I’m not sure if it’s all completely right but i’m pretty sure it is
Stairs are an example of an incline plane.
Griffith experiment
Griffith used two types of bacteria in his experiment
1. R-type: it was non-virulent and cause no disease in mice
2. S-type: It was virulent and cause disease in mice which lead to death.
However when heat killed S-type was applied no disease was occurred in mice. Then he mixed heat killed S-type and live R-type and injected it into mice. He was expecting that no disease will be caused in mice.
Results
However, mice was died.
Conclusion
He was confused from this experiment. But later it was confirmed by other scientists that DNA from heat killed S-type was shifted to R-type. the progeny which formed from this transfer of DNA were virulent and cause the death of mice.
significance
It was concluded from this experiment that DNA is a hereditary material which transfer characters from parents to offspring.
Conventional in vitro fertilization refers to the development of embryos in the laboratory conditions, intracytoplasmic sperm injection refers to the add of sperm cytoplasm to the egg cell, laser-assisted hatching helps the egg cell to reach the zona pellucida while artificial insemination helps to development of a zygote by artificial fertilization.
<h3>What does assisted reproductive technology mean?</h3>
The medical term assisted reproductive technology makes reference to all methods and strategies aimed at enhancing or helping the development of the zygote or embryo after fertilization, which may be in vitro fertilization (laboratory conditions) or in vivo conditions into the reproductive system.
Therefore, with this data, we can see that assisted reproductive technologies refer to a broad differential category of strategies and methods aimed at helping with the development of zygotes and embryos in the reproductive system of a woman or in the lab conditions.

When the sperm enters the female, the chemicals from the pill kill the sperm. Therefore the female won’t get pregnant.
I hope this helps.
