Well there are many catastrophic scenarios that we already overcome. You should consider educating yourself about the great filter. A great filter is a hypothetical barrier that each civilization can or cannot overcome. From here on things get a little complex so I won't bore you with them. But there are experts in this theory called great filter and I'm sure they can tell you a lot about.
DNA replication
After the process of DNA replication occurs, each daughter cell receives an exact copy of the parent cell's DNA.
DNA replication is a biological process by which a DNA molecule divides to produce two copies of itself during cell division. DNA replication takes place in all living organisms. During DNA replication, an enzyme known as helicase separates the double helix structure of the DNA molecule into two separate strands which serve as templates for making the new strands of DNA.
<h2>Depending on the organism, these needs may include: air, water, nutrients, food, light, shelter, space, certain temperatures, etc. Plants need soil, nutrients, sunlight, water, space, air and appropriate temperatures to survive. Animals need food, water, shelter, oxygen, space and appropriate. You can write: Organisms need air, water and food from their environment. I hope this helps you! </h2>
Answer:
DNA
Explanation:
The nucleus is a central placed organelle in eukaryotic cells. It is said to contain the "blueprint of life" known as the DNA. The DNA is a structure located in the nucleus of the cell that encodes information necessary for the growth and development of the organism.
This information encoded by the deoxyribonucleic acid (DNA) of the cell includes how the organism will reproduce, hence, DNA is called the blueprint of life.
