How are nails formed

Biology
2 answers:
Damm [24]3 years ago

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 fromed nail then slides along the nail bed, the flat surface under your nails.

Nails themselves are made of keratin (say: KAIR-uh-tin). This is the same substance your body uses to create hair and the top layer of your skin. You had fingernails and toenails before you were even born. Where do they come from?

It may look like your fingernails and toenails start growing where your U-shaped cuticle (say: KYOO-tih-kul) begins. But there's more going on under the surface. 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. The nail bed sits on top of tiny blood vessels that feed it and give your nails their pink color.

Your fingernails grow slowly — in fact, they grow about one tenth of an inch (2.5 millimeters) each month. At that rate it can take about 3 to 6 months to completely replace a nail.

Explain why polar and ionic R groups are hydrophilic.
Elenna [48]

Explanation:

They are hydrophobic. About 5 amino acids have polar side chains, R-groups which do not ionize or become positively or negatively charged. These R-groups are neither strongly hydrophilic nor hydrophobic. Atoms in long molecules, such as polypeptides, are not rigidly fixed in space or position

<h3>What are the benefits of technology?</h3>

Sales will probably improve as a result of technology that makes it simpler for people to buy from you, including an e-commerce solution and numerous payment apps. Marketing departments are forced to adapt the social media platforms that your clients and potential customers use since they are born and die on a monthly basis.

The tasks that HR departments perform for hiring, reviewing applicants, onboarding, and training involve a significant amount of technology. The more HR duties you can complete using technology, the quicker they can be completed and the less likely it is that you will make a mistake that could result in a lost recruit, an employee leaving, or a lawsuit. Employee education on topics like benefit enrollment and corporate policies, for instance, guarantees appropriate paperwork is done and cuts down on training time for new hires.
