Answer the following question given this paragraph: A solution is a homogeneous mixture with tiny particles. An example is salt water. The particles of a solution are too small to reflect light. As a result, you cannot see them. That's why salt water looks the same as pure water. The particles of solutions are also too small to settle or be filtered out of the mixture. Q: A homogeneous mixture with tiny particles in it is known as what? Choices: - element - plasmid - structure - solution A:
(Answer)
solution
Ques: Answer the following question given this paragraph: Many pathogens that cause respiratory diseases spread by droplets in the air. Droplets are released when a person sneezes or coughs. Thousands of tiny droplets are released when a person sneezes ( Figure below ). Each droplet can contain thousands of pathogens. Viruses that cause colds and the flu can spread in this way. You may get sick if you breathe in the pathogens. Q: How many pathogens can each droplet contain? Choices: - tens - billions - hundreds - thousands A:
Ans: thousands
(Q).
Answer the following question given this paragraph: The retina is a membrane lining the back of the eye. The retina has nerve cells called rods and cones that change images to electrical signals. Rods are good at sensing dim light but can't distinguish different colors of light. Cones can sense colors but not dim light. There are three different types of cones. Each type senses one of the three primary colors of light (red, green, or blue). Q: What do you call the membrane lining the back of the eye? Choices: - cornea - stimulation - aperture - retina A:
(A).
retina
Ques:Answer the following question given this paragraph: Q: A largemouth bass is an example of a cold-blooded animal that conforms to what aspect of the lake it inhabits? Choices: - depth - precipitation - oxygen - temperature A:

Ans:temperature
Answer the following question given this paragraph: Unfortunately, maternal mt(DNA)is susceptible to mutations which are a cause of inherited disease, such as breast cancer. Although, it is important to note that most mutations do not lead to defected mtDNA. Heteroplasmy is the presence of a mixture of more than one type of mtDNA. Most people have homoplasmic cells, meaning that their cells contain only normal, undefected mtDNA. However, people with both normal, undefected mtDNA and not normal, defected mtDNA, may inherit mitochondrial diseases. The ultimate condition leading to disease is when the proportion of mutant mtDNA reaches a threshold, after which the cell can no longer cope, resulting in disease. This threshold varies among different tissues and different mutations. Q: What increases the chances of someone inheriting a mitochondrial disease? Choices: - presence of defect transgenic and defect mtdna - presence of defect transgenic and undefected mtdna - presence of defect ornithopods and undefected mtdna - presence of defect mtdna and undefected mtdna A:
presence of defect mtdna and undefected mtdna
