Answer:
alfa, beta and gamma
Explanation:
Rutherford studied the three types of radiation.c In the case of alpha radiation, it is composed of two protons and two neutrons, the alpha particle is a nucleus of the element helium, which has high mass and short range.
In the case of beta radiation, it travels distances of up to one meter and consists mainly of electrons.
In the case of gamma radiation, it is composed of high-energy photons (it does not have my electrical charge or resting mass).
This is called light-dependent reacation
Answer:
4. c) They result in production of diffusible second messengers
Explanation:
G-protein coupled receptors (GPCR) and steroid hormone receptors have common in the way that both result in the production of diffusible second messengers into the cytosol for further initiation of signal transduction pathways in the target cell. Hence option (c) is the correct answer.
