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.

The statements Molecule B can be used to produce molecule A and Molecules B and C interact so that amino acids can be joined together are TRUE regarding the structures shown in the diagram (Options B and E).

<h3>What are transcription and translation?</h3>

Transcription is the process by which a DNA template (molecule B) can be used to synthesize a complementary RNA (molecule A), while translation is a process in which an sequence is used as templates to generate a protein, which requires tRNAs (molecule C) to trasnport amino acids to the ribosomes.

Therefore, with this data, we can see that DNA is molecule B used to create RNA, which is molecule A, while tRNA is represented by molecule C and it is used during translation.

In dense forests, obtaining sunlight for plants can be tricky. Growing on the ground is not always effective for plants because
Alex_Xolod [135]

Explanation:

The symbiotic relationship between orchids and trees is called commensalism, which means the orchid and tree host depend on eachother to survive.. The orchid provides the tree with sunlight, (nutrients created by sun- exposure).

the tree provides a solid base for the orchid to climb up the tree, they are dependent on eachother for survival...

A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot
Mama L [17]

Answer:

A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot as a result of "conduction."

Explanation:

The process of the conduction happens because of the flow of kinetic energy from one molecule to the other by direct contact.  When she first steps the beach on the hot sand, after that the energy moves from the hot sand to the cooler body by conduction. While walking on the sand for few time, the feet will feel hot. The movement of the heat takes place from the hot sand to the bottom of the feet by conduction. When the objects come in contact with each other the heat transfers as a result of conduction.
