Answer:
<h2>True</h2>
Explanation:
1 .Reverse transcriptase (RT) is an RNA-dependent DNA polymerase enzyme which makes DNA from RNA..
2. RT makes double-stranded DNA molecules from ssRNA ( single stranded RNA) molecule using it as a template.
3. Retroviruses like HIV contain Reverse transcpritase (RT) enzyme, which uses the RNA molecule as template and make DNA from it and after that, virus make multiple copies of itself.
4. Reverse transcriptase enzyme make DNA reverse transcrptionally from RNA the process known as RNA dependent DNA polymerase.
5. It was first discovered in retroviruses.
After age 50, bone breakdown (resorption) outpaces bone formation and bone loss often accelerates, particularly at the time of menopause.
What is Osteoporosis ?
Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture. Osteoporosis-related fractures most commonly occur in the hip, wrist or spine. Bone is living tissue that is constantly being broken down and replaced.
Osteoporosis is a disorder where your bones become brittle, fragile, and easily breakable as you age because certain minerals begin to leach out of them. Because estrogen, which helps keep bones strong, is lost during menopause, women over 50 are particularly at risk for osteoporosis.
