Spontaneous miscarriage in the first trimester is related to Chromosomal defects in the fetus. An estimated 15 to 20 percent of known pregnancies end in miscarriage, the loss of a pregnancy before the 20th week. Upto 70 percent of first-trimester miscarriages, and 20 percent of second-trimester miscarriages, are caused by chromosomal anomalies/abnormalities in the fertilized egg. Most often, it means that the egg or sperm had wrong number of chromosomes, and consequently the fertilized egg can't develop normally.
Draw a box. On the vertical side of the box write A and O
On the horizontal side write B and O
Take each letter and combine it with the two letters in the other plane and write them in the box.
AB AO OB OO and BA BO OA OO
Knowing that the A and B genes are dominant … you get the following children probabilities:
AO OA are A’s
OB BO are B’s
AB BA are AB’s
OO and OO are O’s
THE TWO PARENTS CAN PRODUCE all the blood types of the ABO SYSTEM.
<u>Answer:</u> The correct answer is the dependent variable changes in response to changes in the independent variable.
<u>Explanation:</u>
Dependent variable is defined as the variable which varies in accordance to the change in independent variable. For Example: Current is a dependent variable and voltage is the independent variable according to Ohm's law.
I ∝ V
Independent variable is defined as the variable which does not change in accordance to any other variable in a given scientific experiment. For Example: Time (as expressed in seconds)
Hence, the correct answer is the dependent variable changes in response to changes in the independent variable.
