Some birds prioritize blending in with their environment while other species of birds have bright and effervescent feathers in order to attract a mate.
Hope this helps!
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
DNA, Deoxyribonucleic acid. DNA is the empirical proof of God.
DNA can never be created naturalistically and is absolutely uniquely structured:
1. DNA contains multiple levels of coded organically constructed information that controls all cellular functions and no natural process is capable of creating or coding.
2. The amino acids that provide the coding fo the genetic information are homochiral. The few, not all, amino acids that can form naturally are not symmetric and are either left-handed or right-handed, called racemic. All amino acids in DNA, RNA, proteins, enzymes, ribosomes and other cellular assemblies are left-handed, 100%. No right-handed amino acid can function within DNA. Nature may produce a partial list of racemic amino acids, but cannot produce homochiral amino acids, again, only produced within a cell.
3. Phosphate penta-sugars provide the overall dual backplane physical structure to allow the amino acids to be affixed and are all right-handed homochiral, not produced in nature and exclusively right-handed.
There are exactly 24 chromosomes in a girl cell and 24 in a boy cell.
