Biology Vocabulary EOC

These diagrams show a variety of cells from the same organism. How can cells from the same organism have such different shapes and functions?

• As each cell differentiates, the DNA changes so that each type of cell has different DNA once it reaches maturity.

• Mutations in the cells' nuclei lead to new combinations of DNA, resulting in different shapes and functions in the different types of cells.

• During differentiation, different parts of the DNA in each type of cell are activated, resulting in the different structure and function of the cells.

• During differentiation, different types of cells produce proteins which destroy the nonactive DNA, leading to cell specialization.

Which statement best explains why animals are considered heterotrophic?

• They are able to produce food through the process of photosynthesis.

• They are able to produce food through the process of respiration.

• They are able to obtain nutrients by decomposing plant and animal tissue.

• They are able to obtain nutrients by consuming other organisms or their products.

Which effect could a mutation in mRNA have on the production of proteins?

• The protein produced will have a different identity.

• The protein produced will have a coiled shape.

• The protein produced will produce excess nitrogen.

• The protein produced will produce excess water.

Many of the proteins in the human body are enzymes that catalyze chemical reactions. What is the relationship between enzymes and activation energy?

• When an enzyme catalyzes a reaction, it increases the activation energy of the reaction

• When an enzyme catalyzes a reaction, it increases the activation energy of the product.

• When an enzyme catalyzes a reaction, it decreases the activation energy of the reaction.

• When an enzyme catalyzes a reaction, it does not affect the activation energy of the

  reaction

(1.02 MC) SC.912. . L.14.1 To help patients replenish bodily fluids quickly during an illness, doctors need to understand how cells behave in their environment. Doctors have confidence in what they know about how cells behave because

• cell theory has been tested, refined, and observed to be true over hundreds of years

• large medical institutions have conducted their own experiments justifying cell theory

• the basics of cell theory have not changed much since the original experiments

• what we know about cell theory has been published in reputable journals

SC. 912.L.14.1 Which of the following best summarizes why the technological invention of microscopes was important to biology?

• It allowed for development of the cell theory.

• It created a means of funding for cell research.

• It created public interest and support for research.

• It proved that cells could form spontaneously.

SC. 912.L.14.1 Early elements of the cell theory followed soon after the development of Hooke's light microscope. What does this relationship suggest about the evolution of the cell theory since Hooke?

• Isolated scientists contributed pieces of the cell theory to form the whole.

• Improvements in technology are closely related to changes in the cell theory.

• Progress on the cell theory was delayed by a lack of technological progress.

• Scientists needed to focus less on cells and more on microscope development.
