||||
compare the temeratures and length of days during th winter months in the norther hemisphere to the southern hemisphere. | during the winter months in the northern hemisphere the southern hemisphere has higher temperatures and longers days

🗑
|
||||
where does photosynthesis take place? | chloroplast
🗑
|
||||
what is the equation for photosynthesis? | 6CO2+6H2O+ light energy
🗑
|
||||
what are factories? | chloroplasts are analogous(similar)
🗑
|

what are the stages of exocytosis? | 1) large particle are packed in vesicles 2)the vesicle fuses w/ the cell membrane 3) the cell releases the particle
🗑
|
||||
what are the stages of endocytosis? | producers are the source of energy for consumers without producers, consumers wouldn't live
🗑
|
||||
why are prodcuers important to the survival of all other organisms? | after the chromosomes are copied through mitosis
🗑
|
||||
when does the parent cell divide during asexual reproduction in eukaryotes? | 23
🗑
|
||||
how many chromosomes does a human sex cell have? | there are 2parents that combine their chromisomes which means more variety in offspring
🗑
|
||||
sex cell | an egg or sperm that carries half the amount of chromosomes of other cells
🗑
|
||||
probability | the mathematical chance that an event will happen
🗑
|
||||
homologous pair | a pair of chromosomes with similar information
🗑
|
||||
meiosis | cell division that produce sex cells
🗑
|
||||
evolution | the process by which populations inherit physical changes over time
🗑
|
||||
mutation | changes in an organisms DNA
🗑
|
||||
natural selection | when organisns with specific traits survive and reproduce at a greater rate than the organisms without those traits
🗑
|
||||
what did mendal call the trait that seems to fade nto the backround in his genetic crosses? | recessive trait
🗑
|
||||
what is the difference between asexual and sexual reproduction | asexual= 1 parent & sexual = 2 parents
🗑
|
||||
genes are part of ___ that give instructions to the cell for expressing traits. | DNA
🗑
|
||||
How are genes and inherited traits similar and how are they different | Genes are the instructions from which traits are inherited
🗑
|
||||
What is the probability of the phenotypes and genotypes of crossing 2 heterogeneous genes? | Genotypes BB=25%; Bb=50%. bb=25%
🗑
|
||||
Explain asexual reproduction results in more-diverse offspring than asexual reproduction | In asexual reproduction the cells are just copied from the parent. In sexual reproduction the geners from the 2 parents are combined to make a new individual w/its own genetics combination

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
