Answer:
Sperm washing is the process in which individual sperms are separated from the semen. Washed sperm is used in artificial insemination using the intrauterine insemination (IUI) technique and in in vitro fertilization (IVF). It may also be used to decrease the risk of HIV transmission by an HIV-positive male, in which case the washed sperm is injected into a female using an artificial insemination technique.
Sperm washing involves removing any mucus and non-motile sperm in the semen to improve the chances of fertilization and to extract certain disease-carrying material in the semen. Sperm washing is a standard procedure in infertility treatment.
Explanation:
Sperm washing takes place in a laboratory following sperm donation.
Sperm may be washed by density gradient centrifugation or by a "direct swim-up" technique that does not involve centrifugation. In normal semen samples, centrifugation causes no more DNA damage to spermatozoa than a direct swim-up technique.[1]
Washed sperm is concentrated in Hams F10 media without L-glutamine, warmed to 37 °C (99 °F).[2] A chemical known as a cryoprotectant is added to the sperm to aid the freezing and thawing process.[3] Further chemicals may be added which separate the most active sperm in the sample, as well as extend or dilute the sample so that vials for a number of inseminations are produced.

Eat foods that are easily digestible and high in fiber
Answer:
C. A Catholic woman who fasts on Good Friday to honor religious custom.
Explanation:
Today, many people carefully consider what they eat before consuming it according to his or her values, in contrast to choosing what to eat only by cravings or 'superficial' decisions. For example, choosing to consume less meat due to the impacts that the meat industry has in our climate is a decision someone makes in regard to values, not only nutrition. So, there is much more analysis involved in this type of decisions.
In this scenario, a Catholic woman decides to fast on Good Friday because she is honoring her religion. This is not a nutrition or health choice, this is a conscious decision based on her values. On the other hand, the other options refer to decisions they make in regard to taste, cravings, or diet.
