Answer:
The answer is C. Fertilizers
Explanation:
Plants, like animals, require certain nutrients for optimal growth and development. The soil is the primary source of nutrients for plants. <u>Some </u><u>nutrients</u><u> like the following are </u><u>crucial for the plant development and growth.</u>
- Nitrogen (a key element in plant proteins and hormones)
- Phosphorous (required for early root and plant growth), magnesium (required for production of chlorophyll)
- Sulfur ( an element in proteins)
- Potassium (improves fruit quality, enhances growth and disease resistance)
- Apart from these, metals like copper, iron, manganese, zinc and molybdenum are required for growth in trace amounts.
Fertilizers:
- <u>Fertilizers are artificial or natural forms of these nutrients</u> that are added to the soil or the plant to enhance growth and development.
- A fertilizer can either be one nutrient or a combination of the aforementioned nutrients. For example, urea is a purely nitrogen based fertilizer whereas potassium phosphate fertilizer is a combination of two nutrients.
- Fertilizers are supplied to the plants in a readily available form.
- Fertilizers help in increasing the crop yield.
If you skipped metaphase during mitosis it would not give the daughter cells the same amount of chromosomes
Answer: The correct answer is a) Peroxisomes.
Explanation: This kind of membrane enclosed organelles has a mainly function that is the oxidation, this source manages to break fatty acids and during normal metabolism, they also has many enzimes like d-aminoacid oxidases, is another of their functions. Further, the catalase enzime (another enzime which is inside peroxisomes) manages the detoxification of chemicals like alcohol from alcoholic drinks (catalases transform the H2O2, which is toxic, into H2O to detoxificate the liver).
Natural pollution includes smog. Smog is a combination of smoke in an air and fogs.
When you say natural pollution, it is not being caused by human rather caused by a natural resources or organism.
Falling leaves are natural, but its not a pollution.
<span>if a molecule is too large it cannot pass. also it depends on the concentration of a specific substance inside the cell. similarly, if a molecule is polar it cannot penetrate the phospholipid bilayer.
there are proteins that work as channels and pumps that allow these molecules to pass
