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.

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.”

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.

Explanation:

Field independence is a cognitive style that people can manifest, it consists of the ability to isolate a certain trait that is perceived as relevant, from the context in which it is integrated, that is, field-independent people usually isolate the different parts that make up the objects or stimuli. Field-independent people are characterized by having analytical and organizational capacities, a more abstract and impersonal orientation and being autonomous in their social behavior.
