Winds are light at the equator because of the weak horizontal pressure gradients located there. The warm surface conditions result in locally low pressure. ... At this latitude surface high pressure causes the air near the ground to diverge.
        
             
        
        
        
Animals such as bees or wind can carry pollen from one flower to another flower and fertilize the plant that way. Plants can also self-pollinate which happens when a plant’s own pollen fertilizes its own ovules.
        
             
        
        
        
Answer:
Filip's medical report, diagnosed with Alzhaimer's, may reveal a diminished production of acethylcholine.
Explanation:
Alzhaimer's disease is a neurodegenerative condition that causes immediate memory loss, behavioral changes and cognitive impairment, due to neuronal alterations and atrophy.
The neurotransmitter acetylcholine —related to neuronal transmission and body movement— may experience a decrease in its production leading to Alzheimer's, according to the cholinergic hypothesis.
Many therapies and treatments at present are based on the use of drugs to correct the acetylcholine deficit.
Regarding other options:
- <em>Dopamine: alteration or deficit is related to Parkinson's disease.</em>
 - <em>Gamma aminobutyric acid (GABA): deficiency is not common and is related to a type of congenital and infantile neuropathy.
</em>
 - <em>Serotonin: deficit of this neurotransmitter can lead to depression and psychological disorders.</em>
