Answers

Explanation:

anti=against

bio=living

organ system is formed from the organs supporting each other process.

because they lost the connection.

immue system.

photosynthesis.

1. No

2. Antibiotics cannot kill viruses because viruses have different structures and replicate in a different way than bacteria.

Antibiotics work by targeting the growth machinery in bacteria (not viruses) to kill or inhibit those particular bacteria.

When you think about it structurally, it makes sense that an antibiotic could not work to kill a virus with a completely different set of replicating “machinery”.

3. An organ is a part of the body that performs a special task to help the organism live while an organ system is a collective group of organs.

4. The breakdown of a particular organ system is not supposed to cause the breakdown of another except it performs a function needed for the other organ system to function.

What is the concentration of the CaCl2 (calcium chloride) salt solution if you are given 3.2g of CaCl2 and you add 4ml of water? The units for your answer should be mg/ml.

Answers

Answer:

800 mg/ml

Explanation:

Recall that: 1 g = 1000 mg.

Hence

3.2 g of CaCl2 =  3.2 x 1000 = 3200 mg CaCl2

mass concentration of CaCl2 = mass of CaCl2/volume of water

                                   = 3200/4 (mg/ml)

                                   = 800 mg/ml

Therefore, the concentration (in mg/ml) of CaCl salt solution formed by dissolving 3.2g of CaCl2 in 4 ml of water is 800 mg/ml.

The concentration of calcium chloride solution will be 800 mg/ml.

The calculation of the concentration of CaCl₂:

Based on the given information,

The mass of CaCl₂ given is 3.2 grams. The volume of water is 4 ml.

Now the concentration of CaCl₂ can be determined as,

Concentration = Mass/Volume

Now putting the values we get,

[tex]Conc = \frac{3.2 g}{4 ml} \\Conc = 0.8 g/ml\\Conc = 0.8 g * 1000 mg/ml\\Conc = 800 mg/ml[/tex]

Thus, the concentration of CaCl₂ is 800 mg/ml.

The enzyme carbonic anhydrase is a protein that binds to two small molecules: water and carbon dioxide. By holding the two molecules in the proper position, the enzyme allows the two molecules to react to form a product, carbonic acid. The enzyme then releases the product and becomes available to catalyze the same reaction once again. How does carbonic anhydrase change the reaction between carbon dioxide and water?

Answers

Answer:

Chemical groups on the surface of the enzyme reduce the reaction's ... 100,000 carbon dioxide and water molecules into carbonic acid every second but ... What fraction of energy available in the chemical bonds of glucose actually ... The resulting three carbon molecule, lactic acid, builds up as a waste product inside cells.

The hydrolysis of carbon dioxide into carbonic acid or bicarbonate would not occur without carbonic anhydrase. Therefore, only 15% of the carbon dioxide produced by the body would be removed from the tissues by the blood.

What is the importance of carbonic anhydrase?

At least 80% of the bicarbonate transported throughout the entire kidney occurs in the proximal tubule and is mediated by proton secretion.

Bicarbonate is created when carbon dioxide is hydrated by carbonic anhydrase and subsequently dissociates into hydrogen ions and bicarbonate.

As a result, they are categorized as metalloenzymes. The enzyme helps move carbon dioxide while preserving the acid-base equilibrium.

Therefore, Similar to other epithelial, carbonic anhydrase is widely distributed in renal tissue and works to catalyze the hydration-dehydration process of CO2.

Yosef is playing with a different kinds of rubber bands. Some are very narrow and some are quite wide. Yosef is curious about the rubber bands and develops the following scientific question: Does the width of a rubber brand affect how easy it is to stretch it?

He decides to develop a hypothesis to test this scientific question. What could Yosef’s hypothesis be?

Answers

Answer:

If the width of a rubber band is increased, then it will be more difficult to stretch because more force will be needed to stretch it.

Explanation:

true or false ? Cell membranes are selectively permeable, allowing only some materials to cross the cell membrane. This
property allows cells to maintain homeostasis.

Answers

Answer:

True

Explanation:

Cell membranes are selectively permeable because of the structure of the phospholipid bilayer.

This bilayer only lets certain things in because it depends on the polarity, size,  and type of molecule.

For example, glucose molecules are too large to enter. But, carbon dioxide molecules can go in and out easily because of their small size.

Answer:

This statement is True

“One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.”
