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.
Answer:
Another 2014 study found that salamanders, thanks to their taste for leaf-chewing insects on forest floors, can even help fight climate change.Because of amphibians' appetites for mosquitoes, they're able to help reduce the spread of mosquito-borne illnesses such as malaria.
Answer:
The hormone oxytocin aids the birth process by stimulating: uterine wall contractions.
Explanation:
Oxytocin is a hormone that is released naturally in the body of women and that intervenes in certain physiological processes, activating behaviors at a mechanical level in specific organs such as the uterus and the breasts. In the case of the uterus, oxytocin stimulates and maintains the contraction of the smooth muscle of the uterus during labor and delivery, that is, it is responsible for the existence of contractions, which occur during intercourse, due to the distension of the uterus that occurs produced during labor.

Answer:
In DNA replication for a TTACG sequence the complementary strand would have the AATGC sequence.
Explanation:
DNA replication is the production of a new strand from an existing strand. The order of the sequence of nitrogenous bases of the new strand is complementary to the original base sequence, taking into account the complementarity of bases, where a purine binds to a pyrimidine:
Accordingly, if the sequence on the original strand is TTACG, the sequence on the new complementary strand is AATGC.
