What Do You Know About Pregnancies?

Explanation
Gestation is the correct answer because it refers to the period of development of an embryo or fetus inside the uterus of a female mammal. It is commonly used to describe the duration of pregnancy in humans and other animals. The term "pregnancy" is often used interchangeably with "gestation" to describe the state of carrying a developing offspring in the womb.

Explanation
Coitus is the correct answer because it refers to sexual intercourse between a male and a female, where the penis is inserted into the vagina. This is the most common way for pregnancy to occur as it allows for the sperm to fertilize the egg. Kissing, touching, and felatio do not typically lead to pregnancy as they do not involve the direct transfer of sperm to the vagina.

Explanation
A pregnancy test can be used to confirm pregnancy. This is a common and reliable method that detects the presence of human chorionic gonadotropin (hCG) hormone in a woman's urine or blood. The hormone is produced by the placenta after implantation occurs. Protruding stomach is not a definitive sign of pregnancy as it can be caused by other factors such as weight gain or digestive issues. Coitus, which refers to sexual intercourse, is the act that may lead to pregnancy but it cannot confirm it. Therefore, the correct answer is pregnancy test.

Explanation
During the first 8 weeks of development, the developing offspring is referred to as an embryo. At this stage, the embryo undergoes rapid cell division and starts to develop basic structures and organs. After the first 8 weeks, it is then called a fetus. The term "offspring" refers to any young organism, while "toddler" is a term used to describe a young child who has just started walking.

Explanation
After 8 weeks of development, the name given to the developing offspring is "foetus". At this stage, the major organ systems have formed and the foetus begins to resemble a human. It is during this period that the foetus undergoes rapid growth and development, with the formation of distinct features such as limbs, facial features, and internal organs. The term "foetus" is used to describe the stage of development from 8 weeks until birth.

Explanation
Fertilization is the process in which a sperm cell fuses with an egg cell, resulting in the formation of a zygote. This is the initial step in sexual reproduction and the beginning of the development of a new organism. Coitus refers to sexual intercourse, which is one way in which fertilization can occur, but it is not the only method. Therefore, the correct answer is "Fertilization" as it encompasses the concept of sperm fertilizing the egg, regardless of the specific method of conception.

Explanation
Gravida is the correct answer because it is a medical term used to refer to a pregnant female. It is derived from the Latin word "gravidus" which means pregnant. This term is commonly used in obstetrics to describe the number of times a woman has been pregnant, regardless of the outcome of those pregnancies.

Explanation
Gravidity is the correct term used to describe the number of times that a female has been pregnant. It does not refer to the outcome of the pregnancies (whether they resulted in live births or not), but simply counts the number of times a woman has been pregnant. The term "pregnancity" does not exist, and "gravicle" is not a recognized medical term. Therefore, the correct answer is Gravidity.

Explanation
Pregnancy is typically broken into three periods. This is because pregnancy is divided into trimesters, with each trimester representing a distinct stage of fetal development. The first trimester is from week 1 to week 12, the second trimester is from week 13 to week 28, and the third trimester is from week 29 until delivery. These periods help healthcare providers monitor the progress of the pregnancy and ensure the well-being of both the mother and the baby.

Explanation
Childbirth is the correct answer because it refers to the process by which an infant is born. It involves the delivery of a baby from the mother's uterus through the birth canal. Childbirth typically occurs after a gestation period of around nine months and is a natural process that can be assisted by medical professionals if necessary. The term "toddler birth" is not a recognized term and does not accurately describe the process of an infant being born. Therefore, the correct answer is childbirth.
