Yolks are an important component of the eggs since they nourish the young embryo as it develops into a young juvenile organism. The yolk is important especially when the embryo is not attached to its parent (in oviparous organisms) like in humans. Humans embryos are able to get their nourishment directly from their mothers in the womb (through the placenta) hence don’t require a yolk (viviparous organisms).

Accurate about snowflakes
valentinak56 [21]

Answer:

snowflake is a single ice crystal that has achieved a sufficient size, and may have amalgamated with others, then falls through the Earth's atmosphere as snow.Each flake nucleates around a dust particle in supersaturated air masses by attracting supercooled cloud water droplets, which freeze and accrete in crystal form. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another, but may be categorized in eight broad classifications and at least 80 individual variants.

The main constituent shapes for ice crystals, from which combinations may occur, are needle, column, plate, and rime. Snow appears white in color despite being made of clear ice. This is due to diffuse reflection of the whole spectrum of light by the small crystal facets of the snowflakes

marusya05 [52]

Answer:

the approach has been described below

Explanation:

I will have to use motivation as a way of enhancing change in the life of Sally. From this question, she seems to be a lonely lady, with low self-esteem and no physical activity. The first thing I would do is to help to get her out of monotony by motivating her.

Once motivated, I would help plan her diet and add combinations of physical activities. These activities may include walking and running. With time an expert would take over her physical training.

She has to make time for other activities such as yoga or community work. The purpose for this is so she can meet and connect with other people, this would give her a sense of belonging. And would help boost her self image.

In conclusion, Sally needs a combination of physical and emotional therapy in order to change her lifestyle.
