What kind of effect would occur to the biotic factors if the water became contaminated by fertilizer (abiotic factor)?
If the water becomes contaminated by fertilizers, the biotic factors will not be survived properly in that water. Due to contamination, genetic changes and diseases can cause.
What are biotic factors?Biotic factors are those factors that are living or once living. The characteristics of biotic factors are growing and reproducing. These factors are plants, animals, fungi, bacteria, etc.
Fertilizers are chemicals that are used in plants and farming to increase the growth of crops and plants. These fertilizers, in the end, go into water bodies and contaminates them.
These fertilizers are not good for water, as animals drink this water and due to heavy chemicals, these fertilizers cause deformities in animals and plants.
Thus, The biotic factors in the water will not be able to survive effectively if it becomes tainted by fertilizers. Diseases and genetic alterations may result from pollution.

Cells are the basic unit of structure and function of all living things. All cells come from other cells. Cells are generated from nonliving materials.
Answer: Hi!
If a skin cell divides into a new skin cell, this best demonstrates the component of cell theory that all cells come from other cells. The process that this cell is going through is called mitosis, where one cell splits into two. This can occur with skin cells, toe cells, lung cells, etc. - any body cells besides reproductive cells.

Explain why the average temperature on Earth would be 0 degrees Fahrenheit
Without the layer of greenhouse gases.
Answer:
The average temperature on Earth would be 0 degrees Fahrenheit because there would be nothing holding in the heat inside the atmosphere.
Explanation:
The Greenhouse effect happens when the heat from Earth gets trapped in the atmosphere, making the Earth warmer. Without the Greenhouse gasses, the heat escapes the atmosphere, leaving Earth to being colder.

Different rose bushes are grown in a greenhouse for two months. The number of flowers on each bush is counted at the end of an experiment.
IV____________________________________________________
DV____________________________________________________________________
Constant _____________________________________________________________________
Independent Variable - The type of rose bush.
The independent variable is something you change. In a good experiment, you should only have one independent variable so things don't get confusing. In this experiment, the type of rose bush would be the independent variable. It is the one thing that is being changed.
Dependent Variable - The number of flowers.
The dependent variable is the data that is obtained in an experiment. In this experiment, the number of flowers would be the dependent variable. The amount of flowers is the data from the experiment.
Constant Variable - Soil, light, water, greenhouse, amount of time.
The constant variable is something in the experiment that stays constant and doesn't change. In this experiment, it mentioned having the timespan of two months and being in the same greenhouse, those are constants. Some other things that aren't mentioned but would be constants are the type of soil, color and amount of light, amount of water, etc.

Does an electric motor turn faster if you increase the voltage? Voltage of the electricity used is measured in volts. Speed of rotation measured in revolutions per minute (RPMs)
Answer:
Yes.
Explanation:
Yes, an electric motor move faster if we increase the voltage because by increasing voltage we supply more energy in the form of current. Voltage means energy available per unit charge so if the voltage increases more energy is available for an electric motor in the form of electric current and by using more energy they move with high speed. The unit of Voltage is volts.
A well designed experiment can only have one dependent variable?
True
False
A well-set-up experiment is defined and concluded by the presence of the variables. There may be more than one or two dependent variables in an experiment. Thus, the statement is false.
What is the dependent variable?Dependent variables are defined as values that are not independent of the factors rather than the conditional value that gets altered by the conditions of the experimental design. These values are supposed to be in accordance with the law and hypothesis.
An experimental design can have more than one dependent variable as it allows the hypothesis to have a precise and accurate solution to the problems that also can respond to various queries.
Therefore, the statement is false.

Your question has been heard loud and clear.
Well by the nature of science itself , we know that it is a rapidly progressing area . So , scientific laws are basically ideas from theories , it does not mean that it is absolute , because future research of that same topic on which the law is based , can always change and thus the theory and thus the law. So , scientific laws and theories change over time due to new phenomena and scientifc research that gives a more accurate theory than the old laws and theories.

The mass is the same. After the reaction, the

Answer:
The mass increases. After the reaction, the solution and gas have more mass than the baking soda and vinegar (B)
Explanation:
The mass increases. After the reaction, the solution and gas have more mass than the baking soda and vinegar (B).
What happens to the full mass of the chemical substances on the give up of chemical reaction?In a chemical response, the overall mass of all the materials taking elements inside the reaction stays identical. also, the quantity of atoms in response remains identical. Mass can not be created or destroyed in a chemical response.
How will the mass of the system alternate as the reaction proceeds?If a chemical reaction is finished in a closed gadget (when nothing greater can get in and nothing can escape), then the mass will stay steady. but, if the chemical reaction occurs in an open device (where air can get inside and outside), then mass might also seem to trade.

DNA consists of two strands with complementary pairs of nucleotides. Match each strand of DNA with its complement. Tiles

The matching of each strand of DNA with its complement is as follows:
CATGGAT: GTACCTA.CGGTACA: GCCATGT.CGGTTAA: GCCAATT.TAAGGCC: ATTCCGG.ATTGCGT: TAACGCA.What is DNA complementarity?
DNA complementarity may be defined as the process through which demonstrates the resemblance of DNA bases in the double helix such that adenine in one strand is opposite thymine in the other strand and cytosine in one strand is opposite guanine in the other.
The mechanism of DNA complementarity also explains the principle of Chargaff's rule. It states that the amount of adenine equals to the amount of thymine while the amount of cytosine equals to the amount of guanine.
According to Watson and Crick, DNA consists of two strands with complementary pairs of nucleotides. One strand is a template to the synthesizing strand which forms complementarily with respect to the template or parental strand.
Therefore, the matching of each strand of DNA with its complement is well described above.
