Answer:
25% heterozygous tall
Explanation:
If we take the F1 generation as parents and let them self-fertilise, we have 4 crosses.
The first one for homozygous tall, then we have 100% AA.
The second and third one for heterozygous tall and we have 25% AA, 50%Aa and 25%aa for each of them.
The last one would be for dwarf, and we'll have 100%aa.
Adding all of them, we'll have
AA = 100 + 25 + 25 = 150%
Aa = 50+50 = 100%
aa = 100 + 25 + 25 = 150%
as we had 4 crosses, so dividing the total percentages by 4, we'll have,
AA = 37.5%
Aa = 25%
aa = 37.5%
:. The percentage of heterozygous tall would be 25%.

Answer:
a. A natural geological challenge that exists in my environment is a fault zone known as the San Andreas Fault. It's a major geological landmark where two tectonic plates meet in California. People in my area are prepared for the event of an earthquake by packing emergency clothes, food, water, shelter, etc. in the event of a major earthquake. Scientists believe that California is past due for a major earthquake in the 6.0-8.0 range that could happen any day now. Hope this helps :)
Explanation:
Electrons are found outside the nucleus.
Its important not to put a person making an emergency call on hold because since it might be a patient who is a serious case and might lose consciousness. It is therefore always important to obtain the name, phone number, and location at the start of the call so that the patient can be found if they lose consciousness or is disconnected. Additionally its is important to make sure one stays connected with the patient until help arrives to ensure their safety.
Answer:
The correct answer is b. All round seeds
Explanation:
If an RR plant is crossed with an rr plant than all the phenotype will produce round seed and the frequency of the Round seed plant to wrinkled seed plant would be 4:0.
R R
r Rr Rr
r Rr Rr
So all the phenotypes will be heterozygous dominant for the round seed which means that all phenotypes will have a single dominant allele for round seed which is enough to express round seeds in the phenotypes.
