Explain why a sexual reproduction results in offspring with identical DNA/genetic information and sexual reproduction results in offspring will be varied DNA/genetic information.

In asexual reproduction, you are essentially producing clones of the parent.  There is no genetic variation between parent and offspring - think of mitosis.

In sexual reproduction, you have several chances for genetic variation.  The first occurs in meiosis 1, when homologous pairs line up and crossing over occurs.  Then in meiosis 2, different combinations of chromosomes (some from mother, some from father) could end up in the gamete cells.  Finally, when the gametes (egg and sperm/spore) come together in fertilization, that represents a brand new combination of chromosomes, and therefore alleles, than either of the parents had.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
