Answer: microorganisms
Explanation: No animal has the ability to digest cellulose directly.
Most animals such as horses and termites cannot directly digest cellulose. The animals have a symbiotic relationship with bacteria in the intestinal tract. The symbiotic bacteria acts on the cellulose and secrets the necessary enzymes (cellulase) to digest cellulose in the intestinal tract. An example of such microorganism in a symbiotic relationship with animals that facilitates the digestion of cellulose is Trichonympha
Answer:
Question: Two requirements for gas exchange which are accomplished by the gills in a fish include:
1. Water flowing in opposite directions across the gill lamellae for gas exchange, in other words, respiration is experienced by the fish.
2. The fish allows water through its mouth, then forces the water to drain through the gills supporting gill lamellae, and enhancing gas exchange.
Question: How does their structure help to satisfy these requirements?
1. The rows of gill filaments with numerous folds through diffusion makes sure oxygen from the water moves from a place of more concentration to the blood of the fish which has less concentration causing the removal of carbon dioxide.
2. The large surface area of the gill means it has to maximize the low percentage of dissolved oxygen in the water compared to the higher percentage of oxygen in the air makes it possible for water to pass through the mouth and empty through the gills after the mouth is closed.
D) is the correct answer bc the question states that all water on earth is apart of the water cycle, if the water was on a different planet then we'd have a problem lol.
Answer:
Letter b. Gluconeogenesis
Explanation:
Immediately after eating we use the sugars in the food and utilize for energy and last a couple of hours. After that and about 15 hours later our body uses the energy stored in the liver in the form of glycogen, a process called glycogenolysis, that is the action of breaking the glycogen to free the energy. After 24 hours, the body starts to use another molecule for energy like fatty acids and start to synthesize glucose from other precursors, this process is called gluconeogenesis, and fuels the vital organs like the brain to maintain its function.
