How does photosynthesis take place? need detailed explanation
Answer:
Photosynthesis takes place inside plant cells in small objects called chloroplasts. During photosynthesis, Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Light energy comes from the Sun. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Cells are capable of reproducing themselves by cell division. For single celled organisms, cell division is essentially reproduction. 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?
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.

Compare a virus to a unicellular organism. (1 point)
O Viruses need energy, unicellular organisms do not need energy.
O Unicellular organisms have a cell membrane made from a lipid bilayer, viruses have a protein coat
O Viruses reproduce through asexual reproduction; unicellular organisms need a host cell,
O Neither unicellular organisms nor viruses respond to stimuli.
Answer:
differences : Viruses need energy while unicellular organisms donot need energy
Unicellular organism has cell membrane but virus has protein coat.
Unicellular organisms have a cell membrane that is made from a lipid bilayer whereas viruses have a protein coat which is called capsid. Unicellular organisms reproduce through asexual reproduction whereas virus need a host cell for their survival because virus use the cell engine to extract food for their survival so it is conclude that unicellular organisms have cell membrane but virus has protein coat.

WHAT IS HOMESTASIS???? SOMETHING I CAN UNDERSTAND PLEASE!
Explanation:
Homeostasis, from the Greek words for "same" and "steady," refers to any process that living things use to actively maintain fairly stable conditions necessary for survival. The term was coined in 1930 by the physician Walter Cannon.
Examples include thermoregulation, blood glucose regulation, baroreflex in blood pressure, calcium homeostasis, potassium homeostasis, and osmoregulation.
PROCESS OF HOMEOSTASIS IN THE HUMAN BODY
Homeostasis refers to the body's ability to maintain a stable internal environment (regulating hormones, body temp., water balance, etc.). ... As the body works to maintain homeostasis, any significant deviation from the normal range will be resisted and homeostasis restored through a process called a feedback loop.
Answer:
Hi there :)
Explanation:
HOMEOSTASIS
A property of cells, tissues, and organisms that allows the maintenance and regulation of the stability and constancy needed to function properly.
- In simple terms, Homeostasis is any self-regulating process by which an organism tends to maintain stability while adjusting to conditions that are best for its survival. If homeostasis is successful, life continues; if it's unsuccessful, it results in a disaster or death of the organism.
Hope it helps :)

HELPP!! (40 pts) Explain how the earth's core has impacted human life. Use evidence from the
text to support your answer.
Answer:
The earth’s core affects the shape of the ground we
walk on.
Explanation: The earth’s core is responsible for
not only the Rocky Mountains, but the formation of cities and societies that have lived there for
generations, such as Rocky Mountain National Park. It’s responsible for mountains that serve as barriers,
bringing to life divisions in culture unique to each side, while also posing a challenge to be crossed and
burrowed into, spurring on scientific innovation in the process.
The Earth's core has impacted human life in a variety of ways. As it is responsible for the generation of the earth's magnetic field and contains a history of the planet.
What do you mean by the Earth's core?The Earth's core may be defined as the innermost layer of the Earth which is very hot and dense.
The Earth's core is responsible for any geographical locations like mountains, deserts, biodiversity hotspots, rivers, etc. It gives a structural appearance to the Earth. Human life is widely impacted and depends on all of these locations for their needs. All these geographical locations determine the climate of that particular area which is responsible for those people who are living at that location. Human life takes all its requirements from this core surface only.
Therefore, the Earth's core has impacted human life in a variety of ways. As it is responsible for the generation of the earth's magnetic field and contains a history of the planet.
