larisa [96]

Answer:

The correct answer is option a.

Explanation:

Osteoporosis refers to a condition that weakens the bone, and enhances the threat of unanticipated and sudden fractures, also known as porous bones. It leads to an enhanced loss of bone mass and strength. The disease often advances without any kind of pain or signs.  

There is a direct association between the reduction of estrogen post menopause and the emergence of osteoporosis. Postmenopause, the breakdown or resorption of bone takes over the formation of novel bone. Estrogen diminishes the function and number of osteoclasts. Thus, the reduction in the levels of estrogen after menopause leads to bone loss.

Gemiola [76]

The plasma membrane of the enveloped alga cell serves as the source of the apicoplast's second outermost membrane.

Chloroplasts were first established in eukaryotes through an endosymbiotic relationship with a cyanobacterium; they later spread through the evolution of eukaryotic hosts and the subsequent engulfment of eukaryotic algae by formerly nonphotosynthetic eukaryotes.

<h3>How did eukaryotic cells develop mitochondria and chloroplasts?</h3>

Chloroplasts and mitochondria most likely developed from engulfed bacteria that once existed as autonomous organisms. An aerobic bacterium was eventually swallowed by a eukaryotic cell, which later established an endosymbiotic bond with the host eukaryote and gradually transformed into a mitochondrion.
