The interaction between two polar molecules would involve HYDROGEN BONDS.
Polar molecules are molecules that have both positive and negative charges as a result of the differences in the electronegativity of the atoms that made up the molecule. Polar molecules interact through dipole dipole inter molecular forces and hydrogen bonds.
Answer:
Steroid hormones that enter the cell activate receptors. These hormone-receptor complexes then bind HREs and influence gene expression.
Explanation:
Mechanism of action of steroid hormones is as follows:
- Steroid hormone enters cell and bind to the receptor.
- Translocation of activated receptor- ligand complex into nucleus.
- This complex then bind to another receptor on the chromatin.
- Steroid receptors form dimers.
- Act on DNA
- These hormone-receptor complexes then bind HREs and influence gene expression.
- Augmentation or Suppression of transcription.
Answer:
1. Option A
2. 56
Explanation:
1.
Option A
Option A is not a valid answer for this question as it is given that out of eight rats only two rats are untrained. Thus, an output which shows more that two untrained rats i.s UUTTU is a wrong answer
2.
Thus , there are 56 outcomes possible for this experiment
