Answer: Anything living needs to have certain conditions, if for example a group of flightless birds who are adapted for warm weather had their environment get colder each year and more extreme the surrounding plants and other animals may have a difficult time surviving and this will cause the birds to have less food. The birds also will not be accustomed to these changes and will not be able to adapt their bodies fast enough. This also makes reproduction difficult and in turn further dwindles the population.
Hope this helps!
Explanation:
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.

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.
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:
1.) Coughing involves a quick contraction of the diaphragm muscle, forcing air
through the respiratory pathway, and dislodging mucus or other harmful
particles
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.

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.

Sexual reproduction in animals depends on the production of gametes.
Which of these processes produces gametes in animals? *
Mitosis
Fertilization
O Meiosis
Binary fission
The process that produces gametes in animals is meiosis.
What is MeiosisMeiosis is a specialized type of cell division that occurs in the reproductive cells, or germ cells, of animals. It involves two rounds of cell division, resulting in the production of four haploid daughter cells, each with half the number of chromosomes as the parent cell.
During meiosis, the genetic material is shuffled and recombined through processes such as crossing over and independent assortment. This genetic variation contributes to the diversity of offspring produced through sexual reproduction.
