Explanation:
Skin is a barrier that serves as one of the body's first lines of defense against harmful microbes. Specialized immune cells within skin tissue help to fight invading organisms. Past work by an NIH research team showed that commensals can help the body's immune cells fight disease-causing microbes.

Answer:
Large areas of the earth with similar climate and ecosystems are called biomes.
Explanation:
Biomes are defined as areas of the planet with common characteristics, such as animal and plant species, as well as climate, which is why it is called a bioclimatic landscape.
When a relationship is established between an ecosystem —with all its biotic and abiotic components— and the climate in a given area, reference is made to a biome. Consequently, a <u>biome represents large areas of land with similar geographical, climatic and biological conditions</u>.
The other options are not correct because:
- <u><em>Communities</em></u><em> are groups of individuals with common characteristics.
</em>
- <u><em>Populations</em></u><em> are individuals of the same species that occupy a certain space in a certain time.
</em>
- <u><em>Organisms</em></u><em> are synonymous with living beings.</em>
Answer:
The correct answer will be option-Base analog
Explanation:
5-bromodeoxyuridine is a synthetic nucleoside which is formed by deaminating the 5-Bromodeoxycytidine.
The BrdU once incorporated in the DNA of replicating cell during S phase binds the adenine which shows that it replaces the thymidine which usually binds the adenine.
Since BrdU binds the adenine, therefore, it acts as the analogue of the thymidine and also can cause mutations thus acts as a mutagen.
Therefore, it acts as a base analog and thus is the correct answer.
