Algae growth and oxygen depletion in lakes and stream, and methemoglobinemia, caused by too much nitrate-nitrogen in drinking water.
Answer:
The correct answer is: simple squamous epithelium.
Explanation:
The epithelium is one of the four basic tissues found in the body, along with the connective tissue, the muscle tissue, and the nervous tissue.
Epithelial tissue is commonly found surrounding surfaces such as the skin, and also making up the inner lining of hollow organs such as the ones that form the gastrointestinal tract.
<u>The number of layers and the shape of the cells in the epithelium have a direct correlation in the function of the tissue.</u> Functions can vary a lot from organ to organ, from absorption to protection and everything in between.
<u>A</u><u> simple squamous epithelium</u><u> is composed of a single layer of flat cells, which makes it permeable to liquids and small molecules, an important feature in organs where filtration or diffusion is needed; for example: capillaries and alveoli</u>.
This question seems to be incomplete because the experiment is not described but it is possible to answer it.
The correct answer is B. Redi disproved spontaneous generation.
Explanation:
Francesco Redi was an important scientist during the 17th century known for his experiments about maggots in rotten meat. This is because during Redi's time it was believed rotten meat was the origin of maggots because maggots seemed to emerge from this. Additionally, this perception was related to the spontaneous generation or the idea life can emerge from non-living materials. The results of this experiment show the idea about spontaneous generation was not true in the case of meat and maggots because maggots were simply the result of eggs flies laid on rotten meat. This means this experiment disproved spontaneous generation.
Examples of abiotic factors are water, air, soil, sunlight, and minerals.Biotic factors are living or once-living organisms in the ecosystem.
Biotic describes a living component of an ecosystem; for example organisms, such as plants and animals.
Examples Water, light, wind, soil, humidity, minerals, gases.
