Solution B: 2.64 (m/v) glucose

Solution D: 9.4% (m/v) glucose

Solution E: 5.0% (m/v) glucose and 0.9% (m/v) NaCl

What is the solubility of CO2 in a soft drink (which is mainly water) that was bottled under a CO2 pressure of 4.5 atm?

The solubility of CO2 gas in water is 0.15 g/100 mL at a pressure of 760 mmHg?

Calculate the mass percent of a solution that is prepared by adding 27.4 g of NaOH to 257 g of H2O .

A balloon is floating around outside your window. The temperature outside is -17, and the air pressure is 0.700 . Your neighbor, who released the balloon, tells you that he filled it with 3.10 of gas. What is the volume of gas inside this balloon?

A chef needs to mix a 45% fat content cheese with a 20% fat content cheese to obtain 30 grams of a cheese mixture that is 30% fat. How many grams of the 45% fat content are needed? (Round to the nearest whole number)

The answer choices are

18 grams

15 grams

12 grams

17 grams

None of the Above

I already know what the answer is, I just need to find out how do you get that answer

How does the simple primary and secondary structure of DNA hold the information needed to code for the many features of multicellular organisms?

A.) The hydrogen bonding among backbone constituents carries coded information

B.) The base sequence of DNA carries all the information needed to code for proteins.

C.) The covalent bonding among backbone constituents contains the information that is passed from generation to generation.

D.) The amino acids that make up the DNA molecule contain the information needed to make cellular proeins.

What do I do? I have that kind of radio system and I want to be able to connect and listen to my ipod. How do I do that?

sweat pants, hair ties, chillen with no make-up on, thats when you're the prettiest, I hope that you don't take it wrong

What song is this?

-Process requires input of 2 ATP to activate.

Just tell me the number and how you came up with that answer

-Saturated; even numbered fatty acid

-Process requires input of 2 ATP to activate.

Just tell me the number and how you came up with that answer.

Given whatever you know, what do you consider to be the answer to our growing energy crisis? Remember that petroleum is used more for automobiles, but that's where most of it goes. As part of your answer, talk about alternative fuels and hybrid vehicles.

A) functions as a second messenger molecule.

B) serves as a receptor for various signal molecules.

C) adds a phosphate group to target molecules.

D) produces second messenger molecules

A) The receptors can be stimulated to exit to the membrane surface under conditions in which a cell needs to be regulated by the steroid hormone.

B) Steroid hormones are lipid soluble and thus can readily diffuse through the lipid bilayer that makes up the cell membrane.

C) The receptors are repressible, meaning they are actively altering cell function unless the target hormone is present.

D) Cells with steroid hormone receptors inside the cell are not able to respond to steroid hormones.

A) It regulates movement of materials across the nuclear envelope.

B) It assembles ribosomes from raw materials that are synthesized in the nucleus.

C) It synthesizes components of the endomembrane system.

D) It synthesizes and repairs DNA.

A) They both have their own DNA.

B) They both have multiple membranes.

C) They are both part of the endomembrane system.

D) They are capable of reproducing themselves

A) They are foreign proteins.

B) They lack nuclear localization signals (NLS).

C) They are defective proteins.

D) They have been tagged for destruction

A) Ribosomes that exit the nucleus through the nuclear pore complex attach to ribosome receptor locations on the endoplasmic reticulum, thus providing a means of communication between the two structures.

B) The inner and outer bilayers of the nuclear envelope are separated by a space that is continuous with the space inside the endoplasmic reticulum, thus providing direct contact between the two structures.

C) The nucleolus is present in the nucleus, but communicates directly with the endoplasmic reticulum.

D) The nuclear lamina anchors the endoplasmic reticulum, providing structural support and communication through direct contact.

Hormones are chemical substances produced in one organ that are released into the bloodstream and affect the function of a target organ. For the target organ to respond to a particular hormone, it must ________.......

A) have the same genetic makeup.

B) be from the same cell type as the organ that produced the hormone.

C) be experiencing a disruption in homeostasis.

D) have receptors that recognize and bind the hormone molecule

A) The receptors can be stimulated to exit to the membrane surface under conditions in which a cell needs to be regulated by the steroid hormone.

B) Steroid hormones are lipid soluble and thus can readily diffuse through the lipid bilayer that makes up the cell membrane.

C) The receptors are repressible, meaning they are actively altering cell function unless the target hormone is present.

D) Cells with steroid hormone receptors inside the cell are not able to respond to steroid hormones
