Answer:
a. The alpha-carbon
Explanation:
An amino acid is an organic molecule that contains a carboxyl (COOH) and a amino (NH2) group. It has a central carbon called as alpha carbon.
The carboxyl and amino groups are attached to the the alpha carbon. Apart from them, a side chain denoted by "R" is also covalently attached to it. Side chain varies in each amino acid and it imparts the unique properties to the particular amino acid.
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.

6) the moon doesn't have it's own light- so it shines because it's reflecting the sunlight which creates a red moon affect during the lunar eclipse.
Backward chaining starts with a goal then searches back. Forward chaining starts with facts and searches forward.
Because in asexual reproduction, only one parent is needed; unlike sexual reproduction that takes a male and female mating to produce offspring.
Cloning comes from a single parent that has not mated; the offspring will have the exact same DNA as the parent.
