The major threat to humans and the most prominent selection pressure are disease organisms that target the immune system.
These organisms impair the body's ability to fight off invasion from pathogens, and there is no "back up immune system" to protect the immune system from attack. An example of a pathogen that attacks the human immune system is the Human Immunodeficiency Virus (HIV).

defon
Glucose is the main provider of energy for the brain and the nervous system. Because the brain is so rich in nerve cells, or neurons, it is the most energy demanding organ, using one half of all the sugar energy in the body.

Wittaler [7]

Answer:

the order would be:

Carnivorous animal -> scavenger animal ---> autonomous living organism ---> decomposing organisms.

Explanation:

The lion would be the carnivore, the bird that eats the waste of dead meat would be the scavenger, the vegetable the autonomous, since it does not require an external energy source to live but synthesizes its own energy and finally the decomposers fulfill the function to decompose chemical compounds to give energy to the earth, which would be useful for the growth of other living organisms. This is how the chain meets the cycle of life.

How would you characterize the style of parenting under which you were raised? Was the same style used by both of your parents?
krek1111 [17]

Answer:

Explanation:

I have been raised under an autthoritative parenting style, and my parents were both raised under an authoritarian style (it was more evident in my mother, because my father's mum died when he was 13). I think it was authoritative because they didn't let me do whatever I wanted, but they also didn't keep so much control on me, so I had certain level of freedom, as long as I didn't break anything xD
