Answer:
Spontaneous generation, the hypothetical process by which living organisms develop from nonliving matter.
Explanation:
In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. One jar was left open; the other was covered with a cloth. Days later, the open jar contained maggots, whereas the covered jar contained no maggots. He did note that maggots were found on the exterior surface of the cloth that covered the jar. Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.
Answer: prophase
Explanation:
Each chromosome becomes condensed (pact together) which makes it more visible to see it
<span>The tympanic membrane or eardrum is a membrane in the ear that vibrates when hit by sound waves.It is tightly stretched and separates the ear canal from the middle ear. When sound waves hit the tympanic membrane, it vibrates. these vibrations are then passed to the middle ear, which consist of the ossicles or ear bones. </span>
Answer:
1. Bioremediation
2. Biological Control
Explanation:
Bioremediation is the process in which the environmental condition of the contaminated media such as land, water and soil is altered with the growth of microorganisms and plants to treat the contamination.
So, biologist used the method of bioremediation, by using specific plants that will detoxify the area contaminated with heavy-metal pollution.
Biological control is the method in which pests such as mites, weeds, insects and plant diseases are controlled by using other organisms.
So, here also biologist used biological control method and introduced species of fish into bodies of water to control mosquitoes development.
Hence, the correct options for the blanks are 1. Bioremediation and 2 . Biological Control.
