Humus mixture prepared by filling the horn of a cow with cow manure and burying it in the ground (_______ctm below the surface) in the autumn.

50-75
40–60
75-90
25-50

Correct Answer

A. 40–60

Explanation

The humus mixture is prepared by filling the horn of a cow with cow manure and burying it in the ground. The depth at which it is buried is between 40 and 60 centimeters below the surface.

___________________is a broad-based approach that integrates practices for economic control of pests.

General pest control (GPC)
Integrated fungal control (IFC)
Integrated pest control (IPC)
None of the above

Correct Answer

A. Integrated pest control (IPC)

Explanation

Integrated pest control (IPC) is a broad-based approach that integrates practices for economic control of pests. This approach involves combining various pest control methods such as biological control, cultural control, physical control, and chemical control in a coordinated and sustainable manner. By using a combination of these methods, IPC aims to minimize the reliance on pesticides and reduce the negative impact on the environment while effectively managing pest populations. GPC and IFC are not broad-based approaches like IPC, and "None of the above" is not the correct answer as IPC fits the description given in the question.

Forrest Innovations is investigating RNAi as a solution to citrus greening disease that in 2014.

Banana
Grapes
Citrus
Apple

Correct Answer

A. Citrus

Explanation

The correct answer is "Citrus" because the question mentions that Forrest Innovations is investigating RNAi as a solution to citrus greening disease. Citrus greening disease specifically affects citrus plants, so it makes sense that the company would focus on finding a solution for this particular crop.

______________agents are living organisms; their success is affected by several factors like temperature, pH, moisture, UV, soil conditions, and other microbial competitors present in the environment.

Humas
Biopesticides
Chemical pesticides
Bioinsecticide

Correct Answer

A. Biopesticides

Explanation

Living organisms, such as agents, are affected by various factors like temperature, pH, moisture, UV, soil conditions, and microbial competitors in the environment. Biopesticides, which are derived from natural materials like plants, animals, bacteria, and certain minerals, are a type of pesticide that utilizes living organisms to control pests. Therefore, biopesticides are the correct answer as they align with the concept of living organisms being affected by environmental factors and being used for pest control.

____________are stuffed into small intestines from cattle buried in humus-rich earth in the autumn and retrieved in the spring.

Oak bark (Quercus robur)
Horsetail (Equisetum)
Chamomile blossoms (Matricaria recutita)
Stinging nettle (Urtica dioica)

Correct Answer

A. Chamomile blossoms (Matricaria recutita)

________________ has usually no known function in photosynthesis, growth or other basic aspects of plant physiology.

Humas
Biopesticides
Chemical pesticides
DDT

Correct Answer

A. Biopesticides

Explanation

Biopesticides usually have no known function in photosynthesis, growth, or other basic aspects of plant physiology. This means that they do not directly contribute to the plant's metabolic processes or overall development. In contrast, humas, chemical pesticides, and DDT may have some impact on plant physiology, either by providing nutrients (humas) or by affecting the plant's growth or metabolism (chemical pesticides and DDT). Therefore, the correct answer is biopesticides.

_________are cold-blooded, their physical development is dependent on area temperatures.

Fungus
Insects
Bacteria
Humans

Correct Answer

A. Insects

Explanation

Insects are cold-blooded, meaning their body temperature is determined by the surrounding environment. This is different from warm-blooded animals like humans, who can regulate their body temperature internally. Therefore, the physical development of insects is dependent on the temperature of the area they inhabit.

Germany accounts for _____ of the global total; the remainder average 1750 ha per country.

75%
23%
45%
60%

Correct Answer

A. 45%

Explanation

Germany accounts for 45% of the global total, while the remainder of the countries average 1750 ha each. This means that Germany has a significant share of the global total, but it is not the majority. The fact that the remainder average 1750 ha per country suggests that there are many countries with smaller land areas compared to Germany.
