Answer:
New Moon
Explanation:
This is when the moon is between the sun and the earth. The side of the moon that faces the earth is in darkness hence cannot be viewed with the aided eye from the earth and the sun and moon rise and set together. During the daytime the glare of the sun makes it harder for us to see the new moon. A slight halo is visible around the moon because some light from the sun which is behind the moon goes around the. When the new moon just crosses the elliptic orbit blocking the sun rays from reaching earth and causing a shadow over the earth, this is when a solar eclipse occurs. You realize that the moon’s orbit is inclined relative to the ecliptic orbit hence solar eclipse does not occur with every new moon.
Answer/Explanation:
EGFR stands for epidermal growth factor receptor. It is a transmembrane protein acting as a tyrosine kinase receptor for epidermal growth factor ligands, which are associated with promoting cell division and proliferation. When epidermal growth factor binds to the receptor, it becomes activated and undergoes dimerization and autophosphorylation.
A mutation could occur making the receptor overactive. That is, it does not require ligand binding to become activated, meaning it is always in an "on" state. This would lead to uncontrolled proliferation, a hallmark of cancer.

What is myocardial infarction?</h3>
- A myocardial infarction (MI), also referred to as a heart attack, happens when blood flow to the heart's coronary artery is reduced or interrupted, harming the heart muscle.
- The most typical symptom is discomfort or soreness in the chest, which may radiate to the shoulder, arm, back, neck, or jaw. It frequently lasts more than a few minutes and usually happens in the center or left side of the chest.
- Sometimes the discomfort may feel like heartburn. Other signs and symptoms could include fatigue, shortness of breath, nausea, feeling dizzy, and cold sweats.
- Atypical symptoms are present in about 30% of patients. Women more frequently experience arm, neck, or fatigue discomfort instead of chest pain.
