Think about a bush in your back yard. Is it alive according to the characteristics of life? Why or why not?​
SVETLANKA909090 [29]

Konichiwa~! My name is Zalgo and I am here to help you out on this amazing day. According to my knowledge and evidence, I would say that the bush is very well alive. It grows, it provides you an element that you need to survive, and if you cut it down to a size you like, all it will do is grow back up.

I hope that this info helps! :D

Distinguish between directional, stabilizing, and disruptive selection. Give examples.
Pepsi [2]
Distribution of phenotypes within a population may be impacted by different types of natural selection. These types of selection include;
Directional selection involves a change in the environment shifts of phenotypes observed. Example is the giraffe neck-length, where the length got longer and longer over time to reach the leaves at the top of trees.
Stabilizing selection , this is a selection where an average phenotype is favored. example is number of eggs laid by birds such that too many eggs will be a waste of energy because some chicks would starve.
Disruptive selection is a selection where individuals with an average value of a trait are affected most while those with values below average are affected least. Example small individuals are capable of hiding from predators while big individuals can not fit in the hiding place but instead will fight with predators.
