LAB AIDS: ONB Activities 1-6 v2

The term for factual information or data that can either support or refute a claim is known as

• evidence

• pattern

• trade-off

• vector

• matter

Answer explanation

The question asks for the term that describes factual information or data that can support or refute a claim. The correct answer is 'evidence'. This is because evidence is the information that supports or refutes an idea or claim. Other options like 'pattern', 'trade-off', 'vector', and 'matter' do not accurately describe this concept.

The ​ (a)   refers to the ideas that all living things are made up of cells, cells are the basic unit of life, and new cells come from pre-existing cells while the ​ ​ (b)   states that microbes can cause infectious diseases.

• cell theory

• microbe

• germ theory of disease

• theory of evolution

• theory of disease transmission

Answer explanation

The question refers to two different theories. The first blank refers to the 'cell theory' which states that all living things are made up of cells, cells are the basic unit of life, and new cells come from pre-existing cells. The second blank refers to the 'germ theory of disease' which states that microbes can cause infectious diseases.

Match the following

• energy

• the ability to cause an object to change, move or work

• pattern

• the stuff that makes up all living and nonliving objects.

• matter

• something that happens in a repeated and predictable way.

• trade off

• desirable outcome given up to gain another desirable outcome.

Liam is using a microscope in his biology class to observe a specimen. He switches to the high-power objective lens. What is the total magnification of the microscope now?

• 43x

• 53x

• 100x

• 430x

Answer explanation

The total magnification of a microscope is calculated by multiplying the power of the eyepiece by the power of the objective lens. In most microscopes, the eyepiece lens is 10x and this particular high-power objective lens is 43x. Therefore, when Liam switches to the high-power objective lens, the total magnification becomes 430x, or (10x)*(43x).

To enlarge an image of an object and the extent to which an image of an object is enlarged is known as ​ (a)   .

• magnification
• field of view

• high power objective

• microscope

Answer explanation

The correct term for the extent to which an image of an object is enlarged is 'magnification'. Magnification refers to the process of making an object appear larger, typically using optical instruments like microscopes. The other options, field of view, high power objective, and microscope, are related to magnification but do not specifically describe the enlargement of an image.

Match the following

• Cell Membrane

• The outermost layer of certain cells that gives shape to the cell and protects it. Found in plant and bacterial cells.

• Chloroplast

• The part of the cell that contains the genetic material.

• Cell Wall

• The organelles that produce most of the energy that cells need.

• Mitochondria

• The structure that separates the cell from its external environment.

• An organelle that contains chlorophyll and in which photosynthesis occurs. Found in plant cells and other photosynthesizing cells.

Oliver, Aria, and Nora are learning about mosquitoes and how they can transmit diseases like malaria and dengue. They discovered that mosquitoes are an example of an organism that spreads disease-causing microbes from one host to another without getting sick themselves. What is the term for such organisms?

• vector

• infectious disease

• outbreak

• unicellular

Answer explanation

The term for organisms that spread disease-causing microbes from one host to another without getting sick themselves is 'vector.' In this case, mosquitoes are vectors as they transmit diseases like malaria and dengue without being affected by the diseases themselves.

Which organism is an unicellular organism that, like many prokaryotes, are made up of just one cell, like the microbe shown in the photo?

Which organism is a multicellular organism that, like many eukaryotes, are made up of many cells, like the plants shown in the photo?
