Mendel studied "factors" that allowed for physical characteristics, which can have alternate versions, to be passed onto offspring. what are these factors called?
plants
traits
alleles
phenotypes

The correct answer would be alleles.

The things which were called as factors by Mendel are known as alleles these days.

Alleles refer to the alternative form of a gene. Diploid organisms carry two copies of the same, one received from mother and another received from the father.

The two copies can either be the same such as in homozygous condition or they can be different such as in heterozygous condition.

The alleles determine the trait or phenotype of the character in an individual.

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)
