Dan and Fiona have decided to utilize technology to overcome their infertility problems. They opt for a procedure in which a mature ovum is surgically removed, fertilized in a laboratory dish, and then implanted in the woman's uterus. This technique is called:

This technique is called in-vitro fertilization.

Explanation:

In-vitro fertilization (IVF) refers to a form of assisted-reproduction technology in which the encounter of male and female gametes takes place outside the female organism (such as a human patient, in this case). IVF may be employed in several situations, including:

- Abnormalities in the female reproductive tract which impair the flow of the ovum into the uterine cavity (e.g. blocked fallopian tubes).

- Abnormally low sperm counts.

- Surrogate pregnancy.

the answer is: they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur twice a year in the spring and fall.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
