Part 4 - Natural Selection and Adaptations3 of 113 of 11 ItemsItem 3A scientist studied a snail population that had a variation of shell colors. The number of each differently colored snail shell was recorded. The graph shows the data the scientist collected.Over time, the rocks on which the snails lived became covered with dark-colored seaweed.Which graph best represents the range of colors in the snail population that resulted from natural selection after the dark-colored seaweed covered the rocks?

You are a new hire at a bioinformatics company and are helping to annotate the genome of a recently sequenced organism. A co-worker indicates that the software used to detect potential genes finds protein-coding genes more easily than genes for noncoding RNAs. What difference between coding and noncoding genes explains why genes coding for proteins are easier to identify than genes for noncoding RNAs

Students studying potential and kinetic energy designed this experimental set-up. During the initial trial, a ball was rolled down a ramp fro the spot marked "start". The ball rolled down the ramp and then back up the other side, to the spot marked "finish", represented by letter B. The students want to determine the starting point so that the ball will rise up to the point marked by letter A. They release the ball starts at the spot marked "New start" and the ball rolls up the other side to letter A.This is a controlled experiment. All BUT ONE factor is controlled in this experiment. What is that factor?A. ball used in trialsB. distance between rampsC. starting point of releaseD. angles of incline for ramps ***Can someone check this?

The Rock CycleSelect the incorrect statements by clicking on the sentences.aryLEEThe rock cycle describes the way that rock material cycles through Earth's crust. Allrocks start out as lava or magma that cools into igneous rock. An igneous rock must thenbe weathered into sediments for the next stage of the cycle. Sediments are compressedand cemented to become sedimentary rock. Metamorphic rock forms when rocks areheated and squeezed deep in Earth's crust. New igneous rock forms when metamorphicrock is heated so much that it melts into magma, which cools into igneous rock. All rocksgo through this cycle over and over again.Resultsbo...CloyLanguage..

Southern Florida has many tropical hardwood hammocksforest habitats that are warm, wet, and populated with many broad-leaved evergreen trees. Why might a plant native to an ecosystem with a cooler climate do well if introduced to a tropical hardwood hammock? Group of answer choices The trees in the tropical hardwood hammock are better at competing for native resources than the introduced species are. The wet conditions in the tropical hardwood hammock disrupt the life cycle and limit reproduction of the introduced species. Freezing temperatures that normally limit the population in the cooler climate are lacking in the tropical hardwood hammock. Pollinators and seed carriers that normally increase the population in the cooler climate are lacking in the tropical hardwood hammock.

Two students completed an experiment to determine if pesticide use at local farms was causing fish kills in a local pond. The steps of the experiment are listed below. Select one location to collect water samples in the pond. Collect a 5-mL water sample at 8 am for two days. Measure the amount of pesticide present in each sample using the same measurement tools. After analyzing their data, the students conclude that pesticide runoff from farms is not causing the fish to die in the pond. Which of these statements best describes why their conclusion is not reliable? The pesticide measurements were the dependent variable. The samples were collected at different times. The samples were only collected for two days. The time of sample collection was not an independent variable.

Victor has been studying the vascular systems of plants. He wanted to find out if food coloring would travel up the stalk of celery faster if the temperature of the water increased. Victor set up his experiment with three cups of colored water at different temperatures, three equal sized celery stalks, and a stopwatch. Cup A was filled with colored water at 21 C. Cup B was filled with cold colored water at 4 C, and Cup C was filled with warm colored water at 30 C. One celery stalk was placed in each cup at the same time. Victor timed how long it took the colored water to travel to the leaves at the top of the celery stalk. He measured the time in minutes. What is the independent variable

Water has a variety of unique properties, including a low melting point, ability to dissolve other substances, and strong adhesion and cohesion. Which statement is MOST useful for explaining the unique properties of water? A. Water molecules are nonpolar, so a very minimal electrical force attracts them to one another. B. Water molecules may sometimes gain or lose an oxygen atom to become ions, which are held together by ionic bonds. C. Water molecules are held together by hydrogen bonds, which are attractive forces stronger than ionic bonds. D. Water molecules are held together by hydrogen bonds, which are attractive forces weaker than covalent bonds.

To protect our rights, the Constitution divides powers between the federal government's branches. This principle is called "separation of powers." Each branch of government holds distinct but equal authority. For example, Congress has the power to create laws, while the president has the power to execute these laws. The preamble states the purpose of "securing the Blessings of Liberty." Our freedoms are secured when power is not concentrated in any single branch of government. This helps our government to provide for our needs while respecting our rights.

Pasteur used swan-neck flasks in his experiments to test the validity of spontaneous generation. Suppose that after allowing the flasks to sit for a day, he had tilted one of these flasks so that the sterile broth entered the swan neck. Suppose he had then tilted the flask back to allow the broth to settle back into the round bowl of the flask before leaving it to sit undisturbed for another few days. What would have happened, and how would these results have affected conclusions about spontaneous generation?
