The other six islands in the study remained free of L. Negative Data Analysis: HHMI Data Point Resource Understanding how data is collected, organized, displayed, analyzed, and communicated is part of the scientific process. Reef-building corals are sensitive to heat and can bleach when they experience temperatures above the normal range for their given location for a prolonged period of time. Normally, an allele can be used to produce a protein, such as p53. Declines are measured as the number and percentage of species that declined per 10,000 km2 area. In contrast, the continent contains no known shrew or The data represent 996 suspected, probable, or confirmed cases of EVD documented during the seven Ebola outbreaks that occurred between 1975-2014 and the background population from 1976-2010. The researchers collected data on the lizard community on each of the islands, including Z3, until 1999. Their study site, a remote cave located within Carlsbad Caverns National Park in New Mexico, called Lechuguilla Cave, was estimated to have been isolated from human contact and surface contamination (such as The researchers later went on to explore how the eradication of rinderpest, and the rise in wildebeest numbers, affected other species in the ecosystem. Caption: The data points represent the estimated stature (height) of hominin individuals based on fossilized remains or footprints. Because males can produce many more sperm than females can produce eggs, males and females usually evolve different strategies for increasing reproductive success. Some of these strategies involve mate choice, or Role of p53 in the Cell Cycle Student Handout In this study, researchers investigated the role of p53 in cell cycle regulation at the checkpoint between the G2 and M phases. Maternal Microbiota Impacts Offspring Immune System Student Handout In this study, scientists compared the offspring of two groups of mice, one in which the mothers were kept germ-free throughout pregnancy, and the other in which the mother was germ-free before the pregnancy and was exposed to a strain of E. The scientists searched for an ortholog (a corresponding gene of similar sequence and function) of the golden gene in humans. Muscle cells, neurons, and electric organs all use sodium channel proteins to generate action potentials. Each projection was simulated for up to 100 years after the disease emerged in the population. Each global map depicts the number of species in a given mammal clade known to carry at least one zoonotic disease. docx from Science 34435 at Federal Institute of Bahia-.

The key chromosome region The p53 protein, referred to as the “Guardian of the Genome,” is a tumor suppressor that plays an important role in halting the division of cells (mitosis) that have sustained DNA damage. They found that larger wildebeest populations consumed more grass, which in turn reduced the wildfires in the region. This interactive module explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, replication cycles, and vaccine availability.

To determine the genetic mutations responsible for stickleback pelvic reduction and loss, and to explain how these changes arose separately in different populations, scientists looked for genetic changes in a chromosome region that controls most of the differences in pelvis size when marine and freshwater sticklebacks are crossed with each other in the laboratory. , birds) that the compiled data for all vertebrates cannot show you? Use evidence from the map to support or refute the claim that bird species account for the pattern of vertebrate declines we see in the Amazon and in Southeast Asia. Fast pulses or waves of action potentials can be produced by certain types of fish, called electric fish. Scientists expect that climate change will cause droughts and sea level rise, both of which could increase salinity in some parts of the world. Ecology Revised September 2017 www.

Real science, real stories, and real data to engage students in exploring the living world. However, electric organs can generate action potentials much faster than normal muscle cells and neurons can. These probabilities were projected for five annual rates of population decline (45%, 20%, 10%, 5%, or 2%) under an infectious disease called white-nose syndrome (WNS). The closest match was a gene called SLC24A5. The The researchers plotted data from previously published studies to determine whether tissues with a greater number of stem cell divisions (and therefore a greater amount of DN! replication) over a person’s lifetime is related to the overall risk of cancer in that tissue.
