Answer:
Conditioned response.
Explanation:
Lynn was conditioned to kick her legs as a response to whatever happens after her mom grabs the monkey.
Answer:
A molecule of mRNA is formed.
Explanation:
Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.
The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.
The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.
Note: A molecule of mRNA is formed during transcription
Answer:
Proteins and lipids exist as separate but loosely attached molecules that can move around
Explanation:
Cell membranes are mainly composed of lipids, proteins, and also carbohydrates. Phospholipids are the most abundant type of lipid and the main constituent of the cell membranes. Membrane proteins are divided into two types according to their interactions with the cell membrane: 1-integral (intrinsic) and peripheral (extrinsic) proteins. These peripheral proteins are loosely attached by ionic bonds or calcium bridges with the phosphate heads of the phospholipids; whereas integral membrane proteins contain side chains that interact with fatty acyl groups of the phospholipids. Cell membrane fluidity indicates how easily lipids (e.g., phospholipids and cholesterol) and proteins (e.g., intrinsic proteins) diffuse laterally in the cell membrane. This fluidity is affected by the amount of cholesterol, temperature, and the ratio of unsaturated to saturated fatty acids. Saturated fatty acids have no double bonds in the hydrocarbon chain, whereas unsaturated fatty acids have at least one double bond (these double bonds increase fluidity). Moreover, higher temperatures increase membrane fluidity, whereas cholesterol molecules function to regulate membrane fluidity: at high temperatures cholesterol molecules stabilize the membrane, whereas at low temperatures intercalate between phospholipids, thereby preventing them from clustering together.
