Answer:
This question is incomplete as it does not contain the graphical representation of fishes population over time. The image containing this information has been attached in the attachment section.
The correct answer is D. The nitrogen from the fertilizer made the plants grow too quickly, which hurt the fish.
Explanation:
According to the attached image, artificial fertilizer is being used on a an apple orchard for six years. The orchard is located near a stream which runs out into a small bay.
Based on the results of the sampled population of fishes for five years as represented graphically by researchers (see attached image), it is obvious that the population of the fishes in the bay is reducing over the years. They also observed the growth of plantlike organisms in the bay.
The possible cause of this decline in the population of fishes is the increased growth of these plantlike organisms. The plantlike organisms are algae, which uses the nitrogen content of the artificial fertilizer that washes into the bay from the orchard, as a source of nutrient. This excessive nutrient causes the plantlike organisms to bloom or grow too rapidly- a process called EUTROPHICATION.
Eutrophication causes the oxygen content of the bay to reduce gradually as the blooming of the plantlike organisms depletes oxygen in the water body, thereby, harming aerobic aquatic organisms like fishes in the bay.
Hence, in a nutshell, the reduction in the population of fishes in the bay is as a result of the nitrogen from the fertilizer which made the plantlike organisms grow too quickly, leading to oxygen-depletion and subsequently death of the bay fishes.
Answer:
Chloroplast
Explanation:
Endosymbiosis theory explains the origin of chloroplast and mitochondria in the eukaryotic organisms.
When the pro-eukaryotes engulfed the blue-green algae or photosynthetic bacteria, these bacteria formed the symbiotic relationship with the pro-eukaryotes. These photosynthetic bacteria transformed into the chloroplast organelles of the eukaryotes which can capture the sunlight and use it in the synthesis of glucose molecules. These eukaryotic cells later formed the plant kingdom.
Thus, the chloroplast is the correct answer.
Answer:
2) JG cells are present in the vasa recta.
Explanation:
The vasa recta is a web of the blood capillary which supply blood to the medulla region of a kidney due to its high permeability of solutes and water. It runs parallel to the loop of Henle. It does not composed of the juxtaglomerular cells (JG cells). The juxtaglomerular cells (JG cells) present in kidney which synthesise and stores enzyme renin. Thus, option 2) JG cells are present in the vasa recta is not a true statement.
Its mutton, because the sheep is at least 2 years old, thus the butcher is correct, come on chef. if youve been cooking for long long then how would you not know it isnt mutton by now?
Answer:
Nerve cells are called neurons . They are adapted to carry electrical impulses from one place to another. ... at each end of the neuron are tiny branches (dendrons ), which branch even further into dendrites . The dendrites receive incoming nerve impulses from other neurons
