Graph titled 'Temperature Effect on Enzyme X' showing enzyme activity decreasing linearly as temperature increases from 0°C to 100°C.

Graph titled 'Temperature Effect on Enzyme X' showing enzyme activity increasing to a peak around 50°C and then decreasing as temperature continues to increase.

Graph titled 'Temperature Effect on Enzyme X' showing enzyme activity decreasing at first and then increasing sharply as temperature increases.

All cells have certain parts in common. Which of the structures listed below do all cells have in common?
Select TWO correct answers.

Why do scientists believe that mitochondria originated from ancient prokaryotes?

mitochondria engulfed plastids which perform photosynthesis for the cell

eukaryotic cellular reproduction is always the same as bacterial reproduction

mitochondria contain DNA that is similar to that found in bacteria

prokaryotic cells have an internal membrane system

Viruses and cells are different in many ways. In which of these ways are viruses and cells most similar?

make up of outer covering

stages of life cycle

genetic material

stages of reproduction

The autogenesis theory proposes that some organelles in eukaryotic cells formed from infoldings of the cell membrane in an ancient prokaryotic cell. Which of the following structures is most likely explained by the autogenesis theory?

Cytoplasm

Flagellum

Nucleus

Ribosome

A student reads a label that states, "This energy bar will give you enough energy to make it through a long workout." Based on this claim, the student is able to conclude that the energy bar contains a high number of −

carbohydrates

proteins

some types of vitamins and minerals

a high amount of fat

This diagram compares the structures of a prokaryotic cell and a eukaryotic cell.

Which conclusion BEST explains how these two types of cells differ in complexity?

Having a nucleus allows cells to organize internal processes more efficiently than cells without one.

Membrane-bound organelles allow cells to carry out specialized functions not found in simpler cells.

Without membrane-bound organelles, cells often perform most life processes within the cytoplasm.

Fewer internal structures allow some cells to complete division more quickly than more complex cells.

Which structures, if found in a cell, would provide the best evidence that the cell is eukaryotic?

Chromosomes

Cell Walls

Carbohydrates

Internal Membranes
