The correct answer is option C
The best way to classify the organism when they appear similar and found in the same area must be observed by studying the genotype of the organism.
Sometimes it is not possible to observe the change in the organism by looking physically( phenotype) so, in this case we must use the gel electrophoresis to compare the DNA pattern.
A negative result of monoculture farming is a decrease in mineral nutrients in soil.
<u>Explanation:</u>
When only one type of crop or plant variety is grown in a farming land at a certain period of time, it refers to Mono culture. It is a farming technique that is used industrial and also in organic way of farming. It is an efficient way for harvesting a particular species based on the season that supports their growth. The same way it also has disadvantages too. It can introduce many number of diseases and pests in the farming land.
The process of planting and harvesting the same plant variety in an area over a period of time will lead to the removal of nutrients that are present in that particular area. This is because the all the plants will be dependent on the same type of nutrients present in the soil and they will take that type abundantly. This will result in the eradication of that nutrient type from the soil resulting in making the soil very weak. Hence that farm area will not be suitable for growing other crops in a healthier way. This will lead to the use of fertilizers by the farmers that will again eradicate the soil nutrients.
Answer: D: They are closed at one end
Explanation:
"Lymphatic Capillaries" are tiny, thin walled microvessels located in spaces between cells and their main function is to drain and process extracellular fluid.
They are larger than blood capillaries and have "closed ends". Their unique structure permits interstitial fluid to flow into them but not out. Thus their ends are closed unlike the loop structure of blood capillaries.
I'm pretty sure this object is asymmetrical. So I would go with answer A.
A human is more closely related to a mouse than a kangaroo
