Why can water have no net charge but have slight
charges in different parts of the molecule?
Answers
Water molecule is made up of one atom of oxygen and two atoms of hydrogen. The water is a polar compound and has slight charges due to differences in the charges.
Water molecule is composed of hydrogen and oxygen and is inorganic transparent liquid. The hydrogen and oxygen in a water molecule are linked by covalent bonds.
The oxygen is electronegative and attracts electrons. There is however no overall charge on the water molecule, but atoms of the compound have slight charges.
The unequal sharing of electrons between hydrogen and oxygen can give them slight positive and negative charges, respectively.
Thus, there are slight charges present on oxygen and hydrogen.

Students in a biology class were discussing outbreaks of food-borne illness. Modern practices of refrigeration are aimed at curbing (limiting) these bacteria. They wanted to know exactly what happened to bacterial colony growth at varying temperatures. The teacher explained that scientists study bacteria in the laboratory by counting colonies that grow on plates filled with agar, which is a nutrient substance. “Design” an appropriate experiment that would test the effect of temperature on bacterial growth. You would have a period of 5 days to conduct an experiment.

Answer:
I know this isn't a big help answer, but you could use it as a start. You could say something like "I tested it in multiple different temps. including .... (any temps. you want) Then say how all of thoose different temps. changed the bacteria." I hope it helped! :)
Explanation:
Most of the foodborne diseases are caused by those bacteria that can grow well and infect food at normal temperatures, and their population can be controlled by lowering the temperature or raising the temperature too high, which can degrade their cell walls.
What is the effect of temperature on the bacteria?There are numerous bacteria that can infect food and cause foodborne disease when consumed by humans, resulting in diarrhea, stomach aches, and other symptoms. Because most of these bacteria grow at room temperature, keeping food at that temperature degrades it faster, so foods are kept and stored in the refrigerator. This low temperature keeps the cellular activity of bacteria low; as a result, the bacteria cannot produce toxins or grow their population.
Due to this, the refrigerator stores the food for a longer time. Different strains can be kept and stored at different temperatures on an agar plate, but a strain present at a low temperature will produce far fewer colonies than one present at a room temperature. Further the growth depends upon the types of bacteria.
Hence, by refrigerating the food, cellular activity is seized and controlled.

Identify the independent variable by highlighting it red. Identify the dependent variable by highlighting it yellow. 1. If I increase the temperature of the seeds, then germination will increase,
Answers
Answer:
Independent variable: temperature ; Dependent variable: germination
Explanation:
The independent variable is what is being changed in an experiment. The dependent variable is what you are measuring in an experiment.
When the independent variable is changed (in this case, temperature), it effects the dependent variable (germination).

B.a halt in cell division
C.a failure in mitosis
D.slower growth
Answers
Answer:
This process is akin to searching for the proverbial needle in a haystack, because many of the mutations present in these cells have little to nothing
Explanation:
During mitosis, normal cells undergo checkpoints that monitor the fidelity of the processes that occur during the cell cycle. Uncontrolled cell growth refers to the breakdown of these regulatory checkpoint mechanisms.
In the cell cycle of typical cancer cells, mutations most like cause UNCONTROLLED GROWTH (Option A).Apoptosis refers to the programmed cell death that prevents the uncontrolled growth of cancer cells.In cancer cells, genes that control apoptosis during the cell cycle suffer mutations, thereby leading to uncontrolled cell growth.In conclusion, in the cell cycle of typical cancer cells, mutations most like cause UNCONTROLLED GROWTH (Option A).

Answers
Answer:
tend to split apart along bands
Explanation:
Foliated rocks are metamorphic rocks that are formed due to high pressure and heat leads to the layered or banded appearance of the rocks.
Due to the layered or banded appearance of the rocks, foliated rocks tend to split apart along bands that are aligned parallel to the minerals in the rocks. Example of foliated rocks: Slate, that split into thin sheets along bands .
Hence, the correct answer is "tend to split apart along bands ".

B) These are configurations of carbon and they have 6 protons and 6 neutrons but each contains a difference number of electrons - 8, 7, and 6 respectively. Eliminate C) These are isotopes of carbon and they all contain 6 protons and 6 electrons but each contains a difference number of neutrons - 6, 7, and 8 respectively. D) These are allotropes of carbon and they consist of 6 protons and 6 electrons but each contains a difference number of neutrons - 8, 7, and 6 respectively.
Answers
Answer:
C.
Explanation:
All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).
Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.
In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.
In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.
In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.
Answer:
These are isotopes of carbon they both contain 6protons and 6electrons but each contains a diff about of neutrons 6,7 and 8 respectively
