Each cell becomes a thin plate; these plates pile into layers to form the nail. As with hair, nails form by keratinization. When the nail cells accumulate, the nail pushes forward. The skin below the nail is the matrix.
Hair is made of a tough protein called keratin. A hair follicle anchors each hair into the skin. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life
Nails start in the nail root, hidden under the cuticle. When cells at the root of the nail grow, the new nail cells push out the old nail cells. These old cells flatten and harden, thanks to keratin, a protein made by these cells. The newly formed nail then slides along the nail bed, the flat surface under your nails.
Explanation:
It's considered a natural resource because it is energy that is not man made.
It's a renewable energy because it naturally gets replaced.
Answer:
The correct answer is<u> DNA has coded instructions for making proteins, and RNA translates the code.</u>
Explanation:
We can understand this answer with the help of concept of central dogma. Central dogma is the flow of information from DNA to mRNA (transcription) and then decoding the information present in mRNA in the formation of polypeptide chain or protein (translation). Functionally, DNA maintains the protein-encoding information, whereas RNA uses the information to enable the cell to synthesize the particular protein.
The two types of global food webs are the terrestrial and aquatic food webs.
Terrestrial food webs are located or start on land while aquatic food webs are located or start on waters. In this case, these are two connected when one consumer from the other realm becomes part of the food web of the other.
