Answer:
The C horizon is located closest to the Earth's crust. Weegy
Soil is made of air, water, organic material, minerals, and weathered rock.
Answer:
Plants need carbon dioxide , water and sunlight to make their own food. if the plant does not get these things, the plant will stop converting carbon dioxide and air pollutant to organic material
Explanation:
Answer:
C. Beak size is an inherited trait in the finch population under study.
D. Birds that could eat larger, tougher seeds survived and reproduced during the drought.
E. Beak size varies among the birds in the finch population under study.
Explanation:
The presence of genetic variations among the individuals of a population is required for natural selection to be operative. Natural selection targets the beneficial genetic variations present in the population. Natural selection refers to the differential reproductive and survival success of organisms of a population due to some beneficial genetic traits. These organisms with beneficial genetic traits are able to survive and leave more progeny under prevailing conditions.
If the natural selection has occurred in the ground finch population for the beak size, the beak size should be a genetic trait since natural selection works on genetic traits only. The finch population should have variations with respect to the beak size. The finches having the larger beak size that enabled them to feed on larger, tougher seeds should have higher survival and reproductive fitness during the drought.
Under these conditions, natural selection would favor the finches with larger beak size and would eventually result in an increase in the average beak size of the future generations.
Claim: the mean resting pulse rate for men is less than 72
bpm.
Symbolic form would be: μ < 72
Step 1: null hypothesis : μ > = 7 2 b p m
Step 2: alternative hypothesis: μ < 7 2 b p m
Step 3: the test statistic is z = mean – μ / standard dev/sqrt (n) = -3/4 / 1.7639 = -1.92
Step 4: c v method: since z α = -1.645, the test static is z = -1.92 is less than the CV, we reject null hypothesis
P Value method: area is 0.0274, since the p value is <= α, reject null hypothesis.
Step 5: the sample data support the claim that the mean resting pulse rate for men is less than 72 bpm.
<h2>Answer is "True" Generate a new hypothesis</h2>
Explanation:
- Due to the false hypothesis a student create a new hypothesis for the research.the hypothesis gives the objective to the research and the methodology to complete the work.
- If the student doesn't generate the correct the methodology hence, its work is not proficient to the research that's why the student try to do new analysis with new ideas.
- This is because the hypothesis is a conditional explanation about the connection between at least two factors. It is a particular, testable expectation about what you hope to occur in an investigation. For instance, an investigation intended to take a gander at the connection between lack of sleep and test execution may have a hypothesis that expresses, "This examination is intended to evaluate the theory that restless individuals will perform more awful on a test than people who are not sleepless.
- So, the right answer is true "Generate a new hypothesis" is the next step.
