the correct answer is D. genetic information is passed from both parents to offspring
Answer:
its B and D
Explanation:
Chase and Hershey conducted experiments in 1952, using bacteriophages that revealed DNA, not protein, was the genetic material.
The experiments that revealed protein was not the genetic material were conducted by Martha Chase and Alfred Hershey in 1952. They were studying a bacteriophage, a virus that infects bacteria, which has two main structures: a protein coat known as the capsid, and a nucleic acid core that contains either DNA or RNA.
Hershey and Chase used radioactive markers to label the protein coat and DNA of the bacteriophage, respectively. Through their experiments, Hershey and Chase discovered that only the DNA entered the host bacteria upon bacteriophage infection, suggesting that DNA, not protein, is the genetic material. Their work was instrumental in establishing DNA as the molecule responsible for heredity.

The percentage of the offspring that will be expected to have the TTYy allele combination is 25%.
A cross or breeding experiment's genotypes can be predicted using the Punnett square, a diagram with squares. This square bears Reginald C. Punnett's name, who created this invention in 1905.
Two heterozygous plant crosses will result:
T T Y y
T TT TT y Yy yy
t Tt Tt y Yy yy
The ratio of TT = 1/2 The ratio of Yy = 1/2
The total ratio of TTYy is 1/2 x 1/2 = 1/4 = 25%.
Therefore, 25% of the progeny should carry the TTYy allele combination, according to expectations. The offspring produced is heterozygous.

Answer:
1/4 in fraction and 25% in percentage
Explanation:
When Mendel crossed purebred purple flowering plants (PP) with purebredwhite flowering plants (pp), the flower colors of the resulting offspring is: 100 percent purple.
Therefore, it can be said that when Mendel crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp), the flower colors of the resulting offspring is: 100 percent purple.

She is a carrier of hemophilia but does not have the condition
(I got it correct on Gradpoint)
Answer:
is 1%
Explanation:
Answer:
The seals would receive about 1% the amount of energy as the crabs.
Explanation:
The seals would receive about 1% the amount of energy as the crabs. The 10% rule says that as you move through an energy pyramid, the available energy decreases by about 90%, leaving 10% available energy for the next trophic level. Since the energy moved through two tropics levels, there is only about 1% available: 100% to 10% to 1%.
