Thomas A. Edison, famous for his invention of the light bulb, once said “I have not failed. I’ve just found 10,000 ways that won’t work.” What does this mean to you? Why is this a good way to describe science
Answer:
Because he has tried many other forms and become a master on the subject therefore from a business standpoint he could corner the production. But from a moral standpoint he has overcome a great challenge that will influence generations to come. It is a good way to describe science because it shows that to overcome a great challenge requires great patientice and time and trial and error.

8. Two plants are grown using the same light and pots. One plant is given water that has been microwaved and the other plant is given regular tap water. Their height is measured after 2 weeks. independent and dependent variable
Answer:
Independent variable: water given to the plantsDependent variable: height of each plantExplanation:
The independent and the dependent variables are the two principal factors needed in an experiment.
• Manipulated variable: Refers to all the variables in an experiment that provoke a response in another variable. They are also known as independent variables. The independent variable changes or is controlled and modified in the experiment to analyze how the other variable responds to it. The researcher can change it to see what changes it implies in an object, process, trait, or anything that depends on them, to study its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the researcher manipulates the water given to the plants. One plant receives water that has been microwaved and the other plant receives regular tap water.
• Responding variable: Refers to the dependant variable. The dependent variable is the one that is being investigated, studied, and measured. It represents a quantity of something which value depends on how the independent variable is modified. A 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, the dependent variable is the height of each plant after 2 weeks of treatment.
• Controlled variable: Refers to those variables in an experiment that are controlled and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example these are the light and pots.
Answer:
water given to the plants
height of each plant

Pasteur disproved spontaneous generation by demonstrating that microorganisms did not grow in broth that was heated in swan-neck flasks and then allowed to sit undisturbed for several days. It was important that he placed the broth in control and experimental flasks before heating rather than transferring the broth to new flasks after heating. Why?
Answer:
See the answer below
Explanation:
It was important for Pasteur to place the broth in the flasks before heating rather than transferring it to new flasks after heating because the new flasks might be a source of contaminants in the form of microorganisms, hence, leading to a biased outcome.
In order to prevent cross-contamination and preserve the integrity of the outcome of the experiment, the broth needed to be placed in the flasks before heating instead of transferring it after heating.

What would Iraq have to do in order to reach a zero growth rate? What kinds of challenges might the Iraqi government face in trying to implement these measures?
Answer:
Iraq will have to massively reduce the birth rate to achieve a zero growth rate. In the middle east, there is more sexual freedom which may cause sexual education to be useless. Iraqi government would most likely have to give widespread contraception to its citizens.They would either have to lower birth rates or increase death rates. It would be more practical for the Iraqi government to provide contraception's and sexual education among its citizens to decrease birth rates.

Reducing gene flow causes speciation because the species are not allowed to exchange genetic material.
How does reducing gene flow cause speciation?When gene flow is blocked from exchanging between populations, this results in speciation that prevents the populations of the same species to exchange genetic material.
So we can conclude that reducing gene flow causes speciation because the species are not allowed to exchange genetic material.

Fiddler crabs are invertebrates. That means they do not have a backbone (that's made out of vertebrae). Does this mean they don't have a skeleton?
Answer:
they do have skeleton which is called exoskeleton, main component is chitin
Fiddler crabs don't have a skeleton. Instead, they occupy a carapace, a rectangular shell. As they expand, the carapace is absorbed, and a new, larger one is produced.
What are invertebrates?
The paraphyletic group of animals known as invertebrates lacks the notochord-derived vertebral column and does not even develop one. Except for the chordate subphylum, all animals fall within this classification.
To assist remove food from sand, they frequently dine in a watery puddle. Because both of a female's claws are little, she has an advantage over a male in terms of finding and consuming food. Feeding is more challenging for older males due of their main claw.
Therefore, fiddler crabs don't have a skeleton.

