Answer:
B. runoff of nitrates from fertilizers applied to the golf course
Explanation:
Algal bloom is defined as the rapid growth of algae in freshwater or marine water. Algal bloom is green or yellowish in color that cover the top layer of water systems.
Algal bloom in the given case is caused by the excess of nutrients that is nitrates from fertilizers into waters and higher concentrations of nitrates causes uncontrollable growth of algae.
Algal blooms are harmful for environment as they may produce toxins and can block the sunlight from reaching the plants and animals in the water systems.
Hence, the correct answer is "B. runoff of nitrates from fertilizers applied to the golf course".
Well, plants have a vascular system whereas animals have a circulatory system. They both utilize tube structures that transport water and nutrients to the cells and different parts of the organism. Plants have xylem and phloem and animals have veins and arteries. An animal's circulatory system is driven by a pump, via the heart. A plant's vascular system is driven simply by gravity and the many useful properties of water. Plants have water-based solutions within their vascular systems and animals have mainly white and red blood cells within their circulatory systems.
Answer:
Basolateral complex
Explanation:
Amygdala is that part which is situated at both the right and left side of the brain's temporal lobes that is believed to play a vital role in the evaluation of the emotions and the recognition of different situations and also helps to detect the potential harms.
Amygdala has further two parts, one is the central nucleus and the other is basolateral complex where the function of central nucleus is paying attention.
Basolateral complex is another part having dense connections and various sensory regions in the brain critical for the attachment of the evaluation of emotions to memory and learning.
