How does the cardiovascular system/ respiratory system/ nervous system/ digestive system work together?
Answers
Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide. Your digestive system absorbs water and nutrients from the food you eat. Your circulatory system carries oxygen, water, and nutrients to cells throughout your body.
(1) Inhales (breathes in) Oxygen - good for the body - gives it to the Circulatory System to be transported throughout the body through the blood.
(1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.

The human body contains trillions of cells, 78 different organs and more than 60,000 miles of blood vessels if you stretched them end-to-end. Incredibly, all of these cells, vessels and organs work together to keep you alive.
Each organ belongs to one of ten human body systems. These body systems are interconnected and dependent upon one another to function. Your heart does not beat unless your brain and nervous system tell it to do so. Your skeletal system relies on the nutrients it gains from your digestive system to build strong, healthy bones.
There are 10 body systems:
Circulatory
Respiratory
Nervous
Muscular
Skeletal
Digestive
Endocrine (hormones)
Lymphatic, or immune system
Reproductive
Integumentary (skin, hair)
A body system is a group of parts that work together to serve a common purpose. Your cardiovascular system works to circulate your blood while your respiratory system introduces oxygen into your body.

A body system is a group of parts that work together to serve a common purpose. Your cardiovascular system works to circulate your blood while your respiratory system introduces oxygen into your body.
Each Body System Works with the Others
Each individual body system works in conjunction with other body systems. The circulatory system is a good example of how body systems interact with each other. Your heart pumps blood through a complex network of blood vessels. When your blood circulates through your digestive system, for example, it picks up nutrients your body absorbed from your last meal. Your blood also carries oxygen inhaled by the lungs. Your circulatory system delivers oxygen and nutrients to the other cells of your body then picks up any waste products created by these cells, including carbon dioxide, and delivers these waste products to the kidneys and lungs for disposal. Meanwhile, the circulatory system carries hormones from the endocrine system, and the immune system’s white blood cells that fight off infection.
Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles. The circulatory system provides your brain with a constant supply of oxygen-rich blood while your brain regulates your heart rate and blood pressure.
Even seemingly unrelated body systems are connected. Your skeletal system relies on your urinary system to remove waste produced by bone cells; in return, the bones of your skeleton create structure that protects your bladder and other urinary system organs. Your circulatory system delivers oxygen-rich blood to your bones. Meanwhile, your bones are busy making new blood cells.
Working together, these systems maintain internal stability and balance, otherwise known as homeostasis. Disease in one body system can disrupt homeostasis and cause trouble in other body systems. If you become ill with the AIDS virus that affects your immune system, for example, you may develop pneumonia in your respiratory system, a yeast infection in your reproductive system, Candida that affects your esophagus in your digestive system or the skin cancer known as Kaposi’s sarcoma.

The flow of carbon between inorganic and organic sources in the environment is best description of the carbon cycle as a whole. Thus, option B is correct.
What is carbon cycle ?It is the process in which carbon compounds are interchanged among the biosphere.
For example the elemental form of carbon such as diamond and graphite in a combined state are mostly found as carbonates and as carbon dioxide gas.
It act as a blanket over our earth, by balancing the energy and also absorb sun's long wave length radiation.
It also involve in plant photosynthesis, bioaccumulation of carbon occur in animal body by consuming plant material, after the death of the animal it can decomposed and carbon is released back into the atmosphere.
The carbon which is not released back will form fossil fuels.

If you were to hike up Mount Kilimanjaro in Tanzania, you would pass through several habitats, including savanna at the base, forest on the slopes, and alpine tundra near the top. Explain how such diverse habitats can be found at one location near the equator.
Answers
Given our knowledge of ecosystems, we can confirm that the diverse habitats found at one location near the equator are due to the changes in elevation.
The effects that elevation has on the climate are what enable the diversity of habitats on a single mountain. As elevation increases, atmospheric pressure decreases. This decrease in pressure then causes a decrease in temperature.
The base of the mountain is a dry and hot habitat, while as we travel upwards towards higher elevation we see a transition in habitats into a more tropical forest style and then eventually an alpine tundra, further proving the claim that elevation lowers the temperature.

I it is placed in a hypotonic solution it will gain water and eventually burst and if placed in a hypertonic solution it will lose water and shrink.
it must be bathed in solution with the same osmolarity as the organ tissue.
Osmosis allows for the diffusion of water from the region of higher concentration to the region of lower concentration.
Osmolarity measures the amount of solute concentration
For an organ place in a hypertonic solution i.e solution that has a higher solute
organ bathed in a hypertonic solution will continue to absorb in more water which can eventually burst the organ when it is too muchFor organ in hypotonic solution i.e solution that has a lower solute concentration
organ bathed will have to lose more solution because itself has more solute than the solution and can lead to shrinkagebut when the osmolarity is the same the Organ will have the same solute concentration as the solution and will help keep the organ in its original form, it will not absorb or lose any solution.

