Trilateration Measures Distance, Not Angles
Using a simple two-dimensional example, let's imagine we have three GPS satellites each with a known position in space. ... This means that the distance could be anywhere on that circle. But this time, we have two known distances from two satellites.
Answer: In vitro fertilization
Explanation:
In vitro fertilization (IVF) involves some procedures used to help with fertility. This series of procedures are usually complex and can help prevent genetic problems and assist with the conception of a child.
During IVF, mature eggs are collected from the female ovaries and sperms from the male and fertilized in the laboratory. The fertilized egg are then transfered back into the uterus for its growth and development.
The sperm and eggs could be from partners who have decided to carry out IVF or from donors. IVF is usually Carried out by high rating laboratory. One full cycle of IVF takes about three weeks. IVF are usually expensive and could take a longer time if splits into different aspects.
IVF is an effective reproductive technology.
Answer:
Genes coding for proteins involved in chiasma formation.
Explanation:
Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.
Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.
Answer: Biological Test Biological tests are frequently used to validate the physical and chemical tools or to provide complementary evidence about bioavailability process in a system. From: Chemosphere, 2017

Yw and pls mark ME AS THE BRIANIEST :D
I have done GCSE sciences and also applied science a level so I could probably help you :)
