The type of neuron that can detects a raindrop falling on skin is sensory neuron. The correct option is D.
What is a neuron?The basic building blocks of the brain and nervous system are neurons (also known as neurons or nerve cells).
Neurons are the cells that receive sensory information from the outside environment and are in charge of providing motor instructions to our muscles.
The glial cells and the neurons are the two main subtypes of brain cells. While neurons in the brain play the dominant role, glial cells predominate in certain regions of the brain.
When you contact a hot surface with your fingertips, your sensory neurons will fire and transmit messages to the rest of your nervous system about the information they have just received.
Sensory neurons are the nerve cells that are activated by sensory input from the environment.
Thus, the correct option is D.

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.
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.
Neurotransmitter release is an example of(1 point) cyclical behavior. autocrine signaling. paracrine signaling. cellular miscommunication.
Answer:
Neurotransmitter release is an example of paracrine signaling.
It is the release of chemical ligands called neurotransmitters by the presynaptic cell (the cell emitting the signal).
Hope it helps.
An example of ( Neurotransmitter release ) is ; Paracrine signalling ( C )
Neurotransmitter release is stimulated by the presence of nerve impulse arriving in the presynaptic terminal of the nervous system. the released neurotransmitter finds its way into the synaptic gap before binding receptors present at the postsynaptic terminal ( membrane ).
while the release of the neurotransmitter occurs at the active zones of the presynaptic terminal.An example of the these releases includes the paracrine signalling , Dopamine, Glutamate.
Hence we can conclude that an example of Neurotransmitter release is Paracrine signalling.

Bacterial flagella have a biological motor that spins within the cell wall and is powered by ATP. This allows the flagella to spin in a whiplike motion to propel the bacterium. Is this statement True or False?
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.
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, what will likely happen to his balloon?
Answer:
it will pop
you can look up more on it to make sure I'm correct but that's what I got from this
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.

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

Which part of a phospholipid is hydrophilic
Answer:
nonpolar fatty acid tails
The hydrophobic, or “water-fearing,” part of a phospholipid consists of its long, nonpolar fatty acid tails. The fatty acid tails can easily interact with other nonpolar molecules, but they interact poorly with water.
Answer:
The head
Explanation:
You know how phospholipids always look like they're facing outward? Well, it's because they have hydrophilic (water-loving) heads and hydrophobic (water-fearing) tails. The tails are on the inside of the phospholipid bilayer because they are hydrophobic. The heads, on the other hand, are hydrophilic, meaning that they face the outside of the phospholipid bilayer, towards the water.

Imagine you have an objective lens that magnifies 100 times your image. If your eye piece magnification is 10x. How much will the total magnification be..? Explain your answer.
Answer:
1000x
Explanation:
Magnification is process of enlarging the appearance of an object (that is making the object look bigger than it is). The magnification of an object is usually described using a number.
The total magnification is the product of the objective lens power and the eyepiece magnification.
Total magnification = objective lens power × eyepiece magnification
Total magnification = 100x × 10x = 1000x

Society expects scientists to follow ethical practices and meet many ethical standards. Which is an example of one of these ethical standards?
A. Investigate only the events that affect people's lives or livelihoods.
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.
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.

Explanation:
why would some people consider genetic engineering of cisgenic crops more natural than genetic engineering of transgenic crops
Its the stoopid for mee
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.

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. There are 2 successive things that must have happened to cause this. What were they.
