do water molecules tend to push away from each other
Answer:
no the molecules tend not to push away from each other
Answer: No/False
Explanation: Water molecules stick together because of cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be less or more cohesive. Hydrogen bonds cause water to be more attracted to each other, therefore making them stick together.

This question is asking to identify the directional relationship between the following organs. They are explained below.
Explanation:
1. The heart is MEDIAL to the lungs because it is located towards the middle in relation to the right and left lungs.
2. The knee is DISTAL to the hip because it is farther away from the point of attachment of the hip joint.
3. The wrist is PROXIMAL to the hand because the wrist is closest to the point of origin of the hand.
4. The mouth is INFERIOR to the nose because it is lower in direction to the nose.
5. The thorax is SUPERIOR to the abdomen because it is located above the abdomen.
6. The thumb is DISTAL to the ring finger because it is far away from the ring finger.
7. The sternum is ANTERIOR to the heart because it lies in front of the heart
8. The skull is SUPERFICIAL to the scalp because it is close to the body surface.
9. The ears are LATERAL to the nose because it is towards the middle line of the nose
10. Dorsal refers to the BACK of the human body, while ventral refers to the FRONT of the human body.
The heart is medial to the lungs. 1- medial, 2- distal, 3- proximal, 4- Inferior, 5- superior, 6- distal, 7- anterior, 8- superficial, 9- lateral, 10- back, and 11- front.
In the thoracic cavity, the heart is located in the middle of two lungs and before a vertebral column. However, it is located behind the breastbone plate, i.e. the sternum.
The thorax, also known as the chest, is the upper part of the trunk between the neck and the abdomen. The thorax is made up of several parts: the thoracic wall and several cavities.
The sternum is a bone located in the anterior middle line of the thoracic region of the body. It forms the base of the rib cage. The sternum is the anterior-most part of the body.
The sternum protects the thoracic tissues from injury. It also serves as the bony attachment point for various muscles.

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.

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.

After learning about Addie, think about infections that you or family members had. Have you or a family member ever taken antibiotics for an infection/skin infection/rash/ear infection/chest cold? What happened?
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.

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

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.
At what part of the growing process is creativity more important? When is consistency more important?
Answer:
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.
Suzie Q wants to know how different colors of light effect the growth of plants. She
believes that plants can survive the best in white light. She buys 5 ferns of the same
species, which are all approximately the same age and height. She places one in
white light, one in blue light, one in green light, one in red light and one in the
closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a
day for 2 weeks. After the two weeks, Suzie observes the plants and measurements.
4. What measurements could Suzy make to determine how different colors of light
affect the growth of plants?
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.

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.

Enzymes are proteins that have a three-dimensional shape that is specific to a particular substrate. Environmental conditions can change the shape of the protein. What is the most likely result if the shape of the enzyme changes?
Answer:
The enzyme will no longer be able to catalyze the reaction with the substrate.
Explanation:
The enzyme will no longer be able to catalyze the reaction with the substrate if the shape of enzyme changes. The correct option is B.
What is enzyme-substrate reaction?A substrate needs to enter the enzyme's active site. This results in the formation of the enzyme-substrate complex.
The reaction then accomplished, transforming the substrate into products and forming an enzyme products complex. The products after which end up leaving the enzyme's active site.
When an enzyme is bonded to its substrate, an enzyme-substrate complex is formed.
Enzymes encourage chemical reactions by bringing substrates together in the best possible orientation, thereby providing an ideal chemical environment for the reaction to take place.
Enzymes change their shape in order to bind to their substrates. The process by which enzymes change shape is known as induced fit.
Since enzymes in the given scenario is changing their conformation, it will lead to non binding of the substrate.
Thus, the correct option is B.
