Answer:
b. typify a population in which all ages have an equal chance of surviving. → YES
e. are typical of annual plants → YES
Explanation:
Different species have survival curves differently shaped. In general terms, there are three different survival curves.
- Type I. Mortality often occurs at the end of the cycle, representing species with low mortality. Organisms exhibiting this type of survivorship curve have long cycles of life and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.
- Type II. The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offsprings, and they ensure their reproductive success by providing some significant parental care.
- Type III. Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life. These species produce big offsprings at the same time, but they provide little or no parental care. Their reproductive success relies on the number of descendants.
Type II survivorship curves:
a. are characteristic of humans and elephants → No, this is Type I curve
b. typify a population in which all ages have an equal chance of surviving. → YES
c. indicate a high mortality rate in the very young. → No, this is Type III curve
d. show that very few young are produced, that each is given parental support, and that most individuals live a relatively long life and die of old age. → No, this is Type I curve
e. are typical of annual plants → YES
The reliability of the information can be described as good because it is based on "<span>multiple research papers done by scientists at veterinary schools". There are two main points that make of the information a reliable one. Firstly, the researches were carried by scientists at veterinary schools, in other others, experts in the matter. And secondly, the information was based in multiple, not just one or a few, research papers that in order to be published are revised and only then accepted for publication. </span>
-if it is a website, look for .gov.
-look for direct facts, never trust opinions.
-they must have cited evidence, if its not cited it can't be trusted.
Answer:
b. cobalt, iron, and nickel
Explanation:
Answer:
Option C, It mandates the clean-up of abandoned hazardous waste sites.
Explanation:
A superfund was a programme launched by federal government in America to clean up hazardous and abandoned waste sites. The different sites that are managed under this programme are called as superfund scheme. It is also known as "Comprehensive Environmental Response, Compensation, and Liability Act, 1980"
Based on the hazardous ranking evaluated by the EIA team, CERCLA status of the site is determined . The site with highest score was dealt on priority basis.
Hence, option C is correct.
