False, an environment containing no calcium is not the best for Brian shrimp egg hatching. The following evidence statements can be used to support our answer.
- Control shows 9 hatchlings after 72 hours whereas the treatment of 10mg/100ml concentration of calcium shows 17 hatchlings.
- Control shows 9 hatchlings after 72 hours whereas the treatment of 20mg/100ml concentration of calcium shows 28 hatchlings.
- Control shows 9 hatchlings after 72 hours whereas the treatment of 10mg/100ml concentration of calcium shows 39 hatchlings.

Explanation:
A classification or division essay groups objects, people, or events into categories by the characteristics that they share. Usually the writer begins with a group of people or things and then separates them into subgroups or types. There are a several steps to writing an effective division or classification essay.
Answer:
2% of the progeny will be double crossovers for the trihybrid test cross
Explanation:
By knowing the positions of genes, we can estimate the distances in MU between them per region.
- Genes A and B are 10 map units apart (Region I)
- Genes B and C are 20 map units apart (Region II)
- Genes A and C are 30 map units apart
----A-------10MU--------B-------------20MU-------------C---
Region I Region II
We can estimate the recombination frequencies by dividing each distance by 100.
• recombination frequency of A-B region = 10MU / 100 = 0.10
• recombination frequency of B-C region = 20MU / 100 = 0.20
Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:
EDRF = recombination frequency in region I x recombination frequency in region II.
EDRF = 0.10 x 0.20 = 0.02
2% of the progeny will be double crossovers for the trihybrid test cross
The best answer would be the butterfly. Many insects go through different physical changes during growth. These insects include the butterfly. From being an egg it turned into a larva and grown into a caterpillar which later on become a butterfly.
