How do electronegativity, polarity, and ph all relate and effect each other? I know moderators, you will be reported if you give a link or wasteful answer.
Answer:Electrons in a polar covalent bond are shifted toward the more electronegative atom; thus, the more electronegative atom is the one with the partial negative charge. The greater the difference in electronegativity, the more polarized the electron distribution and the larger the partial charges of the atoms.

A major difference between eukaryotes and prokaryotes is that __________. A major difference between eukaryotes and prokaryotes is that __________. some eukaryotic cells live in areas of temperature extremes whereas prokaryotic cells cannot prokaryotic cell structure is much more complex than eukaryotic cell structure eukaryotes were the first cell type on Earth eukaryotic cells contain the genetic material DNA whereas prokaryotic cells contain RNA eukaryotes' survival is limited to a few environments whereas prokaryotes have adapted to a variety of environments
Answer:
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.

Pls help me will give points
Answer:
D
Explanation:
D is my best bet because most have cilia and flagella to help move them around their environment.
A is for multicellular organisms, B occurs only in some unicellular but not all, C is for multicellular mostly (some unicellular can have it), but D applies to majority of unicellular (almost all have some sort of mechanism for movement)

how can you separate iron filings from sand through which process
Answer:
Process called magnetic separation
Explanation:
The magnetic separation is a process in which magnetically susceptible material is extracted from a mixture using magnetic force.
This method is also used to separate the mixture of sand and iron fillings as iron is attracted by magnet.
Answer:
Use a magnet to separate the iron filings from sand since iron is magnetic

Answer:
what is the question
A benefit of a diet high in carbohydrates is increasing muscle glycogen storage to prevent muscle fatigue.
What are carbohydrates?Carbohydrates are a type of macronutrient composed of one or more subunits called monosaccharides (eg. glucose).
Glycogen is a polysaccharide composed of many subunits of glucose monosaccharides.This polysaccharide (glycogen) serves as a storage of energy in different species of animals.In conclusion, a benefit of a diet high in carbohydrates is increasing muscle glycogen storage to prevent muscle fatigue.

Item 5 What is the role of a generator in producing electricity? The generator stores electrical energy for later use in homes and businesses. The generator spins the turbine to create mechanical energy. The generator transforms the mechanical energy of the turbine into electrical energy. The generator reverses the turbine to create electrical energy.
Answer:
The generator transforms the mechanical energy of the turbine into electrical energy
Explanation:
Electricity generator is a device that is used in generating power supply which can be used in industries, homes and for commercial and private purposes.
It operates by converting mechanical energy into electrical energy for the use in an external circuit. mechanical energy can be obtained from steam turbines, internal combusting energy, gas and water turbines and it can be obtained through the rotating shaft.
The capacity of each generator determines the amount of energy it can supply to a given place.
