Answer:
Two different kinds of flasks were used - regular and swan-necked
Explanation:
In his experimental design, Louis Pasteur used tow flasks. One of the flask was regular flask and the other was swan necked. He used these flasks to boil a meat broth. In the swan neck flask, air could enter but microorganisms could not. As a result, there was no grown seen in that flask. In the regular flask, microorganisms could enter and they spoiled the meat. Hence, the two different types of flasks were his experimental design.
The answer is insects.

Q5.
<span>The
answer is A. In thermodynamics, the first
law of conservation states that energy can never be destroyed or created but
can only be transformed from one form to another. Therefore part of the
electric energy was converted to light energy while the other dissipated as
heat. However, the summation of the energy
of these tow outputs in joules remains
the same as initial electric energy.

Q6
<span>The answer is B. This is because
the water in the dam is used to turn turbines hence this form of energy is mechanical energy. As the turbines turn, they
turn electromagnets that convert the mechanical energy into electrical energy</span>
Answer:
I am too lazy to do this, but I am assuming you were supposed to do this in class. I will give you ideas.
Why is soil important? Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites.
What is soil erosion? Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.
what human activities are responsible for soil erosion happening at advance rates? Ploughing, unsuitable agricultural practices, combined with deforestation and overgrazing, are the main causes of human-induced soil erosion
What are some effects on soil loss? The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
What can be done to prevent soil erosion? Maintaining a healthy, perennial plant cover.
Mulching.
Planting a cover crop – such as winter rye in vegetable gardens. ...
Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.
