The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes.
Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

<u>random mutations:</u>
What is commonly called "random mutation" does not in fact occur in a mathematically random pattern. The process of genetic mutation is extremely complex, with multiple pathways, involving more than one system. Current research suggests most spontaneous mutations occur as errors in the repair process for damaged DNA.

the activity or condition of competing.
<u>environmental changes:</u>
Examples of these global environmental changes include climate change, freshwater shortages, loss of biodiversity (with consequent changes to functioning of ecosystems), and exhaustion of fisheries.
The tissue level or organization refers to a group of cells of the same origin that carry out a specific function. It can be viewed as a group of cells that don't necessarily make up an organ. The tissue level or organization refers to a group of cells of the same origin that carry out a specific function.
They can either lose or share electrons when they combine with other elements. So, depending on the conditions , these elements can behave as either metals, or non-metals. I hope my answer has come to your help. God bless and have a nice day ahead!
