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.
The correct sequence of events that occur during the cell growth and reproductive process or cell cycle would involve that cytokinesis which involves splitting or separating of the cytoplasmic media connecting the cells together to produce 2 new cells that have the same genetic content, occurs after Mitosis.
The correct response would be C. Cytokinesis follows mitosis.

Fungi release enzymes which in turn help in digesting external material. Then the fungi absorb that digested compound that is created by the enzyme. Plants normally make their own food by the process of photosynthesis. Plants take in water through the roots from the ground, absorb sunlight during the day and take in carbon dioxide from the air to make their nutrients. So plants are normally autotrophic in nature. Animals on the other hand consume plants as well as other animals to produce nutrients. So animals are mostly heterotrophic in nature.
Answer:
The haploid structure of the plant, during a stage in plant's life cycle, is known as the <u>gametophyte.</u>
Explanation:
The life cycle of plants includes a haploid generation and a diploid generation. Both the structures are multicellular.
The diploid structure of a plant is known as sporophyte. This structure produces spores via meiotic division.
Whereas, the haploid structure of the plant, known as the gametophyte, is formed from spore and produces haploid gametes.
