Answer:
Explanation:
Left coronary artery - divides into two branches (the circumflex artery and the left anterior descending artery). Left anterior descending artery (LAD) - supplies blood to the front and bottom of the left ventricle and the front of the septum. Pulmonary veins - bring oxygen-rich blood back to the heart from the lungs.
Answer:
E. First premolar and second premolar
Explanation:
First premolar and second premolars because In the cusp-embrasure occlusal relationship, the maxillary first premolar is most likely to articulate with the first and second premolars.
The correct answer is D) An apparently longer survival time among persons identified during a screening program because they were identified at an earlier stage of their disease
Explanation:
In medicine, screening is a method to diagnose diseases even if the person has no symptoms; due to this, screening is related to earlier detection of diseases than traditional diagnosis based on symptoms. Early diagnosis does not imply longer survival time, but it can lead to doctors or individuals to perceive the survival time was longer, this phenomenon is known as lead-time bias.
For example, a person diagnosed with cancer at an early stage when he is 45 years old, dies at 50 years old, this means his survival time was 5 years. If the same person is diagnosed at 48 years based on symptoms and he dies at 50 it seems the survival time is less (2 years); however, this is biased as the diagnosis did not change the effect of the disease. According to this, lead-time bias can be described as "an apparently longer survival time among persons identified during a screening program because they were identified at an earlier stage of their disease".
Options:A) activated B) inhibited C) unaffected.
Answer: B. Inhibited.
Explanation:Glycogen phosphorylase is an essential and necessary Enzyme in the Glycolytic partway,it is the Glycogen phosphorylase that acts on the reaction at the initiation of glycogen degradation.
Glycogen phosphorylase have different roles in the Glycolytic partway as in some cases it is activated in another it is inhibited, Glycogen phosphorylase is being studied as a model protein that is controlled by both reversible phosphorylation and allosteric effects(The binding of a ligand to one site on a protein molecule so that the characteristics of another site on the same protein are affected)
Glycogen phosphorylase is inhibited.in response to insulin signal in the muscles.
