Answer:
Chromatin helps regulate DNA replication.
Explanation:
Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
Answer:
Unlike the one-way flow of energy, matter is recycled within and between ecosystems.
Explanation:
Answer:
La Nina is a climate pattern which refers to the changes in the sea-surface temperature of the eastern tropical Pacific along the west coast of South America.
La Niña is considered as the cold phase of El Niño-Southern Oscillation (ENSO) cycle as it lowers down the surface ocean water.
This shows effects on global atmospheric circulation, rainfall patterns and atmospheric pressure as it affects the rainfall- in some parts like Malaysia causes heavy rainfall and in some creates dry conditions. It also affects the weather pattern as in Canada.
Intraspecific competition drives natural selection,as individual members of a species compete with each other for limited natural resources.
