Answer:
0.949367 ≈ 0.95.
Explanation:
The chi square analysis can be done by the formula as follows:
Chi square = (O-E)²/E
Here, O is observed value and E is expected value.
The tall trait follows the Mendel's law, this means the cross between F1 results in the formation of progeny with ratio 3( tall) : 1 (short).
The observed values for set I is 63 tall, 16 short.
The expected value for tall plant = 
= 59.25 .
The expected value for short plant = 
= 19.75.
Put these value in the formula for chi square analysis:
For tall plants = ( 63 - 59.25)²/ 59.25= 0.237.
For short plants = (16 - 19.75)²/ 19.75 = 0.712
Total value for set I = 0.237 + 0.712 = 0.95.
Thus, the answer is 0.95.
The answer is A! <span>Deciduous forests are not affected by a wildfire or a prescribed fire.</span>
Answer:
A. No, because budding is a type of asexual reproduction.
Explanation:
Asexual reproduction is the process where an organism makes a copy of itself by itself. It does not require a mate to make offspring.
The offspring are genetically identical to the parent.
Budding is a type of asexual reproduction where a small outgrowth of the parent breaks off to become a new organism.
Embryo development is usually only discussed in the context of sexual reproduction, where two gametes fertilize one another and a new organism that is genetically different to either parent is formed.
<span> </span><span>Bean roots will have no nodules if there are no compatible Rhizobium bacteria in the soil. The nodule is a symbiotic relationship between the plant and the bacteria. Nitrogen fixing root nodules are pinkish in color. Green root nodules indicate actively reproducing bacteria that are not fixing nitrogen. The number of nodules depends on the amount of innoculant (Rhizobium) available in the soil. Look at the photos and make an estimate like x nodules per y linear inches of root. Hope this helps.
The edible part of the radish root functions as a food storage organ. The string parts of the radish root function as normal roots absorbing water and dissolved nutrients. Bean roots have no modifications for food storage. Radish roots don't have nodules. The radish root is a "tap root". The bean root is a "fiberous root"
Beans don't grown faster than radishes because of the root nodules. Bean seeds are large. Radish seeds are small. The energy stored in the bean cotyledons helps the seedling get a fast start. The radish gets a slower start from less stored energy.</span>
Scientific law is observations and theory is explanation.
