Arada [10]

Answer:

a. autotriploid of species A: 63 chromosomes

b. autotetraploid of species B: 96 chromosomes

c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes

Explanation:

<u>For a.</u>

this species will have 3 haploid sets of chromosomes ('tri' means 3)

one haploid set = 21

21 × 3 = 63 chromosomes

<u>For b.</u>

this species will have 4 haploid sets of chromosomes ('tetra' means 4)

one haploid set = 24

24 × 4 = 96 chromosomes

<u>For c.</u>

there are two ways to do this:

1) two sets of chromosomes from species A and one from species B

42 + 24 = 66 chromosomes

2) one set of chromosomes from species A and two from species B

21 + 48 = 69 chromosomes

Hope that answers the question, have a great day!

The orbital radius of venus is 0.72 AU. what ia this distance in kilometers?
Arturiano [62]

108 million kilometers. To solve this problem, you must perform a simple unit conversion calculation. 1 AU = 150,000,000 km is the conversion factor. Take the radius of Venus, .72 AU, and multiply it by 150,000,000 km/1 AU. You flip the conversion factor so that the units of the original distance in the numerator cancel the units in the denominator of the conversion factor. completing the calculation gives you 108,000,000 km
