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.
Every action has an equal and opposite reaction. I would assume that the energy in the other direction would be an action.. though I'm not entirely sure. I hope it helps.
False the process is reversed. Photosystem ll happens before photosystem l. I know that's weird but it's true. In photosystem ll which happens first it makes the energy carriers for ATP Synthase to happen in Photosystem l which is the next phase. Hope this helped!
Answer: The correct option is D(Some produce toxic agents in the water).
Explanation:
Dinoflagellates are found in the phylum Dinoflagellata which are single celled organisms. They are mostly found in the ocean while few of them can live in streams, freshwater ponds and rivers. The following characteristics can be used to identify a Dinoflagellates, these include:
--> they are golden brown
--> they possess assimilative cell with indented waist.
--> they possess large nucleus with visible chromosomes.
It has been reported that many dinoflagellate species can produce various natural toxins. These toxins can be extremely toxic and many of them are effective at far lower dosages than conventional chemical agents. Therefore the option, Some produce toxic agents in the water, is a correct statement.
