Assuming this is multiple choice, the answer would be "niche". An organism's niche is where that certain organism fits into an ecosystem, or what their part to play is.
Answer:
There are two types of cell division Mitosis and Meiosis
a cell divides to form diploid gametes during mitosis and haploid during meiosis
Answer:
1. Ends of the respiratory branches are called alveoli.
2. C. To control blood flow to different areas of the body depending on activities
Explanation:
1. The trachea divides into left and right primary bronchi which in turn divide multiple times upon entering the lungs and make the bronchial tree.
The final branches of the bronchial tree are the terminal bronchioles that lead to alveoli. The alveoli are the balloon-shaped structures and serve as the site of gas exchange between the blood and inhaled air.
2. The opening and closing of sphincters of capillary beds regulate the direction of blood flow. The opening of sphincters allows the blood to flow into associated branches of capillary beds while closed sphincters direct the blood from arterioles to venules via thoroughfare channel.
This local change in blood flow is responsible for the autoregulation of blood flow to different tissues to match their respective metabolic demands. For example, during physical activity, more blood is directed to skeletal and cardiac muscles.
Answer:
The answer is The pressure of gas in your lungs is inversely proportional to the volume in your lungs.
Explanation:
Because Boyle's law describes how air moves in and out of your lungs during inspiration and expiration. By the changing the volume inside the thoracic cavity, the pressure changes in the lungs. Increasing volume of thoracic cavity leads to a decreased pressure, causing air to flow into the lungs, down its pressure gradient and thus causing inspiration.
