Answer:
lol xd free points if u wanna c my face check my most recent question
Explanation:
Biodiversity is essential to an ecosystem's resistance against viruses and famine. In history, there has been many cases in which a lack of biodiversity has allowed a virus or disease to endemically wipe out an entire species of plant. This will subsequently affect all consumers of each trophic level. Ex: A disease that attacks the DNA of only one certain species of plant would cause decreases in the population of the organisms that rely on eating that plant, the organisms that rely on eating those organisms, and so on. This is caused by a decrease in food source, thus not being able to sustain the ecosystem's demand, thus naturally killing off any organisms that would not be able to find a sufficient food source.
In recent molecular genetic studies, genes associated with the neurotransmitter Dopamine have been linked to ADHD.
ADHD stands for Attention Deficit Hyperactivity Disorder. People with ADHD have a hard time focusing on tasks. Scientists have found that the low levels of dopamine in the brain are associated with the symptoms of ADHD. It is because the neurons in the brain have a high amount of protein called the dopamine transporters. These proteins block the dopamine from passing between the neurons. This decreases the effect of dopamine.
1. False ( Its also used to hold up other plants, its a wooden arch)
2.False (cover crops are crops planted to prevent soil erosion not to harvest, think grass)
3.False (depends on the wine, but no wine is harvested during maximum sugar content. The more sugar the higher the alcohol content)
C)temperature and rainfall
Explanation:
Temperature and rainfall are the most important physical factors that shapes the characteristics of an ecosystem.
Temperature is the degree of hotness or coldness of a place. It is mostly as a result of the solar radiation it receives.
Rainfall is a form of precipitation in which water falls under gravity in liquid form.
They are both by far the most important factors that shapes ecosystems.
