the growth of each plant
the amount of sunlight provided to each plant
the amount of soil provided to each plant
Answer:
The growth of each plant
Explanation:
I'm not sure what the experiment was, but the growth of the plant is dependent on the amount of water, sunlight, and soil, and is therefore the dependent variable.
b. economic consequences
c. development hindrances
d. all of the above
Answer: d. all of the above
Fossil fuels such as coal, oil and gas are beneficial sources of energy used by the human society. Fossil fuels are non- renewable resources, which are produced after millions of years of geological and biological activity taking place inside the earth crust. Human society is mainly dependent upon the fossil fuels to maintain it's energy needs.
There are some negative consequences associated with fossil fuels:
Environmental consequences: Fossil fuels are used for generation of energy in the power plants and by the automobiles. These sources releases partially and completely combusted products which includes the poisonous gases causing air and water pollution.
Economic consequences: Fossil fuel use is related with economic crisis because fossil fuels are non- renewable resources, which cannot be replenished once used. They are expensive and many commercial energy generation processes are dependent on them such as electricity, transportation and others.
Development hindrances: Large dependence on fossil fuels creating an hindrance on development process. As, there are very few findings which are resulted which could replace the fossil fuels, these finding can be beneficial for the environmental and economic point of view.
Answer:
Nick observes thickening and discoloration of the nail of the index finger. Nick is most likely suffering from an onychomycosis infection.
Explanation:
Onychomycosis is a chronic and progressive infection of the nails caused by fungi. In most cases it is produced by dermatophytes, and less frequently by yeasts and molds. It is the most frequent nail disease.
Onychomycosis can affect the appearance, thickness and color abnormally, both in the nails of the hands and the feet, although the nail of the big toe is the most frequently affected.
B- Plant Cells need chloroplasts to make food because most plants cannot move to get there food on their own
C- I dont know
D- Plants cells need Chloroplasts to move materials in and out of the cell because most plants cells do not Contain a Cell Membrane
Answer: D
Explanation: Because The Chloroplast is the Gate to move waste out of the cell and nutrients into the cell. Most plants do not contain a cell membrane.
Animal cells have a chloroplast and plant cells don't have a chloroplast because plant cells uses the chloroplast to produce energy from the chloroplast. So, option B, i.e., plant cells need chloroplast to make food because plant cannot move to get their food on their own, is correct.
The plants produce energy or their food with the help of a process known as photosynthesis.
The chloroplast is a green colored cell organelle which is responsible for carrying out photosynthesis.
In the photosynthesis, the light energy from sun is converted into chemical energy which is utilized as food by the plant.
Therefore, option B, plant cells need chloroplasts to make food because most plants cannot move to get food on their own.
