Indicate whether the statements below are TRUE or FALSE.
1. You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose.
2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower.
3. When you have 1 liter of a solution containing 90g of glucose, you must use 171g of sucrose to make a 1-liter sucrose solution with the same molar concentration.

O 2, 4, and 5
O 1, 4, and 6
O2, 3, and 5
O 1, 3, and 6
The correct option is D.) 1, 3, and 6 because pressure is the changing factor in Gay-Lussac's Law, the constant factor in Boyle's Law, and the changing factor in Charles's Law.
Gay-Lussac's Law states that the pressure of a given quantity of gas held at constant volume is directly proportional to the Kelvin temperature which means the pressure of a gas increases as the temperature increases, and decreases as the temperature decreases.
Boyles Law states that the pressure of a gas is inversely proportional to its volume that means as the volume of a gas increases, the pressure of the gas decreases, and vice versa.
Charles's law is a basic physical law that states that the volume of a given amount of gas at a constant pressure is directly proportional to its absolute temperature. This means that when the temperature of a gas increases, its volume also increases, and vice versa.

Sometimes the leaves of plants contain white patches. The cells in this part of the plant most likely cannot
A: convert sugar into carbon dioxide and water
B: trap the Sun’s energy through photosynthesis
C: build proteins from amino acids
D: package materials for transport out of the cell
E: reproduce and divide by mitosis and cytokinesis
Answer:
d.
Explanation:
i hope this really help
The cell in the leaves of a plant that contains white patches will most likely be unable to trap the Sun’s energy through photosynthesis.
What is photosynthesis?Photosynthesis is the process whereby cells of a green plant obtain nutrition by utilizing energy from sunlight.
Photosynthesis takes place in an organelle of the cell called chloroplast. The chloroplast contains a pigment called chlorophyll that traps the energy from sunlight.
However, when the leaves of a plant are covered with white patches, this impedes the chloroplast from being able to trap the Sun’s energy through photosynthesis.

Imagine that fully functioning kidneys have been successfully created through bioengineering. What data analysis would measure the effectiveness of bioengineered organs in improving access to organ transplants among diverse groups of people, and what evidence would be needed to demonstrate that bioengineered organs have improved access
Answer:
The correct data analysis and evidence is:
Analysis: Compare the percentage of different ethnic groups who receive kidney transplants before and after bioengineered kidneys are available.
Evidence: A greater percentage of African Americans, Asians, and Pacific Islanders, and Hispanic/Latinos receive transplants after bioengineered kidneys are available compared to before
Explanation:
Bioengineered organs may be used to repair organs that have been destroyed. If the bioengineered organs are identical to the initial ones, transplantation rejection may be reduced.
So, to assess the effectiveness of organ donation adoption in people of various ethnicities, we should compare the percentage of people of various ethnicities receiving organ transplants before and after bioengineered organs became viable, and look for signs of a higher percentage of people of various ethnicities receiving organ transplantation after bioengineered organs became available.

A serial dilution is performed on a culture of Saccharomyces cerevisiae (Brewer's yeast). A 1:10 dilution was performed in series seven times. You plated and spread 100 microliters of the fifth dilution to a YEPD agar plate to grow overnight. After incubation, you count 142 colonies on the plate. What was the viable count of the stock culture
Answer: CFU/mL = 14200 CFU/mL
Explanation:
Microorganisms are very small and difficult to count directly. Instead, a laboratory technique is used to count CFUs (Colony Formation Units). This involves making dilutions of a microbial suspension and spreading it on thin layers of agar containing nutrients for growth in Petri dishes also called agar plates. After incubation under ideal conditions, some plates are completely covered with microbial growth; some have little or no growth; and some are covered with individual isolated "spots", which are microbial colonies. Since a colony may consist of a single organism or a group of microbes, the dots represent a CFU.
To calculate the viable count of the stock culture, you have to count the number of colonies, multiply by the dilution and the result will be the plate count in CFU.
So, the equation is:
CFU/mL = Number of colonies / (Volume trasferred to plate x dilution blank)
100 microliters = 0.1 mililiter
1/10 = 0.1 (dilution factor)
Replacing the information from the question:
CFU/mL = 142 / (0.1 mL x 0.1)
CFU/mL = 14200 CFU/mL
