What are the wavelengths of the mean echolocation clicks of bottlenose dolphins and killer whales? Remember, these echolocation
harkovskaia [24]
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

place the following categories in order from most specufic to least specific. A) bryophyte B) seedless plant C) eukaryote D) mos
Genrish500 [490]

Answer:

 C) eukaryote A) bryophyte  D) moss​ B) seedless plant

Explanation:

According to Whittaker five kingdom classification, the most specific classification includes prokaryotes and eukaryotes . Unicellular organisms were placed under Monera whereas Multicellular organisms were placed under Eukaryotes. Based on the cell wall, Eukaryotes were further divided into plantae and animalia. Plantae includes Thallophytes, Bryophytes (lacks differentiation of stem, leaf and root), Pteridophytes (seedless vascular plants), Gymnosperms (naked seeds) and angiosperms (Flowering and non- flowering plants).

What kind of atoms typically have unstable nuclei?
nikklg [1K]

B & D

Protons and neutrons are energy particles found in the nucleus of atoms.

Explanation:

The forces that hold the protons and neutrons together in the nucleus are called strong nuclear forces. These forces are attractive over short distances and repulsive over long distances. This is why protons that are positively charged are held together in the nucleus  despite their repulsive tendencies. However, as the nucleus gets larger because of the larger number of protons and neutrons in the nucleus, the distance with which the string nuclear forces are attractive is surpassed.

The binding energy in the nucleus will, therefore, be surpassed by the repulsive forces of strong nuclear forces over long distances causing the atomic nucleus to lose some neutrons.
