what do the arguments for and against the use of stem cells in medical research share?
Answer: Stem cell research can potentially help treat a range of medical problems. It could lead humanity closer to better treatment and possibly cure a number of diseases:
Parkinson’s Disease
Alzheimer’s Disease
Heart Diseases, Stroke and Diabetes (Type 1)
Birth Defects
Spinal Cord Injuries
Replace or Repair Damaged Organs
Reduced Risk of Transplantation (You could possibly get a copy of your own heart in a heart-transplantation in the future
Stem cells may play a major role in cancer
Better treatment of these diseases could also give significant social benefits for individuals and economic gains for society
Cons
"We should not mess with human life."
"Humans should not be trying to play God"
Some argue that stem cell research in the far future can lead to knowledge on how to clone humans. It is hard to say whether this is true, but we have seen devastating consequences of other research-programs, even with good intentions, such as nuclear research.
Stem cells are cells, which have the ability to transform into many different types of cells. The stems cells have the potential to specialize in any type.
The stem cells are extensively used for research, curing diseases, and especially in developing prosthetics. The stems cells provide new cells for the growth and development of the replaced and damaged cells.
The arguments for and against the use of stem cells are:
Arguments for the use of stem cells in medical research are:
1. The stem cells enhance the growth and development of healthy skin tissue.
2. The cells can be used to enhance the production of collagen.
3. The study of stem cells helps in understanding the causes of disease.
Arguments against the use of stem cells in medical research are:
1. The use of stem cells for research harms human life and dignity.
2. People believe that killing blastocysts or stem cells is equal to taking a human life.
3. However, the transplant of stem cells can be rejected by the patient's body, therefore, can cost the life of the patient.
Therefore, the use of stem cells for research can be fruitful or disadvantageous.

Earth follows an orbit as it makes a revolution around the Sun. What is the relationship between a revolution and an orbit?
Answer:
An orbit is essentially the motion of an object (be it a planet, a moon, a spacecraft) around a star, moon, or planet. Now a revolution is the movement of an object around an axis of rotation, or a centre, or another object. So the earth revolves around the sun, but the earth is also in orbit around the sun.

Explain how a. temperature and b. light intensity 0 affect the rate of transpiration.
Answer:
Explanation:
Transpiration can be regarded as process involving water movement through a plant, it involves evaporation from aerial parts. These aerial part could be such leaves, stems or flowers.
A)Temperature
During the day period when the weather is hot there would be increase in evaporation of water from the leaves of plants, due to this transpiration is increased
B)Light intensity
When there is bright light, when the light intensity heat the plants, the stomata would be opened so that carbon dioxide is supplied for photosynthesis, and more water would be evaporated out through the leaves of the plant, then transpiration increase

Explanation:
Men are expected to do work that women cannot do. For example going outside and earning money or take decisions that effect the family. These are the thoughts of society and are mostly implemented in households.
Being masculine means that men comparatively have a strong physical ability than women. They can do heavy duty works with ease
Women are expected to sit in the house. According to society women are naive and need to be under the protection of man. Women are expected to be good mothers and obedient wives. They should be able to run the house well.
Being feminine means that women is very delicate and sensitive like a flower. A man has to nourish her and take care of her while the woman will become a beautiful flowers and fill the house with a strong fragrance.
Apart from these men and women are free to do what ever they want because in the 21st century not a lot of these old gender roles are followed. Sometimes the roles get swapped and women work outside just because they want to or because of the economic conditions.

Why are stabilizing proteins neeed to keep the DNA strands separated?
Single-stranded DNA-binding proteins are protected exactly tightly to DNA, but with extremely little carefulness for individual nucleotide sequences.
What is DNA?
They accomplish this by interacting strongly with the DNA backbone, via hydrogen bonds with the ribose and phosphates and complementary control interactions with the phosphates.
When the Proteins of DNA Replication DNA Helicases. These proteins attach to the double-stranded DNA and facilitate the separation of the two strands. DNA single-stranded critical proteins.
Although, These proteins bind to the DNA as a stable tetramer the single-stranded structure is produced by the action of the helicases.
Single-stranded DNA-binding proteins (e.g., [RFA] eukaryotic replication factor A) then stabilize the decompressed template DNA, maintaining it in an extended single-stranded state so that it can be simulated by the polymerase.

the connection between limiting factors and invasive species
Answer:
Biology, Ecology, Earth Science, Climatology, Geography
Explanation:
A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor. Likewise, if there is not enough space in a pond for a large number of fish, then space becomes a limiting factor. There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support

Explanation:
3. Explain the role of organisms in the carbon
cycle and oxygen cycle
What organism? If its plants, they give oxygen during the day and carbon dioxide in the night. While animals give carbon dioxide but take oxygen from the air. These carbon dioxide gas and oxygen gas go to the atmosphere and affect the carbon cycle and oxygen cycle.
Here is the cycle if you want to know more
Plants (give out oxygen) -> Animals (Use oxygen) + (given our carbon dioxide) -> plants (take oxygen)
and so on
Answer:
Plants take carbon from the atmosphere in the form of carbon dioxide during photosynthesis. Plants and animals both release carbon dioxide back into the atmosphere through the process of respiration. When organisms die, some of the carbon in their bodies is stored in the soil, which can be reintroduced into the atmosphere through soil respiration.

2. A lunar eclipse can occur when the Moon is in......in its orbit.
Help me this is from amplify
Answer:
Lunar eclipses can only happen when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon. But lunar eclipses do not occur every month because the Moon's orbit is tilted five degrees from Earth's orbit around the Sun. Without the tilt, lunar eclipses would occur every month.
A lunar eclipse occurs when the moon moves into the earth's shadow, it occurs when the earth, moon, and sun are close together.
What is a lunar eclipse?When the Moon passes through the shadow of the Earth, a lunar eclipse happens and also depends on the sun.
Only on the night of a full moon when the Moon is close to either lunar node can the Sun, Earth, and Moon be precisely or extremely closely aligned with Earth between the other two.
When the Moon and Sun are on opposing sides of Earth, a total lunar eclipse takes place. When only a portion of the Moon is covered by Earth's shadow, a partial lunar eclipse occurs.
Therefore when the moon moves into the earth's shadow lunar eclipse happens.
