Unlike Earth, Mars has lost their atmosphere over time, causing it to become harsh and uninhabitable. What has protected the Earth's atmosphere?

Answer:

The energy of the sun is the original source of most of the energy found on earth.

I hope this helps you!

Answer:

The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photo-voltaic) cells. The sun heats the earth's surface and the Earth heats the air above it, causing wind.

Answer:

A monomer is a type of molecule that has the ability to chemically bond with other molecules in a long chain; a polymer is a chain of an unspecified number of monomers. Essentially, monomers are the building blocks of polymers, which are more complex type of molecules.

Answer:

A scientific question is one where an investigation can be designed and completed to find out the answer without having to do multiple, entirely different investigations to get there. In a word, a scientific question is testable, but a non scientific question is not.

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.”

Answer:

Why does air on Earth not move simply in a direct path between the equator and the poles? Air does not move in direct paths because of the Coriolis effect. ... Air is deflected toward the southwest in the Northern Hemisphere and toward the northwest in the Southern Hemisphere.

Explanation:

Answer:

The cell membrane can be compared to the school gates.

Explanation:

Cell membranes only let in specific molecules (people), large substances (old people) cannot cross it while smaller molecules like oxygen (students) can easily pass through the membrane.

Explanation:

Answer:

An increase in temperature.

Explanation:

When the temperature rises water evaporates much quicker than if it were just a lightsource hitting the surface of the water. It's like if where really hot outside and you had a pool.The water would start to steam up and evaporate has the temperature rose.

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:

Answer:

If a rubber band is narrow, then it will stretch more because it resists less.

Explanation:

No .because virus is molecule.

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.

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.

Based on the given information,

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.
