Pollen graph problem

Purple and long: 25% Purple and round: 25% red and long: 25% red and round: 75%

Photosynthesis vs. Temperature Experiment Which statement is supported by the data in the graph?

The rate of oxygen production is greatest in section M

A scientist is examining a pedigree that includes several generations of an organism with XX/XY chromosome sex determination. Which pattern of inheritance would support the hypothesis that the trait being studied is a recessive sex-linked trait found on the X chromosome?

The trait is mostly expressed in males who have a maternal grandfather with the trait

A red blood cell is placed into an aqueous solution. The red blood cell has a lower concentration of protein and sugar than the aqueous solution, as shown in the diagram. In the diagram, the volume of the cell is equal to the volume outside the cell. What is most likely to occur?

Water from the red blood cell will diffuse into the solution

Individual 6 is female. What is the genotype of individual 6?

XBXb

Butterfly genotypes problem (part b has 10 boxes)

a: aa b: Aa Aa Aa Aa Aa AA AA AA aa aa

the diagram depicts the process of crossing over, which occurs between homologous chromosomes during gamete formation. What is the result of this process

an increase in offspring variation

Onion cell problem

both 3%

A group of students studied four different cell specimens under a microscope and recorded information about each cell in this table. Which cell specimen is a prokaryote?

cell 3

Which pair of organelles works together to give structure and support in animal cells?

cell membrane and cytoskeleton

A scientist isolates a number of non-photosynthetic prokaryotes. which structure would be found in these cells

cell walls

The diagram shows an incomplete cross section of a cell membrane. Three different particles are shown moving across the membrane into or out of the cell. Determine the appropriate transport mechanism of each particle and move the correct membrane segment into each blank box to complete the cross section diagram Choices: atp pump, channel, phospholipids

channel, phospholipids, atp pump

Which statement explains the effect of temperature on the rate of photosynthesis?

enzymes involved with plant photosynthesis are disrupted at temperature about 25

Which type of macromolecule stores energy and provides thermal insulation for the body?

lipid

the presence of which structure helps classify an organism as eukaryotic?

nucleus

A student is asked to draw for cells? Which drawing is a representation of a prokaryotic cell?

one with the flagella that's rectangular

Which structural feature of the cell membrane allows molecules such as oxygen and carbon dioxide to diffuse into and out of the cell?

the cell membrane is made up of two layers of phospholipids

Which statement about the cells is accurate

the four cells have identical DNA sequences

Some bacteria have developed a resistance to antibiotics through random mutations. One such mutation allows bacteria to produce enzymes that inactivate the antibiotics when they enter the bacteria. Which statement describes how this mutation occurs?

the mutation occurs when the nucleic acids are replicated

In the answer document, select all of the statements that describe the particles or their movement based on the time-lapse diagram

the particles crossing the membrane do not have a charge The movement across the membrane does not require added energy the particles crossing the membrane could be water or oxygen
