A. Orthoptera (Crickets and grasshoppers
- B.
B. Thysanura (Firebratsand silverfish)
- C.
C. Blattodea(cockroaches)
- D.
D. Thysanoptera (thrips)
Correct Answer
D. D. Thysanoptera (thrips)Explanation
Thysanoptera, also known as thrips, is the correct answer because some species within this insect order are known to transmit plant diseases. Thrips are small, slender insects that feed on the sap of plants, and during this feeding process, they can introduce viruses or other pathogens into the plant, causing diseases. Other insect orders mentioned in the options, such as Orthoptera (crickets and grasshoppers), Thysanura (firebrats and silverfish), and Blattodea (cockroaches), are not typically associated with transmitting plant diseases.Rate this question:

D. All of the above
Correct Answer
C. C. Has backboneExplanation
Vertebrates are characterized by having a backbone, which is a bony or cartilaginous structure that runs along the length of their body. This backbone, also known as the vertebral column or spine, provides support and protection for the spinal cord and allows for movement and flexibility. Vertebrates include animals such as mammals, birds, reptiles, amphibians, and fish. The other options, such as never laying eggs and having fur, are not features that characterize all vertebrates, as there are some vertebrates that do not lay eggs (e.g., live-bearing mammals) and some that do not have fur (e.g., reptiles and fish).Rate this question:

Which part of a plan do nematodes Most. Commonly attack?
- A.
A. Fruit
- B.
B. Roots in other underground plant parts
- C.
C. Germinating seeds
- D.
D. Flowers
Correct Answer
B. B. Roots in other underground plant partsExplanation
Nematodes commonly attack the roots in other underground plant parts. Nematodes are microscopic worms that feed on plant roots, causing damage and stunting plant growth. They are a major pest in agriculture and can cause significant crop losses. By attacking the roots, nematodes disrupt the plant's ability to take up water and nutrients, leading to poor plant health and reduced yields. Controlling nematode populations is important for maintaining healthy plants and maximizing crop productivity.Rate this question:

Which of the following pests Would cause leaf Stippling .?
- A.
A.Fungus disease
- B.
B. Beetle larvae
- C.
C. Mites
- D.
D.caterpillars
Correct Answer
C. C. MitesExplanation
Mites would cause leaf stippling. Stippling refers to the tiny, discolored spots or dots that appear on the leaves of plants. Mites are tiny arachnids that feed on the sap of plants, causing damage to the leaves. As they feed, they puncture the plant cells, resulting in stippling. This is different from the damage caused by fungus diseases, beetle larvae, or caterpillars, which typically cause larger areas of discoloration or holes in the leaves.Rate this question:

C. Egg, larva,nymph,adult
- D.
D. Egg,larva,pupa,adult
Correct Answer
D. D. Egg,larva,pupa,adultExplanation
Insects that undergo complete metamorphosis go through four distinct stages in their life cycle. These stages include the egg stage, larva stage, pupa stage, and adult stage. The larva stage is characterized by active feeding and growth, while the pupa stage is a period of transformation where the insect undergoes significant changes and eventually emerges as an adult. Therefore, option D, which includes all four stages in the correct order, is the correct answer.Rate this question:

Powdery mildew on plants is caused by ?
- A.
A. Insect feeding damage
- B.
B.Fungus
- C.
C. Cultural practices
- D.
D. High temperatures
Correct Answer
B. B.FungusExplanation
Powdery mildew on plants is caused by a fungus. Powdery mildew is a common fungal disease that affects a wide range of plants. It appears as a white or gray powdery growth on the leaves, stems, and sometimes flowers of infected plants. The fungus thrives in warm and humid conditions, and it spreads through spores that are easily carried by wind or water. Fungicides and cultural practices such as proper spacing and good air circulation can help prevent and control powdery mildew. Insect feeding damage, cultural practices, and high temperatures are not the primary causes of powdery mildew.Rate this question:

An abiotic disorder of a plant can be caused by ?
- A.
A.insects or mites
- B.
B. Fungal organisms
- C.
C. Irrigation problems
Correct Answer
C. C. Irrigation problemsExplanation
Abiotic disorders in plants refer to problems that are caused by non-living factors, such as environmental conditions or human activities. Irrigation problems can lead to abiotic disorders in plants because improper watering, either too much or too little, can cause stress to the plant. Overwatering can lead to root rot and lack of oxygen, while underwatering can cause wilting and nutrient deficiencies. Therefore, irrigation problems can directly affect the health and growth of plants, making option C the correct answer.Rate this question:
