Explain why visible structures, such as fins, beaks, and tails, look so different on different organisms.
well, different species have different features depending on where they live, and most often than not, species will evolve to fit their surroundings. Like, for instance, a bird's beak will evolve over time and grow longer to reach the pollen from longer a longer flower. Some species may have tails to help them move because they might not have the balance or fins to help them swim because they live in water. Land animals wouldn't really need fins.
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.
What two recurring events in earth history have impact on the carbon cycle
Answer:
Answer:
a. Earth’s orbit and climate change
Explanation:
Over the years, the carbon cycle has seen changes in response to climate change. The amount of energy has varied in comparison to the changes is the earth’s orbit. The development of ice ages has seen a slowdown in the carbon cycle.
Similarly, temperature variations and climate changes initiated by the burning of fossil fuels have deeply impacted the carbon cycle by increasing the ratio of carbon dioxide in the atmosphere causing global warming. Therefore, the earth’s orbit and climate change are two recurring events in the Earth’s history that have impacted the carbon cycle.

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.

Which parts of the body are considered part of the alimentary canal?
Answer:
The mouth, pharynx, esophagus, stomach, small intestine, and large intestine.
Explanation:
HOW DO I KNOW THIS IM ONLY IN 6TH GRADE
Answer:
Oral Cavity, Oesophagus, Stomach, and Small intestine
Explanation:
Parts of the body are considered part of the alimentary canal are Oral Cavity, Oesophagus, Stomach, and Small intestine because the Oral Cavity includes the lips, the inside lining of the lips and cheeks (buccal mucosa), the teeth, the gums, the front two-thirds of the tongue, the floor of the mouth, below the tongue, and the bony roof of the mouth (hard palate).
The Oesophagus connects the throat to the stomach; which is the gullet. In humans and other vertebrates it is a muscular tube lined with mucous membrane.
The stomach is located between the esophagus and the small intestine. It secretes digestive enzymes and gastric acid to aid in food digestion. It is a muscular hollow organ in the gastrointestinal tract of humans and many other animals, including several invertebrates.
The Small intestine or small bowel is an organ in the gastrointestinal tract where most of the end absorption of nutrients and minerals from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pancreatic duct to aid in digestion.
