Answer: true
Explanation: Growth refers to change in size, like weight or length. Development refers to changes in physical, social, emotional, and intellectual abilities.
The fossil shows evidence of how animals lived on Earth in the past and shows history about animals that may be extinct now or have evolved since then, which would show development in the animal in the fossil.
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
Answer:
It’s A. A blend of genetic materail
Explanation:
I know cuz I just did it
Hey there! Lets see what I can do for you today.
1) D. Oxidizes in air
2) B. Physical; dissolve (This is because salt can also be separated from the water)
I hope this helps!
