The right option is; Segregation
The diagram represents the Mendel’s law of segregation.
The law of segregation is one of the principles of heredity discovered by Gregor Mendel. Mendel's law of segregation states that all organisms possess two pairs of alleles for each trait and that these alleles seperate during meiosis in a such a way that each gamete have only one pair of the alleles. The law explains that when an organism produces gametes, one gene copy is distributed to each of the gametes and that the selection of the gene copies is random.
If we name the gene for pods with A, than the alleles are: A-dominant, a-recessive.
The possible genotypes for the smooth pods are: Aa and AA, while genotype for constricted pods is aa.
If one parent has constricted pods and the other parent is homozygous for smooth pods there are two possible combinations:
P: AA x aa
F1: Aa Aa Aa Aa all of the offspring are constricted
Another combination:
P: Aa x aa
F1: Aa Aa aa aa half of the offspring are with constricted pods and half with smooth pods.
So, the correct answers are:
• all of the offspring will have constricted pods
• 50% of the offspring will have constricted pods and 50% will have smooth pods.

Answer:
Enzyme-linked
Explanation:
The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).
Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.
