<span>A big variety of organisms’ genomes have genes that control the organisms’ development at different stages. The remains of ancestral traits usually appear at different stages of the embryological development. For example, hair growth and loss, the development and deformation of the yolk sac or appearance and disappearance of gill structures in the embryo development of vertebrates.</span>

Similar patterns of embryological development provide further evidence that organisms have descended from a common ancestor.  All species share a common descent, a group of organisms share common descent if they have a common ancestor. There is strong quantitative support for the theory that all living organisms on Earth are descended from a common ancestor.

The most distinctive characteristic of leaf mesophyll cells is that they are filled with
Katyanochek1 [597]
<h2>Mesophyll cells</h2>

Explanation:

The most distinctive characteristic of leaf mesophyll cells is that they are filled with many chloroplasts

Mesophyll cells constitute the main body of a leaf, occurring between upper and lower epidermis

Typically, the leaves of temperate-zone plants have two layers of mesophyll cells, the palisade mesophyll on the upper side and the spongy mesophyll on the lower side

The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves

The spongy mesophyll is composed of large, often odd-shaped, photosynthetic cells separated from one another by large, intercellular spaces, these intercellular spaces apparently facilitate the exchange of photosynthetic gases

Age why does the skeletal system become more brittle and susceptible to breakage?
dusya [7]

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.
