Believe it or not, dandelions don't grow on stems but rather, they grow on the crown of the plant at ground level. The flowers also grow on empty stalks that are able to react up to 70cm.

Unlike plants that send spores or gametes to fertilize or create a seed, dandelions actually use petals with a seed attached to send them away farther distances. They don't rely on insects such as bees though the bees may be reliant on the other hand. Dandelions may use the process apomixis which is when seeds develop without germination.
To start off, if some of you think you have a skin without hair, guess again.
By looking under a portable microscope, you will likely notice bits of hair shooting out like in these pictures.
As you see in these pictures, the keratin layer is a significant part to our body, having not only dead skin cells laid at the epidermis, but also presenting an optical view of ourselves. Here in the picture, skin is with wrinkles though not quite visible with just the naked eye,
Believe it or not, but even people in youth have wrinkles like these! The wrinkles only intensify as you age because less collagen are produced and elastic fibers become less elastic leading to sagging and wrinkling. Following, the dullness shown on skins as one ages is because less moisture is transported to the epidermis as well.
When I first saw this, I didn't believe it was supposed to be how a semi-cylindrical piece of wood looked like up close.

Corks are generally made of an impenetrable buoyant material. The dark gray bark that covers a corn oak is used to create the cork. While peeling off the tree bark may seem harmful, corn oaks are unique because of their ability to regenerate their outer layer.

I personally didn't expect the cork to look as rough because it seemed quite smooth when viewed through the naked eye. But since it was made from the bark of an oak tree, I could also understand why the cork was quite bumpy.
Some time ago, I posted pictures of a single tear drop and an artificial one as well in order to compare their components and structures. One interesting fact is the components in a tear drop differs depending on the situation one is in. For example, if one is emotional, tear drops may have different components as compared to when a tear is dropped from staring at an onion (as seen above).
A post I did sometime back regarding the BO blood type was actually from this blood. However, what I didn't mention there was what the pathogen fighters in the blood streams were: white blood cells (Leukocytes or Leucocytes).
As seen in the video and the chart, there are actually a variety of white blood cells! For example, the white blood cell in the video with multiple spots surrounding it is seen as a basophil! Each white blood cell has different functions and appearances.
Five of the most important white blood cells and their functions are:
1. Neutrophils: They are the most abundant and they use phagocytosis to destroy pathogens (engulfing of the pathogens).
2. Lymphocytes: Second most abundant and has B cells, which create antibodies that destroy pathogens targeting immune system cells, and T cells which aid in recognition of attacking germs.
3. Monocytes: Largest type of white blood cell and has receptors that detect chemical signals that indicate whether or not there is an infection or inflammation.
4. Eosinophils: 1-4% circulate in the bloodstream and are significant for fighting parasitic infections such as those that may cause malaria.
5. Basophils: Least common white blood cells that have surface receptors capable of binding a type of antibody responsible for allergic reactions,
