Answer:

The correct answer would be - AUGCUUAUC

Explanation:

The new mRNA strands are made by the process called transcription that involves an enzyme that helps to copy a segment of DNA or gene to produce a new RNA strand that encodes for the protein. In this process, a new RNA strand copied the complementary to the sequence of DNA strand. It means adenosine is copied into its complementary form uracil in RNA, Thymin to adenosine, cytosine to guanine and guanine to cytosine.

Original strands: TACGAATAG

new RNA strand: AUGCUUAUC

Temka [501]

The correct answer is Deletion.

DiGeorge syndrome, more commonly considered as 22q11.2 deletion syndrome. It refers to an ailment resulting when a small segment of chromosome 22 is missing. This deletion leads to poor development of many systems of the body.

The medical issues generally associated with 22q11.2 deletion syndrome involve poor immune system function, heart defects, a cleft palate, delayed development with emotional and behavioral issues, and issues associated with diminished levels of calcium in the blood.

A muscle cell undergoes glycolysis to generate pyruvate. Considering that the cell remains under aerobic conditions and moves on

siniylev [52]

The answer is c. oxygen.

Cellular respiration includes glycolysis, link reaction, Krebs cycle, and electron transport chain (ETC), in that order. The main function of ETC is a production of ATP. In this series of oxidation-reduction reactions, electrons from the previous stages of cellular respiration are taken and transported to the oxygen which is the final acceptor of electrons. As the result, water and ATP are produced.

If intrapulmonary pressure was 760 mm hg, what would you expect the intrapleural pressure to be?

Natasha_Volkova [10]

<h3>Answer;</h3>

756 mm Hg

<h3>Explanation;</h3>

Intrapleural pressure is the pressure of the air within the pleural cavity, between the visceral and parietal pleurae. This pressure changes during different phases of breathing.

Due to certain characteristics of the lungs, the intrapleural pressure is always lower than, or negative to, the intra-alveolar pressure. It remains approximately –4 mm Hg throughout the breathing cycle.

Therefore; if the intrapulmonary pressure was 760 mm hg then the intrapleural pressure will be (760 -4) mm Hg, that is 756 mm Hg
