False. Probably I don’t have much context
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 cellular process that enables the cells to grow and develop into tissue is called MITOSIS.
Explanation:
The skin is the largest organ of the body that contains various cells which includes: the epidermal and dermal cells. With the various activities of man, the skin is susceptible to injury through burns.
The healing of the skin, especially injury sustained from burns involves the interaction between the different cell types. Recently, scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries which are grown from living cells.
MITOSIS is the cellular process that enables the cells to grow and develop into tissue. It is also defined as the process by which a cell duplicates into two genetically identical daughter cells.
The process of mitosis occurs in 4 stages; the prophase, metaphase, anaphase, and telophase. The various activities that occurs on these stages brings about the growth and the development of the cells into tissue.
The correct answer is choice B, Tt. I hope this helps.
Answers: A. (DNA replication is semiconservative), B. (DNA is replicated so that each daughter cell will have half of a DNA molecule), and C. (The cell enters S phase with two copies of each of its chromosomes)
