OleMash [197]
There are three main layers of skin. The epidermis, the outermost layer of skin creates a waterproof barrier and creates our skin tone. The dermis contains tough connective tissue, hair follicles and sweat glands. The last layer is the hypodermis which is made of fat and connective tissue

Explain how the ozone layer forms, how human activities have damaged it, and the consequences of the destruction of the ozone la
Vikki [24]

Answer:

Ozone is formed in the stratosphere naturally.

High energy solar radiation strike the oxygen atoms O2, the two atoms split apart. The freed atom collides with another oxygen atom O2 forming O3 (Ozone)

Ozone layer is destroyed when chloroflourocarbons and halons.

CFCs and halons cause chemical reactions that break down ozone molecules. Consequences ofnozone depletion are that UV radiations are not filtered and they reach the earth causing damage to eyes and skin.

Explanation:

Ozone layer is a protective layer which protects from UV damaging radiations. It is formed when oxygen atoms are broken down by photolysis and a freed oxygen atom combines with another amd form O3.

Ozone is being depleted now because chlorofluorocarbons (CFCs) and halons—gases found in aerosol spray cans and refrigerants—are released into the atmosphere they decrease the ozone's ultraviolet radiation-absorbing capacity.Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include skin cancers, eye cataracts and immune deficiency disorders.

Explain how a covalent bond is different than an ionic bond. Which type of bond is the stronger of the two bonds? Give examples
Kobotan [32]
A covalent bond is a bond between 2 non-metals (sharing of electrons between atoms), where ionic is between a metal and a non-metal (the transfer of electrons). Standard covalent bonds are usually weaker then ionic bonds. 

Covalent - Hydrogen + Chlorine = Hydrogen Chloride (HCl)

Ionic - Sodium + Chlorine = Sodium Chloride (NaCl)

The primary function of the chromosome is to?
aleksandrvk [35]

Explanation:

<u>Chromosomes store genetic information. </u>

<u></u>

All the genetic information within the eukaryotic cell is preserved as helical DNA within the nucleus. This DNA is tightly wrapped around histones as chromosomes.

Further Explanation:

DNA sequences contain genes that may have different forms called alleles. The genotype of DNA is transcribed into mRNA and subsequently translated into amino acids that are linked together by rRNA to form proteins that form the phenotype of an organism. Mutations in the DNA sequences affect the corresponding mRNA and therefore the encoded protein

Spontaneous changes that occur within the genome during the cell division process, called mutations. These errors occur as copies of DNA are produced inside the cell; mutations can range from small modifications, called single nucleotide polymorphisms, to large-scale deletions and multi-gene additions.
