Total questions: 17
Worksheet time: 11mins
The organization of the human body includes both nervous tissue and muscle tissue. What do both nervous tissue and muscle tissue have in common?
Each tissue is found in only one organ in an organism
They both are found in the samae organ inside an organism
Each tissue is made of groups of similar cells that work together
They are organized into organ systems that help an organism live
The survival of a cell depends on the cell maintaining homeostasis. What is most likely to happen to a cell if homeostasis is not maintained?
The cell will immediately divide
cell processes will continue unchanged
the cell will eliminate wastes more efficiently
Many chemical reactions in the cell will slow down or even stop.
Cells can die or become damaged. Which part of cell theory is used to replace dead or damaged cells?
Cells divide to make new cells
cells multiply by cellular respiration
cells take in new cells through endocytosis
cells grow larger to make up for the lost cells
Pedro examines a tissue under a high-powered microscope. He makes a sketch in his lab notebook of one of the cells he observes. His sketch is shown below. WHICH LABEL SHOULD PEDRO USE FOR STRUCTURE 3?
chloroplast
vacuole
mitochondrion
nucleus
What is the main function of the large central vacuole in a plant cell?
it produces protein
it stores water and food
it performs photosynthesis
It protects the cell from the surrounding environment
Sharee had been ill for three days. When her mother took her to the doctor, the doctor decided not to prescribe antibiotic. He said Sharee had a virus. Why are antibiotics not able to cure viral infections?
Anibiotics kill bacteria, not viruses
antibiotics target only white blood cells
Antibiotics are not used to fight any infections
Antibiotic cause fevers that make viruses stronger.
This structure is the site of cellular respiration, it is in both plant and animal cells and is sometimes referred to as the "powerhouse of the cell".
nucleus
ribosome
mitochondria
chloroplasts
Which cellular structure is found only in Plant cells?
mitochondria
chloroplasts
cell membrane
nucleus
If a cell need to gain or lose water, which organelle is going to control that?
cell membrane
cell wall
nucleus
robosome
Which statement BEST describes how saliva helps digestion?
Saliva absorbs water from food.
Saliva kills bacteria that might be in the food found in the stomach.
Saliva absorbs nutrients and delivers the nutrients into the bloodstream.
Saliva starts the process of digestion by breaking down starch and fats in food.
Carbon dioxide is a waste product produced when human cells break down sugars to release energy. Which of the following is involved in carbon dioxide waste removal?
excretory system
cell nucleus
nervous tissue
respiratory system
What is the role of teeth in digestion?
Teeth break down solid food into smaller pieces
Teeth produce saliva that helps to break down food in the mouth.
Teeth help to push food down into the esophagus.
Teeth break down food into a thick liquid.
In biology class, Zach observes cells. Each cell has a structure that separates the inside of the cell from the environment. Which structure is Zach observing?
nucleus
cytoskeleton
cell membrane
genetic material
cell
organelle
tissue
organism
Which comparison of infectious agents (pathogens) is most accurate?
Bacteria and Parasites: reproduce asexually and are single celled
Virus and Bacteria: Both are considered living organisms, and are single celled organisms
Parasite and Virus: Both can only survive inside a host
Virus and Fungi:Both are considered non living things, and are both multicellular.
This human body system responds to invading organisms such as bacteria and parasites and attempts to kill them.
Digestive System
Reproductive System
Immune System
Nervous System
What is hierarchical organization?
shows the structure of organisms
shows the structures that make up organisms from the most simplistic to the most complex
Chart that organizes organisms
none of the above.
