Identify three functions preformed by organ systems
The question you've asked is not clear, you haven't specified which organ system are you talking about. No worries, I've noted down key functions of 11 organ systems of the human body, you can pick any of them that you want.
Some of the main functions of the 11 organ systems include the following:
Skeletal system:
shape/support for the body
protect some organs (brain, heart, lungs, spinal cord, etc.)
mineral storage (e.g., Ca and P)
site for muscle connections
site for blood cell formation
Muscular system:
movement
since there are three types of muscle—cardiac, smooth, and skeletal—there are specific functions for all of these
Cardiovascular system:
pump blood throughout the body
the blood will transport nutrients, oxygen, waste, and hormones
the blood also functions as a part of the immune system and allows the white blood cells/antibodies to gain access to infected/wounded areas
Excretory system:
produce and store urine in the kidneys and bladder
release urine through the urethra
Digestive system:
digest food into nutrients that can be absorbed
absorb nutrients
make certain vitamins (e.g., Vitamin K is made by bacteria in the large intestine)
Reproductive system:
the main function here is to produce offspring
another function—in line with the endocrine system— is to make hormones (e.g., testosterone and estrogen, which affect male and female characteristics)
Endocrine system:
hormone production
these hormones act throughout the body performing multiple jobs (e.g., blood sugar levels [insulin/glucagon], growth [growth hormone], male characteristics like facial hair [testosterone]
Integumentary system:
this is the skin
protection from some pathogens (unless you get a cut)
sensations at the skin level (texture, heat, pressure, pain)
Nervous system:
made of the central (brain and spinal cord) and peripheral nervous systems
this system transmits signals from one part of the body to another and this includes your senses
Respiratory system:
this mainly includes your lungs and trachea
the main function is the exchange of gases (oxygen and carbon dioxide)
Immune system:
the main function is to defend the body against pathogens
this is done with the help of the cardiovascular system which has white blood cells and antibodies in the blood

The rate at which an object weathers is determined by many different variables. For example, compare the two ancient
Egyptian structures below.
Both structures were carved in Egypt from the same type of rock more 1,000 years ago. However, the obelisk in New York

In recent decades, average global temperatures have increased significantly. Scientists agree that the widespread destruction of the Amazon rain forest contributes to climate change. Which mechanism might be cited to support that hypothesis?
A Deforestation causes water on the ground to reflect sunlight.
B Deforestation reduces the number of plants able to absorb carbon dioxide.
C Photosynthesis produces energy, which gives off heat.
D Plants use up energy during cellular respiration.
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
The main reason causing average global temperature rise is increase in amount of green house gases like Carbodioxide, and since deforestation reduces a vast number of plants, so there is lack of plants absorbing CO2 causing this whole thing.
So, according to this the Correct choice is B
The mechanism that supports the hypothesis that the widespread destruction of the Amazon rainforest contributes to climate change is Deforestation reduces the number of plants able to absorb carbon dioxide. The correct option is B.
Forests, like the Amazon rainforest, play a crucial role in mitigating climate change because trees act as carbon sinks. They absorb carbon dioxide during photosynthesis and store it as biomass. When forests are cut down or destroyed through deforestation, the carbon stored in trees is released back into the atmosphere in the form of carbon dioxide, a greenhouse gas that contributes to global warming.
The Amazon rainforest, often referred to as the "lungs of the Earth," is particularly vital in this regard because of its vast size and high biodiversity. As large areas of the forest are cleared for logging, agriculture, and other human activities, the ability of the Amazon to absorb carbon dioxide diminishes, leading to increased greenhouse gas concentrations in the atmosphere and contributing to the warming of the planet.

What natural features are important in the transfer of sand from one side of an inlet to the other:
Answer:
What causes sand to move along a beach?
Sand grains move along the shore and up and down beaches because of currents made by waves. Waves break when they reach shallow water, creating turbulence. This area is called the surf zone. When waves break, some of the force is turned into currents
The natural features that are important in the transfer of sand from one side of an inlet to the other may include weathering and erosion.
How does sand move along a beach?Sand grains move along the shore and up and down beaches because of currents made by waves. Waves break when they reach shallow water, creating turbulence. This area is called the surf zone. When waves break, some of the force is turned into currents.
Most beaches get their sand from rocks on land. Over time, rain, ice, wind, heat, cold, and even plants and animals break the rock into smaller pieces. This weathering may begin with large boulders that break into smaller rocks. Water running through cracks erodes the rock. They also prevent seawater from entering wells and ponds.

Answer:
Ecosystem Services refer to the benefits that humans receive from the natural environment. They are the various processes and functions that ecosystems provide, such as the purification of air and water, nutrient cycling, and the provision of food, fuel, and fiber. Ecosystem Services are crucial for human survival and well-being, and they are essential for maintaining the balance of the planet's natural systems. One example of an ecosystem service is the pollination of crops by bees and other insects. Pollinators are responsible for fertilizing flowers, which allows plants to produce fruits, vegetables, and seeds. Without pollinators, many crops would not be able to produce a yield, resulting in a significant reduction in food production. Additionally, pollinators are essential for maintaining the diversity of plant species, which is essential for the health of ecosystems. The economic value of pollination services has been estimated to be worth billions of dollars annually. Another example of an ecosystem service is the role of wetlands in mitigating flooding and reducing erosion. Wetlands act as natural sponges, absorbing and storing water during heavy rainfall and releasing it slowly over time. This helps to reduce the risk of flooding downstream and prevents soil erosion. Wetlands also provide important habitats for a diverse range of plant and animal species, which supports the overall health and resilience of ecosystems. The economic value of wetlands in terms of flood control and erosion prevention has been estimated to be worth billions of dollars. In conclusion, ecosystem services are essential for human well-being and the health of the planet's natural systems. They provide a wide range of benefits, including food production, water purification, flood control, and erosion prevention. The examples of pollination and wetlands demonstrate how ecosystem services benefit people by supporting food production and reducing the risk of natural disasters. It is important to recognize the value of ecosystem services and to take steps to protect and conserve them for future generations.

What is the correct order of structures that a piece of food would encounter as it travels through the alimentary canal of a bald eagle?.
The correct order of structures is mouth, oesophagus, crop, stomach(proventriculus), gizzard, intestine, and anus.
The digestive tract of birdsThe digestive tract of birds starts from the mouth and ends at the anus.
As the food enters the oesophagus through the mouth, it is pushed down to the first stomach called the proventriculus.
Hydrochloric acid, mucus and a digestive enzyme, pepsin, are secreted by specialized cells in the proventriculus and start the process of breaking down the structure of the food material.
Food substances that are hard to digest are transferred to the gizzard. Nutrients are absorbed in the intestines and undigested food substances are removed through the anus.
