Answer:
The correct answer is : proton and electron (opposite charges).
Explanation:
Water is a polar molecule as it has equal number of electron and proton. Electron and protons are present on different end of water molecule, negative charge due to electrons at end of oxygen, while positive charge at end of hydrogen due to protons.
Equal number of electron and proton make it neutral or no net charge molecule however having opposite charge on its end makes is polar.
Thus, the correct answer is: proton and electron.

Which of the following best describes a scientific theory?
a. It cannot be changed.
b. It explains very few observations.
c. It may change.
d. It is basically speculation.
Answer:D. It is basically a speculation
The best description of a scientific theory is It may change.
Option C is correct.
How do we explain?A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Scientific theories are not facts, but they are based on facts.
Scientific theories can change if new evidence is found that contradicts the theory. For example, the theory of gravity was once thought to be absolute, but new evidence has shown that gravity is not constant, but varies depending on the mass of the objects involved.
Option C is correct.

If two events are correlated, what must be true?(1 point) One event caused the other. Both events have the same result. Both events have the same cause. The events tend to happen together
Answer:
One event caused the other
Explanation:
A correlation refers to how related are two or more variables among each other.
Two events are correlated if the result of one of them depends on the result of the other event. Also, the probability of one of them happening will be conditioned by the occurrence of the other event.
There are different types of correlation. When two correlated variables or events have a causal relation, this means that one of them occurred because the other one occurred first. For example, let us think about a dolphin cranium. We might measure two variables, the rostrum length and the skull length. The longer the rostrum is, the longer the skull will be. The occurrence of a longer rostrum implies a longer skull. This two events are positively correlated.
Although not every correlated event is due to causality, whenever causality occurs between two variables, it means that they are correlated.

If you wrap your snacks in aluminum foil, will they still be stolen by seagulls at the beach? A. If snacks are wrapped in aluminum foil, then the snacks will not be eaten by seagulls. B. If the snacks are not eaten by the seagulls, then the snacks are wrapped in foil.
Answer:
The correct option is;
A. If snack are wrapped in aluminium foil, then the snacks will not be eaten by seagulls
Explanation:
It has been observed severally that birds including seagull tend to avoid shiny objects. As have been proven by research, birds are not drawn towards shiny materials and shiny articles can be used to scare off birds. Articles like CDs, plates of aluminium and tinfoil and be arranged so as to be glaring in order to ward of the birds
Similarly, placing shinny articles around a property keeps away.

Debido a que las células de los hongos están cubiertos por una pared celular estos no tienen la capacidad de incorporar moléculas grandes y otros organismos sino que deben ingerir su alimento antes de absorberlo este tipo de digestión se denomina A. Intracelular B. Extracelular C. Quimica D. Mecanica
Answer:
B
Explanation:
Extracellular digestion is a form in which lager molecular food substances are first digested by chemical activities of enzymes and acids outside the cells,before been absorbed into the body cells.
Fungi are examples of organism with this mode of digestion. They use external source of energy to breakdown the food substances before digestion.They are called heterotrophic organism because they can not manufacture their food ,but rather depend on external source of energy derived from the organic matter from the host they feed live on,
The energy sources are the carbohydrates and proteins from the host.
he x-ray film shows a fracture where one side of the cortex is intact and flexed and the other side has signs of interruption (fracture). Which term best describes this type of fracture
Answer:
This is refers to as Greenstick fracture.
Explanation:
This is the type of fracture common in children less than 10 years, in which there is incomplete fracture of the bone,with ,but the cortex remain flexed.It is called green stick because it is analogous to the act of breaking a branch of a tree, which is not completely broken, from the main branch.
It is usually to due to falls,and common in kids because of their soft bones which is not completely formed and therefore will not break off completely like that of adults when fractured, but only from one side only.

During the experiment, black pepper was added to the water as it boiled strongly, and the pepper moved in a circular pattern from the top
of the water to the bottom and back again. What does the circular pattern of the pepper represent?
The circular pattern of the pepper represents the convention currents that exists in boiling water as it is heated.
What are convection currents?A process that involves the transfer of energy from one location to another is a convection current.
Convection currents are caused by variations in fluid density brought on by temperature gradients. A natural convection current is the phenomenon that arises from the constant replacement of the heated fluid in the vicinity of the heat source by the adjacent present cooler fluid. Natural convection heat and mass transfer refer to the improved heat and mass transmission caused by this natural convection current.

Malthus' ideas regarding supply and demand influenced Darwin because limited natural resources force individuals to _______ with each other, and not every individual will have the opportunity to reproduce.
Answer:
compete
Explanation:
Limited natural resources force individuals to compete with each other and only strong individuals are able to compete and thereby reproduce effectively.
According to Malthus, population growth has the capacity to outrun the supply of food, and hence, if humans must experience better living conditions, there should a form of population control by controlling the birth rate.
Darwin extrapolated from Malthus' idea and opined that limited natural resources will only make individuals compete with each other and in this capacity, weak individuals might not be able to effectively compete, thus, leading to weakness in reproducing.

Explain how this experiment disproves the theory of spontaneous generation.
Answer:
The theory of spontaneous generation was suggests that the living organisms can come from inanimate objects, however it is an obsolete theory that is disproved by many experiments. The very first experiment that disapproved it was the experiment by Francesco Redi in 1668.
He demonstrated that maggots come from the eggs of flies instead of rotting meat. He placed raw meat inside of every jar. Half the jars he left open and the other half, he covered with mesh. In open jars he found maggots after some time but covered jars have no maggots. That proved that the maggots come from eggs of flies rather than rotten meat.

Which is a property of water? A: it is a crystalline at room temperature, B: it expands as it melts, C: it dissolves non-polar substances, D: it has a large capacity to hold heat
Answer: D: it has a large capacity to hold heat
Explanation:
The property of water is that it has a large capacity to hold heat. It should be noted that in order to increase the temperature of water to a certain degree, it requires a lot of energy thereby water helps to regulate the temperature.
Other properties of water are that it is an excellent solvent, it is polar, it has adhesive and also cohesive properties.

The possibility that Mongolian ruler Genghis Khan spread an unusual chromosome to nearly 16 million men living today resulted from studies of ________.
A) proteomics
B) plasmids
C) the X chromosome
D) the Y chromosome
Answer:
D. the Y chromosome
Explanation:
Men have an X and a Y chromosome while women have two X chromosomes. Since the unusual chromosome was spread to nearly 16 million men, it was most likely a Y-linked trait as only men inherit a Y chromosome. If it was an X-linked trait, both men and women would be able to get it since both inherit X chromosomes.
