Answer:
Positive (inducible)
Explanation:
Increased levels of CSP induce the receptor to stimulate transcriptional activator functions, which allow gene expression to occur similar to what happens in positive inducible.

It is a fern and belongs to Phylum Pterophyta
Fern is a plant with fronds that are attached to rhizomes. The frond is the leaf of the fern and the rhizome is the root which grows. They have vascular tissue which means that they use tubular structures to transport nutrients throughout the plant. They reproduce by spores and have neither seeds nor flowers.

Loss of Rb, an important part of the G1-S transition checkpoint, can result in uncontrolled cell cycle progression and cancer. All of the following would mimic loss of Rb except constitutively active Ras GTPase activating protein. Correct answer: letter E.
Constitutively active Ras GTPase activating protein would not mimic loss of Rb, because it would not directly result in uncontrolled cell cycle progression.
<h3>What is Retinoblastoma (RB)?</h3>
Rb is an important tumor suppressor protein that works to inhibit cell cycle progression by preventing the activation of E2F transcription factors. Constitutively active Ras GTPase activating protein would not directly interfere with the Rb-E2F pathway, which is necessary for uncontrolled cell cycle progression and cancer.

Answer:
Water sample showing pink/purple color is an error.
Explanation:
Biuret is a blue color reagent that changes its color to pink/purple whenever it detects protein in a sample. Water don't contain proteins so it should not show pink/purple color instead it should maintain the blue color. Food items generally contain proteins so it show pink/purple color but it showed blue color.
Error might have caused by wrong marking of the samples, test tube marked with Water might contain a mystery food while Mystery food tube might contain water.
