Answer:
The larva gets dark pigment.
Explanation:
If scientists purposely injected an excess concentration of these proteins in the larva, the larva gets deep dark colour because this protein is responsible for the pigment colour in the larva of Drosophila. By increasing the protein concentration the pigment will also have a very dark colour. So we can conclude from this that increasing the amount of protein causes increase in the pigment colour.
Animal cells do not have chloroplasts because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
and plant cell need chloroplast because plants don't get their sugar from eating food, so they need to make sugar from sunlight so they have chloroplast
Answer:
enzymes have an activation site that fits a substrate. when the substrate is attached to the enzyme, the enzyme acts as a catalyst and breaks the substrate apart or binds it together. ... denaturing occurs when the control changes the enzymes shape.
Answer:
Release factors will be bound to the A site of the ribosomes when the stop codon appear
Explanation:
The stop codon are not recognizable by tRNA so Release factor 1 will recognize UAA and UAG stop codons or Release factor 2 will recognize UAA and UGA stop codon, gets bind to the A site of ribosomes and triggers the hydrolysis of ester bond in peptidyl tRNA (between peptide and tRNA) and facilitates the release of newly synthesized peptide chain from the ribosomal assembly. Later on Release Factor 3 will catalyzes the removal of Release factor either 1 or 2 depending on the type of codon present on mRNA from the ribosomal assembly.
b) introducing biological predators eg to kill mice in rice field snake can be used
