Answer: i tried this is hard
Explanation:
Answer:
high pressure to low pressure
Explanation:
When warm air rises, cooler air will oftenmove in to replace it, so wind often moves from areas where it's colder to areas where it's warmer. The greater the difference between the high and low pressure or the shorter the distance between the high and low pressureareas, the faster the wind will blow
D. it is breathed out of the body by the lungs
It then enters the atmosphere and can be used by plants in photosynthesis to produce oxygen and glucose. Hope this helped :) if it did, please let me know by marking this answer as "brainliest!"
Answer:
When comparing homologous structures, we are comparing the anatomy of one part of an organism to another and finding it to be structurally similar but functionally may be different. Let’s compare a couple of tetrapods, specifically a human arm and a cat arm.
Both the human arm and the cat arm have a single bone in the upper arm, which we call the humerus, followed by two bones in the forearm–the radius on the more medial side and the ulna on the more lateral side. Both arms also have a common wrist structure followed by a grouping of metacarpals and phalanges. All of these structures are similar; however, these structures do not have the same function. Cats are quadrupeds that use their arms for walking and maybe a little climbing and hunting for outdoor cats. Humans, on the other hand, use their arms and hands for gross motor movement like grabbing, hugging, and lifting, as well as fine motor movement like using tools or even communicating.
A whale flipper and a bat wing are also homologous structures in the same sense as a human arm and cat arm with a humerus, radius and ulna, and so on. But the whale’s “arm” is actually a flipper that it uses to swim while the bat uses its wing to fly.
Our circulatory system is a complex network of blood vessels that carry blood from the heart to all parts of the body and back to the heart.
In doing so, the circulatory system provides all cells with the oxygen and nutrients they need, and removes waste and toxins. In addition to normalizing the temperature and pH of the body, the blood supply helps to heal any injury or injury.
Cardiovascular disease is the leading cause of death in the world according to WHO. So it's important to take care of our circulatory system, arteries and bloodstream to prevent diseases such as stroke, high blood pressure, arrhythmia or phlebitis.
Poor arterial circulation can be the result of narrowing or blockage of the arteries. In the Western world, the main cause of such deficiency is the accumulation of cholesterol within the arterial walls, which impairs the movement of blood flow.
If you have poor venous circulation, your veins will have trouble returning blood from the bottom of your body, especially the legs, to your heart. The blood will then tend to accumulate in your veins, which can lead to the formation of varicose veins.
