The elements potassium (K) and chlorine (CI) can form an ionic bond. Which of the following
statements correctly explains what occurs (in this ionic bonding)?
1.) As chlorine has 7 valence electrons, it tends to form bonds to gain one electron (to get a full valence shell of 8).On the other hand, potassium has one valence electron, so it tends to lose this electron to other atoms (and
become a cation)
2.) As chlorine has 7 valence electrons, it tends to form bonds to lose all 7 electrons. On the other hand,potassium has one valence electron, so it tends to gain 7 electrons (to get a full valence shell of 8).
3.) In this ionic bonding, potassium is the anion and chlorine is the cation.
4.) During the ionic bonding between potassium and chlorine, 8 electrons are shared between these 2 atoms.

A cell membrane is very specific about what it allows across. How does t help the cell? ​

Answers

Answer:

Explanation:

The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled

Which statement is the first step of protein synthesis?(1 point) A ribosome attaches to the mRNA. DNA unzips between the base pairs. tRNA carries amino acids to the ribosome and attaches it to the mRNA strand. Amino acids are linked together with peptide bonds.

Answers

Answer:

DNA unzips between base pairs.

Explanation:

This is the first step of protein synthesis.

The first step of protein synthesis is attachment of mRNA to ribosomes. Option A is correct.

Protein synthesis:

It is known as translation. In this mRNA is translated in to the sequence of amino acids which ultimately form protein.

First mRNA attach to ribosome,tRNA bring amino acid to ribosomes and attach to mRNA.Amino acids bond together via peptide bond.

Therefore, the first step of protein synthesis is attachment of mRNA to ribosomes.

Which of the following are the best sources of longer-term, stored energy for our bodies?
A. Monosaccharides
B. Disaccharides
C. Polysaccharides

Answers

The answer is gonna be A

The best source of longer-term energy storage for our bodies are Polysaccharides. Option C is correct.

Saccharides are sugar molecules. Among these molecules, some are shorter than others though all of them provide very similar functions to our bodies. Our bodies break down these sugars in order to obtain energy.

Due to the nature of everyday life, our bodies at times need a quick source of energy, as well as energy to be stored for later. This is where the difference in saccharides comes into play. Monosaccharides and Disaccharides are a source of quick energy, due to their being short molecules they can be broken with ease for quick use.

On the other hand, Polysaccharides are chains of sugar that can at times span into the thousands. These chains are later quickly broken up into monosaccharides at times of need. This characteristic makes them ideal for long-term storage of energy and is the reason that option C is correct.
