Light is a form of EM radiation.
EM radiation has no mass (it's just energy packets called photons).
EM radiation can travel through a vacuum. (The speed of light in a vacuum is called c and is around 300,000 m/s).
Hope this helps!
Telophase 2 is the final step of meiosis 2 in which homologous chromosomes reach the opposite poles and four haploid cells are formed.
Explanation:
The telophase 2 ends up in four haploid (n=2) cells. It is in this phase the genetic material of the parent cell is divided into 2 daughter cells. The events taking place are nuclear membrane reappears (karyokinesis has taken place by now), spindle fibres and astral rays disappear, chromosomes decondensed to become chromatids (thin fibres), constriction on equatorial plate consequently four daughter cells formed.
Answer:
It accelerates the production of a second messenger.
Explanation:
Adenylyl cyclase is an enzyme capable of converting ATP molecules into cyclic adenosine monophosphate AMP (cAMP). The cAMP molecule is considered to be a second messenger that transfers the hormonal signal (i.e., epinephrine) inside the cell. Subsequently, cAMP activates molecular signaling events by binding and thus activating cAMP-dependent protein kinase A (PKA). Finally, this last protein (PKA) phosphorylates different proteins that control many diverse cellular processes.
