Answer:
Description
An electron cloud is the region of negative charge surrounding an atomic nucleus that is associated with an atomic orbital. It is defined mathematically, describing a region with a high probability of containing electrons.
Answer:
1,35 * 10 ^ -2 M
Explanation:
Recuerde que pH = -log [H ^ +]
Sea la concentración de iones de hidrógeno [H ^ +]
Si es así, entonces;
-pH = log [H ^ +]
Por lo tanto;
[H ^ +] = Antilog (-pH)
[H ^ +] = Antilog (-1,87)
[H ^ +] = 1,35 * 10 ^ -2 M
Polygenic because there are 2 distinct phenotypes
Humans maintain homeostasis in cold weather by the following ways:-
blood vessels constrict, pores close, metabolism increases.
green algea are closely related to plants. even though all living organisms that possess chloroplasts originated from cyanobacteria, their evolving order is as follows;The chloroplast of modern plants is thought to have undergone through the following sequence
cyanobacteria→green algea→plants. so it is clear that plants are closely related to green algea because plants evolved from them
