Introduction
This webquest will guide you on a journey through this amazing world of cells, questions, answers and science.
Task
Now that you know the scenario, let's talk about what we are really going to do.
First, this WebQuest will give us a brief review of this fantastic world of cells.
Next, we will learn some facts about how these cells work.
so, let's begin.
Process
-
What do researchers think is one cause of memory impairment related to growing older? What does new research show that may be able to help reverse this process?
new research show that may be able to help reverse this process:
-
Include physical activity in your daily routine. Physical activity increases blood flow to your whole body, including your brain.
-
Stay mentally active.
-
Socialize regularly.
-
Get organized.
-
Sleep well.
-
Eat a healthy diet.
-
Manage chronic conditions.
Three causes of age related memory loss.
-
The hippocampus, a region of the brain involved in the formation and retrieval of memories, often deteriorates with age.
-
Hormones and proteins that protect and repair brain cells and stimulate neural growth also decline with age.
-
Older people often experience decreased blood flow to the brain, which can impair memory and lead to changes in cognitive skills.
-
How might fat cells be able to to help people with spinal cord injuries:
. They could become a source for cell replacement therapy to treat central nervous system disorders in humans.
-
How are frog eggs being used in research involving human cells?
The researchers prepared protein extracts from frog eggs, which recapitulates the repair of the lesion in a test tube. These extracts contain the same proteins that are found in human cells, and therefore represent a good model to study these lesions.
-
What are schwann cells? How are they affected in multiple sclerosis patients?
Schwann cells surrounding neurons protect the degeneration of nerves by blocking thrombin, a blood-clotting protein that can also damage nerves, according to a new study. These findings may aid in the further understanding of genetic and molecular mechanisms behind conditions such as multiple sclerosis.
-
What role do cells play in preventing the stomach from digesting itself?
The stomach does not digest itself because it is lined with epithelial cells, which produce mucus. This forms a barrier between the lining of the stomach and the contents.
Evaluation
With this project we learned how amazing this science world is. How the cells reproduce in order to accomplish their work and help the entire body to heel. It's fantastic how everything in our body works out so our body is good and can function.

Conclusion
summary
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
