A researcher observing an ecosystem describes the amount of sunlight, precipitation, and type of soil present. The researcher is most likely describing abiotic factors in a prairie.
A and B are incorrect because the factors described are abiotic, not biotic.
Di is incorrect because abiotic factors listed include soil, which is not likely to be described in an ocean environment.
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.
<span>An amphibian that lacks lungs and breathes entirely through its skin would have to be smaller than an amphibian with lungs so that the small oxygen intake correlates with
the small surface area of the amphibian. This would then allow it to breath efficiently.</span>
Answer:
% GENOTYPE
FF = 0%
Ff = 50%
ff = 50%
% PHENOTYPE
Black fur = 50%
Grey fur = 60%
Explanation:
This question involves a single gene coding for fur color in dogs. The allele for grey fur (F) is dominant over the allele for black fur (f). This means that a heterozygous dog (Ff) will have a grey fur.
In this question, a heterozygous female (Ff) is said to cross with a recessive male (ff) i.e. Ff × ff. The following gametes will be produced by each parent:
Ff - F and f
ff - f and f
Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced:
Ff - 1/2 = 50%
ff - 1/2 = 50%
Ff is phenotypically GREY while ff is phenotypically BLACK. This means that 50% of the offsprings will be black and 50% will be grey.
