Skin is the first line of defense mechanism of our immune system. It acts as a barrier for pathogenic and opportunistic microorganisms. However, skin itself has a microbiota that does not allow other microorganisms to invade or colonize. Any wound, cut or change in the pH of skin due to environmental conditions or any disease might lead to the entry of the opportunistic microorganisms inside the skin. This leads to several skin disorders such as dermatitis, eczema, cellulitis, warts, etc. Thus, it is extremely important to keep the skin hydrated and healthy to avoid any kind of microbial invasion.

Answer:
A. It results in the number of chromosomes being reduced by half.
Explanation:
In the process of meiosis, one cell is divided 2 times to form 4 daughter cells. These 4 daughter cells have half the number of chromosomes that of the parent cell.
Answer:
<u>Chloroplast</u>
The chloroplast is where photosynthesis occurs in plant cells. During photosynthesis, sunlight energy, carbon dioxide, and water are converted into simple sugars (glucose). These simple sugars are cell's version of food.
<u>Mitochondria</u>
The mitochondria is where cellular respiration occurs. During the process of cellular respiration, glucose, which is produced through photosynthesis in the chloroplasts, is broken down into cellular energy that can be used by the cell.
- Both chloroplasts and mitochondria are organelles that generate metabolic energy.

Answer:
The correct answer is option b, that is, four-field approach.
Explanation:
Anthropology refers to the study of human beliefs, behavior, and adaptations. In order to completely comprehend any aspect of human behavior, the field of anthropology adopts a four-field approach. The four sub-disciplines of anthropology are archaeology, cultural anthropology, biological anthropology, and linguistic anthropology.
In archaeology, materials are used generally from past cultures, in order to understand and illustrate human behavior and adaptive strategies via time. Biological anthropology refers to the study of humans as biological species, the research areas comprise diversity in modern human populations, human evolution, and medical anthropology.
The cultural anthropology explores patterns of behavior and belief in historical and contemporary cultures all over the globe. The linguistic anthropology studies and documents languages in terms of acquisition, structure, and use in the transmission of culture. As can be seen that each of the sub-disciplines focuses on distinct characteristics of human adaptation, however, when taken together in a four-field approach it offers a powerful tool for gaining a complete understanding of any aspect of human behavior.
