1.

Different types of cells, such as heart and lung cells, are created by the expression of ---

different genes in a tightly controlled process

two forms of the same gene in a one-step process

parts of a gene in a semiregulated process

the same gene in a random process

Asemmisa {{asɛmmisaAhyɛnsode}}

2.

As unspecialized cells mature, what controls their development into specific cell types?

The age of neighboring cells

The rate at which the cells grow

The nutrients available to the cells

The genes expressed within the cells

Asemmisa {{asɛmmisaAhyɛnsode}}

3.

Environmental factors typically activate genes in a cell by causing the cell to —

transcribe specific DNA segments to mRNA for translation

form haploid gamete cells through meiosis

produce identical daughter cells through mitosis

fuse with another cell to increase the size of its genome

Asemmisa {{asɛmmisaAhyɛnsode}}

4.

As a fertilized egg divides, the cells differentiate because they --

contain a lipid bilayer

can clump together

metabolize sugars rapidly

have specific genes activated

5.

Below are two cell types. One is a neuron (nerve cell) and the other is a hepatocyte (liver cell).
Which of the following statements is correct AND explain why the cells have different functions.
Statement 1: Each of these cells carries the same DNA.
Statement 2: Each of these cells carries different DNA.

6.

A developmental biologist is researching how cells in a frog embryo differentiate into various tissues. She discovers that certain cells only start developing into nerve cells when exposed to a specific hormone produced by the embryo.
What does this observation suggest about the role of hormones in cell differentiation?

Hormones provide energy needed for cell growth.

Hormones ensure that all cells remain identical and undifferentiated.

Hormones signal specific genes to activate or deactivate, influencing cell specialization.

Hormones only assist in cell division without affecting differentiation.

7.

Researchers are studying the effect of diet on cell differentiation in fruit flies. They discover that when larvae are given a diet enriched with certain nutrients, they develop into queens, whereas those on a standard diet become worker bees.
What can be inferred about the role of diet in cell differentiation?

Diet ensures that all cells remain undifferentiated.

Specific nutrients can trigger changes in gene expression that result in different cell specializations.

Diet only provides energy without affecting cell differentiation.

The type of diet does not influence cell differentiation.
