Rachael wants to test how sunlight impacts plant growth over time. She will add varying amounts of light to different sets of plants. What is the independent and dependable variable?
Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
Q1.2. Suppose you decide to design an experiment
to test your friend's hypothesis about classical
music and studying. How will you define your
variables?
O. Both study music and test performance are
potentially confounding variables.
Independent variable: study music. Confounding
variable: test performance.
Independent variable: study music. Dependent
variable: test performance.
Independent variable: test performance.
Dependent variable: study music.
Answer:
The correct answer is :
Independent variable: study music.
Dependent variable: test performance.
Explanation:
Independent variable in a experiment is a variable or a factor that is manipulated or changed in a particular experiment to see its the effect on dependent variable of this change. In this case classical music is variable as it is manipulated to see if it has any effect on studying.
Dependent variable is a variable which is measured in experiment to find the result and affected by the independent variable. In this case testing the performance of subject is dependent variable as it is being measured and affected by classical music.
Thus, the correct answer is: Independent variable: study music.
Dependent variable: test performance.
during what stage of meiosis do daughter cells first become haploid?
Answer: Only after the first cytokinesis, when the daughter cells of meiosis I are fully separated, are the cells considered haploid. Following this first division, the cell begins meiosis II with prophase II, making this the first haploid meiotic stage.
Explanation:
The stage of meiosis is when the daughter cells first become haploid is meiosis I, after cytokinesis.
What is meiosis?Meiosis is a process of cell division that occurs only in germ cells, during the process of reproduction. It is divided into meiosis I and meiosis II. The process completes in eight stages.
After the process of cytokinesis, the daughter cells become haploid and have their chromosome paired up.
Thus, Meiosis I, the first step of meiosis after cytokinesis, is when the daughter cells initially become haploid.

Which gas is responsible for global warming and Which gas is responsible for ozone layer depletion?
Answer:
Green house gases like carbon dioxide, carbon monoxide, carbon tetra chloride, methane, sulphur dioxide, nitrogen dioxide, etc .. are responsible for Global warming and Chlorofluorocarbons and nitrides of oxygen are responsible for Ozone layer depletion.
Explanation:
One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).

How would the absence of juxtamedullary nephrons affect the volume of urine and its osmotic concentration?
Answer:
Increase volume; decrease osmotic concentration
Explanation:
Nephron is the functional unit of a kidney.
The juxtamedullary nephrons is responsible for the development of the osmotic gradients. The osmotic gradient helps in ensuring the urine is well concentrated and helps in adequate water reabsorption.
The absence of juxtamedullary nephrons affect the volume of urine and its osmotic concentration by Increasing the volume and decreasing the osmotic concentration.

Which question could violate laws aimed at achieving equal employment opportunities?
A. What is your address?
B.what are your job skills?
C.what is your job history?
D. What is your religion?
Answer:
D. What is your religion?
Explanation:
I believe the answer would be D because this is the only question out of the options that could cause bias from the employer. Let's compare this to the other options.
For option A, knowing your address could be crucial information for the employer/company, and shouldn't cause bias or a reason for the employer to not agree.
For option B, knowing your job skills is also crucial information for the employer to know if you are fit for the job.
For option C, knowing your job history is similar to option B...the employer may need to know this information to know if you are fit for the job/if you have experience in this area of work.
Lastly for option D, knowing your religion should not be crucial information for an employer. This would violate laws aimed at achieving equal employment opportunities because this leaves room for the employer to use bias based on his/her religion.

Identify the independent and dependent variables Mindy and her lab group are given 2 aloe vera plants as test subjects and are asked to create a testable hypothesis of their choice and design a scientific experiment to test that hypothesis. Mindy’s hypothesis is as follows: “If aloe vera plants receive no sunlight then they will die.” Mindy designs an experiment where she will take both plants and put them in a window next to one another and plant them in the same size pot with the same kind of soil and they will receive the same amount of water at the same times over the course of a month. One plant however will be kept in the sunlight while the other will have a box placed over it to prevent it from receiving any light
Answer:
Independent variable: Amount of sunlight
Dependent variable: Plant height
Explanation:
The independent variable is the one that a scientist intenionally changes in an experiment, while the dependent variable is the one that changes in response to the independent variable. In this case, the amount of sunlight given to each plant is intentionally varied so it is the independent variable, while the height of each plant depends on the amount of sunlight given so it is the dependent variable.

For the following biomolecular interactions, choose the main weak force interactions that mediates them.
Interaction between hydrophobic (nonpolar) amino acid side chains van der Waals interaction
Repulsion between negatively charged backbone of DNA double helix van der Waals interaction
Interaction between water and carbonyl oxygen of guanine hydrogen bond
Answer:
Interaction between hydrophobic (nonpolar) amino acid side chains is due to hydrophobic interactions.
Repulsion between negatively charged backbone of DNA double helix is due to electrostatic repulsion forces.
Interaction between water and carbonyl oxygen of guanine is due hydrogen bonding
Explanation:
The hydrophobic effect refers to the tendency of non-polar substances forms aggregates in an aqueous solutions in order to avoid interactions with water molecules. This results in a favorable entropy increase.
For non-polar amino acids, hydrophobic interactions are important in stabilizing their structure wherein they are densely packed within the core of a protein while those with with polar groups are found in the exterior.
The phosphate backbone of DNA is negatively charged. Since like charges repel, therefore, electrostatic repulsion forces of the ions are responsible the repulsion of the backbone DNA double helix.
Hydrogen bonds are formed between electronegative oxygen atoms and hydrogen atoms of neighboring molecules due to the partial negative and positive charges on each of the atoms.
This hydrogen bonding is responsible for the interaction between water and carbonyl oxygen of guanine as the hydrogen atoms of the water molecules are attracted to the oxygen atoms of the guanine molecules due to the partial charges on each of the atoms.
