Fossils are physical evidence of preexisting organisms, either plant or animal. ... Fossils of any kind are useful in "reading the rock record," meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited.

A heterozygous, three-horned alien from Mercury has met and fallen in love with a four-horned alien from Jupiter. What would hap
Gnesinka [82]
Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen.  If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!

A particularly long radio wave has a wavelength of 1.5 x 10^9 meters. What is the frequency of this radio wave?
Phoenix [80]

Answer:

0.2Hz

Explanation:

The wavelength of a radiowave can be calculated this;

λ = v/f

Where;

λ = Wavelength (m)

v = speed (m/s)

f = frequency (Hz)

Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?

Hence, using λ = v/f

f = v/λ

f = 3 × 10^8 ÷ 1.5 x 10^9

f = 2 × 10^(8-9)

f = 2 × 10^-1

f = 0.2Hz
