The respiratory systems of birds are very efficient at providing oxygen to the blood, which is necessary for birds to expend the energy necessary to fly. What feature of the bird respiratory system makes it more efficient than the respiratory systems of other animals?
Answer:
In birds, air flows through the lungs in a unidirectional manner through a bronchial system that is made up of primary bronchi, secondary bronchi, and tertiary bronchi called parabronchi, which are the functional units of gas exchange.
Explanation:
The respiratory system of birds has peculiar characteristics both in its structure and in the way its breathing is carried out. The respiratory system of birds is made up of the lungs, air sacs, trachea, bronchi, blood vessels and nerves. Compared to mammals, birds lack structures such as the ethmoid labyrinth and the thoracic cavity is not limited by the diaphragm. When the bird breathes in, the air is drawn directly from the bronchi to the posterior air sacs, where the air is stored. As the posterior air sacs expire they deflate, this causes the air to pass into the lungs, where oxygen is absorbed. The consumed air (which contains carbon dioxide harmful to the organism) is then lodged in the anterior air sacs, and the animal inhales fresh air again to send to the posterior air sacs. After exhaling the consumed air expelled from the anterior sacs (to the outside) and bringing fresh air from the posterior air sacs to the lungs. This dynamic in the respiratory system of birds, allows air movements unidirectionally through the lungs generating a higher oxygen content.

"Living things are found in their habitats. They interact with each other and their environment. This interaction is between biotic and abiotic factors."
Answer:
TRUE
Explanation:
All living beings that is found in the nature interacts with each other and with the nature and their surroundings. They are always found in their habitats. Different organism living in the biospheres interacts and adapts with each other and to their environment. Such study of interaction of organisms with their environment is called ecology. These interaction is always between the biotic factors and abiotic factors.
The biological influences of the living organisms when they react with the living part of the surrounding or the environment are called biotic factors. While interaction with the non living parts like soil, sunlight, wind,water, etc are called abiotic factors.

the dialysis tube was permeable to which substance? how did you determine this?
Answer:
It was concluded that the dialysis tubing doesn't allow all kinds of substances to pass readily through the pores of its membrane. This means that it is selective in its permeability to substances. The dialysis tubing was permeable to glucose and iodine but not to starch.
Explanation:
The dialysis tubing is selectively permeable because substances together with water, glucose, and iodine were able to pass through the tubing but the starch molecule becomes too big to skip. 3. Sucrose is a disaccharide and therefore much large than the glucose, a monosaccharide, that becomes used within the experiment.
How could you tell the dialysis tubing turned permeable to the iodine?This could be regarded from the color alternate within the answers within the beaker and the bag. The tubing became permeable to iodine and so the content of the bag became blue-black in color indicating the presence of starch. Glucose is also readily handed through the pores of the membrane.
Which materials crossed the dialysis membrane?The dialysis membrane is one of the essential components that determine dialysis overall performance. these membranes permit only low-molecular-weight molecules, consisting of sodium, potassium, urea, and creatinine, to skip through even as blocking proteins, along with albumin, and different large molecules.

During cellular respiration, the covalent bonds of a molecule are broken down to form products. Which molecule is broken down?
O water
O carbon dioxide
sugar
O ADP
Answer:
sugar C ;D
Explanation:
Sugar is the molecule that is broken down during cellular respiration.
Glucose is a relatively large molecule and contains more energy in its bonds than smaller molecules. Therefore, by breaking it, energy is released that the body can use to perform its vital functions.
This breakdown occurs in cellular respiration, which is a catabolic process in which a fuel molecule, glucose (sugar), whose energy is trapped in the form of ATP (universal source of energy), is oxidized.
Glucose is oxidized and degraded to carbon dioxide and water, producing ATP.
The production of energy in the form of ATP generates heat, so ATP cannot be released all at once, but must occur gradually, in several stages: glycolysis, Krebs cycle and oxidative phosphorylation.
Therefore, we can conclude that sugar, which is the molecule that initiates respiration, is the molecule that is broken down during cellular respiration, which releases the energy stored in the chemical bonds of glucose.

What is the greatest source of canton that enters the ocean from the atmosphere ?
Answer:
Carbon is an element that is essential to all life on Earth. Carbon makes up the fats and carbohydrates of our food and is part of the molecules, like DNA and protein, that make up our bodies. Carbon, in the form of carbon dioxide, is even a part of the air we breathe. It is also stored in places like the ocean, rocks, fossil fuels, and plants.
The carbon cycle describes the flow of carbon between each of these places. For example, carbon continually flows in and out of the atmosphere and also living things. As plants photosynthesize, they absorb carbon dioxide from the atmosphere. When plants die, the carbon goes into the soil, and microbes can release the carbon back into the atmosphere through decomposition.
Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis. The ocean is another example of a carbon sink, absorbing a large amount of carbon dioxide from the atmosphere.
Some processes release more carbon dioxide into the atmosphere than they absorb. Any process that uses fossil fuels—such as burning coal to make electricity—releases a lot of carbon into the atmosphere. Raising cattle for food also releases a lot of carbon into the atmosphere. These processes that release carbon into the atmosphere are known as carbon sources.
Ideally, the carbon cycle would keep Earth’s carbon concentrations in balance, moving the carbon from place to place and keeping atmospheric carbon dioxide levels steady. However, the carbon cycle is changing because of human activity. People are releasing more carbon into the atmosphere by using fossil fuels and maintaining large livestock operations. Deforestation is depleting Earth’s supply of carbon sinks. As a result, the amount of carbon in the atmosphere is rising.
