How do active and passive transport differ? is osmosis active or passive

Answers

Answer 1

Answer: Well, the cell membrane is full of a bunch of little holes. Sort of like a coffee filter.

What does a coffee filter do? Well, you put the coffee in it and run water through it. Then what?

The water is small enough to pass through the filter and bring some of the coffee with it. But the coffee grains are too big to pass through the filter. If we really wanted the coffee grains to get through the filter, we could force them through. Do you want chunks in your coffee? Eww.

Now the cell membrane is the same way, the little things (water, carbon dioxide, oxygen, sugar) are all small enough to fit through the tiny holes in the cell membrane. This is called, "Passive Transport". Because the things can passively float their way in and out of the cell.

Now some other things are too big to fit through, so to make them fit, the cell has to use energy to open itself a little bit more to let them in. This is called, "Active Transport". Because the cell needs to be active and use energy to let those things in.

Now Osmosis is the transfer of water and salts (basically) throughout the cell.
Both Salt and Water are small enough to fit through the Cell Membrane using "Passive Transport".

I've posted this same response earlier, and it is my writing.

Answer 2

Answer:

Answer: Passive Transport - Taking the Easy Road. While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules. It could be as simple as molecules moving freely such as osmosis or diffusion.

What's a question that could be answered by observing chromosomes of different species of animals

Answers

Answer:

we can ask questions related to karyotype, such as: how many chromosomes a certain species have? known as chromosome count, how large are the chromosomes of one species compared to another? what are the taxonomic relationships between some species?

Explanation:

when we observe chromosomes, we´re describing the karyotype, which varies among different species, the study of the karyotype is known as karyology, and thought some techniques such as stainings, can provide information such as number of chromosomes, positioning of centromeres, differences in size or distribution of heterochromatic region, taxonomic relationships, among other. in humans, there are 46 chromosomes, and we can see for example the sex chromosomes, and determine the sex and other physical characteristics

1. what clue to the presence of certain genetic disorders can be seen in karyotype? 2. why might a lab worker attempting to diagnose a genetic disorder prefer to work with photographs of chromosomes rather than the chromosome themselves? 3.why would it be much difficult to construct a karyotype of unstained chromosomes?

If you feel pain during weight training, what should you do?Move more quicklyMove more slowlyIncrease weightStop altogether

Answers

If you feel pain, moving faster, adding more weight, or even moving slower could end up in feeling more pain. The best thing to do is just plainly to stop altogether and get some rest. Pain is supposed to tell you something is wrong with your body when you do a certain exercise.

Answer: Option (d) is the correct answer.

Explanation:

When we do weight training then our muscles start to work even harder as compared to the work that they normally do.

So, it is required to initially start weight training with less weight but if you feel the pain during weight lifting then it is advisable to stop altogether. This is because continuing the weight training might lead to serious muscle injury.

So, it is better to stop the training and continue only when the pain is relieved.

Thus, we can conclude that if you feel pain during weight training, then you should stop altogether.
