Answer:

The laws of thermodynamics are important unifying principles of biology. These principles govern the chemical processes (metabolism) in all biological organisms. The First Law of Thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed. It may change from one form to another, but the energy in a closed system remains constant.

Suppose there is a protein "A" which binds to a DNA sequence and increases transcription of the gene CBC23. In the presence of m
fenix001 [56]

Answer:

A = Activator

B = Effector

Explanation:

An activator is a protein which typically binds to a short (50–1500 bp) region of DNA which might be located either upstream (mainly) or downstream of a gene so as to cause increased transcription. This particular region of DNA is known as enhancer and activator is also  known as transcription factor. Activator is a trans-acting factor which binds to the cis-acting factor which is enhancer so as to enhance transcriptional expression.

But another protein named as effector may restrict activator from binding to the enhancer leading to a decrease in transcriptional expression by binding to the activator allosterically. Allosteric binding of effector to the activator causes conformational change in activator so it can no longer bind the enhancer.

zhenek [66]

Answer:

Cochlear duct.

Explanation:

The mammalian ear is divided into three parts- outer ear, middle ear and inner ear. Ear is an important organ of the body responsible for maintaining the body's equilibrium.

The cochlear duct is well known as scala media. The cochlear duct is present between the perilymphatic chambers. This duct is interconnected at tip of the cochlear spiral.

Thus, the answer is cochlear duct.
