Alex_Xolod [135]

During a myocardial infarction, proteins that are normally inside the cells leak into the plasma, due to loss of plasma membrane integrity.

<h3>Cardiac disorders and it's effects:</h3>

There are different types of cardiac or heart disorders that occurs due to different etiological origins.

Example of a cardiac disorder is the myocardial infarction.

Myocardial infarction is defined as the blockage of blood flow to the heart by the presence of blood clot.

This hinders the delivery of oxygen carried by the blood to tissue cells leading to apoptosis (which is a programmed cell death).

This will cause the plasma membrane of cells to lose its integrity leading to leaking of proteins into the plasma.

slava [35]

Answer:

Repressor protein

Explanation:

Repressor is a protein that binds to deoxyribonucleic acid(DNA) or ribonucleic acid(RNA) it inhibits the expression of one or more genes which is done by binding to the associated silencers.

A DNA binding repressor works by blocking the attachment of RNA polymerase an enzyme that enhance transcription to the promoter, thus preventing genes from been transcribed into messenger RNA.

An RNA binding repressor binds to the messenger RNA and prevents translation of the bases on the messenger RNA into protein. The blocking of expression is called repression.

Suppose that the mice with unlimited access to water produced more urine than the mice given no access to water. how would that
kupik [55]

<span>The ratio of both groups would stay the same. Reason being the ratio in urine osmolality is divided by blood osmolality. The mice with no access to water the ratio of urine osmolality to blood osmolality are 14:7 while for mice with unlimited access to water the ratio of urine osmolality to blood osmolality is 1:4. In conclusion, the mice with no access to water produce highly concentrated urine.</span>
