Answer:
Energy is the ability to do work. Work refers to any change in the position, shape or size of an object as a result of its contact with another object - like dropping a rock on your foot. The amount of energy that is exchanged between two objects when they come into contact is called mechanical energy. This type of energy transfers all kinds and forces from one part of an object to another and can be transferred in many directions at once (for example, heat). Work and potential energy are related but not identical topics. Potential energy includes work done by gravity pulling things down and using elastic forces squeezing something together like a spring.
Explanation:
Answer:
Energy exists in many forms, but we can group them into three general categories: kinetic energy, potential energy and thermal energy. Work is the transfer of quantities of one form of energy to another (i.e., from a muscle to its surroundings), or vice versa. Kinetic and potential energies are classically called "energy" because they are not dependent on a particular point in space for their existence; indeed, all physical systems contain both kinetic and potential energies.
The tendency to apply force and a change in distance to an object is work, on the other hand, energy is the tendency to create or supply work.
• Energy is the outcome of the work performed, while work is the tendency to supply force and a change in distance to an object.
• Energy is illustrated as the property of a system, while work is an action, which is done on the thing that leads to displacement.
• Energy is the outcome of the work done, while work is the activity performed on the thing, which results in certain kind of displacement.
Thus, there is a significant difference between energy and work.

Which of the following mechanisms of change in genefrequencies is responsible for the antibiotic resistance of E. coli in this experiment?
A. founder effect
B. natural selection
C. population bottleneck
D. genetic drift
Natural selection is the mechanism responsible for the antibiotic resistance of E. coli.
Natural selection is a mechanism that favors the adaptation of organisms to survive in their environment, thrive and reproduce.
In the context of antibiotic resistance, antimicrobial substances exert selective pressure on microbes that encourages the evolution of resistance.
Those capable of resisting the effects of antibiotics survive and reproduce, while the vulnerable either die or have their growth inhibited.
The excessive and inappropriate use of antibiotics favors selection for antibiotic resistance in bacteria.
E. coli is characterized by having Gram negative bacilli, it represents the greatest risks of zoonotic transfer of resistance.
In general, and when a treatment is short, there is an elimination of sensitive saprophytic strains of E. Coli and an enormous predominance of resistant strains.
Bacteria also acquire antimicrobial resistance through vertical or horizontal transfer of genetic information.
Therefore, we can conclude that resistance to antibiotics in E. coli is due to the process of natural selection since it evolves to resist the action of an antimicrobial agent.

Stage 1 sleep is characterized by a predominance of ________ wave activity in the brain.
Answer: theta
Explanation:
Stage 1 sleep is characterized by a predominance of alpha and theta wave activity in the brain.
The stage of entering the state of sleep is also called stage 1 and is considered as a boundary between the waking state and sleeping.
In this stage, the rhythm alpha predominates, which tends to slow down and show the presence of waves called theta, which are of greater amplitude.
Alpha activity is a pattern that results from a person resting and relaxing.
Theta waves are broad, low-frequency waves that would indicate a state of extreme relaxation and drowsiness.
Eye movements at this stage are slow and muscle tone drops. Phase I is short-lived and occupies about 3-5% of sleep.
Therefore, we can conclude that in stage 1 of sleep the alpha waves would be combined, with a new activity, called theta.

Nitrogen-fixing bacteria are prokaryotic organisms that transform nitrogen gas into nitrogen compounds like ammonia and nitrates.
The graph that correctly shows the nitrogen-fixing bacteria in the soil is graph 2.
Nitrogen-fixing bacteria can be explained as:
Nitrogen-fixing bacteria are the organisms that fix the atmospheric nitrogen into the compounds of nitrogen as ammonia and nitrates.The conversion of the atmospheric nitrogen is done in two steps, the first step involves the conversion of atmospheric nitrogen to ammonia. The second step involves the conversion of ammonium to usable nitrate. Graph 2 represents the amount of atmospheric nitrogen decreasing with an increase in the amount of ammonia. It indicates that atmospheric nitrogen is utilized and converted into nitrogen compounds.
Thus, the correct answer is graph 2.

Ashley hypothesizes that adding coffee grounds to the soil will help the plants grow faster. She designs a controlled experiment to determine if this hypothesis is supported.She grows one group of soybean seedlings under normal conditions. She mixes three tablespoons of coffee grounds into the soil of the second group and grows the seedlings under the same light, temperature, and watering regimen. After three weeks, she measures the height of the seedlings and compares the two groups.Identify the parts of the experiment. Place only one term in each category. You will not place all the terms.
The purpose of this study is to determine the experimental group, the control group, the dependent variable, and the independent variable.
Designing and carrying out an experiment is the best approach to prove whether a hypothesis is true or incorrect. To ensure that an experiment examines exactly what the hypothesis claims, scientists must be cautious in how they construct it.
To ensure that only one factor is being altered in an experiment, the independent variables are therefore divided into two groups.
The control groupThe experimental groupThe control group does not experience any changing variable.
The experimental group receives all of the experiment's circumstances, changes as well as the one variable that the experiment is testing.
In Ashley's experiment:
The experimental group:
Seedlings grown with coffee grounds.The control group:
Seedlings grown without coffee grounds.The dependent variable:
Seedling heightThe independent variable:

Explanation:
Semi-conductive describes a component which conducts electricity less well than a good conductor but better than an insulator.
The hose should be semi-conductive, with a resistance high enough to insulate a stray current but conductive enough to get rid of static charge build-up.
Carbon black can be used to lower the resistivity of plastics, imparting antistatic, semi-conductive, or conductive properties.

Due to the partial charges on atoms in a water molecule, ____ in water molecules are attracted to oxygen atoms in other water molecules.
Hydrogen bond in water molecules are attracted to oxygen atoms in other water molecules.
A hydrogen bond is a strong dipole-dipole attraction which occurs between:
the hydrogen atom attached to a strongly electronegative atom (for example oxygen in water molecules)another strongly electronegative atom with a lone pair of electronsHydrogen bonding occurs in the following compounds which include water, hydrogen fluoride and ammonia.
When an electronegative atom such as oxygen is bonded to hydrogen, a dipole develops causing the hydrogen to be partially positive while the other atom is partially negative.
Thus, this accounts for high boiling point in compounds that contains hydrogen bonds.

hope this helps :)
There are two electrons in a covalent bond.
Deeper meaning:-A covalent bond can be meant of as a 'shared pair' of electrons, so there are 2 electrons in each bond. This means that a double bond will have 4 electrons in the space between the bonded nuclei, and a triple bond will have 6.
