Explanation:

Carbonic anhydrase (CA; carbonate hydro-lyase) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<-->HCO3(-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.

The zinc ion is located in a cone-shaped cavity and coordinated to three histidyl residues and a solvent molecule. Inhibitors bind at or near the metal center guided by a hydrogen-bonded system comprising Glu-106 and Thr-199. The catalytic mechanism of CA II has been studied in particular detail. It involves an attack of zinc-bound OH- on a CO2 molecule loosely bound in a hydrophobic pocket. The resulting zinc-coordinated HCO3- ion is displaced from the metal ion by H2O. The rate-limiting step is an intramolecular proton transfer from the zinc-bound water molecule to His-64, which serves as a proton shuttle between the metal center and buffer molecules in the reaction medium.

Protozoa are unicellular eukaryotes. As in all eukaryotes, the nucleus is enclosed in a membrane. ... The organelles of protozoa have functions similar to the organs of higher animals. The plasma membrane enclosing the cytoplasm also covers the projecting locomotory structures such as pseudopodia, cilia, and flagella

According to the research, the structures common to all protozoa are a group of cells that are identical to each other.

They are unicellular organisms whose entire body is a single cell, endowed with organelles and diverse structures, which fulfill nutritional, mobile, etc. functions.

The common thing is that protozoa are unicellular organisms of the eukaryotic type that develop in water.

Therefore, we can conclude that according to the research, the structures common to all protozoa are a group of cells that are identical to each other.

Answer:

B. it combusts

Explanation:

Water doesn't combust since it isn't flammable. Hydrogen is flammable, but oxygen isn't.

Water=H2O.

1.    0.917 M    

2.   0.268 M

1.  Finding number of moles of KCl

Number of moles of KCl = (mass of KCl) / (molar mass of KCl)

Number of moles of KCl = 10.25 g / 74.55 g/mol

Number of moles of KCl = 0.1376 moles

Then converting ml to L;

Volume of solution = 150 mL

Volume of solution = 0.150 L

Now we can calculate the molarity:

Molarity = (moles of solute) / (volume of solution in liters)

Molarity = 0.1376 mol / 0.150 L

Molarity = 0.917 M

Therefore, the molarity of the solution is 0.917 M.

2.Number of moles of Ca(OH)2 = (mass of Ca(OH)2) / (molar mass of Ca(OH)2)

Number of moles of Ca(OH)2 = 5 g / 74.09 g/mol

Number of moles of Ca(OH)2 = 0.067 moles

Convert the volume of the solution (in milliliters) to liters:

Volume of solution = 250 mL

Volume of solution = 0.250 L

calculate the molarity:

Molarity = (moles of solute) / (volume of solution in liters)

Molarity = 0.067 mol / 0.250 L

Molarity = 0.268 M

Therefore, the molarity of the solution is 0.268 M.

Explanation:

Electron transport chain is the process which yield the most number of ATP as compared to all three major phases of cellular respiration. Glycolysis produces only 2 ATP from the breakdown of molecule of glucose. In the Krebs cycle, one GTP which is an ATP equivalent is produced from the breakdown of one glucose molecule while on the other hand, 32 ATP molecules are produced from the breakdown of one glucose molecule.

There are 12 chromosomes in each daughter cell, each made up of two chromatids. Every chromosome is one of two homologous pairs.chromosomes from the parent cell.

There are typically 23 chromosome pairs in each cell of the human body (46 total chromosomes). The father contributed the other half, while the mother contributed the first half. Your sex at birth—whether you are a boy or a girl—is determined by two chromosomes, the X and the Y.

Since each human cell contains 23 chromosomes of these chromosomes, there are 46 diploid human cells and 23 haploid human cells. There are 23 pairings in total, 22 of which are considered autosomes. The 23rd pair of chromosomes, also known as the 'X' & 'Y' chromosomes, controls sexual orientation.
