Please help Explain how independent and dependent variables apply to life

Biology
1 answer:
Crazy boy [7]2 years ago
4 0

Answer:

If one wants to estimate the cost of living of an individual, then the factors such as salary, age, marital status, etc. are independent variables, while the cost of living of a person is highly dependent on such factors. Therefore, they are designated as the dependent variable.

Imagine that y-axis of each graph describes the rate of photosynthesis. Which of the graphs represents the
astraxan [27]

Answer:

a. <u>A</u><u> describes the effect of light intensity on photosynthesis.</u>

Explanation:

In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.

The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:

  • carbon dioxide concentration,
  • ambient temperature
  • and light intensity

It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as <u><em>the intensity increases steadily, so does the rate</em></u>- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.

Beyond this point, either the supply of <em>carbon dioxide or the temperature</em> limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.

20. How did HeLa cells make it possible to diagnose trisomies like Down syndrome?
Rasek [7]

He La cells have play important role in the study of cancer and even in cancer therapies. He La cells are also used to diagnose trisomic disorders such as Down's Syndrome with the help of chromosome banding. Some genes present in the He La cells are used as markers and compared with the other cell line in question. Presence of the marker for Down's syndrome in the cell in question shows that the person is suffering from the disease.

30 POINTS HELP ASAP! WRITE IN YOUR OWN WORDS!!! I WILL MARK BRAINLIEST HELP PLEASE ITS DUE TODAY AND I REALLY NEED TO GET IT DON
Elis [28]

Answer:

Stem cells are cells in the human body that have the ability to develop into many other body cell types. Stem cells are very useful for drug development, research, they aren't likely to be rejected in transplants, and are used to repair damaged or diseased cells and tissues. However, they cannot be grown for long periods of time, there are very small numbers in each tissue and cell making them very hard to find, and for certain studies they have been shown to cause cancer. To be honest, using them in research does have its pros and cons, they are very useful and easier to use in research, plus they can help repair damaged and diseased cell tissues. But at the same time they can be difficult to use correctly and properly, it can cause serious health problems if cancer doesn't take place. I think that using them in research is okay, as long as they are used correctly and properly.

Hope this helps! :)

What do we mean when we say that the resulting ADP molecule is recycled?
LenaWriter [7]
  • ATP A ADP + P + energy here's what it looks like chemically, Each phosphate is a Po4( oxygen has a charge of -2 and there are 4 of them, for a total of - 8 and P has a charge of +5, so the net charge of the phosphate group is -3 if free H atom, which are +1, get added to the 0 atoms that aren't bonded to two things then the net charge is zero.)
