Answer:
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Explanation:
You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),
which is used frequently in biological experiments.
Based on your answer above, what is the value of x?
Solution:
A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.
250 ml = 0.250 liter
Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose
Recall:
Mass = number of moles * mass of 1 mole
mass of 1 mole of C12H22O11
= 12(12) + 1(22) + 16(11)
= 144 + 22 + 176
= 342 grams
Mass = 0.1375 * 342 = 47.025 grams of sucrose.
Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
Answer:
The Chromosomal Theory of inheritance, proposed by Sutton and Boveri, states that chromosomes are the vehicles of genetic heredity. Neither Mendelian genetics nor gene linkage is perfectly accurate; instead, chromosome behavior involves segregation, independent assortment, and occasionally, linkage.
Bacteria without plasmid will only grow in the media without penicillin since it doesn't have immunity.
Bacteria with recombinant plasmid with VGP gene, n<span>on-recombiant plasmid, Recombinant plasmid but no vgp gene can grow in both media(with or without penicillin) because they can withstand penicillin.</span>
It means to change the looks of the landscape. Or changes in the landscape.
The answer is A. The mutation of the gene was a beneficial
one. It happened in a few individuals
and increased their survival rate. The mutation
was also inheritable hence was passed down generations. The new gene probably altered a protein involved in
metabolism. There are two other types of mutations;
deleterious and neutral.
