Answer:
See explanation
Explanation:
Darwin proposed his theory of evolution on the premise of natural selection. According to him, organisms which possess favourable characteristics which enable them to survive in their environment are more likely to survive and reproduce, passing on these favourable characteristics to their offsprings.
According to Mendel, the unit of inheritance passed on from parents to offspring are genes. Hence Darwin's factors are Mendel's genes.
If Darwin knew of Mendel's work. It might have influenced his presentation of the idea of passing on favourable characteristics from parents to offspring in the light of genetics.
This would have made Darwin's work to have more empirical backing hence making it more widely accepted.
We need carrier proteins for steroid hormones because they help in the transportation from the cell they were released from to their target cell.

All mentioned complexes (receptor-hormone, antibody-antigen, enzyme-substate) are involved in a molecular recognition.The molecular recognition involves <span>non-covalent </span> interaction between molecules. To form complex, molecules must be complementary in shape and charges, and usually, they are compared to key and lock. This way, the selectivity and specificity of recognition between molecules are assured.
