What is a restriction in genetic variability caused by a drastic reduction in population size?
A reduction in population size can lead to a loss of genetic diversity, limiting the gene pool available for natural selection. This reduction in genetic variability can decrease the ability of a population to adapt to changing environments or withstand diseases. This is known as a genetic bottleneck.
What was developed in medicine in 1954?
In 1954, the Salk polio vaccine was developed, providing a breakthrough in the fight against polio, a debilitating and sometimes deadly disease. This vaccine was a significant milestone in public health, leading to a drastic reduction in polio cases worldwide.
How does the pH level of a pond affect native organisms?
The pH level of a pond can directly impact the survival and reproduction of native organisms. Slight changes in pH can disrupt the internal chemistry of organisms, affecting their growth, metabolism, and overall health. Many native species have adapted to specific pH levels, so drastic changes can lead to population declines or even extinctions.
What importance are buffers to living organisms?
Buffers play a crucial role in maintaining the stability of pH levels in living organisms. They help prevent drastic changes in pH by absorbing or releasing hydrogen ions. This is essential for normal biochemical processes to occur within a narrow pH range.
A change in relative frequencies of alleles in the gene pool of a population is called?
A genetic drift is a random change in allele frequency over time that is brought about by chances. A bottle neck is a drastic reduction in population size brought about by severe pressure.
What two things can organisms do in a response to a drastic change in the environment?
Organisms can either adapt to the change through physiological or behavioral adjustments or they can migrate to a more suitable environment where conditions are more favorable for survival. Both of these strategies help organisms cope with drastic environmental changes and increase their chances of survival.
Marine organisms that are well adapted to drastic changes in salinity would most likely be found in which environment?
Estuaries would be a likely environment for marine organisms well adapted to drastic changes in salinity, as estuaries experience fluctuations in salinity levels due to the mixing of freshwater from rivers and saltwater from the ocean. Organisms in estuarine environments have developed physiological mechanisms to tolerate these changes.
How does heating water help organisms in the environment?
Heating water can help organisms in the environment by increasing the rate of metabolism and biochemical reactions, which can be beneficial for some species. Warmer water can also improve nutrient availability and dissolve gases more easily, aiding in biological processes such as respiration. However, drastic or prolonged increases in water temperature can also harm organisms by disrupting ecosystems and stressing species that are not adapted to higher temperatures.
A drastic drop in the value of money coupled with a rise in prices?
When there is an increase in prices for good and services combined with a reduction in the value of money it is known as inflation.

A sentence with drastic in it?
Drastic times call for drastic measures. That was a rather drastic action, don't you think?
Do bearded dragons respond to the environment?
Yes they do. New things in their environment can stress them. Temp changes can cause brumation (a form of hibernation) and even cause sickness if too drastic.
A description of possible effects on the environment us if you were to lose some or all of the ozone layer?
The environment would see a drastic change. It would be because of ozone's ability to absorb UV.
What is the process of becoming adapted to the environment?
a model of evolution in which short periods of drastic change in species are separated by long periods of little or no change
What are significance of transportation?
It's as simple as that. Each settlement pattern is affected by transportation and a change in it can have a drastic impact on the ultimate viability of the built environment.

Will not eating make you gain weight Why?
Generally, if you stop consuming calories you will begin to lose weight. However, the human body reacts to a sudden, drastic reduction in caloric intake by making defensive changes in metabolism and the way it stores of fat. Also, drastic dieting often results in an irresistible urge to binge which can result in a net gain.
