earth science

Q: What can lead to a loss of genetic variation within populations? Read this paragraph and choose the correct option from the provided answers: Choices: - migration - adaptation - natural selection - genetic drift A:
genetic drift

Q: Q: What is the term for a symbiotic relationship in which one species benefits while the other species is not affected? Read this paragraph and choose the correct option from the provided answers: Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. An example is the relationship between birds called cattle egrets and cattle (see Figure below ). Cattle egrets feed on insects. They follow cattle herds around to take advantage of the insects stirred up by the feet of the cattle. The egrets get ready access to food from the relationship, whereas the cattle are not affected. Choices: - parasitism - mutualism - pollenation - commensalism A:
A: commensalism

Question: Q: Deletions remove one or more what from the dna? Read this paragraph and choose the correct option from the provided answers: Similar to chromosomal alteration mutations, deletion or insertion mutations add or remove genetic information. Small deletions or insertions in the DNA will alter the reading frame. Deletions remove one or more nucleotides from the DNA, whereas insertions add one or more nucleotides into the DNA. These mutations in the coding region of a gene may also alter the splicing of the mRNA, known as a splice site mutation . Mutations which alter the reading frame are known as frameshift mutations . Splice site mutations and frameshift mutations both can dramatically change the mRNA, altering the final protein product. Choices: - codons - exons - genes - nucleotides A:
Answer: nucleotides

Q: What do scientists attach to aquatic animals to collect information? Read this paragraph and choose the correct option from the provided answers: Beginning in 2000, scientists from the National Oceanic and Atmospheric Administration, Stanford University, and the University of California, Santa Cruz combined to form TOPP. As part of TOPP, researchers attach satellite tags to elephant seals, white sharks, giant leatherback turtles, bluefin tuna, swordfish, and other marine animals. The tags collect information, such as how deep each animal dives, the levels of ambient light (to help determine an animal's location), and interior and exterior body temperature. Some tags also collect information about the temperature, salinity, and depth of the water surrounding an animal to help scientists identify ocean currents. The tags send the data to a satellite, which in turn sends the data the scientists. They use this information to create maps of migration patterns and discover new information about different marine ecosystems. The information collected by TOPP offers rare insights into the lives of marine animals. Without TOPP, that information would otherwise remain unknown. With TOPP, scientists are developing a working knowledge of the particular migration routes animals take, as well as the locations of popular breeding grounds and the environmental dangers faced by different species. TOPP has shed light on how we can better protect the leatherback turtle and other endangered species. Choices: - ultraviolet tags - radio tags - fluorescent tags - satellite tags A:
**Answer**
satellite tags

Q: Which is the best way to maintain a strong, fit body? Read this paragraph and choose the correct option from the provided answers: Athletics are very competitive these days at all levels, from school sports to the pros. Everybody is looking for that edge that will make them faster, stronger, more physically fit. One approach taken by many athletes is the use of amino acid supplements. The theory is that the increase in amino acids in the diet will lead to increased protein for muscles. However, the only real benefit comes to the people who make and sell the pills. Studies have not showed any advantage obtained by the athletes themselves. You're much better off just maintaining a healthy diet. Choices: - bodybuilding - regular exercising - being a vegetarian - a healthy diet A:
**Answer**
a healthy diet
