Answer:
The earliest primates are found in the Paleocene epoch. :)
Organisms depend on buffer that are compounds that stabilize pH by absorbing or releasing h ions. It consists of weak acids and weak bases.
The buffer is also consists of undissociated acid (HA) and the ions that are made by dissociating the acid (A-). Because of the presence of weak acids and bases and to stabilize the pH the buffer absorb or give off H+.
The nucleic acids must have positive charge that helps in formation of double helices.
Undissociated acid means when an acid dissociates to release a proton to make the solution acidic.

Answer:
Protons,neutrons
Explanation:
Inside atom,the entire mass of it lies in nucleus.
So,we knew that mass of atom= no of protons+ no of neutrons
hence from we understand,nucleus contain both protons and neutrons
Answer: how changes in biodiversity impact an ecosystem
Explanation:
Water hyacinth is an invasive special that is introduced to an environment. It spread rapidly and causes enough damage to bother human,economy and environment.
Hyacinth pollutes the water causing a decrease in oxygen level and other nutrients like passport and nitrogen and it lead to high concentration of heavy metals and contaminant.
It can blankets the ocean causing a decrease in photosynthesis, boat trafficking, swimming and movement of organism in water bodies. It demostrates how changes in biodiversity impact an ecosystem.