HELP ME ASAP HELP ME PLZZZ HELP MEEEEEEEEE
Answer:
Precise, but not accurate
Explanation:
First, let's define precision and accuracy.
Precision: how close multiple measurements are
Accuracy: how close the measurements are to the true measurement
The three measurements are:
167.0 g, 166.9 g, 167.2 g
The true mass is 172 grams.
We can see that each measurement is far from the actual value of 172 grams: about 5 grams off. They are not close to the actual measurement, so they are not accurate.
The three measurements are very close to each other. They are all within 0.3 grams of each other. The measurements are all close to each other, therefore they are precise.
Therefore, the measurements are precise, but not accurate.
Answer:
More precise than accurate.
Explanation:
Precision is a measurement of how close your measurements to each other, accuracy is a measurement of how close your measurements are to the true value.
Question 2 of 10 which structure is most likely used for motion?
Answer:
It's the picture of the dolphins tale or fin, whatever it's called.
In this case answer B.
Explanation:
The leaf isn't used for motion.
The tail is moved up and down etc.. and creates motion that helps the dolphin swim.
The apple isn't used for motion.
The wolf's eye is used for sight, not motion.
Thus the answer is picture B.
The structure that is most likely used for motion is the tail fin of the fish. The correct option is B.
What is motion?Motion is changing or modifying an object when applying a force. The living body move or locomote with the locomotion organ. These are different types of locomotion organs in different organs.
There are different organs in different animals for locomotion and motion. In humans there are legs, in animals there are paws and in fishes, there are fins, in insects, there are wings and legs.
There is no movement made by the leaf. The dolphin swims with the assistance of its tail, which is moved up and down and in other directions. It is not used to move the apple. The wolf's eye is for sight alone, not for movement.
Thus, the correct option is B. the tail fin of the fish.

Which of the following is NOT a true statement regarding macromolecules
The correct option associated with the question is given as follows:
a.All macromolecules are monomers.
b.All macromolecules are polymers made up of smaller units.
c.All macromolecules are created by dehydration reactions.
d.All macromolecules contain carbon.
Answer:
The correct answer is: a. All macromolecules are monomers.
Explanation:
Macromolecules are huge biological molecules made out of thousands of covalently associated atoms. Carbohydrates, lipids, proteins, and nucleic acids are altogether macromolecules. Macromolecules are framed by numerous monomers connecting together, shaping a polymer.
In doing such, monomers discharge water atoms as side products. This kind of reaction is called dehydration reaction, which signifies "to assemble while losing water."
lipids are worked from an alternate arrangement of monomers that look like each other in creation and size. Lipids are not polymers, since they are not made up of monomers.

How does a virus get into the cell?
Answer:
A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host—and the cells within the host—that can be infected by a particular virus.
Answer:
Viruses initially stick to cell membranes through interactions unrelated to fusion proteins. The virus surfs along the fluid surface of the cell and eventually the viral fusion proteins bind to receptor molecules on the cell membrane (4). If only binding occurred, the two membranes would remain distinct.

Explanation:
If after studying a population for a trait determined by a single pair of alleles you fi nd that the population is not in equilibrium, what possible reasons might explain the lack of equilibrium
Answer and Explanation:
The criteria for maintaining a Hardy-Weinberg equilibrium are:
Random matings: mating probabilities between individuals with determined genotypes depends on the products of frequencies of those genotypes. No superposed generations: each individual can leave their gametes in the pool only once. No mutations: There is no incorporation into the genetic pool of new gametes originated by mutation of preexistent alleles. No migration: There is no incorporation of gametes originated in another population. Infinite population size: the probabilities of randomly taking an A gamete from the pool are p and the probabilities of taking a B gamete from the pool are q. No natural selection: Each individual has the same surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.If one of these points does not carry out, then the population under study is not in equilibrium.
If endogamy or exogamy occurs affecting random mating, If genetic drift is going on, the population is not infinite-sized and there are no random matings,If there exist genetic flux, which means that the population is not closed and migration occurs, If natural selection is acting over the population, If there occur mutations,Then the observed allelic and genotypic frequencies are different from the expected ones if the population under study was in H-W equilibrium.

This type of biomolecule is responsible for numerous cellular functions including increasing reactions, providing structure for healing, antibodies to fight infection and aiding in transport of substances and sending signals to cells. What is the name of this biomolecule?
Answer:
Proteins
Explanation:
Biomolecules are any organic molecule, meaning they contain carbon and they are produced by cells in living organisms, and they generally aid in the functioning of that living cell. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.
Proteins are large biomolecules, as they are also macromolecules.
Proteins are responsible for cellular functions and regulation of the body's tissues and organs.
When we talk about providing structure for healing, then proteins fit perfectly as collagen works on quick healing while immunoglobulin is an example of a protein that fights of harmful organisms.
Ferritin, Hemoglobin is an example of a protein that transports essential molecules from one part of the body to a target organ or destination.
Insulin for example is a protein that sends signals to target organs and is considered very important.
