The speed of a sound wave depends upon the medium through which it travels. In general, sound travels faster through solids than through liquids or gases. Also, the denser the medium, the slower sound will travel through it. The same sound will travel at a different speed on a cold day than it would on a warm day.
Answer:
D. Be eliminated
Explanation:
Competition in biology is the process of interaction between two or more organisms, which are using the same resources e.g food, space, mate or occupying the same ecological niche. Competition between organisms often result in one or bother organisms getting harmed due to the strive for a limited resource.
Hence, in the case of two warblers occupying the same habitat and feeding on the same prey, competition is inevitable between these two species of organism. Therefore, the competition will eventually cause one of the species to be eliminated or killed.
In the stomach, food undergoes chemical and mechanical digestion. Peristaltic contractions (mechanical digestion) churn the bolus, which mixes with strong digestive juices that the stomach lining cells secrete (chemical digestion). As food travels from your mouth into your digestive system, it's broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion.
