Answer:
Lunar eclipse
Explanation:
During a lunar eclipse, the earth enters between the sun and the moon, thus preventing sunlight from reaching the moon. There are two types of lunar eclipses: A total lunar eclipse occurs when the moon and the sun are on opposite sides of the earth. When only part of the earth's shadow covers the moon, a partial lunar eclipse will occur. In some cases, it is called a blood moon, similar to the blood moon that occurs this month.
Answer:
osteoblasts.
Explanation:
PTH is produced to prevent hypocalcemia, ie low blood calcium concentrations, which can lead to seizures and heart failure in more severe cases and when untreated. In bone, PTH stimulates and determines the activation and recruitment of osteoclasts (cells that participate in the process of absorption and remodeling of the bone matrix), which results in bone resorption. However, mature osteoclasts do not have PTH receptors, unlike their bone marrow progenitors, known as monoblasts, which undergo the action of PTH leading to stimulation and differentiation in mature osteoclasts.
