Answer:
Genetic testings is very ethical in a sense that it helps determine the DNA of a child.
Explanation:
Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder. This means that a family can find out whether their child has autism before it is even born, or discover a potential mutation it might have. It is a cautious procedure but inhabits the well being of a child.
Explanation:
There are eight major terrestrial biomes: tropical rainforests, savannas, subtropical deserts, chaparral, temperate grasslands, temperate forests, boreal forests, and Arctic tundra. Biomes are large-scale environments that are distinguished by characteristic temperature ranges and amounts of precipitation. These two variables affect the types of vegetation and animal life that can exist in those areas. Because each biome is defined by climate, the same biome can occur in geographically distinct areas with similar climates .
Answer: The genotype of a female is XX while that of a male is XY. The probability of them having a male child is 1/2 while the probability of having a female child is 1/2.
Explanation: Normally, females have two X chromosomes (XX) while males have one X chromosome and one Y chromosome (XY). In a cross between a man and a woman, there is fifty percent chances of having a female child and also fifty percent chances of having a male child. Therefore, the probability of having a female child is 1/2 while the probability of having a male child is also 1/2.

1 st question ) Lack of food and oxygen and the presence of wastes limit their growth.
Basically structure of DNA is very important in the process of replication.
DNA molecules have antiparallel structure i.e. the two strands of the halix run in opposite directions of one another. Each strand has 5 prime end and 3 prime end. Solving the structure of DNA unlocked the door to understanding many of the function of DNA, such as how it copied and how the information it carries can be used to produce protein.
