The mouthparts of a grasshopper are adapted for
sucking
chewing
grinding
absorption
Correct answer is B
Grasshoppers are herbivorous insects that primarily feed on plant material. Their mouthparts are well adapted for chewing, allowing them to consume various parts of plants, such as leaves, stems, and flowers.The mouthparts of a grasshopper consist of several structures that work together during feeding:
Mandibles, Maxillae and Labium and Labrum.
community
biosphere
niche
population
Correct answer is A
A community in ecology refers to a group of different species that inhabit the same geographic area and interact with one another. These species share a common habitat and are interconnected through various ecological relationships. In a community, the interactions between different species can be complex and can include competition, predation, mutualism, commensalism, and parasitism.
The diagram below is an illustration of a mango leaf drawn by a student in a Biology test. The student failed the test. Study it and answer the question.
which features of the diagram would have earned the student more marks if shown
colour and size
spelling the label and length of midrib
habitat and agricultural qualities of leaf
title and margin
Correct answer is D
No explanation has been provided for this answer.
The diagram below is an illustration of a mango leaf drawn by a student in a Biology test. The student failed the test. Study it and answer the question.
The likely reason why the student failed the test was that the
labels were wrong and the guidelines were not touching the structures
net venation shown were few, rough, not properly drawn and wrongly placed
leaf venation should have been parallel and the midrib should be thicker
leaf was too tapered at the apex, the leaf stalk was too short and the shape of leaf was wrong
Correct answer is A
The likely reason why the student failed the test was that the labels were wrong and the guidelines were not touching the structures
The structure that its action could result in choking when talking and eating at the same time is
oesophagus
epiglottis
oesophagus
liver
Correct answer is B
The structure that could result in choking when talking and eating at the same time is the epiglottis.
The epiglottis is a flap-like structure located at the base of the tongue, near the entrance of the windpipe (trachea). Its primary function is to prevent food and liquids from entering the trachea and lungs during swallowing. When you swallow, the epiglottis covers the opening of the trachea, directing food and liquids into the esophagus, which leads to the stomach. This prevents choking and aspiration of food into the respiratory system.
