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.

Which three of the following entities are acellular?.

arsen [322]

Answer:

Prions archea, viroids bacteria, viruses protists are acellular while fungi is cellular.

While viruses have indeed been closely researched for more than a century for infections of people and animals, most viruses, particularly those that infect microorganisms, are still poorly understood.

Pathogenic RNA molecules are known as viroids. Contagious protein particles are identified as prions. Viruses are larger than that of viroids. Viroids are larger than prions in size.

Molds, wild yeasts, as well as mushrooms are examples of fungi. Numerous fungi are multicellular and also have nuclei in their cells. A protein-encased DNA or RNA core defines viruses being non - cellular organisms. Some scientists disagree with the notion that viruses are living things.

What is the relationship among chromosomes, Gene's and dna

GarryVolchara [31]

DNA, which is a sequence of nucleotides, make up genes. Genes are DNA sequences that code of a functional protein and are controlled by a promoter region on the DNA. DNA, including genes within it, are supercoiled into chromosomes so they are able to fit in the cell. Otherwise, uncoiled DNA in a cell is much longer than the cell itself.

Take a look at the layers of earth and the fossils in each layer. The fossils show us that life forms changed in an area. Compar

1. What did Linnaeus use to classify living things?

tino4ka555 [31]

Answer:

Perhaps the single greatest contribution Linnaeus made to science was his method of naming species. This method, called binomial nomenclature, gives each species a unique, two-word Latin name consisting of the genus name and the species name. An example is Homo sapiens, the two-word Latin name for humans.
