Answer:
a) Percent recovery
100%, 70.58%, 4.11%, 1.29% , 0%
b) MBC = 160 ng mL
c) Static
Explanation:
A) Calculate the percent recovery for each group
i) for 0ng mL
( 3.4*10^5 / 3.4*10^5 ) * 100 = 100%
ii) for 10ng mL
( (2.4 * 10^5) / (3.4 * 10^5) ) * 100 = 70.58%
iii) for 20ng mL
( ( 6.4 * 10^5 ) / ( 3.4 * 10^5 ) ) * 100 = Nil
iv) for 40 ng mL
( ( 1.4 * 10^4 ) / ( 3.4 * 10^5 ) ) * 100 = 4.11 %
v) for 80 ng mL
( ( 4.4 * 10^3 ) / ( 3.4 * 10^5 ) ) * 100 = 1.29%
vi) for 160 n mL
percentage recovery = 0%
B) what is the MBC
The value of MBC = 160 n mL because at this concentration CFU/mL = 0
c) determine if the antimicrobial tested is static or cidal
condition : If, the ratio of MBC : MIC is ≤4 then novel compound is Cidal
MBC / MIC = 160ng / 10ng = 16 : 1
hence we can conclude that the antimicrobial tested is STATIC
Which statement is true about the energy level of solids?
A.) Solids have more energy than water
B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.

Using the __________ system, kingdoms are grouped based on cell structure and type, while the __________ system groups major taxonomic groups into three major domains.
Given what we know, we can confirm that using the using the Whitaker system, kingdoms are grouped based on cell structure and type, while the whoese-fox system groups major taxonomic groups into three major domains.
What is the Whitaker system?The Whitaker system is a classification system to order and organize the diverse biological life found on Earth. This is the most commonly-known system which orders organisms into the 5 kingdoms. What is the Whoese-fox system?This is a much less popular system of classification for biological life. It is considered to be much less specific, containing only 3 groupings.Therefore, we can confirm that based on the statement, the spaces missing correspond to the scientists for who the systems are named after, which are Whitaker and Whoese-fox.

elect the correct statement regarding the lungs. Select one: a. The left lung is larger than the right lung. b. Only the right lung has a hilum. c. The left lung contains three lobes while the right lung contains two lobes. d. The left lung has more bronchopulmonary segments than the right lung. e. The left lung contains two lobes while the right lung contains three lobes.
Answer:
The right lung is smaller than the right to make room for the heart.
Explanation:
so the answer is A :)
The left lung contains two lobes while the right lung contains three lobes. Therefore option E is correct.
The statement that the left lung contains two lobes while the right lung contains three lobes is correct.
The right lung is divided into three lobes: the upper lobe, middle lobe, and lower lobe. On the other hand, the left lung is divided into two lobes: the upper lobe and lower lobe.
This anatomical difference is due to the position of the heart, which is located more towards the left side of the chest. The presence of an additional lobe in the right lung allows for a better fit around the heart.
Understanding the lobes of the lungs is important in assessing and diagnosing respiratory conditions and in surgical procedures that involve lung resection or transplantation.
Therefore option E The left lung contains two lobes while the right lung contains three lobes is correct.

The diagram shows the reproductive system of a plant.
Which of the following best describes the interaction that occurs between a plant's reproductive parts during self-fertilization?
Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.
Pollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
The correct answer is pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
This option correctly defines the interaction that occurs between a plant's reproductive parts during self-fertilization as it explains the pollination process and fertilization, when pollen grains are released then are transferred to the stigma the pollen tube is there that reaches ovule and the sperms fertilize an egg.
What is pollination?
Transfer of pollen from anther to the stigma of plants. Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.

describe the mechanism of blood sugar regulation (20 marks)
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
The pancreas releases glucagon when glucose levels fall too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells.p
