The answer is <span>Conduct a test cross with a purebred recessive plant.
</span>
Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.
<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>
If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.
<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>
As white light passes through a prism, the light is separated into the different colours of light that we see and this is called the visible spectrum. Each colour of light has a different wavelength. The wavelength is inversely proportional to the energy of that light. As the wavelength increases, the energy decreases and vice-versa. The relationship is:
E = h/λ, E is energy, h is Planck's constant, and λ is the wavelength.
Therefore, the answer is B) different amounts of energy in white light.
Answer:

chemical transmitters are the language that neurons use to connect eachother.
Answer: thylakoid membrane
Explanation:
Answer: D. None of the above
Explanation:
Heredity can be defined as a biological process that involves the passing on of characters or traits from parents to their offsprings genetically. These traits can be physical for example, height, colour of eyes or mental for example, intelligence.
