B. contact with an infected person
C. contact with contaminated food
D contact with a contaminated water
Answer:
The answers is B
Explanation:
I just took a test that had this question on it.
B. contact with an infected person
Transmission occurs when an infected person interacts or exchanges bodily fluids with another person. This can happen before the infected individual even realizes they are sick.
After a weekend field trip to the aquarium with their classmates, five pupils catch a cold. Because they may have come into contact with an infectious person, students became ill. Students became sick as a result of B. contact with an infected person

What happens as electrons move along the chain of molecules known as the electron transport chain?
Answer:
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.
3. Which is an example of genetic biodiversity?

d. All populations look identical within a species
Answer:
A
Explanation:
Has to be the same family to be genetic and you have to find which has the most variety
Different skin color within a species is an example of genetic biodiversity. Therefore, option (A) is correct.
What is genetic biodiversity?
Genetic biodiversity refers to the variety of genes and genetic traits that exist within a population or species. It is a fundamental aspect of biodiversity, as it underpins the ability of species to adapt to changing environmental conditions and to maintain resilience in the face of threats such as disease, climate change, and habitat loss.
Genetic biodiversity arises from mutations, genetic recombination, and other processes that generate new genetic variation within populations. This diversity provides the raw material for natural selection to act upon, allowing organisms with advantageous traits to survive and reproduce.
Genetic biodiversity is important for ecosystem functioning and for the conservation of species, as it helps to ensure that populations are able to adapt to changing conditions and maintain their long-term viability. The loss of genetic biodiversity can have significant negative impacts on populations and ecosystems, making it an important focus of conservation efforts.

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.

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

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.

Which of the following are ways that the respiratory system works with the immune
system to keep humans from getting sick? (Choose all that apply
1.) Coughing involves a quick contraction of the diaphragm muscle, forcing air
through the respiratory pathway, and dislodging mucus or other harmful
particles
2.) Alveoli transfer bacteria and viruses to the bloodstream to be disposed of.
3.) Cilia function like a filter, trapping dust and pollen in the nose,
4.) Mucus traps bacteria and viruses to be removed or swallowed.
Answer:

3.) Cilia function like a filter, trapping dust and pollen in the nose,
4.) Mucus traps bacteria and viruses to be removed or swallowed.
Explanation:
Coughing involves a quick contraction of the diaphragm muscle, forcing air out while the cilia act like a filter, trapping dust and pollen in the nose. Mucus traps bacteria and viruses to remove or swallow. So, the correct options are A, C and D.
What is Respiratory system?The respiratory system is defined as the network of organs and tissues that help us breathe which includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system where these parts work together to move oxygen throughout the body and clear out waste gases like carbon dioxide.
Respiratory system works in that way with the immune system by keeping the human from getting sick by bacteria and viruses are removed or swallowed by mucus, while the cilia act like a filter, trapping dust and pollen in the nose.
Thus, coughing involves a quick contraction of the diaphragm muscle, forcing air out while the cilia act like a filter, trapping dust and pollen in the nose. Mucus traps bacteria and viruses to remove or swallow. So, the correct options are A, C and D.
