An organism that reproduces sexually has a diploid number of 30. How many
Strike441 [17]

Answer:

Gamete of organism has a haploid number of chromosomes.

2n = 30

n = 15

A diploid cell containing 30 chromosomes will result in 15 chromosomes in each of the 4 daughter cells after meiosis occurs.

After first nuclear and cellular division (Meiosis I), each daughter cell will only have 15 chromosomes as homologous chromosomes are broken apart at Anaphase I of meiosis I. Chromosomal number is halved. After the second nuclear and cellular division (Meiosis II), each daughter cell will also have 15 chromosomes. This time, instead of the chromosomal number being halved, their chromosomal contents are halved. Sister chromatids are separated at Anaphase II of Meiosis II, resulting in daughter chromosomes each.

Hope it helped!(:

In plant cell what does the vacuole do

<span>I found this on a website..... Hope this helped :)

"In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food."</span>

A newly discovered solar system is found 300 billion kilometers from the sun. How many AU does this represent? Show your work.
Aleksandr-060686 [28]

1 kilometer = 6.68 × 10^{-9} (<<<AU is in scientific notation here)

To convert 300 billion kilometer (3,000,000,000 km)  into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 × 10^{-9})

3,000,000,000 × (6.68 × 10^{-9}) =  20.04 AU

Hope this helped!
