To identify the organs found in the illustrations of both humans and frogs based on the options provided, let's analyze the choices:
-
Liver, lungs, pancreas, stomach, intestines, spleen, gallbladder, urinary bladder – These organs are commonly found in both humans and frogs.
-
Brain, lymph nodes, lungs, stomach, gallbladder, muscles, kidneys, veins – While some of these organs are present in both species, lymph nodes are specific to humans as part of the immune system.
-
Fat bodies, skeleton, kidneys, veins, stomach, intestines, muscles, pharynx, larynx – Fat bodies are specific to frogs, while the pharynx and larynx are more pronounced in amphibians.
Given that you want to identify organs found in both humans and frogs, the first option is the most comprehensive as it lists the organs that are present in both species.
Correct Response:
Liver, lungs, pancreas, stomach, intestines, spleen, gallbladder, urinary bladder.
Which body system is most represented in the picture of the frog on the title page/page 1?(1 point)
Responses
Nervous system
Nervous system
Excretory system
Excretory system
Digestive system
To determine which body system is most represented in the picture of the frog, we would typically look at the organs and structures that are illustrated.
- Nervous System: This would include the brain and nerves.
- Excretory System: This would include kidneys and structures related to waste removal.
- Digestive System: This includes organs such as the stomach, intestines, and liver.
If the image prominently features the digestive organs of the frog, such as the stomach and intestines, then the most represented body system would be the Digestive System.
If it shows mainly the kidneys or bladder, then the Excretory System would be more represented.
In general, frogs are often examined in terms of their digestive system, as they are commonly studied in educational settings through dissections that highlight these organs.
Without seeing the specific illustration, but given the common focus in educational texts, the Digestive System is likely the correct answer.
Correct Response:
Digestive system.
Which statement best explains the importance of both mechanical and chemical digestion in humans and frogs?(1 point)
Responses
Mechanical digestion only occurs in humans, while chemical digestion only occurs in frogs.
Mechanical digestion only occurs in humans, while chemical digestion only occurs in frogs.
Mechanical digestion breaks down food physically, while chemical digestion uses enzymes to break down food into nutrients in both organisms.
Mechanical digestion breaks down food physically, while chemical digestion uses enzymes to break down food into nutrients in both organisms.
Both mechanical and chemical digestion are not necessary in humans and frogs as they have different digestive needs.
Both mechanical and chemical digestion are not necessary in humans and frogs as they have different digestive needs.
Mechanical digestion uses enzymes to break down food into smaller pieces, and chemical digestion breaks down food physically.

The statement that best explains the importance of both mechanical and chemical digestion in humans and frogs is:
Mechanical digestion breaks down food physically, while chemical digestion uses enzymes to break down food into nutrients in both organisms.
This statement accurately describes the roles of both types of digestion, highlighting that mechanical digestion involves the physical breakdown of food (such as chewing or grinding) and that chemical digestion involves enzymatic processes that convert food into absorbable nutrients. It is relevant for both humans and frogs.
Correct Response:
Mechanical digestion breaks down food physically, while chemical digestion uses enzymes to break down food into nutrients in both organisms.
How does the structure of the digestive tract, beginning at the mouth and ending at the anus, facilitate efficient digestion in both humans and frogs?(1 point)
Responses
It allows for a one-way flow of food, preventing waste from being reabsorbed and ensuring complete digestion and elimination.
It allows for a one-way flow of food, preventing waste from being reabsorbed and ensuring complete digestion and elimination.
It enables food to be digested only chemically, without the need for mechanical breakdown.
It enables food to be digested only chemically, without the need for mechanical breakdown.
This structure is unique to humans, while frogs have a different digestive tract arrangement.

The statement that best explains how the structure of the digestive tract facilitates efficient digestion in both humans and frogs is:
It allows for a one-way flow of food, preventing waste from being reabsorbed and ensuring complete digestion and elimination.
This statement correctly identifies the importance of having a one-way digestive tract, which helps in the efficient processing of food, better absorption of nutrients, and the proper elimination of waste without the risk of reabsorption. Both humans and frogs have a digestive system structured this way.
Correct Response:
It allows for a one-way flow of food, preventing waste from being reabsorbed and ensuring complete digestion and elimination.
Which statement accurately describes a major difference between human and frog respiration?(1 point)
Responses
Both humans and frogs use their diaphragm muscles to breathe.
Both humans and frogs use their diaphragm muscles to breathe.
Frogs use their mouth muscles and skin sacs to breathe, while humans use diaphragm muscles.
Frogs use their mouth muscles and skin sacs to breathe, while humans use diaphragm muscles.
Frogs yawn to take in oxygen through their mouths, while humans only breathe through their noses.
Frogs yawn to take in oxygen through their mouths, while humans only breathe through their noses.
Humans and frogs both can breathe through their skin.
The statement that accurately describes a major difference between human and frog respiration is:
Frogs use their mouth muscles and skin sacs to breathe, while humans use diaphragm muscles.
This statement highlights the different mechanisms of respiration between the two species. Frogs utilize their mouth and skin for gas exchange, along with a form of buccal breathing, while humans primarily rely on diaphragm contractions for breathing.
Correct Response:
Frogs use their mouth muscles and skin sacs to breathe, while humans use diaphragm muscles.
what is cutaneous respiration in frogs?(1 point)
Responses
Breathing through the mouth and nose at the same time.
Breathing through the mouth and nose at the same time.
Breathing through the skin underwater.
Breathing through the skin underwater.
Breathing through inflating their throat sacs.
Breathing through inflating their throat sacs.
Breathing using diaphragm muscles like humans.
The correct definition of cutaneous respiration in frogs is:
Breathing through the skin underwater.
Cutaneous respiration refers to the process by which frogs and some other amphibians exchange gases through their skin, allowing them to take in oxygen and release carbon dioxide, particularly when they are submerged in water.
Correct Response:
Breathing through the skin underwater.
