7 0

Answer:

Lunar Eclipse: The moon moves in an orbit around Earth, and at the same time, Earth orbits the sun. Sometimes Earth moves between the sun and the moon. When this happens, Earth blocks the sunlight that normally is reflected by the moon. (This sunlight is what causes the moon to shine.)

2. Bone
rodikova [14]

Osteoporosis causes bone density to decrease due to decreased osteoblast activity, increased osteoclast activity, and external factors like long-term medication. Option B. All choices are potential causes.

<h3>What are the factors that promote osteoporosis?</h3>

Let us first review what the bone cells are and their functions,

• Osteoprogenitores → in charge of osteocytes production

• Osteocytes → maintain the matrix

• Osteoblasts → Synthesize and secrete osteoid matrix that will later calcify

• Osteoclasts → Phagocytic cells in charge of osseous resorption and bone modulation.

Osteoporosis is a no-symptoms disease -silent- that causes a decrease in the bone mineral and mass density and might change the bone structure.

Osteoporosis weakens the bone until it breaks. So this affection becomes evident when a fracture occurs.

Several factors lead to osteoporosis development. Among them, we can mention,

  • genetic factors,
  • habits factors (lifestyle),
  • hormonal alterations,
  • drugs/medication

The increased rate of bone resorption is the major mechanism by which osteoporosis occurs. It deteriorates bone structure and decreases bone density.

Bone resorption and deterioration might be caused by

  • a decrease in osteoblast activity, leading to the decrease in osteoid matrix formation and calcification,

  • an increase in osteoclast activity, enhancing the activity of these phagocytic cells.

Other external factors also increase the probability of developing osteoporosis. Some of them are,

  • long-term medications (for instance, those used in cancer treatment)
  • excessive alcohol consumption and smoking
  • sedentary lifestyle
  • poor diet

According to this framework, the potential causes of the Osteoporosis are Decreased osteoblast activity, Increased osteoclast activity, Secondary to external factors like drugs/cancers.

Hence, <u>option B is correct</u>, All choices are potential causes.

ACE inhibitors work on the renin-angiotensin system to prevent the conversion of angiotension I to angiotensin II. Because this
stich3 [128]

Answer:

c) unrelenting cough

Explanation:

  • ACE inhibitors stand for Angiotensin-converting-enzyme inhibitors.
  • ACE inhibitors are used for the treatment of high blood pressure and heart diseases.
  • These inhibitors perform their action by causing a relaxation of the blood vessels which results in decreased blood pressure.
  • Further, these inhibitors prevent the conversion of angiotensin I to angiotensin II and the site of this conversion is the lungs, since this conversion is blocked by these inhibitors, an unrelenting persistent cough is a common side effect associated with the use of these inhibitors.

A chemical equation is balanced when each side of the equation includes the same number of each type of atom.
Mariana [72]
<h3><u>Answer: </u></h3>

A. NO, the equation is NOT balanced.

B. C₆H₁₂O₆ + 6 O₂ →  6 H₂O + 6 CO₂

<h3><u>Explanation:</u></h3>
  • The chemical equation of cellular respiration is given by:  

C₆H₁₂O₆ + 6 O₂ →  6 H₂O + 6 CO₂

Where glucose or sugar is broken down in presence of oxygen in presence of oxygen to yield energy in the form of ATP and water and carbon dioxide as a byproduct.

  • The given chemical equation is not balanced as the number of atoms of each element on reactant side are not equal to those on the product side.  
  • Initially,there are 12 Hydrogen atoms, 18 Oxygen atoms and 6 Carbon atoms on each side.  To balance the equation we put a 6 on carbon dioxide and a 6 on water on the product side.
  • The balanced equation will be;

C₆H₁₂O₆ + 6 O₂ →  6 H₂O + 6 CO₂
