Environmental conservation protects wildlife and promotes biodiversity. Maintaining a healthy and functional ecosystem helps prevent the extinction of certain animal species. If the environment is destroyed, some animals are forced out of their habitat, making it hard for them to survive elsewhere.
Mutation is the source of differences in the dna code.
What is Mutation?
- A mutation is a permanent change in the DNA sequence of an organism.Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
- Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
- Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.

Answer:
B. acidity of the vagina
Explanation:
The genus <em>Lactobacillus</em> includes rods and coccobacilli that lack catalase and produce lactic acid as the main fermentation product. <em>Lactobacilli </em>grow optimally under slightly acidic conditions. They are part of the normal flora of the human body and are present in the intestinal tract, vagina, etc.
In the human female vagina, the <em>Lactobacilli </em>are rarely pathogenic and rather serve as antimicrobial agents and prevent the growth of pathogenic microbes by imparting acidic pH to the vagina. Production of lactic acid by these bacteria imparts acidic pH and allows them to serve as antimicrobial agents.
In biology, the inner lining of tubular structures is called a lumen.
This can refer to numerous tubular structures in the body, such as the lumen of the veins and arteries, the lumen of the intestines or the tubes in the kidneys.
This term can also be used to describe a space defined by membranes of cell organelles such as the lumen of the mitochondria, the Golgi apparatus, and others.
True last scientific article I read which was not long again said that the gases that are in our air from space shows a neon color to it
