Which problem would most likely occur if the mitotic spindle stopped functioning in a cell? There are different ways to think about vulnerability to weather and climate events. Federal assistance programs were able to help many farmers, but a longer-lasting drought would make it more difficult for the government to provide nationwide aid. As opposed to meteorological drought, which is a result of only weather and climatic conditions, hydrological drought is caused by lack of precipitation (rain and snow) over longer periods, and a greater demand for water in a given region than is available. There is still a lot of debate about the connection between droughtand global warming, the current period of climate change. This disruption can dramatically impact amounts of precipitation that a region normally receives. In most Sub-Saharan African countries: the fertility rate is ____, the death rate is ____, and life expectancy is ____.

"Beyond being of practical relevance to development practitioners and other policymakers, this work shows how much just one of the main effects of climate changemore severe and more frequent droughtswill impact especially children in poor countries, who have not contributed to the climate change problem themselves. Over-farming andovergrazingcan lead to soil beingcompacted and unable to hold water. Trees and other plants have adapted to withstand the effects of drought through various survival methods. Risk Reductionrefers to the application of appropriate techniques to reduce the likelihood of risk occurrence and its consequences. No need to shop around. In this study, researchers found that states ranking highest in overall vulnerability often had less to do with how frequently drought occurs, and more with how prepared the state is for drought impacts. The western United States has experienced periods of horrible droughts throughout history, and climate change is blamed for producing more extreme weather variations in many other regions. In the 1950s, severe drought returned to the Great Plains and southwestern United States, affecting half of the continental U.S. Low rainfall and high temperatures caused the production of crops in some areas to drop nearly 50 percent. Physical Vulnerabilitymay be determined by aspects such as population density levels, remoteness of a settlement, the site, design and materials used for critical infrastructure and forhousing (UNISDR).
