Studies have shown that children are especially vulnerable to the effects of ultraviolet (UV) radiation. Tanning beds expose the skin to nearly ten times as much UV radiation as natural sunlight. With that knowledge, a law was passed in some states to prevent individuals under the age of 18 from using tanning beds. Which statement best explains why UV radiation is so harmful?
a) It can increase harmful DNA mutations in cells.

b) Diseases are all caused by exposure to environmental factors.

c) Homeostasis in an organism is increased by the presence of UV radiation.

d)UV Radiation decreases the likelihood that mutations will occur.

Answers

Answer 1

Hello there!!

The answer, I think, would be A.

UV radiation can create problems in the correctness of cell replication, which can result in mutated cells.

I hope this answers your question!

Answer 2

Tanning beds can increase harmful DNA mutations in cells. So, the correct option is A.

What are Tanning beds?

In order to tan individuals, a tanning bed emits UV radiation (make their skin darker). If someone spends too much time in the tanning bed, it can also burn their skin, much like the sun. Many types of tanning beds exist. Using tanning beds can lead to more damaging DNA alterations in cells.

Special fluorescent lights (16–32 per tanning bed) that produce both visible and UV light are used in tanning beds. They employ a ballast system, like all fluorescent lights, to keep the amount of electricity going to each lamp to a maximum of 100 watts per lamp. A specific acrylic, or clear shield, is used over the bulbs in tanning beds.

Therefore, the correct option is A.

How are fossil fuels related to climate change?
A. Fossil fuels absorb carbon dioxide, a greenhouse gas, as they
burn.
B. Fossil fuels release carbon dioxide, a greenhouse gas, as they
burn
C. Fossil fuels release a great deal of heat as they burn.
D. Fossil fuels are greenhouse gases.

Answers

Answer:

B. Fossil fuels release carbon dioxide, a greenhouse gas, as they

burn

On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

B. Fossil fuels release carbon dioxide, a greenhouse gas, as they burn.

What are fossil fuels?

Fossil fuels are non-renewable resources that are formed over millions of years from the remains of dead plants and animals. They include coal, oil, and natural gas, which are used to generate energy and power many modern-day technologies.

Fossil fuels are found in deposits beneath the Earth's surface, and they are extracted through mining or drilling. They are burned to release energy in the form of heat or electricity, making them a primary source of energy for transportation, electricity generation, heating, and cooling. However, the burning of fossil fuels also releases greenhouse gases, which contribute to climate change and other environmental problems.

When fossil fuels such as coal, oil, and natural gas are burned, they release carbon dioxide (CO2) and other greenhouse gases into the atmosphere.

These greenhouse gases trap heat from the sun, causing a warming effect on the Earth's surface. This phenomenon is known as the greenhouse effect, and it is a significant contributor to climate change.

As the concentration of greenhouse gases in the atmosphere continues to increase, the Earth's temperature rises, leading to changes in climate patterns, rising sea levels, and more frequent extreme weather events.

what system carries auxin to move to the darker side?

Answers

Vascular system.

Phototropisms are caused by an unequal distribution of auxin. This makes the plant grow either towards or away from the light, depending on which part of the plant receives the light.

In a stem, the cells on the shaded side contain more auxin and grow longer than the cells on the light side. This causes the stem to grow towards the light. It is vital to note that the plant does NOT bend towards the light.

Phototropisms are a result of an unequal distribution of auxin. This makes the plant develop both in the direction of or far from the mild, relying on which part of the plant gets the mild.

In a stem, the cells at the shaded aspect comprise greater auxin and develop longer than the cells at the mild aspect. This reasons the stem to develop in the direction of the mild. It is crucial to be aware that the plant does NOT bend in the direction of the mild.

What are auxins?

Auxins are a category of plant hormones (or plant-boom regulators) with a few morphogen-like characteristics. Auxins play a cardinal position in the coordination of many boom and behavioral procedures in plants cycles and are important for plant frame development.

Thus it is clear that the system that carries auxin to move to the darker side is the vascular system.

Arrange these components of the mammalian immune system as it first responds to a pathogen in the correct sequence. I. Pathogen is destroyed and digested and parts are presented. II. Lymphocytes secrete antibodies. III. Antigens from pathogens bind to matching receptors on lymphocytes. IV. Lymphocytes specific to a pathogen's antigens become numerous. V. Only memory cells remain.

Answers

Answer:

The correct sequence is:III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes.

IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.

II) Lymphocytes secrete antibodies.

I) Pathogen is destroyed.

V) Only memory cells remain.

Explanation:

Effective resistance against infection is essential for the development and functioning of the mammalian organism, and for it to be effective, multiple defense systems must be available. In order to meet these objectives, the body has developed a complex system of overlapping and interrelated defense mechanisms, which together can destroy or control almost all invaders.III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes. It consists of the binding of the foreign antigen to the specific receptors existing on the membrane of mature lymphocytes. The B lymphocytes that mediate humoral immunity express antibody molecules on their surface, which bind to foreign proteins, polysaccharides or lipids in their soluble form; T lymphocytes, responsible for cellular immunity, express so-called T cell receptors (TCR), which recognize small sequences of antigenic peptides.

IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.II) Lymphocytes secrete antibodies.

Activation phase: sequence of events that occur in lymphocytes as a result of specific antigen recognition. All lymphocytes undergo two fundamental changes: a) proliferation: expansion of antigen-specific clones and amplification of the protective response, in which the CD4 T lymphocyte, capable of activating CD8 B and T lymphocytes, assumes a preponderant role; b) differentiation: stage in which effector cells and memory cells are formed. The first produce various substances that can interact with the antigen, such as antibodies and lymphokines; the second are partially differentiated lymphocytes, that is, they do not become effector cells.

I) Pathogen is destroyed.

In this phase, the T lymphocytes differentiated into effector cells migrate to the sites of attack, where they carry out their functions of eliminating pathogens, while the B lymphocytes perform them in the peripheral organs themselves.

V) Only memory cells remain.

One of the most important consequences of the adaptive immune response is the establishment of the state of immunological memory, which lies in the ability of the immune system to respond more quickly and efficiently to microorganisms that have previously infected the host and it reflects the preexistence of a clonally expanded population of antigen-specific lymphocytes. We call, therefore, the immune response that the organism gives when it comes into contact for the first time with a foreign agent and from which a series of events derives that include nonspecific innate defense mechanisms and adaptive response mechanisms, if the pathogen manages to survive the first ones.
