Which statement is true about organs in the human body?

They are always composed of only one type of specialized cell.

They are the basic unit of structure and function for the organism.

They are typically microscopic and function interdependently with other organs.

They are composed of multiple tissue types working together to perform a specific activity.

Why do multicellular eukaryotes need to regulate the genes that are expressed at any given time?

If they all expressed everything, they would not have enough mRNA.

It allows the cells to specialize and form more complex tissues.

That is the only way they can determine what DNA has been damaged.

There is a limited amount of protein that can fit in a cell at a time.

There are different types of muscle tissues in the human heart performing different functions. However, cells in these tissues contain the same DNA.

Why do these cells perform different functions even though they have the same genetic information?

Different cells have different parts of their DNA activated, which determines the proteins produced.

Different cells undergo different types of cell division, which determines how active their DNA is.

Different cells are in different environments, which causes mutations in DNA.

Different cells have different shapes, which alters the DNA found in the nuclei.

A student observed onion cells in various stages of cell division. The results of two samples are shown in the table.

Based upon the data, what can be correctly concluded?

Cell division in onion cells is highly regulated, with each cell dividing at the same time.

Onion cell division is slow compared to animal cells.

Onion cells spend more time in interphase than any other phase of the cell cycle.

Prophase is the longest phase of the cell cycle in onion cell division.

The diagram shows an important biological molecule going through the process of replication.

Which statement describes why the molecule is replicating?

When a cell divides, it is important for the new cells that are produced to have complete copies of DNA.

When a cell divides, it is important for the new cells that are produced to have their own copies of RNA to make proteins.

When a cell divides, it is important for the new cells that are produced to have multiple copies of protein.

When a cell divides, it is important for the new cells that are produced to have multiple copies of carbohydrates for cell respiration.

Budding is a form of reproduction that can be seen in simple animals. The new organism grows attached to the old one and does not separate until it is mature.

How would this new organism be described?

It contains genetic material that is identical to half of the parent.

It contains genetic material that is different from the parent.

It contains genetic material that is identical to the parent.

It contains genetic material that is two times the amount of the parent.
