Answer:
<u>Inducer</u>
<u></u>
Explanation:
Structural proteins within bacteria are encoded along with their functions. These are typically found in a block of genes called an operon. They undergo transcription together with the use of a single promoter sequence to form a polycystronic transcript- this allows for the simultaneous control and regulation of biochemical pathways. This is efficient as these pathways would either need to function together when "switched on" or will not be needed when "switched off". Repressors are proteins that effectively hinder translation by binding to DNA at the operator site, blocking the activity of RNA polymerase in transcription. However inducers are small molecules that can displace these, freeing up the operon for transcription and the activation of relevant biochemical pathways.
The mal operon includes genes which mediate the breakdown of the substrate maltose in bacterial cells. Maltose, called a malt sugar, is a carbohydrate compound made up of two glucose molecules joined by an α-(1,4) glycosidic linkage.
In the presence of maltose, the inducer binds to the activator. This then allows for the binding of RNA polymerase, which facilitates translation and th epr
The correct answer is B

This is because the ocean conveyor belt help balance the climate of western Europe,by releasing heat as it moves pole ward, which moderates the cold temperatures in the region.

ANSWER: MITRAL VALVE STENOSIS
EXPLANATION:
The child have the risk of having MITRAL VALVE STENOSIS. It is also referred to as mitral stenosis.
Mitral valve stenosis occurs as results of the mitral valve opening narrowing. Which effect to less blood flowing through it.
The mitral valve is located between two chambers (the atrium and the ventricle) on the left side of your heart.
However, Mitral valve stenosis can lead to different health issues, including blood clots, difficulty breathing, fatigue, and heart failure.
Mitral valve stenosis is specifically caused by rheumatic fever (a childhood disease). This rheumatic fever occurs has a result of the body's immune response to an infection associated with the streptococcal bacteria.
Acute rheumatic fever affects the joints and the heart greatly. It causes joints inflammation temporarily and in severe case causes chronic disability.
Nevertheless, this cardiac complication have treatment and it is based on whether the affected individuals shows symptoms. Medications like blood thinners or anticoagulants (to reduce the risk of blood clots), diuretics, antiarrhythmics (to cure abnormal heart rhythms), beta-blockers (to slow your heart) etc, are being administered based on the level of the complication.
