Grasshopper Laboratory Practical (Ab) (Cb)
Welcome to the biology electronic frontier classroom of the 21st century. The grasshopper will be used to demonstrate some of the details of insect structure and function. As you have read from online resources and your textbook. The diversity of the insect world is so great that no typical insect exists. Please check under the Advanced Biology tab and click "experiments" to review linked activities to grasshoppers.
When a "fill-in" type question presents itself in this test or others created by the educational director for the web site "Mitchell's Cosmic Read moreAdventure". Please enter your answer(s) using all lower case letters. Please follow the directions at the question site.
I wish you very good luck on this pretest laboratory practical on the anatomy of the Romalea spp.

Grasshoppers belong to the family Acrididae.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement "Grasshoppers belong to the family Acrididae" is true. Acrididae is a family of insects that includes grasshoppers, locusts, and their close relatives. These insects are characterized by their long hind legs adapted for jumping and their ability to produce sound by rubbing their wings or legs together. Grasshoppers are known for their herbivorous diet and are found in various habitats worldwide. Therefore, it is correct to say that grasshoppers belong to the family Acrididae.Rate this question:

Correct Answer
C. Abdomen, Head, ThoraxExplanation
The eastern lubber grasshopper has three main body sections: the abdomen, head, and thorax. The abdomen is the posterior part of the body, housing the digestive and reproductive organs. The head contains the sensory organs, including the eyes and mouthparts. The thorax is the middle section of the body, which contains the legs and wings used for locomotion.Rate this question:

Grasshoppers carry out respiration small lateral openings on the body called_____.
- A.
Coxa
- B.
Nerve Cord
- C.
Lungs
- D.
Spiracles
Correct Answer
D. SpiraclesExplanation
Grasshoppers carry out respiration through small lateral openings on their body called spiracles. These spiracles are connected to a network of tubes called tracheae, which deliver oxygen directly to the cells. This adaptation allows grasshoppers to efficiently exchange gases with their environment and obtain the oxygen they need for respiration. The other options, coxa, nerve cord, and lungs, are not involved in the respiratory system of grasshoppers.Rate this question:

Eastern lubber grasshopppers have excretory organs called malpighian segments.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Eastern lubber grasshoppers do not have excretory organs called malpighian segments. Malpighian segments are actually found in insects such as beetles, flies, and mosquitoes. Eastern lubber grasshoppers have a different excretory system known as the tubular excretory system. Therefore, the correct answer is False.Rate this question:

Eastern lubber grasshoppers use the _____ _____ to break down food using enzymes.
- A.
Auditory membrane
- B.
Flight wing
- C.
Gastric caeca
- D.
Salivary glands
Correct Answer
C. Gastric caecaExplanation
Eastern lubber grasshoppers use the gastric caeca to break down food using enzymes. Gastric caeca are specialized pouches located in the digestive system of insects, including grasshoppers. They secrete enzymes that help in the digestion and breakdown of food. These enzymes break down complex molecules into simpler forms that can be absorbed by the grasshopper's body for nutrition and energy. The gastric caeca play a crucial role in the grasshopper's digestive process.Rate this question:

The eastern lubber grasshopper has the thorax divided into three sections. Please identify the segments from superior to inferior body directions.
- A.
Metathorax, Prothorax, Mesothorax
- B.
Prothorax, metathorax, Mesothorax
- C.
Head, Metathorax, Post-thorax
- D.
Prothorax, Mesothorax, Metathorax
Correct Answer
D. Prothorax, Mesothorax, MetathoraxExplanation
The correct answer is Prothorax, Mesothorax, Metathorax. The explanation is that the question is asking for the segments of the eastern lubber grasshopper's thorax from superior to inferior direction. The superior direction refers to the top or upper part of the body, while the inferior direction refers to the bottom or lower part of the body. Therefore, the correct order is Prothorax (superior), Mesothorax (middle), and Metathorax (inferior).Rate this question:

What structure would you find the pulvillus on the eastern lubber grasshopper?
- A.
Compound eyes
- B.
Hind Leg Tibia
- C.
Labium
- D.
Mandible
Correct Answer
B. Hind Leg TibiaExplanation
The pulvillus is a structure found on the hind leg tibia of the eastern lubber grasshopper. This structure is important for the grasshopper's ability to grip surfaces and navigate its environment. The compound eyes, labium, and mandible are all different structures found in grasshoppers, but they do not have the pulvillus.Rate this question:

The ocellus is a large compound eye found on the eastern lubber grasshopper.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because the ocellus is not a compound eye found on the eastern lubber grasshopper. The ocellus is actually a simple eye found in some insects, including grasshoppers, which is used to detect light and dark. Compound eyes, on the other hand, are made up of multiple individual lenses and are found in many insects, including grasshoppers. Therefore, the ocellus is not a compound eye and the statement is false.Rate this question:

- A.
Cercus
- B.
Epiproct
- C.
Ovary
- D.
Maxillary Pulp
- E.
Ovipositor
Correct Answer
D. Maxillary PulpExplanation
The structure that does not belong to the reproductive system of the eastern lubber grasshopper is the Maxillary Pulp. The other structures listed, such as the Cercus, Epiproct, Ovary, and Ovipositor, are all directly involved in the reproductive processes of the grasshopper. The Maxillary Pulp, on the other hand, is not a part of the reproductive system but rather a structure found in the mouthparts of insects. It is responsible for aiding in the ingestion and digestion of food.Rate this question:

Intestine
- E.
Mandible
- F.
Mentum
Correct Answer
D. IntestineExplanation
The question asks about the structure that does not belong to the mouth parts of the eastern lubber grasshopper. The structures mentioned are clypen, galea, ligula, intestine, mandible, and mentum. The clypen, galea, ligula, mandible, and mentum are all mouth parts that are commonly found in grasshoppers. However, the intestine is not a mouth part but rather a part of the digestive system. Therefore, the correct answer is intestine.Rate this question:

What is the two types of wings found on grasshoppers in the Order "Orthoptera"? (Please check 2 answers to receive full credit for this question.)
- A.
Galea wing
- B.
Flight wing
- C.
Lacina wing
- D.
Protective wing
- E.
Labrum wing
- F.
Tochanter wing
Correct Answer(s)
B. Flight wing
D. Protective wingExplanation
Grasshoppers in the Order "Orthoptera" have two types of wings: flight wings and protective wings. Flight wings allow grasshoppers to fly and are necessary for their mobility and dispersal. Protective wings, also known as tegmina, are tough and leathery and serve to protect the delicate flight wings when they are not in use. These protective wings provide camouflage and help to shield the grasshopper's body from predators and environmental elements.Rate this question:
