1.Carbon is the basic building block for all forms of life on ...
Review the graphic and select the best response based on that data.
a
By mass, humans are mostly oxygen.
b
Humans are mostly water.
c
Elements making up the human body are worth about $600.
d
By volume, humans are 10% hydrogen.
Question 28
Viruses are often referred to as non-living infectious particles as they lack many characteristics of living organisms like cellular structure. They do not have the ability to carry out reproduction and metabolism without a host cell.
True or False and why?
a
True - if a living organism requires a cellular structure, even if they can reproduce - they are by definition non-living.
b
False - viruses are able to reproduce and use energy without a host cell.
c
False - viruses, like bacteria, do not have a cellular structure and yet, bacteria are considered living organisms.
d
False - viruses do have a clear cellular structure, including a cell membrane called an envelope.
Question 29
Julia and Vinay are learning about cells in their high school Biology class. To gain a deeper understanding of cells, their teacher is having them perform a laboratory experiment to identify unknown cell types. Julia and Vinay must create a hypothesis based on the cell types they believe they will identify. Then they will be given three microscope slides that contain samples of different cell types. During the experiment, Julia and Vinay will answer analysis questions, and after the experiment, they will complete a laboratory report with a conclusion.
After Julia and Vinay got their microscope slides, they set them up on their microscope. The images show the three cell types Julia and Vinay viewed while looking under their microscope.
Sample X
Sample Y
Sample Z
Julia and Vinay both agree that the cells found in Sample Y come from an animal. They infer that the organism the cells were extracted from produces gametes to create offspring. Select the best advantage associated with this method of reproduction that Julia and Vinay could list in their laboratory notebook.
a
It only requires one parent.
b
It can quickly increase a population.
c
Genetically identical offspring are produced.
d
There is genetic variation among the offspring.
Question 30
The two steps in photosynthesis are the light-dependent reactions and the Calvin cycle.
Which of the following is true regarding these two steps?
a
The light-dependent reactions use ATP from the Calvin cycle, and the Calvin cycle uses energy from absorbed sunlight.
b
The light-dependent reactions take place in the thylakoid membrane, and the Calvin cycle takes place in the stroma.
c
The Calvin cycle converts water molecules into oxygen gas as a byproduct of its reactions.
d
During the light-dependent reactions, carbon dioxide is fixed to produce sugars that form glucose.
The correct answer is:
b
The light-dependent reactions take place in the thylakoid membrane, and the Calvin cycle takes place in the stroma.
