What would happen to the food that someone ate if they didnt have the digestive enzymes they needed

Answers

Answer:

The digestive system is my favorite system! Without it you would not survive. Our digestive system is how we break down food into nutrients that feed our cells and give us energy to move, talk, grow, think, reproduce, and all the other crazy things that humans do.

Although each of the parts of the digestive system has specific and important functions, shockingly, you can survive without some of the parts. For example, morbidly obese individuals can have their stomach entirely removed in a procedure called a gastric bypass. In this surgery, the small intestine is linked directly to the esophagus thus “bypassing” the stomach. You can also live without your appendix. In fact, it sometimes negatively impacts health as it can become infected (have you ever known someone who had their appendix burst?). The appendix was thought to be a “vestigial organ” meaning that at one point in evolutionary history, we humans had a need for it, but now we don’t; however, there is recent evidence that the appendix is an important hotbed for beneficial bacteria that help us digest food.

Explanation:

I hope this helps! Brainliest is always appreciated!

Answer:

They wouldn't be able to digest the food. It wouldn't break down like it's supposed to with the digestive enzymes.

Which structure does the immune system target in type 1 diabetes?
a. beta cells of the pancreas
b. liver cells that release glucose
c. insulin receptors on fat cells
d. red blood cells in the bloodstream

Answers

Answer:

The thymus plays an important role in deletion of potentially autoreactive T cells. However, the presence of islet-specific T cells in the circulation of type 1 diabetes patients and healthy subjects indicates that the thymus is not capable of efficiently deleting all autoreactive T cells (Mathis and Benoist 2009).

Explanation:

Answer:

A: beta cells of the pancreas

Explanation:

Type 1 diabetes makes the pancreas produce little to no insulin.

Explanation:

What has happened to Earth due to the pollution?

Answers

Answer:

OCEAN LITTER

Litter in the world’s oceans comes from many sources, including containers that fall off ships during storms, trash that washes off city streets into rivers that lead into the sea, and waste from landfills that blows into streams or directly into the ocean. Once in the ocean, this debris may degrade slowly and persist for years, traveling the currents, accumulating in large patches and washing up on beaches.

PESTICIDES AND FERTILIZERS

Use of pesticides and fertilizers on farms has increased by 26-fold over the past 50 years, fueling increases in crop production globally. But there have been serious environmental consequences. Indiscriminate pesticide and fertilizer application may pollute nearby land and water, and chemicals may wash into nearby streams, waterways and groundwater when it rains. Pesticides can kill non-target organisms, including beneficial insects, soil bacteria and fish. Fertilizers are not directly toxic, but their presence can alter the nutrient system in freshwater and marine areas. This alteration can result in an explosive growth of algae due to excess nutrients. As a result, the water is depleted of dissolved oxygen, and fish and other aquatic life may be killed

AIR POLLUTION

Air pollution brings to mind visions of smokestacks billowing black clouds into the sky, but this pollution comes in many forms. The burning of fossil fuels, in both energy plants and vehicles, releases massive amounts of carbon dioxide into the atmosphere, causing climate change. Industrial processes also emit particulate matter, such as sulfur dioxide, carbon monoxide and other noxious gases. Indoor areas can become polluted by emissions from smoking and cooking. Some of these chemicals, when released into the air, contribute to smog and acid rain. Short term exposure to air pollution can irritate the eyes, nose and throat and cause upper respiratory infections, headaches, nausea and allergic reactions. Long-term exposures can lead to chronic respiratory disease, lung cancer, and heart disease. Long-term exposures also can lead to significant climatic changes that can have far reaching negative impacts on food, water and ecosystems.

NOISE AND LIGHT POLLUTION

Artificial light and noise often drown out natural landscapes. In the Arctic, the sounds of oil and gas explorations are so loud that belugas, bowhead whales and other sea life have had difficulty feeding and breeding. Light pollution disrupts circadian rhythms for both humans and animals alike and may even contribute to the development of cancer. Light pollution also can impact sea turtles. Adult and hatchling sea turtles are drawn toward lights along the beach, thinking they are heading toward the moon. Coastal developments, therefore, are encouraged to turn off their lights or cover them at night

For example, you might write something like: "verbs always match nouns in number, and they usually come before the noun." In other words, make your best guess for the grammar rule that makes sense out of the pattern(s) you see in the phrases you have been working with.

Most of the boxes are full of many books, but one of the boxes was closed, only having a few books in it. You go to lift this box, not knowing it has less mass, with the same amount of force as you used to lift the full boxes. How will the acceleration of this box compare to the acceleration of a full box? Newtons second law of motion tells us that if the force remains constant and the mass is decreased, the object will accelerate at a faster rate.
