1. releases bile to break down fat lungs 2. helps break down protein small intestine 3. remove carbon dioxide from the body liver 4. breaks down starch into sugar large intestine 5. absorbs nutrients into the blood pancreas 6. absorbs extra water from undigested food saliva
Answer:
1. Liver
2. Pancreas
3. Lungs
4. Saliva
5. Small intestine
6. Large intestine
Explanation:
1. Liver is a large, infact the largest, organ found in the digestive system. It has variety of functions ranging from detoxification to digestion. The liver functions in digestion by secreting a substance called BILE which helps in the breakdown of fat in the small intestine.
2. Pancreas is another accessory digestive organ which serves as a endocrine organ which secretes enzymes that aid in the digestion of protein and carbohydrate molecules.
3. Lungs are respiratory organs whose function is key to the respiratory system. They are the organs that serve as a medium of the entry of oxygen and removal of carbon dioxide, a process called GAS EXCHANGE.
4. Saliva is a liquid substance secreted by the salivary gland in the mouth. Saliva contains certain enzymes; most notably is the AMYLASE that breaks down starch into sugar.
5. Small intestine is another organ in the digestive system composed of the ileum, jejenum and duodenum. The small intestine is the organ where the absorption of nutrients into the blood from the digested food takes place.
6. Large intestine is the extension of the small intestine whose function is to absorb extra water from undigested food and pass out the remaining as feaces.

Mr. Bailey decides to do an experiment to see if different types of popcorn pop faster in the
microwave. The TV commercials say that Popalicious is the fastest popping popcorn in the
world. Mr. Bailey's hypothesis was, "If I pop Jiffy Pop, Popalicious, and Pop-Tastic popcorn in a
microwave, then the Popalicious will pop faster because the commercial says so." He takes
Jiffy Pop, Popalicious, and Pop-Tastic and places them each in the microwave for 2 minutes.
After two minutes is up, he counts the number of POPPED kernels in the bag. After three trials,
Jiffy Pop had an average of 256 popped kernels, Popalicious had an average of 341 popped
kernels, and Pop-Tastic had an average of 357 popped kernels.

active transport pumps molecules and ions against their ___ gradient using atp
Active transport pumps molecules and ions against their concentration gradient using atp.
What is Active Transport?Active Transport is described as a process that involves the movement of molecules against a gradient or an obstruction from a location of lower concentration to a region of greater concentration." The steady variation in a solution's solute concentration as a function of distance is referred to as a concentration gradient. This mechanism is referred to as "active" transport since it uses energy.
The sodium-potassium pump is active transport since it moves sodium out of the cell and potassium in. The interior lining of the small intestine frequently hosts active transport.

While eating a piece of fruit, a group of scientists noticed that some had fruit that was spoiled while others didn't. One scientist said they left their fruit on the counter, another left theirs in the fridge, and one left theirs in the freezer. They decided to conduct an experiment to determine where fruit should be stored so it stays fresh longer. The fruit of choice was granny smith apples that were bought at the same time and were the same size. One apple was left on the counter, another in the fridge, one in the freezer, one was left outside on a porch, and a final apple was left in the microwave. All remained in their locations for one week and they tested which apple was freshest. In this experiment, what is the independent variable? A. Type of apple B. Where the apples were left C. Amount of time apples were left out D. Freshness of apple
Answer:
"where the apples were left"
Explanation:
In the scenario being described the independent variable would be "where the apples were left". This is because where the apple was left does not depend on any other factor for the results to be affected. The freshness of the apple would be the dependent variable because it depends on where the apple was left and for how long, while the amount of time is the controlled variable in this scenario because it remains constant for all groups and was chosen by the scientists.

Without the circulatory and respiratory systems, human bodies would not survive. Both systems play major roles in providing our bodies with what they need. They work individually as well as together to keep us alive and healthy,
Which statements describe functions of the circulatory system?
Part of this system filters air as it enters the body.
Oxygen is delivered to cells throughout the body by this system.
Nutrients are delivered to organs through this system.
This system takes in oxygen from air outside the body.
This system removes carbon dioxide from organs and delivers it the lungs.
Carbon dioxide exits the body through this system.
This system's organs passes oxygen into the bloodstream.
This system plays a major role in fighting infections.

The statements that describe the functions of the circulatory system are as follows:
Oxygen is delivered to cells throughout the body by this system.Nutrients are delivered to organs through this system.This system removes carbon dioxide from organs and delivers it to the lungs.This system plays a major role in fighting infections.What is the Circulatory system?The Circulatory system may be defined as a type of organ system that significantly involves the sequence of organs that togetherly work in order to circulate blood throughout the body. Examples of this organ system may include the heart, blood vessels, lymphatic vessels, and some glands.
According to the function of the circulatory system, it usually helps the body to fight against infections due to the role of white blood cells. The respiratory system significantly works along with the circulatory system in order to inhale atmospheric oxygen and exhale carbon dioxide through the lungs. But they are not the function of the circulatory system.
Therefore, the statements that describe the functions of the circulatory system are well described above.

2. How do cells produce new cells for growth and repair?
Answer:
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.
Explanation:
Answer:
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. ... Some organisms can use mitosis to reproduce asexually. The offspring of asexual reproduction are genetically identical to each other and to their parent.
Cells make copies by dividing into two cells in a process called mitosis. As the parent cell divides, it passes on its genetic instructions to both copies. The new cells look and function just like the parent. Eventually, each of the new cells will divide, too.
Dead cells can make new cells in order to grow and also to replace old dead cells. The process by which new cells are made is called cell division.
