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.
In order for cells to become whole organisms, they must divide and differentiate. Cells divide all the time. That means that just one cell, a fertilized egg, is able to become the trillions of cells that make up your body, just by dividing. Those trillions of cells are not all the same though.
Just a little while after you started out as a fertilized egg, your cells started performing specific tasks, even started to look different because of that. Differentiation means that one cell performs a different function than another cell, depending on where it is in your body.

During your internship at Big Pharma, you discover a compound that opsonized the herpes simplex virus, reducing the duration of the outbreak. Which step of viral replication is the drug most likely interfering with
A. Attachment
B. Penetration
C. biosynthesis
D. Viral assembly/ maturation
E. Viral release is interfered
Answer: E. Viral release is interfered
Explanation:
Herpes virus is responsible for causing sores in the mouth and around it. The sores can also be found on the genitals. This virus is transmitted by sexual intercourse. The opsonization can help in reducing the time duration for the outbreak to occur.
The immunoglobulins will attack the virus particles and will have a phagocytic action on them by engulfing them. Thus this provides a barrier to the release of new viral particles in the host genome and provides immunity to the body.
Answer: population, more
Explanation:
Carrying capacity is the size of the population of species that an ecosystem can support in terms of providing essential resources for survival. When the population of the species exceeds the carrying capacity then the population experience decline in population.
An population which produces more number of offspring than the environment can actually support then this will lead to the decline in the population due to the increase in the population beyond the carrying capacity.
C. The combination of high winds and flood waters.
