The beta-lactam group of antibiotics such as penicillins (i.e. Amoxicillin), cephalosporins (i.e. Cefuroxime), and carbapenems (i.e. Meropenem) is the most widely used group of antibiotics. Beta-lactams are bactericidal. Beta-lactams have no innate resistance to beta-lactamases (enzymes produced by bacteria to break down beta-lactam antibiotics), but they can be paired with a beta-lacamase inhibitor such as Clavulanic acid. Later generations of beta-lactams may offer resistance to beta-lactamases. Beta-lactams offer activity against a broad spectrum of bacterial pathogens, including gram-positive, gram-negative, and (in higher doses, such as Cefazolin) anaerobic coverage.
Answer:
Explanation:
Using the Mendelian approach to solve this question, we will understand that the mendelian approach has a pattern for inherited traits.
From the data set given, the total number of the population is:
43+9+32+110 = 194
However, their ratio are being calculated as follows:
43/194 = 0.22
9/194 = 0.05
32/194 = 0.16
110/194 = 0.57
After comparison with the Mendelian's approach, we realize that these results seem to be similar to the 9:3:3:1 ratio.
i.e.
3/16 = 0.18
1/16 = 0.06
3/16 = 0.18
9/16 = 0.56
The inheritance pattern obviously dictates that the flax experiment proceeds in the pattern found in the Mendelian's Approach and the resistance of the two different strains were arbitrated by two traits.
Answer: <u><em>All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species.</em></u>

Answer:
I believe it would be these:
He can replace the 1.5-volt battery with a battery of higher voltage.
He can use a longer piece of wire that wraps more times around the bolt.
I'm not sure the others would work
Answer:
Independent variable: Glass of milk
Dependent variable: Time of sleep
Control variable: same type of milk
Explanation:
Independent variable in an experiment refers to the variable that the experimenter manipulates or changes in order to get a response in another variable (dependent). In this case, the independent variable is the GLASS OF MILK taken before bed.
Dependent variable is that variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the TIME OF SLEEP of the students.
A control variable or constant is the variable that is kept unchanged throughout the course of the experiment in order not to alter the outcome of the experiment. In this experiment, a control variable can be the SAME TYPE OF MILK taken by each student.
