Do you predict that salt will be able to move across the membrane?

3 0

Answer: The correct answer is

No, because NaCl is Ionic

Explanation:

NaCl can pass through the cell membrane because it is Ionic and separates into Ionic components Na+ Cl+.

Cell membrane are phospholipids bilayers and have hydrophobic tails and face inside of the cells . The fatty acids tails are non polar and only non polar substances can pass through it but salts is a polar molecules because it is an ion and cannot pass.

astraxan [27]
If B and b are the two alleles , B + b = 1 and B ^2 +2 Bb + b ^2 = 1.

If 16% of mice are homozygous black , B ^ 2 =0 .16, meaning B = 0 .4 and b = 1 - 0. 4 = 0 .6 .
Answer = Notice how you don't even need to know that 24% of the mice are heterozygous .

DNA is a nucleic acid involved in heredity, or the passing down of genetic traits from one generation to the next. DNA consists
Phoenix [80]

Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).

The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:

-<u>Adenine</u> is paired with <u>Thymine</u> (think of A for apple and T for tree)

-<u>Cytosine</u> is paired with <u>Guanine</u> (think of C for car and G for garage)

What is the rule of proteins?
Roman55 [17]

The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids.) The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.

1. A normal mammalian cell will shrink if it is placed into_________. (Assume all solutes are non-penetrating) A. pure water B.
GrogVix [38]

Answer:

B. 50 mM glucose; E. 300 mM glucose

Explanation:

In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.

The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.

The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.
