is the coldest place on earth.
Explanation:
The differentiation is based on a set of activation / inactivation of genes (parts of DNA) via complex cascades of regulation. We can not consider a differentiating cell individually. Indeed, its "expression profile" depends on its environment: cell-cell interactions, cell-matrix. It is these extra-cellular signals that will trigger the internal regulation signals. The establishment of plans for the organization of a Drosophila embryo or the development of limb buds in mice are well-known models. In these models, so-called "positional" information plays a large role: a substance present in the form of a concentration gradient in the extracellular medium will trigger or not intracellular signals depending on the dose at which the cells are exposed along this gradient.
It is this scattered light that gives the surrounding sky its brightness and its color. As previously stated, Rayleigh scattering is inversely proportional to the fourth power of wavelength, so that shorter wavelength violet and blue light will scatter more than the longer wavelengths (yellow and especially red light).
Answer:
C. 100 percent
Explanation:
The woman is heterozygote: AO, while the man is homozygote: BB
By crossing the two:
AO x BB
A+B, A+B, O+B, O+B
AB, AB, OB, OB
We have two AB and two OB offspring. Both AB and OB are heterozygotes.
Thus all their offspring will be heterozygous.
<em>Had the question asked what proportion will be OB, the answer would have been 50%.</em>
Since the question asked, what proportion will be heterozygotes and not about the specific genotype, the correct answer is C. 100 percent
