Answer the following question given this paragraph: Determining recombination frequencies between genes located on the same chromosome allows a linkage map to be developed. Linkage mapping is critical for identifying the location of genes that cause genetic diseases. Q: What type of mapping is critical for identifying the location of genes that cause genetic diseases? Choices: - interaction mapping - diagnostic mapping - chemical mapping - linkage mapping A:
linkage mapping

Answer the following question given this paragraph: In science, motion is defined as a change in position. An object's position is its location. Besides the wings of the hummingbird in the opening image, you can see other examples of motion in the Figure below . In each case, the position of something is changing. Q: In science, what is defined as a change in position? Choices: - gravity - speed - direction - motion A:
(Answer)
motion
Ques: Answer the following question given this paragraph: Plants don't have immune systems, but they do respond to disease. Typically, their first line of defense is the death of cells surrounding infected tissue. This prevents the infection from spreading. Many plants also produce hormones and toxins to fight pathogens. For example, willow trees produce salicylic acid to kill bacteria. The same compound is used in many acne products for the same reason. Exciting new research suggests that plants may even produce chemicals that warn other plants of threats to their health, allowing the plants to prepare for their own defense. As these and other responses show, plants may be rooted in place, but they are far from helpless. Q: What do willow trees produce to kill bacteria? Choices: - chlorophyll - enzymes - cytoplasmic acid - salicylic acid A:
Ans: salicylic acid

Answer the following question given this paragraph: When humans reproduce, there are two parents involved. DNA must be passed from both the mother and father to the child. Humans cannot reproduce with just one parent; humans can only reproduce sexually. But having just one parent is possible in other eukaryotic organisms, including some insects, fish, and reptiles. These organisms can reproduce asexually, meaning the offspring ("children") have a single parent and share the exact same genetic material as the parent. This is very different from reproduction in humans. Bacteria, being a prokaryotic, single-celled organism, must reproduce asexually. Q: What type of reproduction produces offspring from a single parent that share the exact same genetic material as the parent? Choices: - mutation - microscopic reproduction - sexual reproduction - asexual reproduction A:
(A).
asexual reproduction
Ques:Answer the following question given this paragraph: Q: Which antibacterial protein is found in tears and saliva? Choices: - human growth hormone - amino acid - dopamine - human lysozyme A:

Ans:human lysozyme
Ques: Answer the following question given this paragraph: Molecules within a liquid are pulled equally in all directions by intermolecular forces. However, molecules at the surface are pulled downwards and sideways by other liquid molecules, but not upwards away from the surface. The overall effect is that the surface molecules are pulled into the liquid, creating a surface that is tightened like a film. This phenomenon is referred to as surface tension . Liquids that have strong intermolecular forces, like the hydrogen bonding in water, exhibit the greatest surface tension. Table below shows surface tension values for various common liquids. Q: Surface tension is a property of matter that is in what state? Choices: - mixture - water - Base - liquid A:
Ans:
liquid
