Answer:
Option A, Key stone
Explanation:
A keystone species plays a major role in an ecosystem as it is the species whose presence effects all other species in the ecosystem .In general a keystone species is always a dominant predator that feed on prey population. If it is removed, the prey population will explode and the population diversity will reduce. For example - bison, prairie dog etc.
Hence, option A is correct
Honestly, this is supposed to be your opinion, but I will give you mine. I think there should by far be a quality standard, that they should always provide good quality things. It all just depends on what kind of standard they are talking about or what the question is referring to. If there are experiments going on, there should definitely be a certain standard of safety and ensure that the person would come out alive. I hope that this could help a bit, and I apologize if this was not the type of standard in which you were looking for. If you need further help, you can send a DM my way and I will respond when I get the chance. Have an amazing day!
Answer:
Delta binds to the Notch receptor and this binding produces the cleavage of its intracellular domain, which subsequently enters into the cell nucleus to bind with a repressor in order to activate the transcription
Explanation:
The Notch signaling pathway is initiated when Notch receptors on the cell surface bind to the Delta ligand, which activates Notch signaling in cells next to it. In the receiving cell, Delta–Notch binding triggers the cleavage of the Notch intracellular domain called Nic (intracellular Notch). Subsequently, Nic enters into the cell nucleus where it releases repression on Suppressor of Hairless (Su(H)) class transcription factors, thereby activating the transcription of target genes.
