1

Male peacocks have colorful tail fewthers and female peacocks do not.

Sexual selection

2

A gardener accidentally produces an orange flower by mating yellow flowers.

Mutation

3

Nitrogen

An atom

4

Output of the light-dependant reaction of photosynthesis

ATP

5

Which molecule is input to Calvin-Benson Cycle

Carbon dioxide

6

Krebs cycle

Stage of cellular respiration which releases carbon dioxide as a product

7

Electron transport chain

Stage of cellular respiration which uses the most energy and produces the most ATP molecules

8

What metabolic process do fast twitch muscle fibers carry out?

Fermentation

9

Feementation uses sugar in the absence of

O 2

10

Electron

Negative charge and found in the shell of an atom

11

Proton charge

+1

12

Ionic bonding

When one atom transfers an electron to another

13

Covalent Bonding

Atom shares and electron with another

14

Nitrogenous base

Substance found in ATP

15

Initial step of glycolisis

Energy is being released from ATP to power the conversion of glucose

16

A protein

A polymer consisting of 358 amino acids linked together covalently

17

A molecule consisting of a chain of glucose monomers linked together- what is its function

To store energy

18

Telophase I

A cell is currently dividing, the two new daughter cells will be haploid, but the DNA they contain is still replicated. Chromosomes have seperated but have not yet begun the second round of division

19

Prophase II

Homologus pairs of chromosomes have seperated into two cells. Sister chromatids in each cell have not yet lined up in the middle of the cell

20

Meiosis

Cell division that results in sex cells

21

Sister chromatids separate

Both meiosis and mitosis

22

Metaphase

Dna structure: The centromere at the center keeps DNA lined up at the cell's equator

23

Metaphase to Anaphase

Sister chromatids are aligned along the center of the cell then pulled apart into seperate chromatids

24

Prophase

--

25

Anaphase

Sister chromatids are being separated and moving towards opposite poles of the cell

26

DNA

Organic molecule present in chromosomes that contain hereditary material passed from one generation to the next

27

Cytokinesis

A cell has divided its chromosomes into two nuclei. The cytoskeleton of the cell is currently pinching the cell in the middle form tow new cells.

28

Histones during S phase

Organize and help unwind DNA so the replication enzymes can access it

29

Flagellum

Locomotion and sensing

30

Eykaryotic Cell

- Contains mitochondrion
- membrane: lipids and proteins
