Answer:
The human body inhabits various microbes, which coexist and does not cause any kind of harm, these bacteria are considered as good bacteria and are known as microbiota. Even the skin comprises various categories of bacteria, that is, more than 500 species. These microbes demonstrate skin microbiota, that is, an effective system of safeguarding, which takes place in immune defenses.
The beauty of the skin is nearly associated with the balance of the microbes, which populate it, these are considered as the first line of defense from outside threats. When the bacterial ecosystem is differentiated and balance, the skin stays healthy.
It has been hypothesized that over-washing of hands diminishes the population of good bacteria from the skin. As it is considered that over-washing extricates the majority of the beneficial bacterial cells from the human skin. Hence, may result in the loss of natural microflora from the section of the skin.
Answer:
a mutation in the germinal line changed the phenotype to bright flowers which were capable of attracting more pollinators compared to yellow flowers. Subsequently, this mutation was selected by natural selection, thereby increasing its frequency in the population
Explanation:
A mutation is any change in the nucleotide DNA sequence of the genome of a particular organism. Mutations can be divided into 1-germinal mutations (i.e., mutations that occurred in the gamete cells) which can be passed on to offspring, and 2-somatic mutations (i.e., mutations that occurred in the somatic cells), which cannot be inherited. Moreover, mutations can be neutral, deleterious or beneficial depending on the environment in which the organism lives. When a germinal mutation is beneficial, the organism carrying the mutation will have more chances to survive and reproduce (i.e., a higher adaptive fitness), thereby the organism will have more chance to pass this mutation to the next generation and the mutation will increase its frequency in the population.
Explanation:
The rate of water uptake by the plant would be greatly reduced.
Root hairs increase the surface areas to volume ratio by which the roots absorb water from the soil. This means the plant will not be able to effectively replace water lost by evapo-transpiration and the plant will wilt especially on a hot day.
