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.

Answer:

Suzie can measure the HEIGHTS of the plants in metres (m) or centimeters (cm)

Explanation:

According to this question, Suzie Q wants to know how different colors of light effect the growth of plants. She sets up the experiment by exposing 5 ferns of the same species to different colors of light (white, blue, green, red).

After ensuring that some variables called constants like same 20 mL of water, same fertilizer (miracle-grow) etc are the same for all ferns, She then measures the growth of each fern placed under different colors of light.

The independent variable in this experiment is the different colors of light while the dependent variable is the growth of the plants. This question is asking for how Suzie could measure the dependent variable (growth). Suzie can measure the growth of the ferns placed under different colors of light by RECORDING THE HEIGHTS OF EACH FERN IN cm or m.

The green house effect is a natural process that warms the Earth surface.

Creativity is most important . It develop in every stage of life. I t could be consistent when it get stable.

Explanation:

We could not count consistency as everything but it is counted for a lot. Creativity is more important at every stage when you grow up . The creative mind play role as a machinery. Consistent means you are not doing anything, you are constant.

As we can say that process is more important. When you are consistently working you are learning something new. So that when you are thinking about something too much then you wont do it. Creativity is rooted in the culture of an individual. Creativity is bounded with culture. It consists the dynamic thought. Creativity can no any exception.

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.

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

Answer:

The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends.

The statement most accurately describes bacterial cells is bacterial cells have DNA, but they do not have a nucleus. The correct option is D.

Bacterial cells are prokaryotic cells and the most primitive cells. They are most simpler cells, and contain no true cell organs and a nucleus. The cell is covered with a cell membrane and a tail-like structure called flagella is present.

The bacteria are microorganisms, so they are very tiny. They are single-celled and DNA is present in these organisms but in a circular form coiled inside the cell.

Thus, the correct option is D. bacterial cells have DNA, but they do not have a nucleus.

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.

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.

Answer:

Yes, I have taken antibiotics for an infection or infectious disease.

Antibiotics are specialized drugs to generate bacteriostatic or bactericidal effects in BACTERIA.

These, like all drugs, have adverse effects that may be worse or less serious according to the potency of the drug.

Each antibiotic has different spectra of bacteria, that is, they can affect more or less bacterial species.

Explanation:

That antibiotics are bacteriostatic implies that they stop bacterial metabolism, and that they are bactericidal indicate that they eliminate or kill the bacteria, each antibiotic is special for each bacterium.

In infectious diseases or infections it is important to know what bacteria we are facing, doing a culture to detect the species and also an antibiogram that warns us to which antibiotic this bacteria is resistant, if it is.

In this way, antibiotic therapy will be effective since the bacteria will be within the spectrum of the chosen drug and will not present resistance, these diagnostic methods are necessary because there are bacteria with beta-lactamases as a resistance factor, that is, resistant to beta lactams, it is for That is why an inhibitor of these enzymes was launched so that these bacteria cannot destroy the drug and have efficacy at the end of the day, this beta-tetramase inhibitor is clavulanic acid, which together with penicillin were the great discovery of pharmacology.

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.

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.

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.
