to be more resistant to that antibiotic
if an antibiotic eliminates 99.9% of the germs. It makes sense to assume that the new strain of bacteria will be more resistant to that drug than the old strain. Here the correct option is A.
The majority of the susceptible bacteria in the population are killed by the addition of a bactericidal antibiotic, while the resistant bacteria continue to exist. Only the resistant bacteria will continue to grow and multiply while being exposed to the antibiotic.
Antibiotic misuse, overuse, and ineffective infection prevention and control all contribute to the acceleration of antibiotic resistance. At all societal levels, actions can be made to lessen the effects and contain the spread of resistance.
Thus the correct opion is A.

Two normal parents produce a child affected with the autosomal recessive disease homocysteinuria. They want to have 3 more children. You tell them the chance of 1 OR MORE affected among the next three children is:
Answer:
Zero
Explanation:
Because in a situation whereby both parents are carriers of an autosomal recessive condition there is a 1 in 4 chance of them having an affected child.
Hence, given that these two normal parents have already had one affected child with the autosomal recessive disease homocystinuria. There is ZERO chance of having an affected child in the next three kids they will be having.

Why has the Ugandan government pushed Abstinence as a means of combating the spread of HIV/AIDS?
On a separate piece of paper, construct a population pyramid to illustrate the current age groups infected by HIV/AIDS in Uganda.
1. A reexamination of HIV seroconversion studies suggests that condoms are 90 to 95% effective when used consistently, i.e. consistent condom users are 10 to 20 times less likely to become infected when exposed to the virus than are inconsistent or non-users.
The main reason why has the Ugandan government pushed Abstinence as a means of combating the spread of HIV/AIDS is: the people for whom the propaganda is done are mostly children above 10, who tend to start having sx at an early age.
Why has the Ugandan government pushed Abstinence as a means of combating the spread of HIV/AIDS?The ABC strategy is credited for bringing the HIV/AIDS epidemic under control in Uganda.

Let's start with a ham and cheese sandwich with lettuce and pickles. As I bite into my sandwich the teeth are present for mastication to begin the process of mechanical digestion and the saliva begins to mix with my food where salivary amylase is present and starts the digestion of the starchy bread. What happens next? (Think about the carbohydrates, proteins and fat in our sandwich
Answer:
Explanation:
After amylase act on carbohydrates, the chyme pass through the oesophagus down to the dudoneum in the small intestine. Amylase also continue to break it down into disacharrides and enzymes like maltase, sucrase and lactase are released to further break it down into maltose, sucrose, and lactose then finally glucose, a way it can be absorbed easily by the epithelial walls.
The digestion of lipids and protein begin in the dudoneum of small intestine.
Trypsin act on protein and break it down to peptides. Peptidase is then released and break it to single chain peptides bond. In the small intestine, dipeptidases break it down into amino acids easily absorbed by the epithelial walls.
The bile in the gall bladder produce enzyme called lipases which breakdown lipids and make it to undergo emulsification.

Small, reduced leaves with a single vein occurring in the club mosses
Answer:Club mosses are low evergreen herbs with needlelike or scalelike leaves. Many species have conelike clusters of small leaves (strobili), each with a kidney-shaped spore capsule at its base. The plants are homosporous, meaning they produce just one kind of spore
Explanation:Although they lack true veins, many species of mosses have long narrow cells in their stems, the midribs of their leaves, and their rhizoids (root-like plant tissue) that can be considered evolutionary precursors to true veins. Vascular plants with true veins include the clubmosses, ferns, and flowering plants.
Select all that apply.
Characteristics of meiosis include_____.
1) The most common kind of cell division
2) Four daughter cells produced when parent cells divide
3) same number of chromosomes in each daughter cell as in a parent cell
4) different DNA in the daughter cell than in the parent cell

Gene regulation is a section of the DNA that contains the genes for the proteins needed for a
specific metabolic pathway.
A True
B False
Answer:
The correct answer is - B. false.
Explanation:
A section or segment of the DNA that contains the genes for the proteins needed for a specific metabolic pathway is called an operon. Gene regulation on other hand is the process of an organism to control which genes are transcribed.
Gene regulation is the ability of turning the genes on or off for transcription. It is regulated by various ways such as chemically modifying genes and using regulatory proteins.
Who do we balance a chemical equation
Answer:
We have to balance chemical equations because you need to satisfy the law of conservation of matter. That states that matter cannot be produced or destroyed in a closed system. The law of conservation of mass governs the balancing of a chemical equation.
Answer:
I think you meant how?
Explanation:
but always you balance a chemical equation by looking at how many atoms you have for each element. For example we have the chemical equation Na + Cl2----> NaCl
so there's 1 Na atom
there's 2 Cl atoms
and for the product side
there's 1 Na atom
there's 1 Cl atom
TO BALANCE THIS you have to make the reactants side equals the product side by ADDING COEFFICIENTS.
so it would be 2Na + Cl2 ---> 2NaCl

Which of the following is a concern if you forgot to resuspend (mix) culture solutions when performing serial dilution?
A) Bacteria would no longer be able to grow on solid media
B) CFU/mL calculations would not be accurate
C) Colony morphology would be disrupte
D) The pure culture would be contaminated
Answer:
B) CFU/mL calculations would not be accurate
Explanation:
In microbiology CFU is the acronym for Colony Forming Unit, which indicates the number of bacteria or fungi capable of multiplying under suitable conditions. In this case, CFU/mL indicates how much bacterial or fungal cells, susceptible to reproduction, exist within 1 mL of a culture solution.
When this solution is used, to make a dilution or other laboratory activity, it is important that it be resuspended, that is, mixed, as the bacteria or fungus cells can accumulate in the bottom or surface of the substance, changing the value of CFU/mL and causing inaccurate dilutions if used. When resuspended, the substance presents the appropriate value of CFU/mL, ensuring that the dilution is accurate and effective.
