MCB 246 - Reproductive System Day 1 (Exam 4) UPDATED
ACTUAL and Correct Answers
Question: Both females and males have primary reproductive organs called what?
Answer:
Gonads
Question: What are the gonads of females vs males?
Answer:
-females = ovaries
-males = testes
Question: What do the gonads do?
Answer:
produce sex cells called gametes (unite at fertilization to initiate formation
of new individual)
Question: The reproductive system will produce large amounts of sex _____________.
This affects the maturation, development, and activity of reproductive organs.
Answer:
hormones
Question: Both sexes also have ____________ reproductive organs.
Answer:
accessory
Question: What are examples of accessory reproductive organs?
Answer:
-for example, ducts to carry
gametes away from gonads (towards site of fertilization for females and toward outside of body for
males)
Question: When does puberty start and what happens during it?
Answer:
-onset during adolescence
-external sex characteristics develop (for example, breast enlargement in females and for example,
pubic hair
growth)
, -gametes begin to mature
-gonads start to secrete sex hormones = start process of gamete and sexual maturation (female
produces and releases
single gamete monthly; oocyte, male produces 100 million gametes/day, stored for short time only,
reabsorbed if
not expelled from body)
Question: How many pairs of chromosomes are there in human body cells?
Answer:
-23 pairs of
chromosomes
-22 pairs of autosomes and 1 pair of sex chromosomes
Question: Autosomes contain genes that code for cellular functions. These determine
what parts of humans?
Answer:
-determines most human characteristics
-for example, eye and hair color, height, skin pigmentation
Question: A pair of matching autosomes is called what?
Answer:
homologous chromosomes
Question: What are the sex chromosomes?
Answer:
-two X (female)
-one X and one Y (male)
Question: Also, some genes code for other functions, one member of a chromosome
pair inherited from each parent. (______ chromosomes)
Answer:
sex
Question: What is a diploid cell?
Answer:
-23 pairs of chromosomes (46 individual chromosomes)
