Species strategies to survive and successfully reproduce define three basic survivorship curves. <em>The survivorship curve </em><em>type III</em><em> is the one that best represents the Dandelion plants.</em>
------------------------------
According to the species strategies to survive, reproduce, and ensure their reproductive success, we can mention three basic curves,
<u>Type I.</u>
- Mortality often occurs at the end of the cycle, representing species with low mortality.
- Organisms exhibiting this type of survivorship curve have long life cycles 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.
<u>Type II.</u>
- 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 offspring, and they ensure their reproductive success by providing some significant parental care.
<u>Type III.</u>
- 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 large offspring at the same time, but they provide little or no parental care.
- The reproductive success of these species depends on the number of descendants and not on the parenting time spent.
According to this information, and the characteristics of the <em>Dandelions, we might assume that this species is represented by type III curve.</em>

A and B. Because if heart cells were located in your brain, your brain would not perform the right function. And B because if cells perform different functions and are in the wrong spot im your body it wouldnt work.
Hi! human,dog are multicellular organisms. Nucleus,cell membrane, cytoplasm and mitochondria are 4 things that plant and animal cells have.
Following general conditions are necessary for natural selection to occur in population:
- More organisms are born than can survive.
- Organisms vary in their characteristics, even within a species.
- Differences in reproduction and survival are due to variation among organisms.
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Galapagos Finches: The Galapagos finches studied by Darwin on his famous voyage are probably the most common example of natural selection.
Structurally, DNA and RNA are nearly identical. As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
