Because it’s more likely that chance events will significantly change the frequencies of alleles in the population
Imagine you are surveying a population of a mountain range where the inhabitants live in the valleys with no inhabitants on the large mountains between. If your sample area is the valleys, and you use this to estimate the population across the entire mountain range, <u>you overestimate the actual population size</u>
<u />
Explanation:
- An estimate that turns out to be incorrect will be an overestimate if the estimate exceeded the actual result, and an underestimate if the estimate fell short of the actual result.
- The mean of the sampling distribution of a statistic is sometimes referred to as the expected value of the statistic. Therefore the sample mean is an unbiased estimate of μ.
- Any given sample mean may underestimate or overestimate μ, but there is no systematic tendency for sample means to either under or overestimate μ.
- Bias is the tendency of a statistic to overestimate or underestimate a parameter. Bias can seep into your results for a slew of reasons including sampling or measurement errors, or unrepresentative samples
<span>It is True - Sand that extends from a coast into open water is called a barrier spit.
Barrier spits are formed when there is a deposit on the shoreline due to the lateral movement of water.
The waves are known to hit the shoreline at a particular angle which cause the lateral movement of water accompanied with the sedimentation along the coastline in the direction of the wave motion.</span>
Answer:
The correct answer will be- light independent reaction or Calvin cycle
Explanation:
The process of photosynthesis takes place in the two phases: light-dependent and light-independent phase.
The light-dependent phase form NADPH and NADPH which are utilized during the light-independent phase to synthesise glucose molecule.
The light-independent phase occurs in the cytosol or stroma of the chloroplast in dark conditions which help synthesize the glucose molecules. The light-independent reaction is also known as the Calvin cycle which forms the glucose molecules in three steps- carboxylation, reduction and regeneration.
Thus, the Calvin cycle is the correct answer.
Answer:
Primary reinforcer is innate, secondary reinforcer is a stimulus
Explanation:
While a primary reinforcer is innate, a secondary reinforcer is a stimulus that becomes reinforcing after being paired with a primary reinforcer, such as praise, treats, or money.
Hope this helps!
