The given image is showing the interaction of the enzyme and its substrate.
In the first part of the image, the enzyme and substrate are not bind together. They are present in close proximity. The enzyme shown in the picture have a site for the attachment of the substrates.
In the next picture, the interaction of the enzyme and the substrate has occurred, which resulted in the formation of the enzyme substrate complex. Hence, the given picture shows the interaction of an enzyme with the substrates.
Listed under are the 5 different type of cells found in the epidermis and their description:
1. Stem cells
These are what you call undifferentiated cells. These are cells found in the stratum basale, which is the deapest layer of the epidermis. These cells divide to create keratinocytes.
2. Keratinocytes
The make up the majority of the cells in the epidermis. They synthesize keratin which are proteins that make up your hair, skin, and nails. They can also be found in other organs inside your body.
3. Melanocytes
These cells can only be found in the stratum basale. They synthesize melanin with a brown to black pigment. These dark pigments serves as protection for the skin from harmful UV rays.
4.Merkel cells
Merkel cells are also known as <em>tactile cells</em>. They are the sensory receptor for touch. Merkel cells and the nerve fiber together are called the Merkel disc.
5. Dentritic cells
They are also known as <em>Langerhans cells</em>. They can be found in two layers of the epidermis: the stratum spinosm; and stratum granulosm. They are what you call macrophages that come from the bone marrow. They serve as immune cells that provide protection against toxins, microbes and other pathogens that try to penetrate the skin.
Hope you find some information above that will help you.
<span>The horizontal line present across the front teeth are called perikymata. These are incremental growth lines that appear on the surface of tooth enamel as a series of linear grooves. These lines can be used to assess how long the crown of the teeth formed. </span>
Answer:
If we're talking about human organism then
It is multicelular.
It has a backbone.
It contains cells without nuclei.
Explanation:
human as almost all animals in the world is multicellular meaning they have more than one cell (some bacterias has only one)
backbone or "vertebra" is the is the bone of our back who supports us making us stand up.
Yes our cells contain nuclei
, The nucleus contains nucleoplasm, a component where it is immersed in genetic material and as structures that are important for the performance of its functions
And finally our body don't have radial symmetry, radial symmetry is when you can "cut" the image in more than one piece keeping the symmetry in every side, some animals with radial symmetry are the starfish and the jellyfish.
