What are the wavelengths of the mean echolocation clicks of bottlenose dolphins and killer whales? Remember, these echolocation

clicks are measured in kilohertz!

Echolocation is also called bio sonar. It is the sonar used by several kinds of animals that <span>enables them to locate and discriminate objects by projecting high-frequency sound waves and listening for echoes as the sound waves reflect off objects. </span>
Dolphins and whales make these sounds at any time and at considerable depths. Sounds vary in volume, wavelength, frequency, and pattern.
The wavelength depends on the speed of propagation (c).wavelength=c/f The speed of sound in water is c= 1450 m/s. 
So, for bottlenose delphins the wavelength is:1450m/s /  110.5 kHz
1450 m/s /  110500 Hz =0.013 m = 0.13 mm
For whales  the waveleng42.5 th is:1450m/s /  42.5 kHz = 
1450m/s /  42500 Hz= 0.034 m = 0.34 mm

The name given to media which allow different types of microbes to grow but are designed to display visible morphological or che
saveliy_v [14]

Given what we know, we can confirm that the type of media which allows the growth of different microbes while still being able to distinguish between them is called a differential media.

<h3>What is a differential media?</h3>
  • It is a type of media that allows for the growth of many different microbe types.
  • This media is special in that it allows the user to still distinguish between the microbes.
  • This is done primarily on a basis of the biochemical differences between the microbes.

Therefore, we can confirm that a differential media is a type of media that allows the growth of different microbes while still being able to distinguish between them, focusing on biochemical differences of the two colonies grown.

Which of the following reproduces by injecting its genetic material into a host cell ?
jarptica [38.1K]

Answer:

B. Virus

Explanation:

Once attached to a host cell, a virus injects its nucleic acid into the cell. The nucleic acid takes over the normal operation of the host cell and the host cell produces multiple copies of the virus.

A patient has a large bruise so the phlebotomist collects a blood specimen distal to it. describe where the specimen was collect
olga55 [171]

Phlebotomy refers to a collection of venous blood. This operation can be practiced on all the superficial veins of the body, on those of the foot, the leg, the neck, the whole upper limb. It must be done in an area where there is a protruding vein and the least sensitive to limit pain to the patient. It should not be done in an altered, injured or infected area (like bruise)

The blood is collected on tubes with or without anticoagulant according to the analyzes that one wants to practice.

The reason for choosing the sampling site is for the most part practical, the veins are easily identifiable, and easily accessible for paramedical personnel. Their collection is less dangerous than that of arteries, which are generally thinner and close to the peripheral nerves.
