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>

Answer:
2 molecules of ATP
Explanation:
Glycolysis is the anaerobic process (no oxygen required) used in the breakdown of glucose to extract energy. It occurs in the cytoplasm of both prokaryotic and eukaryotic cells. It is the first step of cellular respiration.
Glycolysis is subdivided into two phases: the first phase uses energy (ATP), while the second phase produces it together with pyruvate and NADH.
Two molecules of ATP are required for the first stage of glycolysis, while 4 ATP molecules and 2 NADH molecules are formed in the second stage.
Answer:
While skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles, called intercalated discs. Striated muscle contracts and relaxes in short, intense bursts, whereas smooth muscle sustains longer or even near-permanent contractions.
Primary succession: <u>is a process by which a community arises in a virtually lifeless area with no soil. </u>
Secondary succession:<u> follows a disturbance that destroys a community without destroying the soil.</u>
Answer:
Earth's outer core is a fluid layer about 2,400 km thick
Explanation:
composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km beneath Earth's surface
