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.

<h2><u>Answer:</u></h2><h3><u>Question 1:</u></h3>
The correct option is A (a curved path)
Explanation:
Their way is diverted by the revolution of the earth. This is the Coriolis impact. This is the motivation behind why wind streams on the northern side (north half of the globe) turn counter-clockwise and that blows south of the equator, the southern side of the equator, turn clockwise.
<h3><u>Question 2:</u></h3>
The correct option is B (forms at or near the ground)
Explanation:
Fog is an obvious vaporized comprising of modest water beads or ice precious stones suspended noticeable all around at or close to the Earth's surface.
Haze can be viewed as a sort of low-lying cloud, more often than not taking after stratus, and is vigorously impacted by adjacent waterways, geology, and wind conditions.
