Answer: Photosynthesis uses the energy obtained from light to free electrons from the chlorophyll pigments that collect the light. In cellular respiration the electron transport chain occurs after glucose has already been broken down.
Explanation:
Answer:
The ecosystem is adversely affected.
Explanation:
The ecosystem is adversely affected due to clearing of all trees and bird population is also adversely affected because these trees are the source of habitat for these birds. When there is large number of birds in an ecosystem so the bird population automatically increases due to the presence of more habitat for the birds so if all the trees are removed so very little population of birds left in that ecosystem and this action leads to great disturbance in the ecosystem.
Answer:
The correct options are (c) and (d).
Explanation:
The assumptions made before using a <em>t</em>-distribution for a hypothesis test are:
- The scale of the data should be continuous or ordinal.
- The sample selected should be a simple random sample.
- The data selected should follow a normal distribution or form a bell-shaped curve when plotted.
- The sample selected must be large enough so that when plotted a normal distribution curve is formed.
- Homogeneous variance exists so that the standard deviations of the samples are approximately equal.
A sample size of 5 a sample size of 50 sample will not be accurate for a <em>t</em>-test because on of the sample size is, 5.
This sample size is very small and when plotted will not follow a normal distribution.
The sets that differed in variance will not be accurate for a <em>t</em>-test because for using a <em>t</em>-test homogeneity of variances is assumed.
Thus, the correct options are (c) and (d).
