How does the integumentary system help maintain homeostasis

Biology
1 answer:
oee [108]3 years ago
8 0

Answer: The integumentary system is essential in maintaining homeostasis, a state of stability across factors like temperature and hydration, in the body. The integumentary system stores water and prevents dehydration as well as producing sweat to regulate temperature and rid the body of waste products

Explanation: Barrier protection and water transport can be demonstrated with a piece of fine cloth. Pour water with coarse sand in over the cloth. The sand (bad organisms) are kept out, but the water (sweat) can go through.

Insulation: Put a thermometer into a small block of styrofoam. Put the block on a piece of ice, and then in a cup of hot water and observe the temperature. That is how the skin helps to regulate body temperature.

Cooling: When we exercise a lot (running is good) we generate more internal body heat. Notice how exercise (work) or even just hotter temperatures in the cause us to sweat.

Measure the air temperature with a thermometer and a fan blowing over it. Then measure it again with the thermometer covered with a THIN wet paper towel. That is how our sweat cools our body by evaporation.

katrin2010 [14]

Answer:

Euglena is a single celled organism. It belongs to Kingdom Protista. Euglena is  a eukaryotic organism that exhibit characteristics of both plants and animals. Some species of Euglena are photoautotrophs like plants which means they have ability to trap sunlight to produce food by the process of photosynthesis. Whereas, some species are heterotrophs like animals which means they obtain food by feeding on other organisms.

If scientists remove all of the chloroplasts from a Euglena, it will not be able to perform photosynthesis because chloroplast is an organelle that contains light sensitive pigments named as chlorophyll. Chlorophyll traps light energy from sun. Sunlight energy, along with carbon dioxide and water produces food in the form of glucose in plants and other photoautotrophs.

zaharov [31]

Answer:

let's take the example of Walmart, which has the large presence in the United States and is an important part of the Consumer Services Industry.

Explanation:

Walmart began with just one store but has grown all over the country to many unique aspects of the American economy and demographics. The United States, in contrast to what many people assume, is a very diverse country.

The culture of New England is very different from that of the Bible belt. Similarly, the African American culture of Georgia is different from the casual California where there is a vast Hispanic population.

Walmart saw an opportunity in this diversity and has grown by catering to needs of all these consumers. Communities with highly dense Hispanic population stocked food items that were very different than can be found in Jewish neighbourhoods and vice verse.

This enabled Walmart to connect with each community and grow with them over the generations.

In all this, Walmart prides itself in providing benefits to US army veterans and provides jobs to women from low-income backgrounds and the disabled.

In all this, Walmart does face a number of different challenges, including:

A slowing economy can hit the profits of the company

Competition from other companies such as Costco and even international players like Aldi and Lidl can decrease their market share

Online rivals such as Amazon have long been identified as a threat to the company and is one of the biggest challenges facing the consumer service industry.

Companies like Amazon are not only involved in retail but also in selling movies, music, etc that can completely challenge the consumer service sector
