X-rays carry a small risk of damaging DNA which can lead to cancer. Why are they still used by doctors?
Answer:
Despite the risk of DNA damage and cancer production, X-rays are still used by doctors because the benefit of this diagnostic study outweighs the risk, which in most cases is very low.
Explanation:
Diagnostic radiology studies, such as X-rays and CT scans, are procedures that use ionizing radiation to obtain images of the inside of the body. Prolonged or constant exposure to this type of radiation is harmful because there is a risk of producing damage to DNA and can lead to the development of cancer.
However, the use of X-rays and CT scans are non-invasive diagnostic methods whose information provides an accurate diagnosis of a disease and, when well used, has a very low risk of organ damage.
Ionizing radiation is measured in milisieverts (mSv) and exposure from radiologic studies is in the range of 0.1 to 10 mSv per study. The amount of ionizing radiation a person is expected to receive per year from exposure to their environment is in the order of 3 to 5 mSv per year, so diagnostic imaging studies involve a low risk of organ damage.
Doctors continue to use X-rays as a diagnostic study, despite the risk of cancer and DNA damage, because the benefit —accessible, noninvasive, and cost-effective— far outweighs the risk.

Individuals with advantageous traits for their environment have a better chance of surviving
than those with less helpful traits. Explain how this is demonstrated in the moth information
above. Use specific information and examples.
Answer:
The moths with darker coloring lived long enough to reproduce and passed the trait on. The light peppered moths were easier for predators to spot on the dark soot covered trees so they died first.
Explanation:
What do variations create?
Variations in species help them to adapt themselves to that particular environment and give them a chance of survival. For example, thermophilic bacteria are variants that are resistant to extreme temperature. They have a chance of survival in high temperate zones while others die.
What are some benefits to evolutionary adaptations?
Answer:
1.A new species
2.Adding to world population
3.More to learn

summarize the future use of dna technology here in 20 words or more
Answer:
DNA testing has gone mainstream. The cost of DNA sequencing has reduced faster than Moore's Law. With an estimated cost of $100 in the foreseeable future, DNA sequencing becomes more accessible and opens up new use cases, such as wider adoption of population sequencing
Explanation:
Which of the following provides the best example of artificial selection?
O Scientists have noted that different varieties of birds on different islands have beaks
that are suited to each bird's available food.
O Leopard seals captured in Antarctica have thicker layers of blubber than harbor seals
captured in the Pacific Ocean.
O Hummingbirds have a long, narrow beak that enables them to reach food in the
deepest parts of a flower
O Racehorses that run fastest are the ones that are allowed to produce offspring, leading to faster racehorses.
Answer:
O think it's either B or D
List the cell organelles involved in energy generation for the cell.
Answer:
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.

One of Earth's characteristics is that it experiences seasons. Higher
temperatures result in summer and lower temperatures result in winter.
Why does the Earth experience seasons? *
A. Temperatures on Earth vary from one location to another, causing seasons.
B. Cloud cover is heavier in the winter, blocking radiation from the Sun and creating
seasons
C. As Earth revolves around the Sun, the hemisphere that is tilted toward the Sun
receives more direct sunlight, causing seasons
D. Earth's orbit around the Sun is elliptical, and Earth is farther from the Sun in winter,
resulting in seasons
Nas
Answer:
C.
Explanation:
earth's orbit around the sun is an elliptical orbit that requires about 365 1/4 days to complete. When Earth's axis points towards the sun it is summer to that hemisphere

Describe how a carbon atom is released from a fossil fuel like coal and travels into the atmosphere as a gas. How does it then end up in living things like plants and animals? Explain how carbon ends up back in the ground. Use the following terms in your typed response: CO2, C6H12O6, atmosphere, lithosphere, hydrosphere, biosphere, carbon sink, carbon source.
Explanation:
Animals and plants need to get rid of carbon dioxide (c02), this process is called respiration. Respiration happens when the plant/animal breaths in air and releases it as carbon, carbon then moves from fossil fuels to the atmosphere where they are burned. When humans burn fossil fuels to power cities, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
