Why would bacteria, plant and animal cells need to be different?
Answers
Answer:
Because each the cells would have different functions on different organisms.
Explanation:
Bacteria cells are usually prokaryotic which means that it is only composed of one cell. The single cell already has everything it needs so therefore, it isn't as complex as plant and animal cells.
Plants are autotrophs and produce their own food through photosynthesis. Plant cells would have a large vacuole, cell wall, chloroplasts, unlike animal cells.
Animal cells have all the cell organs that plant cells except a large vacuole, cell wall, and chloroplasts. Animal cells also have lysosomes in which plant cells don't.
What is the difference between the attic and equator Environment
Answers
An attic environment is a hot and muggy place, with few fresh breezes coming in. Meanwhile, the equator is a very dry and low altitude location that has lots of fresh air and major wind currents constantly circulating through. This exchange of air allows for natural temperature regulation- warm air rises to the updrafts at equatorial latitudes and cold air sinks around Antarctica . At a higher latitude like the United States, there are fewer major winds like monsoons or cyclones to provide this necessary "push" for different atmospheric temperatures over time. With little variation in climate (weather) patterns, there is also less need for sweating as moisture evaporation cools down your skin (thermoregulation).
Explanation:
Although we think of land when we hear the word biome, there are also aquatic biomes. The abiotic factors that
influence life forms vary with location within ocean systems. Oceanographers divide the ocean into five broad vertical
zones as seen in the chart above. Compare the characteristics of the five zones. The giant tube worms, Riftia
pachyptila, pictured here, have a red "plume at the tip of their free end which is an organ for exchanging compounds
with the environment. The tube worm does not have many predators. If threatened, the plume may be retracted into
the worm's protective tube. The plume provides essential nutrients to bacteria living inside the worm. Tube worms
have no digestive tract, but the bacteria, which may make up half of a worm's body weight, convert the oxygen,
hydrogen sulfide, carbon dioxide, taken in by the plume, into organic molecules on which their host worms feed.
Compare this information with the information in the chart. Where could these worms live?
A)
The tube worms can only live where there is no light: zones 3, 4, and 5.
B)
C)
Only in the top-most two zones so the bacteria can use the light for
photosynthesis.

How would the loss of predators contribute to deforestation in the
jungle?
Answers
Answer:
Predators eat prey. When they do so, they are keeping the population or number of prey in check. Now, a lot of prey are either herbivores or omnivore, meaning plants are in their diet. If there were to be no predators, an absurd overpopulation of prey would arise. This would cripple the growth of young trees by the prey feeding on them, and overall would over-run their habitat, making the food sources scarce. When the food source gets so low they will die out or continue to move on to other surrounding areas and create the same problems.

4. Estimate the size of the outlined (yellow) onion cell under high power (40x). Use the dFOV values calculated from question no. 3. 10 points
Answers
The following formula is useful to determine the size of the cell ⇒ Size of the object = FOV / Fit number = dFOV / Fit number. If you have this data, you can estimate the size of the onion cell. According to the values we used, the estimated size of this onion cell is 112 μm.
-----------------------------------------------
Cells are too small to measure their sizes, so to know their actual size, we can make mathematical estimations to know their sizes, or we can use software programs. In this case, we are estimating their size using the following formula,
Size of the object = FOV / Fit number = dFOV / Fit number
Size of the object = size of the cellFOV = eyepiece (mm)/objective magnification Fit number = The number of times the object -cell- fits in the field of viewTo answer this question, we will replace the terms in the given formula.
→ First, we will get the FOV value. From references, we can assume that
under 4X ⇒ FOV = 4.5 mmunder 10X ⇒ FOV = 1.8 mmunder 40X ⇒ FOV = 0.45 mmYou can also calculate the FOV by using a millimeter paper or rule.
Note: We will use these values to replace terms in the formula, but you can use the dFOV value calculated in question no. 3.
→ Second, we will count the number of cells that fit the field. We can see about four cells across the field of view.
→ Finally, we will replace the terms in the formula.
Size of the object = FOV / Fit number
Size of the object = 0.45 mm / 4
Size of the object = 0.112 mm
Since we generally use μm when referring to cell sizes, we need to multiply 0.112 x 1000 to get the size of the cell expressed in μm.
Size of the cell (μm) = 0.112 mm x 1000 = 112 μm

