Answer:
16. Control group: Subject A
17. Independent (manipulated) variable: Type of powder
18. Dependent variable: Itching time
19. Explain whether the data supports the advertisement´s claims about its product. Yes, it does.
Explanation:
Control group: The control group is used to identify if there are any other factors influencing the results obtained by the treatment in the study (in this case, the new product), from the results that might be a consequence of other factors. The control group must be selected from the same population as the treatment group. Data from an experimental group are compared with the data from a control group. These two groups are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals.The experimental group is the one that receives the experimental procedure, with changes in the independent variable. There can be several experimental groups. In this case, the experimental group is subject B.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the type of powder is the independent variable. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, inching time is the dependent variable, that depends on the type of powder used. The data does support the advertisement´s claims about its product. The effect of the new product lasts 50% more than the original product. The old powder produced itching for 30 minutes, while the new product produced itching for 45min (15 more minutes, 50% more).wha is the capital of the united states

Nitrogen-fixing bacteria making
nitrogen available for use by other
organisms to utilize is an example
of..
A. mutualism.
B. commensalism.
C. decomposition
The nitrogen fixation bacteria makes the nitrogen available for the plants directly into the soil. This is an example of mutualism, where both bacteria and organisms are benefited.
Most leguminous plants like peas, bans, and cloves have colonies of nitrogen fixation bacteria. These bacteria are found attached to the roots nodules and tend to fix the nitrogen. Through this, the bacteria gain sugar from the plant.Hence mutualism is the end product of the interaction. This option A is correct.

Explanation:
how sexual reproduction plays its role in avoiding genetic monotomy
Answer:
Abstract
The relative contributions of sexual and asexual reproduction to the genetic structure of populations can be difficult to determine for fungi that use a mixture of both types of propagation. Nuclear RFLPs and DNA fingerprints were used to make indirect and direct measures of departures from random mating in a population of the plant pathogenic fungus Mycosphaerella graminicola during the course of an epidemic cycle. DNA fingerprints resolved 617 different genotypes among 673 isolates sampled from a single field over a 3-month period. Only 7% of the isolates represented asexual clones that were found more than once in the sample. The most common clone was found four times. Genotypic diversity averaged 85% of its maximum possible value during the course of the epidemic. Analyses of multilocus structure showed that allelic distributions among RFLP loci were independent. Pairwise comparisons between individual RFLP loci showed that the majority of alleles at these loci were in gametic equilibrium. Though this fungus has the capacity for a significant level of asexual reproduction, each analysis suggested that M. graminicola populations maintain a genetic structure more consistent with random-mating over the course of an epidemic cycle.
When you exercise or sunbathe, you sweat. that sweat eventually evaporates. Why does this occur
Answer:
The sweat leaves your skin through tiny holes called pores. When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down.

Very large, massive stars burn their fuel much ___________ than smaller stars.
Answer:
Very large, massive stars burn their fuel much faster than smaller stars. Their main sequence may last only a few hundred thousand years. Smaller stars will live on for billions of years because they burn their fuel much more slowly. Eventually, the star's fuel will begin to run out.
What would happen if I poured a glass of water into a beaker with 90% clay and 10% sand? Would the water rush through the soil or would it move slowly through the soil? Please explain your answer.
Answer:
100 %
Explanation:
Answer:
It would move slowly
Explanation:
Clay is able to hold a large amount of water, sand, not so much. Because the majority of it is clay it shouldn't rush threw it. hope this helped

Classify photosynthesis and cellular respiration as endergonic or exergonic. Explain how you know.
Explanation:
photosynthesis is an endergonic process as it involves the absorbtion of energy (in the form of sunlight), while cellular respiration is an exergonic process as it involves the release of energy in the form of ATP molecules-the energy currency of the cell.

Which factors contribute to the way organisms grow and develop? Choose the three that apply. A. Genetics B. Size C. Response to stimuli D. Structures E. Access to resources
Answer:
a
Explanation:
The factors that are important for the growth of the organism are the genetics, the response to stimuli, and the access to resources that are present in options A, C, and E.
What are the factors needed for the growth of the organism?Organisms require certain conditions in order to grow, such as foods and nutrients; a source of energy and materials to build new cells and tissues, water, light, proper temperature, oxygen etc, and good health, as organisms that are diseased or injured may not be able to grow and function normally and after all, a suitable environment is needed that includes all these ,each organism has specific requirements for its habitat, such as the right temperature, humidity, and availability of resources and grow when they get it.
Hence, the factors that are important for the growth of the organism are the genetics, the response to stimuli, and the access to resources that are present in options A, C, and E.

if the egg of a particular butterfly has 14 chromosomes, how many chromosomes will be found in a somatic cell for this butterfly - PLEASE HELP DUE TONIGHT
Answer:
not
Explanation:
If the egg of a particular butterfly has 14 chromosome, then the somatic cells will have same 14 chromosomes.
What are somatic cells?A somatic cell, also known as a vegetal cell, is any biological cell other than a gamete, germ cell, gametocyte, or undifferentiated stem cell that forms the body of a multicellular organism.
These cells make up the body of an organism and divide via binary fission and mitotic division.
Mitosis is a cell division process that produces somatic cells. They have two copies of each chromosome, one from the mother and one from the father. Diploid cells usually have two copies each of each chromosome.
Mitosis is the method by which one cell splits into two genetically identical daughter cells.
The cell's chromosomes are copied and then distributed evenly between the two new nuclei of the daughter cells during the various stages of mitosis.
Thus, as these are somatic cells, they will have same number of chromosomes.
