TEAS version 7 quizlet science
1. Which element is used in fertilizers due to its role in plant cell division and growth?
- A. Potassium
- B. Phosphorus
- C. Calcium
- D. Magnesium
Correct answer: B
Rationale: Phosphorus is the correct answer. It is used in fertilizers due to its essential role in plant cell division and growth. Phosphorus is a key component of nucleic acids, such as DNA and RNA, which are essential for cell division and growth in plants. Potassium (Choice A) is important for overall plant health and functions like enzyme activation, but it is not specifically known for its role in cell division and growth. Calcium (Choice C) is crucial for cell wall structure and stability but not primarily for cell division. Magnesium (Choice D) is essential for chlorophyll production and photosynthesis, but it is not directly linked to plant cell division and growth.
2. Where is the cervix located?
- A. Top of the uterus
- B. Top of the ovaries
- C. Bottom of the vagina
- D. Bottom of the uterus
Correct answer: D
Rationale: The cervix is located at the bottom of the uterus, where it opens into the vagina. It serves as the passageway between the uterus and the vagina, playing a crucial role in childbirth and menstrual flow. Choice A ('Top of the uterus') is incorrect because the cervix is not located at the top of the uterus. Choice B ('Top of the ovaries') is incorrect as the cervix is not located near the ovaries. Choice C ('Bottom of the vagina') is incorrect as the cervix is not located at the bottom of the vagina, but rather at the bottom of the uterus.
3. What is the muscular sac in the female body that nourishes and protects a developing fetus during pregnancy?
- A. Ovary
- B. Fallopian tube
- C. Uterus
- D. Vagina
Correct answer: C
Rationale: The correct answer is the uterus. The uterus is a muscular organ in the female body where a developing fetus is nourished and protected during pregnancy. It is the site where a fertilized egg implants and grows into a fetus. The ovaries produce eggs, the fallopian tubes transport the egg to the uterus for potential fertilization, and the vagina serves as the birth canal and the passage for menstrual blood to exit the body. Therefore, the uterus plays a crucial role in pregnancy by providing a nurturing environment for the developing fetus.
4. What is surgically altered during a vasectomy?
- A. Vas deferens
- B. Glans penis
- C. Prostate
- D. Urethra
Correct answer: A
Rationale: During a vasectomy, the vas deferens is surgically altered or cut to prevent the transport of sperm from the testicles to the urethra. This procedure is a form of permanent male sterilization. The glans penis, prostate, and urethra are not surgically altered during a vasectomy. Therefore, the correct answer is the vas deferens (Choice A), as it is the structure specifically targeted and modified in this procedure. The glans penis (Choice B) is the sensitive tip of the penis, the prostate (Choice C) is a gland vital for semen production but not involved in a vasectomy, and the urethra (Choice D) is the tube that carries urine and semen but is not surgically altered in a vasectomy.
5. Which organ is responsible for filtering blood and removing waste products?
- A. Liver
- B. Kidneys
- C. Spleen
- D. Pancreas
Correct answer: B
Rationale: The correct answer is the kidneys. The kidneys filter blood and remove waste products through the formation of urine. The liver primarily functions in detoxification and metabolism. The spleen is involved in blood filtering and immune function. The pancreas produces digestive enzymes and insulin, not involved in filtering blood.
