Answer:
The probability her 4th child will be a girl is 0.5
Explanation:
during pregnancy or child birth, the gender of a baby is not affected by the gender of the previous baby in the womb. Rather it is determined by the type of chromosomes supplied by the father of the baby.
If X chromosomes are supplied, a girl will be born because the baby will have xx chromosomes. If Y chromosomes are supplied, the baby will have YY chromosomes which means that he is a boy.
Hence there are equal chances of the baby being a boy or a girl, each time a woman is pregnant. The probability of the baby being a boy or a girl is the same and it 0.5
False, I’m going from what I know but if it’s correct pls heart this
Answer:
C rusting iron
Explanation:
water evaporating and melting is an example of physical change it doesn't change the H2O composition of the atoms, rubbing water on paper doesn't change any atoms or molecules. so the only answer that leaves is rusting iron because when an iron nail comes into contact with water and is then exposed to the air, it rusts, forming a brown-red substance. This process changes the chemical composition of the original substance.
Assuming that the object started in the ground state, any object that has lost one or more electrons would have a positive change because there would be more protons than electrons present. Therefore, the positive charge of the protons would preside over the negative change of the electrons.
Hope this helps.
