Answer: The receptors are highly specific.
Explanation: yes
Answer:
The proportion of the genotypic recombinants among the offspring from this cross is 75%
Explanation:
Separating the alleles from the parents independently, We have AB, Ab, aB, and ab.
These should be crossed using punnet's square, we will therefore get the genotypic of the 16 progenies as: AABB, AABb, AaBB, AABb, AAbb, AaBb, AaBB, AaBb, aaBB, AaBb, Aabb, aaBb, aabb, aaBb, Aaaa and AaBb. From these, only those in bold retained the genotype of their heterozygous parents. Therefore, 12 out of 16 are genetic recombinant, which are the offspring that differs from their parents after a cross. This made the proportion to be 12/16 X 100 = 75%.
Explanation:
because the scene should be realistic to watch, that's all
Answer;
Electron microscope
Explanation;
-Electron microscopes focuses beams of electrons on specimens, they produce images by focusing beams of electrons.
-They utilize the same principles behind an optical microscope, but rather than photons or particles of light, concentrate electrons, charged particles located on the outside of atoms, onto an object.
-They focus the electron beam using electromagnetic coils instead of glass lenses (as a light microscope does) because electrons can't pass through glass. There are two types of electron microscope; scanning electron microscopes (SEM) and transmission electron microscopes (TEM).
It was not until 1953 that James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin figured out the structure of DNA — a double helix — which they realized could carry biological information
