I’m sorry can u translate it to english!
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>

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

Answer:
The rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction, Vmax. ... This is usually expressed as the Km (Michaelis constant) of the enzyme, an inverse measure of affinity. For practical purposes, Km is the concentration of substrate which permits the enzyme to achieve half Vmax.

Answer:
1. A Struggle for Survival
2. survival will reproduce
3. Superior adaptive variation
Explanation:
1. Observation: overproduction of offspring that can possibly survive.
CONCLUSION: A Struggle for Survival, most of this offspring fight for food and water.
2. Observation: variation in species: member of the same species have different ways of identification, which are color, sex, e.t.c
CONCLUSION: Those individuals that survive and reproduce do so in consequence of "superior adaptive variation" (they are "more fit")
3. Observation: Variation heritable through selection: most survival pass there favourable adaptation to their offspring.
CONCLUSION: Superior adaptive variation will be passed on to offspring generation.
