Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

Answers
Answer:

Explanation:
a) Two factors they need to keep the same in their investigation are the type of plant they are using and the amount of water and light they give each plant.
b) The factor they change is the amount of water and light they give to each plant.
To get their results, they measure the growth of each plant over a set period of time. They may also measure other factors such as the number of leaves, the height of the plant, or the color of the leaves to determine the overall health of the plant.
a) In their investigation, the students need to keep two factors the same:
1. Temperature: They must maintain a constant temperature of 25°C throughout the experiment.
2. Control substances: They need to keep the substances used in the control situation the same.
b) The factor they change is:
The students change the conditions related to the pH of the reaction mixture, the amount of yeast added, and the type of sugar used.
a) In their investigation, the students need to keep two factors the same:
1. Temperature: They must maintain a constant temperature of 25°C throughout the experiment. This ensures that any changes in the rate of fermentation are solely attributed to the variables they are testing.
2. Control substances: They need to keep the substances used in the control situation the same. This includes using 25 ml of buffer pH 7, 2 grams of sucrose, and 2 grams of yeast. Keeping these constant allows for a baseline comparison against the experimental conditions.
b) The factor they change is:
The variable being tested: The students change the conditions related to the pH of the reaction mixture, the amount of yeast added, and the type of sugar used. These variables are altered to observe their effect on the rate of fermentation.
To obtain their results, the students measure the pressure generated during the fermentation process. They use a Vernier Equipment Pressure sensor connected to a LabPro interface to record the pressure values over time.
By collecting and analyzing the pressure data, they can assess the rate of fermentation under different experimental conditions. The pressure readings indicate the gas produced as a byproduct of fermentation, providing a quantitative measure of the fermentation rate.
This allows the students to determine the optimal conditions for the new fermentation process to be used at the local bakery.

What does this say about the number of different kinds of proteins available in nature
Answers
Answer:
Proteins are very varied, and the number of junctions and the arrangement in which these junctions are found depends on this.
In addition to taking into account the amount of amino acids.
Explanation:
Proteins in nature are found in great variety, this is due not only to the amount of amino acids present, but the multiple combination options between these amino acids, we must not ignore the unions, that is why some proteins are more complex what others.
Proteins have different unions and this makes it have different coformations, there are primary, secondary, tertiary and quaternary unions, if the protein has all these unions it is considered complex, whereas if it has the simplest it is considered a simple protein.
What would happen to this ecosystem if another apex predator, such as a killer whale, was introduced?
Answers
The introduction of an apex predator, such as a killer whale to an ecosystem can have significant impacts on the existing food web and ecosystem dynamics.
Thus, the presence of a new apex predator, such as a killer whale increases the competition between the existing apex predator and the newly introduced predator for food resources, such as seals and sea lions.
The introduction of a new apex predator can also affect the behavior of the existing species. For example, the seals can change their behavior to protect themselves from predation by the killer whale by changing their movement patterns.
The introduction of a new apex predator like a killer whale to this ecosystem require careful monitoring and management to minimize the negative impacts on the ecosystem.
