A very large star of high luminosity and low surface temperature. Red giants are thought to be in a late stage of evolution when no hydrogen remains in the core to fuel nuclear fusion.
C. Law of segregation is the Mendel's law that states that gametes carry one allele for each trait.
I think its A. If you had options like mine
Answer:
Photons
Explanation:
The retina is a thin layer (membrane) in the eye that receives light through photoreceptor cells that convert this light into chemical and nervous signals transported to the brain's visual center.
The photoreceptors in the retina are known as rods and cones. Rods detect motion and sare responsible for black and white vision, they are present in the macula. Cones on the other and, are responsible for central and color vision. <em>These photoreceptors absorb photons that trigger the membrane's potential of the cells.</em>

Well Water is essential to life for a number of reasons. It is a useful solvent that exists as a liquid at the ideal range of temperatures for life as we know it on Earth, behaving as a perfect medium across which biochemical reactions can occur. Your cells transport resources across the spaces within and between them facilitated by this medium, just as your blood serves as the ideal medium for transporting oxygen-carrying corpuscles and a rich soup of nutrients, hormones, and even waste products being sent for filtration. The very structure of your tissues is reliant upon water content; consider the difference between a fresh loaf of bread and a stale (dry)one that can be crumbled between the fingers. Plant cells, just like animals cells, require hydration to function, too. In fact, right down to unicellular life forms, life as we know it on this planet relies upon water existing as a liquid in order to function on a <span>biochemical level. I hope that helps you.</span>
