What function is shared by both the skeletal system and the muscular system?
warming the body
protecting vital organs
creating red blood cells
fighting bacterial infections
Skeletal system and the muscular system help in protecting vital organs.
What is skeletal system?The skeletal system aids in defending the body's essential organs. The body's bones and joints are all part of the skeletal system. Each bone contains several cells, protein fibers, and minerals to form a complex living organ.
The soft tissues that make up the rest of the body's soft tissues are supported and shielded by the skeleton, which serves as a scaffold. Muscles can link to the skeletal system at specific places to enable joint mobility.
One of the three important muscle tissues in the human body is found in the skeleton. Thousands of muscle fibers are encased in connective tissue sheaths to form each skeletal muscle. Fasciculi are the individual bundles of muscular fibers that make up skeletal muscles.
Therefore, Skeletal system and the muscular system help in protecting vital organs.

Our modern environment may be affecting the endocrine system and reproductive systems in today's young people. Products such as plastics and industrial chemicals are considered endocrine disruptors. Air pollution, pesticides, and other chemicals have a damaging effect on these body systems. How do you think you can protect yourself from being affected from such exposures? What steps should be taken to ensure that people are not overexposed to any harmful substances?
Some ways to protect from the overexposure to the different kind of contaminants that surround us in this modern environment are:
• Try to consume the most organic and home-made food, avoiding ultra-processed and fast food.
,• Choose hygiene and cleaning products with the less amount of chemicals possible and use them in adequate amounts.
,• Use responsibly medicaments, especially antibiotics.
,• Avoid contaminated areas such us water, or regions very close to farms that are fumigated.
,• Use sunscreen and avoid solar exposure at the high risk hours.
Steps that should be taken to ensure that people are not overexposed to any harmful substances is to regulate by laws the allowed amouns of this substances in the products we consume, and near the places we live. An example of this is the maximum number of x-rays allowed per person a year due to radiation.

Why are Somali villages with sustainable grazing considered outliers? Based on your answer, how would you define an outlier?
Despite years of drought, a few Somali settlements have maintained excellent rangeland, making them outliers.
Outliers are data points, people, or communities that deviate from the norm.
This is further explained below.
Somali villages with sustainable grazing:Generally, Because they have been able to keep healthy rangeland throughout years of severe drought, the few Somali villages that have sustainable grazing are regarded to be outliers. This is in contrast to the bulk of the communities, which have not been able to preserve good rangeland.

What is osmosis? Describe this process including the types of molecules that move and the energy required. Include in your description details about the areas of concentration on either side of a membrane when osmosis occurs.
Answer:
Osmosis: Water diffuses through a semipermeable membrane during osmosis, a particular type of diffusion.
Explanation:
Water easily travels across a membrane in a potential gradient from high to low. Osmosis, one of the most important natural processes, is a natural occurrence. A weaker salt solution will often migrate to a stronger salt solution throughout this process. Reverse osmosis is capable of eliminating up to 99%+ of the dissolved salts (ions), particles, colloids, organics, bacteria, and pyrogens from the feed water, yet it shouldn't be relied upon to entirely remove bacteria and viruses. A RO membrane rejects contaminants based on their size and charge. A correctly operating RO system will likely reject any pollutant with a molecular weight more than 200 (for contrast, a water molecule has a molecular weight of 2).
A few calculations are employed for both design considerations and performance evaluation of a RO system. Instrumentation in a RO system shows quality, flow, pressure, and occasionally other information like temperature or operating hours. The following operational metrics are necessary in order to appropriately assess the performance of a RO system, at the very least:
Feeding forcePermeate forceIncrease your pressure.Charge conductivityTransparent conductivitySupply flowfluid permeationTemperatureREJECTION OF SALT %
You may determine from this equation how well the RO membranes remove impurities. It provides information on the system as a whole rather than the performance of each individual membrane. 95% to 99% of most feed water impurities will be rejected by a RO system that is well-designed and has RO membranes that are operating effectively (that are of a certain size and charge). The following equation can be used to calculate how well the RO membranes are eliminating contaminants:
Conductivity of Feed Water - Conductivity of Permeate Water 100; Salt Rejection%
Feed Conductivity
The system works better the higher the salt rejection. A poor rejection of salt may indicate that the membranes need to be cleaned or replaced.
PASSAGE SALT
This is the percentage of salts flowing through the RO system in terms of quantity. The method works better the lower the salt channel is. A high salt passage could indicate that the membranes need to be cleaned or replaced.
(1 minus Salt Rejection%) = Salt Passage
RECOVERY
Water that is being "recovered" as good permeate water is measured by percent recovery. The quantity of water that is not drained as concentrate but is instead collected as permeate or product water is another way to conceive of percent recovery. The higher the recovery percentage, the more permeate water is being saved and less water is being sent to the drain as concentrate.
There are many industrial applications that call for demineralized or deionized water, and reverse osmosis is a reliable and efficient technology to generate water that is suited for these uses. The quality of the RO permeate can be improved through additional post-treatment after the RO system, such as mixed bed deionization, making it appropriate for the most demanding applications. An RO system's proper pretreatment and monitoring are essential for avoiding expensive repairs and unforeseen maintenance. Your RO system should deliver high purity water for many years if it is designed properly, has a maintenance schedule, and is supported by knowledgeable service personnel.

why it is difficult to accurately quantify the quantum of carbon released from terrestrial ecosystems that are as a result of land-use change.
It is difficult to accurately quantify the quantum of carbon released from terrestrial ecosystems because Land uses and land cover changes have remarkable environmental outcome at local, regional, and global scales.
In terrestrial ecosystems carbon is stored within biomass, such as tropical and temperate forests. Carbon is transferred to the soil via leaf litter, roots and plant debris upon decomposition. Bacteria contributes in decomposition of dead matter to releases Carbon back to the atmosphere. So the land usage changes may cause intense inference at the regional and global scales for global loss of biodiversity, distresses in hydrogen and carbon cycle .

How does myasthenia gravis develop in relation to the immune system?Myasthenia gravis causes antibodies to be produced by your immune system that either block or harm many acetylcholine receptor sites in your muscles. Because there are fewer available receptor sites, your muscles get fewer nerve impulses, which results in weakening.
