The answer is C) 9:3:3:1
This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth
Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24
We have
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
1-DNA contains the sugar deoxyribose, while RNA contains the sugar ribose.
2-DNA is a double-stranded molecule, while RNA is a single-stranded molecule.
3-DNA is stable under alkaline conditions, while RNA is not stable.
Hope this helps you!!!:) You can translate this into Spanish!
I believe it's called a sex-linked trait, if I'm remembering correctly. This is because men do not have an X chromosome, therefore it would be linked to females.
Secondary succession is the ecological succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession
Answer:
c The trees will grow and the forest will be restored to its original form.
Explanation:
The ashes from the old trees will serve as nutrient for the new plants. its restores back the ecosystem because the old tress and ashes will decay which will return nutrient to the soil.
the new seedlings will be exposed to fresh air and sunlight which improve there germination.
