Llana [10]

Answer:

The dominant phenotypes are Long flagella and one vacuole, and the recessive phenotypes are small flagella and two vacuoles.

Explanation:

As you can see in the attached table

1. For the size of the flagella we gave that:

- 241 organisms have long flagella

- 79 organisms have short flagella,

As there are more organisms with long flagella we can conclude that this is the dominant phenotype while the short flagella is the recessive phenotype.

2. For the number of vacuole we have:

- 247 organisms have one vacuole

- 73 organisms have two vacuole

As there are more organisms with one vacuole we can conclude that this is the dominant phenotype while having two vacuoles a is the recessive phenotype.

Then

Dominant phenotypes = Long flagella and one vacuole

Recessive phenotypes = Short flagella and two vacuoles

The ______ is a vital organ, and its functioning is essential to life.
attashe74 [19]
The heart is a vital organ, and its functioning is essential to life.
All your other organs may fail, and you will still be alive. Even if your brain stops working, and your heart is healthy, you will be alive in the vegetative state where you won't be conscious at all. However, once your heart stops working, you die, which means it is the most important organ in your body.
