<h2>Answer:</h2>
Option B, the diver will hear the sound first.
<h2>Explanation:</h2>
Sound need a medium to travel from one place to another, the medium where atoms are more closely packed together, the better will be speed of sound. That is why sound won’t travel in a vacuum because there are no particles to bump together to transmit the vibration.
- In air, the particles are generally far from each other so they travel further before they bump into one another.
- In water, the particles are much closer together, and they can quickly transmit vibration energy from one particle to the next. This means that the sound wave travels over four times faster than it would in air.
Genetically identical to the parent cell
Answer:
Explanation:
high muscle capillary density means a large muscle-to-blood exchange surface area, short oxygen diffusion distance, and high red blood cell mean transit time.Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.
In humans, the maintenance of a stable internal temperature is a direct result of Homeostasis. Homeostasis is the ability of the body to maintain an equilibrium condition within it's internal environment even when dealing external changes. Homeostasis happens in human when there is an effort exerts by the body to regulate it's internal temperature around 98.6 degrees Fahrenheit. For example, during summer days we produce sweat for our body to cool off, and during winter we shiver for our body to produce heat.
None of those options are correct.
Fungi produce,naturally, antibiotics that will kill or inhibit the growth of bacteria.
This is useful for them to limit competition in their natural environment but it's also useful for us because it will kill bacteria that cause us infections.
The only thing scientists had to do is isolate that antibiotic.
Some antibiotics that were developed from fungi: penicillin and cephalosporins.
