Explanation:
Answer:
B. They use energy from the sun to make their own food
Answer:
Meteorite
Explanation:
Meteoroids become meteors when they crash into Earth's atmosphere and the gases surrounding them briefly light up as “shooting stars.” While most meteors burn up and disintegrate in the atmosphere, many of these space rocks reach Earth's surface in the form of meteorites.

Answer:
I = 62.5%
Explanation:
<u>Available data</u>:
- the wild-type DND1 gene confers resistance to attain viruses. Strains are susceptible to viruses
- The EDS1 gene confers resistance to powdery mildew, a type of fungal infection
- The genes are linked, eight map units apart on chromosome
- A third gene, IR 1. imparts resistance to certain lepidopteran leafminers and is 10 map units from EDS1 and 18 map units from DNDI
- The observed double crossover rate is 0.3%
According to this information, we can picture the position of each gene in the chromosome
---DND1----------------------EDS1-----------------------------------IR1---
║---------- 8MU---------║------------------10MU-------------║
║------------------------------18MU------------------------------║
The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.
1% of recombinations = 1 map unit = 1cM. The maximum recombination frequency is always 50%.
So, if we know the distances between genes, we know their recombination percentages.
- DND1-EDS1 = 8 MU = 8% recombination
- EDSI-IR1 = 10 MU = 10% recombination
To calculate interference, first, we need to know the coefficient of coincidence, CC.
CC= observed double recombinant frequency/expected double recombinant frequency
<em>Note: </em>
- observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals
- expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.
CC= (0.003)/(0.08 x 0.1)
CC=0.003/0.008
CC=0.375
CC = 37.5%
The coefficient of interference, I, is complementary with CC.
I = 1 - CC
I = 1 - 0.375
I = 0.625
I = 62.5%
