Answer:
Rat anti-goat linked to Cy3
Explanation:
Indirect immunofluorescence microscopy is a technique used to localize endogenous marker proteins, having this approach high sensitivity. Secondary antibodies are produced by immunization of the target species with antibodies of one 'second' species. In a standard immunofluorescence assay, the secondary antibodies are linked to fluorophores and incubated with the primary antibody. In this case, the Cy3 fluorescent probe is used for labeling secondary antibodies, it is a fluorophore that absorbs light at 550 nm and emits at 570 nm.
Answer:
preparedness.
Preparedness is the tendency to learn some associations more easily, quickly and permanently than others.
Answer:
Option A, Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.
Explanation:
Negative feedback loop controls the hormone production and release. This is done by eliciting the release of substances till a certain level after which the stop signal is activated thereby preventing further release. By this method, concentration of hormones in blood is maintained within the narrow range.
For example – Thyroid hormones is released when the anterior pituitary signals the thyroid. This continues till the hormones in the blood reach the threshold level. Once the threshold level is reached, hypothalamus receives a feedback and then signals anterior pituitary to inhibit further signaling to the thyroid
Hence, option A is correct
