Answer the following question given this paragraph: Linked Genes Violate the Law of Independent Assortment Although all of Mendel's pea characteristics behaved according to the law of independent assortment, we now know that some allele combinations are not inherited independently of each other. Genes that are located on separate nonhomologous chromosomes will always sort independently. However, each chromosome contains hundreds or thousands of genes, organized linearly on chromosomes like beads on a string. The segregation of alleles into gametes can be influenced by linkage, in which genes that are located physically close to each other on the same chromosome are more likely to be inherited as a pair. However, because of the process of recombination, or "crossover," it is possible for two genes on the same chromosome to behave independently, or as if they are not linked. To understand this, let's consider the biological basis of gene linkage and recombination. Homologous chromosomes possess the same genes in the same linear order. The alleles may differ on homologous chromosome pairs, but the genes to which they correspond do not. In preparation for the first division of meiosis, homologous chromosomes replicate and synapse. Like genes on the homologs align with each other. At this stage, segments of homologous chromosomes exchange linear segments of genetic material (Figure 12.18). This process is called recombination, or crossover, and it is a common genetic process. Because the genes are aligned during recombination, the gene order is not altered. Instead, the result of recombination is that maternal and paternal alleles are combined onto the same chromosome. Across a given chromosome, several recombination events may occur, causing extensive shuffling of alleles. Q: How do genes located on separate nonhomologous chromosomes sort? A:

OPTIONS:
- mechanically
- intradependently
- typically
- independently

Answer: independently

Problem: OPTIONS:
- local animals
- local weather
- random chance
- problems of society
Q: Answer the following question given this paragraph: The goal of technology is to solve people's problems. Therefore, the problems of society generally set the direction that technology takes. Technology, in turn, affects society. It may make people's lives easier or healthier. Two examples are described in Figure below . Q: What generally sets the direction that technology takes? A:
Answer: problems of society

Problem:OPTIONS:
- lungs
- phototropism
- pores
- gills

Answer the following question given this paragraph: Which of the following statements about the anatomy of a mollusk is false? a. Mollusks have a radula for grinding food. A digestive gland is connected to the stomach. The tissue beneath the shell is called the mantle. The digestive system includes a gizzard, a stomach, a digestive gland, and the intestine. Mollusks have a muscular foot, which is used for locomotion and anchorage, and varies in shape and function, depending on the type of mollusk under study. In shelled mollusks, this foot is usually the same size as the opening of the shell. The foot is a retractable as well as an extendable organ. The foot is the ventral-most organ, whereas the mantle is the limiting dorsal organ. Mollusks are eucoelomate, but the coelomic cavity is restricted to a cavity around the heart in adult animals. The mantle cavity develops independently of the coelomic cavity. The visceral mass is present above the foot, in the visceral hump. This includes digestive, nervous, excretory, reproductive, and respiratory systems. Mollusk species that are exclusively aquatic have gills for respiration, whereas some terrestrial species have lungs for respiration. Additionally, a tongue-like organ called a radula, which bears chitinous tooth-like. Q: What do aquatic mollusk species use for respiration? A:
****
A: gills

Answer the following question given this paragraph: Predator species such as birds and spiders control insect pests. They reduce the need for chemical pesticides, which are expensive and may be harmful to human beings and other organisms. Q: Predators can replace what tool in agriculture. A:
OPTIONS:
- harvesters
- fertilizer
- irrigators
- pesticides
pesticides

Answer the following question given this paragraph: The length traveled by an object moving in any direction or even changing direction is called distance. Q: The length that an object has travelled in one or multiple directions can also be called what? A:
OPTIONS:
- axis
- velocity
- range
- distance

Answer: distance

input with options: Answer the following question given this paragraph: Mutualism is a symbiotic relationship in which both species benefit. An example of mutualism is pictured in Figure below . The clownfish in the photo is hiding among the tentacles of a sea anemone. The tentacles have stingers that can inject poison in the anemone's prey. The clownfish is protected from the stingers by mucus that covers its body. Q: Mutualism is a symbiotic relationship in which both species do what? A:
OPTIONS:
- die
- suffer
- reproduce
- benefit
output:
benefit
