Answer:
The correct answer is "Nitrogen will only become available to other, nearby plants when the nodules or the nitrogen-fixing plant itself dies".
Explanation:
Nitrogen fixing bacteria maintain a symbiotic relationship with plants. Bacteria performs nitrogen fixation providing the plant with ammonia, while bacteria has a safe place and nutrients to prosper. This relationship is very intimate because it occurs at the root hair of the plant at structures called nodules. Therefore, nitrogen will only become available to other, nearby plants when the nodules or the nitrogen-fixing plant itself dies
Answer:
it has partial charges
The hydrogen gives a positive partial charge
The oxygen gives a negative partial charge
Oxygen is way more electronegative than hydrogen therefore the molecule will be polar.
Answer: All of the offspring are brown. The chances of getting a brown deer is 100%.
Explanation: The buck is homozygous dominant, meaning he has two of the brown (B) allele. The doe is white, and since the allele for a white coat is recessive, it has to have two white (b) alleles.
Set up a Punnett square with BB on one side and bb on the other. The results of this are 4 offspring all with the genotype Bb. Because brown (B) is dominant, all of them are brown.
To find the chance of getting a brown deer, take the number of brown deer (4) and divide it by the total number of outcomes (4). This gets you 4/4 or 1. As a percent, that would equal 100%.
