What is Theory ?

A principle formed to explain things, certain phenomena, or fact which was validated previously known as Theory.

It can be speculation of any assumption which need to be proved.

Further more an ideal theory must be an authoritative principle, which is a result of continuous observation, proper examination, analysis logically  accurate explanation of a specific phenomenon.

The characteristics for ideal theory are,  it must possess the quality and authenticity.

A wide acceptance by people and the quality should be evaluated correctly.

It must solve the problems potentially and expert verified, confirmed hypothesis.

It must have the ability to analyze the past events, have some descriptive approach for a particular topic.

Xavier filled up a balloon to its maximum capacity inside his air conditioned home.

He walked outside to the intense summer heat. According to Charles' Law, the balloon will pop up.

What is Charles' Law ?

Charles's law or a gas law which states that gases will expand when heated.

The law is called as the law of volumes which was discovered by French scientist Jacques Charles, who formulated it in the 1780s.

Charles's Law is an ideal gas law as it id defined in an ideal condition such as at constant pressure, the volume of an ideal gas is directly proportional to absolute temperature.

The law can be represented as V/T = k, where "V" refers to volume and "T" refers to temperature.

An example is during winters when you take a basketball outside, the ball shrinks, this is because of lower temperature. Similarly it is  important to check the tyre pressure in the car during cold days.

why would some people consider genetic engineering of cisgenic crops more natural than genetic engineering of transgenic crops

Its the stoopid for mee

Answers

Answer:

Public perception has proven to be essential for the approval of genetically modified crops, in particular in Europe. Several surveys and focus group interviews in the United States and Europe clearly show that both intragenic and cisgenic crops are acceptable to a greater number of people than transgenic crops. Some people believe that cisgenesis should not face as much regulatory oversight as genetic modification created through transgenesis as it is possible, if not practical, to transfer alleles among closely related species even by traditional crossing. So, there is a need to use genetic techniques to improve crops over recent decades. Through the use of transgenics, one can produce plants with desired traits and even increased yields. The transgenics would allow for more crops that last longer and withstand pests and diseases.

Explanation:

A farmer made a pesticide (a chemical that keeps insects away) from the leaves of the plant and sprayed it on his crops. The first year it is extremely effective and the farm loses only 1% of its crop to insects. Make a prediction as to the effectiveness of the pesticide in 5 years, be sure to give evidence to support your claim.

Answers

Answer:

See the answer below

Explanation:

In 5 years, the effectiveness of the pesticide would have reduced because the forces of natural selection would continue to act on the population of the insects and ensures that only those that are fit survive and contribute more to the subsequent generations.

Each year the pesticide is administered, those that are not able to adapt to its effects die off, leaving those that posses the pesticide-resistant genes to survive, reproduce, and give birth to offspring that would have inherited the survival gene and become resistant to the pesticide themselves.

Hence, in 5 years, more of the population of the insect would survive the effects of the pesticide leading to a reduction in its effectiveness. The population of the insect is said to have evolved by natural slection according to Darwin.

A population is composed of bacteria that are very sensitive to light. They live in a lake that is in a cave so they flourish. Slowly, however, a hole begins to erode in the cave's roof. As the days pass, light begins to fliter in and the cave starts to be dimly lit. The bacteria begin to die. While the erosion is taking place, however two individual bacteria in the soil above ground fall into the lake. These bacteria cannot survive in the dimness of the poorly-lit cave, so they die immediately. Days later, the hole has opened up so that light floods the cavern. Nevertheless, the bacteria that were once dying are flourishing, with a population larger than they had before the erosion. Explain how this could have happend.

Homeostasis in the human body is often maintained by a: A. Positive feedback loop B. Negative feedback loop C. Neutral feedback loop

Answers

Answer:

B. Negative feedback loop

Explanation:

A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

Homeostasis in the human body is often maintained by a Negative feedback loop. So, the correct option is B.

What is Homeostasis?

Homeostasis is defined as a state of stable internal, physical, and chemical conditions maintained by living systems that are optimal functioning conditions for the organism and includes many variables like as body temperature and fluid balance, some being kept within pre-determined limits.

Homeostasis is usually maintained by a negative feedback loop involving the stimulus, the sensor, the control center, and the effector. Negative feedback serves to reduce an excessive response and keep a variable within the normal range where it regulates body temperature and blood sugar levels.

Thus, Homeostasis in the human body is often maintained by a Negative feedback loop. So, the correct option is B.

B. Analyze data that was truly observed, and not data that was expected or desired.
C. Publish experimental results only if they agree with current theories or public opinion.
D. Continue the procedure of an experiment or investigation under all circumstances.

Answers

Answer:

B. Analyze data that was truly observed, and not data that was expected or desired.

Explanation:

In the scientific method, scientists or researchers are expected to make fair assessments and analysis of data. This prevents, what we call bias. When making conclusions, scientists need to analyze the data as they are and what was observed even if it does not agree or come out the way they expected it. If one will manipulate the results just to justify their own reasoning, the results cannot be regarded as facts.

Analyze data that was truly observed, and not data that was expected or desired, examples under ethical standards. Thus option B is correct.

What is scientific method ?

scientific method is a structured form of study where a group of facts can be explained by using scientific hypothesis and laws.

Every scientific theory determined on the basis of scientific method, where scientist make an observation and formulate a hypothesis.

After this design an experiment and conduct the experiment to test that hypothesis.

If the result of hypothesis is incorrect, then new hypothesis will be developed and begin the the experiment again.

If the result of  hypothesis is correct and supported by the results of the experiment, test again to get the accuracy of the result.

In scientific method, scientists make fair assessments and analysis of data and it prevents bias.

Thus option B is correct.

Answers

Answer:

False

Explanation:

Bacterial flagella have a biological motor that spins within the cell wall and is NOT powered by ATP.

Instead the Bacterial flagella is known as the biological motor that spins the flagella for the motion of the bacteria and is as a result of the electron imbalance in the membranes which helps in the generation of a gradient. The cells makes use of the energy present in the gradient through the help of proton motive force which helps to propel it.
