Answer:

Female salmons create the hole where eggs are laid and fertilized by male sperm cells.

Explanation:

Salmon are fishes which live in salt water oceans and fresh water streams. They return to their home stream and lay their eggs at the bottom of the stream by digging it. This is usually done by The female salmon turning on her side and beating the river bed with powerful sweeps of her tail. She does this until the hole is a foot and a half deep. She then lays the egg there which is then fertilized with speed by the male.

She then dies in the same place in which she was born about 5 years earlier.

Feliz [49]

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.
