The answer is True
Explanation:
A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits.
The factor that determines this is the atomic structure of these two elements which determines how many electrons are found on the outer shell or energy level of these elements.
Ability to form single, double or even multiple covalent bonds is directly dependent on the number of electrons on the outer energy level.
The atomic structure of oxygen 2:8:6 with the outer shell having 6 electrons. Oxygen readily accepts and share 2 more electrons from another element forming two covalent bonds.
Likewise carbon has an atomic structure of 2:4 with 4 electrons in the outer shell. It readily shares these electrons with other elements to form 4 covalent bonds with them.
The value because it could be worth a lot or a little
Explanation:
Answer 1) fertilization takes place in the fallopian tubes, which connect the ovaries to the uterus
Answer 2) sorry i dont know
Answer 3)The unborn baby is connected to the placenta by the umbilical cord. All the necessary nutrition, oxygen, and life support from the mother's blood goes through the placenta and to the baby through blood vessels in the umbilical cord
