Selective breeding on food crops may create stronger, and more healthy crops. The idea is to find your best crops, and breed them with other crops sharing the traits you want. Selective breeding can make crops produce more matter that is edible, grow taller, grow shorter, etc.. W<span>eaker crops, or crops that have undesirable traits will slowly disappear, and eventually the gene pool will mostly have the selected crop</span>
Answer:Plants use carbon dioxide to make food
Explanation: Carbon-dioxide plays a very important role in sustaining life on Earth.
Plants use carbon-dioxide and water for photosynthesis in presence of sunlight and chlorophyll to produce food and oxygen.
CO₂ + H₂O → O₂ + glucose (food)
This food is consumed by the animals and oxygen is used for respiration. Animals use energy from the food to do work and exhale back carbon-dioxide.
Answer & explanation:
A confidence interval is an estimated range of a parameter of interest. Confidence intervals are used to indicate the reliability of an estimate. For example, a confidence interval can be used to describe how reliable a search result is.
In other words, a high confidence interval Z value implies that a survey is more likely to indicate the actual values being presented.
In biostatistics, for example, the Z value can be used in calculations to assess the prevalence of a particular disease and the factors associated with it in a population.
The value of Z, however, is not used as a percentage (like the 99.5% addressed in this question) for calculations. A universal table is used to convert Z values and use them in statistical calculations.
Some examples of Z value conversions can be found in the table attached in this question.
I don't know if this is right but I think B: three times or its probably more than 3 times bc of these hurible people in this world!
Answer:
Xylem transfers water up from the roots to the leaves.
Phloem transfers sugars (glucose) produced in the leaves down to the roots to be stored.
