<h3><u>Answer;</u></h3>
<em>The overall or total charge becomes neutral, that is the total charge is Zero.</em>
<h3><u>Explanation;</u></h3>
- <u>Ionic compounds are compounds composed of ions, charged particles that form when an atom gains or loses electrons.</u> The charged particles are the positively charged ion known as cations and the negatively charged ion known as anions.
- <u>The overall or the total charge for the ionic compound must be neutral. This means that the sum of the charges from the cations and anions should add up to zero.</u>
Im not sure since i think we live in different country but, you can buy Curium at a shop which sell chemical products or usually people buy it online
I never heard Curium uses for our daily lives. Usually Curium used for chemical experiment. Scientists use it to test how much chemical elements in Mars.
Sorry if there's anything wrong
A carbohydrate composed of two covalently bonded simple sugars is called a <u>disaccharide</u>.
Carbohydrates or sugars are one of the four main categories of the macromolecules that make up living things (the other three being nucleic acids, proteins and lipids). It can either be a simple sugar (sugar monomer or monosaccharide) or a polymer of simple sugars.
Carbohydrates are composed entirely of carbon, oxygen and hydrogen atoms. Simple sugars or monosaccharides contain six carbon atoms, twelve hydrogen atoms and six oxygen atoms. When two monosaccharides bond covalently, they form a disaccharide.
Some examples of disaccharides include:
- Sucrose or table sugar - It is made up of one glucose molecule and one fructose molecule
- Lactose or milk sugar - It is made up of one glucose and one galactose molecule
- Maltose or malt sugar - It is made up of two glucose molecules.

Answer:
<u>d. Transport proteins within the membrane serve as a tunnel for molecules to enter the cell.
</u>
<u />
Explanation:
Solutes are typically moved across the cell through either passive or active transport. The cells, surrounded by a bilipid layer or plasma membrane is amphiphlic- its polar, hydrophilic lipid heads face outwards, while their non-polar hydrophobic lipid tails face inwards towards each other.
While lipid-soluble molecules move across the layer easily, it is also difficult for charged and also large molecules to move across its surface, into the cell. Transmembrane channels, <u>embedded within the membrane</u>, help to maintain selective permeability as transport proteins, pores and gated channels. Simple diffusion happens as a method of passive transport in cells through plasma membranes.
The solutes travel through the plasma membrane in the process of diffusion from regions of high concentration to regions of low concentration; this occurs without the use of energy. <u>Molecules moving against their concentration require active transport mechanism to cross the membrane</u>.
