Let,
Dominant trait, red color be designated as C'C'
Recessive trait, white color be represented as C"C"
The F₁ generation of the cross :
C'C' X C"C" = C'C"
F₂ generation cross is shown in the image attached.
According to the cross, the probability of pink flower being produces 1s 50%
Answer is D. Timothy will lack testosterone and will probably be unable to achieve an erection
The point at which the toxin would interrupt normal cell signalling in the pathway is the signal amplification.
This is because of the G-protein uncoupling and inhibition of signal amplification by pertusis toxin. Pertusis toxin released by the bacteria Bordetella pertusis and prevents signal that is amplifying from the protein. The G-protein coordinates the interaction between membrane bound receptor proteins and the effector proteins involved in the intracellular signalling. The toxin promotes the uncoupling of this heterotrimetric protein and also inhibits the amplification thus preventing the interaction of the receptor proteins and the second messengers.
All liquid glow products depend on a chemical process known as CHEMILUMINESCENCE to produce their light. ... When the stick bends, the glass vial breaks allowing the two liquids to mix together. The chemical reaction begins immediately resulting in a bright, fantastic glow.
