C
Which process produces carbohydrates in the leaves, which are then used for the growth of the plant? A) transpiration B) respiration C) photosynthesis D) phototropism
C
Stomata are tiny holes found on the underside of leaves. What tissue are stomata found in, and what is the function of a stomate? A) Stomata are found in the vascular tissue of the leaf, and they form long tubes that allow water to flow throughout the plant. B) Stomata are found in the epidermal tissue of the leaf, and they allow gases to flow in and out of the plant. C) Stomata are found in the ground tissue of the leaf, and it is here that photosynthesis occurs. D) Stomata are found in the meristematic tissue of the leaf, and they reproduce rapidly to allow growth in the search for water and nutrients in the soil.

B
What is the function of the excretory system? A) removal of indigestible feces only B) filtering waste products from the blood C) liberation of energy from food D) dissolving of insoluble foods
B
Consider a cell that has just completed interphase and is about to undergo mitosis. In what order will the cell go through the phases listed below? I: telophase II: prophase III: anaphase IV: metaphase A) II, IV, III, I B) II, I, III, IV C) III, IV, I, II D) I, III, IV, II
A
Which organ system do the kidneys belong to?
Excretory System
Which organ system does the stomach belong to?
Digestive System
Which organ system does the pancreas belong to?
Digestive System or Endocrine System
Which organ system do the lungs belong to?
Respiratory System
Which organ system does the spinal cord belong to?
Nervous System
Which organ system does the heart belong to?
Circulatory System
What is the function of the endoplasmic reticulum?
The ER is a series of tubes that deliver materials to the other organelles
What is the function of the lysosomes?
Lysosomes are the cleaners of the cell. They have enzymes to break down invading bacteria.
What is the function of the ribosomes?
Ribosomes are located on some ER and produce protein.
List two differences between the structure of animal and plant cells.
Two structural differences of animal and plant cells are that plant cells have a cell wall surrounding the cell membrane while animal cells do not and plant cells have a much larger, central vacuole while animal cells have smaller vacuoles.
Cigarette smoke is a carcinogen. This means that cigarette smoke can cause cells to mutate when it comes into contact with them. Describe two differences in cell division between a normal cell and a cell which has a cancer causing mutation.
Two differences between cell division in a normal cell and cancer cell is that cancer cells divide much more rapidly than normal cells and can’t undergo apoptosis (self-destruct).
Describe the “main event” for anaphase.
The mitotic spindle rips apart the sister chromatids from the centromeres and the chromatids move further apart to prepare for telophase.
Describe the “main event” for metaphase.
The sister chromatids line up at the center between the centrioles.
Explain the function of the bronchioles.
Bronchioles are passages for air in the lungs that connect the bronchus to the alveoli.
Explain the function of the diaphragm.
The diaphragm is the large muscle under that lungs that contracts and expands so the lungs can draw in and push out air.
Give an example of two organ systems that interact and explain how they work together.
Many answers. Two organ systems that work together are the respiratory system and the circulatory system. The respiratory system draws in oxygen to supply the circulatory system, which then gives the respiratory system carbon dioxide to expel from the body.
Select one type of medical imaging technology and describe its use in medical imaging.
Many answers. Ultrasound: -it is a imaging technology that sends sound waves through the body and reads the reflected waves to produce an image. -commonly used to get fetus images