5. Why do you think it's important to look at the impact on the ecosystem as a whole, instead of just the individual"?
Answers
Answer:
Ecosystem Services are the benefits nature provides to human well-being. The term is frequently thrown around in academic circles, but why should you care about them?
Although the term is quite new, our connection to nature is not. We depend on nature for our survival - without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. We also enjoy nature... studies show that people who spend time in nature tend to be happier than those that don’t. It can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the trade-offs we are making between nature and industrial development.
This brings us to the reasons why we feel Ecosystem Services are important to each and every person:
1. Boundless Benefits
Understanding nature in economic terms, while not perfect, allows us to put everything into the same comparison unit. Despite nature being such an integral part of the human existence, it is sometimes an afterthought in today’s economy. Nature and money are often on competing terms, so to make a more level playing field, environmental economists have tried to bridge this gap by placing a monetary value on the benefits nature provides.
A recent study estimated the combined benefits of nature to people at well over $100 USD trillion per year. To put this in perspective, the top 50 most profitable companies globally combine to make just under $10 USD trillion per year.
Valuing nature in a way that can speak to decision makers, may help promote conservation efforts in the future. It brings nature back into the cost-benefit discussion in a way that can be easily understood.
2. The Foundation For Sustainable Development
Ecosystem Services help measure the true cost of industrial development. Often, the impact industrial development has on the economy and job creation overshadows the cost it will have on surrounding lakes, forests, keystone species, and so on. Assigning a dollar value to these lakes and forests, and the Ecosystem Services they provide, helps adjust the cost benefit analysis by evaluating the negative effects development will have on the natural environment.
Companies have also started to use Ecosystem Services in conservation offset planning, where they can buy and sell credits to offset a development or set aside land to meet a specific offset. Sustainable development supports the maintenance of a healthy economy while also protecting the ecological process for future generations.
3. Essential For Our Survival
Whether you live in rural Newfoundland or downtown Los Angeles, your dependence on Ecosystem Services is the same. As a society, we depend on healthy ecosystems to do many things; to purify the air so we can breathe properly, sequester carbon for climate regulation, cycle nutrients so we have access to clean drinking water without costly infrastructure, and pollinate our crops so we don’t go hungry. As the world’s population continues to grow, so too does our dependence on healthy ecosystems to provide the necessities essential to our survival.
Don’t we all want to leave the planet in a good condition for our successors? Ecosystem Services valuation and assessment is one way to help make this happen. By clearly understanding their value, we can make the best and most informed decisions about how to manage our landscape to ensure this value isn’t lost.

Please expand these bullet points
Answers
Answer:
The endocrine system is a major system in the body composed of glands that secrete hormones, which are substances produced by the body to stimulate an organ or group of cells. The endocrine system controls essential bodily functions, which include movement, sexual development, sensory perception, and even growth.
Explanation:
Hormones are chemicals that are produced by the glands in the endocrine system and coordinate distinct bodily functions by carrying important messages throughout the body. They send signals to receiver cells in organs, muscles, and tissues.
Role of Hormones
Hormones have very essential roles in the body, as they regulate metabolism, growth, and sex development. For example, testosterone and estrogen are sex hormones that are released in the body to initiate sex development during puberty. The rate at which these hormones are produced and released must also be highly controlled for optimal development and growth. Hormones also control levels of hunger or exhaustion. Overall, they are very important in telling the body what to do and how to do it.
Function of Hormones
As previously mentioned, hormones serve several important functions throughout the body. They are responsible for the function of organs, in addition to controlling how the body stores and uses energy. Hormones only target specific organs or cells: for example, thyroid-stimulating hormones are released by the pituitary gland, and only target the thyroid gland. Some hormones can affect several kinds of tissues at once; for instance, the thyroid hormone, produced by the thyroid gland, can affect several bodily functions, such as heart rate and metabolism.

Explanation:
Because humans are the only natural host for S. pneumoniae, our data suggest that the CbpA-mediated recruitment of complement FH may contribute to host tropism of this pathogen. A person can spread the germs that cause pneumonia when he or she coughs and expels the bacterial or viral infections that caused the disease. The droplets containing the virus or bacteria can land on a common surface, such as a table, telephone, or computer. Anyone can get pneumococcal disease, it occurs more frequently in infants, young children, the elderly or in people with serious medical conditions such as chronic lung, heart or kidney disease.

Answers
The correct option is B.
Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.
Alpha‐gamma coactivation is a process that the muscle use to keep or maintains it's length. It works in a way that when the muscle contracts or relaxes , the sensory neuron send the information to the central nervous system about what happen to the muscle. This lead the intrafusal and extrafusal fibers to contract.
Alpha-gamma coactivation enhance the muscle spindles ensure its sensitivity to stretch the muscle lengths.
Therefore, Alpha gamma coactivation is critical for maintaining the appropriate tension on the spindle organ during contraction of extrafusal fiber.
