Answer:
If a negatively charged ion is more concentrated outside the cell, the forces required to balance the chemical gradient would be directed <u>outwards</u>. Thus, the equilibrium potential for this ion would be <u>negatively</u> charged.
Explanation:
The resting membrane potential is normally due to small excess of negative ions inside of positive ions outside the cells.
The negative charges are attracted to the positive charges and they form a thin layer of negative inside and positive outside of the cell. The rest of extracellular and intracellular fluid remains normal.
If negatively charged ion is more concentrated outside the cell, then the forces will move outwards, in order to balance the gradient. Thus resulting in negative equilibrium potential (The potential at which no movement of the ion occur across the membrane)
Answer:
The most likely explanation for the truncated polypeptide -due to the substitution of cytosine for adenine- is that mutation introduced a stop codon in the middle of the gene.
Explanation:
A codon consists of three nucleotides -in the RNA chain- whose order determines a specific amino acid. Not all codons code for amino acids, as there are termination codons, also called stop codons, which are UAG, UGA and UAA.
If in Manny's computer model, the substitution of cytosine by adenine produced a termination codon, the synthesis of a peptide is stopped prematurely resulting in a truncated peptide.

Out of the following given choices;
<span>A)
</span>They are all of the same species.<span>
B) They all require the same type of food.
C) They are part of a community.
D) They are abiotic factors in a forest.</span>
The answer is C. A community is
the summation of all the species population interacting in a habitat/ecosystem.
These interaction between the population could include commensalism, predation,
symbiosis, parasitism, and etcetera.