For multicellular organisms, division is necessary for growth and renewal. Even though cell division is natural and necessary, what happens when the rate of cell division becomes too rapid and out of control? How can we get rid of such rapidly dividing cells in the human body?
Answers
Answer:
Here are 5 important things you should know about cancer cells:
1. Everyone has cancer cells in their body. These cells are not detected in routine tests until they have multiplied and grown to billions of cells.
2. Cancer cells are present in the body about 6-10 times in a person's lifetime.
3. When the immune system is healthy, cancer cells will be destroyed, preventing tumor growth and formation.
4. When a person has cancer, it means that he or she may be suffering from severe nutritional deficiencies or due to toxic environmental factors, unhealthy lifestyles and diets.
5. An effective way to fight cancer is to starve cancer cells by not providing them with the food they need to proliferate and grow.
"3 golden rules" help kill cancer cells:
1. Diet to prevent cancer
It can be said with certainty that there is no better way to keep your immune system healthy than with a reasonable and scientific diet. So ask yourself the question "Do you really have a reasonable diet to prevent cancer?". And here are the essential suggestions.
- Increase your diet with fresh vegetables, fruits, whole grains and foods high in fiber.
Eat more antioxidant foods: The fruits below are rich in antioxidants.
In addition, all vegetables and fruits contain a lot of vitamin A (carrot, papaya, tomato, sweet potato, pumpkin), vitamin C (orange, cherry, kiwi, strawberry), vitamin E (avocado, papaya). , cashews, peanuts, sunflower seeds, almonds...) are also foods with strong antioxidant capacity to help prevent cancer.
- Increase vitamin D supplementation.
Vitamin D is a special vitamin that is more important than all other vitamins because of its "universal" effect on the body's immune system. Its biological effects are related to the expression of more than 3000 genes in the body.
In addition to the extremely important role for the musculoskeletal system, the role of vitamin D in the prevention of many cancers and infectious diseases has been scientifically proven.
More than 90% of vitamin D in the body is synthesized in the skin under sunlight. Very little is absorbed from the diet, so the daily diet cannot guarantee the full amount of vitamin D needed by the body.
A recent study by a joint research team between the 108 Central Military Hospital and the University of Tuebingen (Germany) published in the journal BMC Infectious diseases showed that about 90% of healthy people are deficient in this vitamin. plasma vitamin D concentration <30 ng/ml).
Research also shows that there is a strong association between vitamin D deficiency and liver cancer in patients infected with hepatitis B. So the simplest way to ensure that you do not have a deficiency is to take vitamin D supplements. daily dose of 10-20 (µg/day) for all ages.
- Do not eat a lot of sugar and sweets because this is a food source that helps tumor growth. Sugar, not protein, is what tumors need to grow, so people with cancer still need the protein found in meat to boost their health against cancer. However, it should be noted that you should not eat a lot of red meat but should eat chicken and fish instead of beef and pork.
2. Increase physical activity
This is the most important principle of strengthening the immune system that anyone can do. The largest study conducted by the National Cancer Institute (USA) on more than 1.4 million people found that regular physical activity reduces the risk of 13 common types of cancer in humans.
The link between physical activity and reduced risk of many types of cancer can be explained by several key mechanisms:
- Strengthen the immune system, prevent the growth and spread of infectious agents.
- Physical activities help increase metabolism, improve circulation and help transport oxygen to all organs. Cancer cells must not grow in an oxygen-rich environment because oxygen can kill cancer cells.
Lowering levels of hormones such as insulin, estrogen and growth factors are thought to be closely related to cancer formation and development.
- Control weight, prevent obesity: Obesity is a leading risk factor for many types of cancer, metabolic disorders, cardiovascular diseases... It is estimated that more than 500,000 cancers are diagnosed each year. obesity-related diagnoses.
Increased blood flow to organs such as the liver, kidneys and intestines enhances the efficient elimination of waste products and toxins that can be potential causes of cancer from the body.
