Answer:
E. 6:3:3:2:1:1
Explanation:
Look at the attached picture to see the Punnett square for your problem.
The cross for this is snapdragons who are heterozygous for both traits so the cross would be:
<em>TtRr x TtRr</em>
As you can see in the image, you have the following genotype combinations with the corresponding phenotype combinations:
GENTOTYPE PHENOTYPE NUMBER
TTRR Tall - Red 1
TtRR Tall - Red 2
TTRr Tall - Pink 2
TtRr Tall - Pink 4
TTrr Tall - White 1
Ttrr Tall - White 2
ttRR Short - Red 1
ttRr Short - Pink 2
ttrr Short - White 1
The following phenotype combinations in summary would then be:
Tall - Pink: 6
Tall - Red: 3
Tall - White: 3
Short - Pink: 2
Short - White: 1
Short - Red: 1
So the ratio is 9:3:3:2:1:1
Answer:
Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns
hope this helps
have a good day :)
Explanation:
The result of non-reproduction is simple.
There will not be another generation of a species. Without a new generation, the parents would die off, and there would be nothing to carry on the name they had both shared.

The Answer is A) Nuclear power generates large amounts of power limited to projection of greenhouse gases.
I believe this is the answer. As per the reports in 1998, it has been calculated the emission of the greenhouse gas has reduced for nearly half due to the popularity in the use of nuclear power. Nuclear energy by far has the lowest impact on the environment since it does not releases any gases like carbon dioxide, methane which are largely responsible for greenhouse effect. There is no adverse effect on water, land or any habitats due to the use of it. Though some greenhouse gases are released while transporting fuel or extracting energy from uranium.
Have a great day. Keep asking questions!
Answer:
Yes
Explanation:
The goal of cancer gene therapy is to introduce new genetic material into target cells without toxicity to non-target tissues.The patient with recurrent or metastastic cancer is often considered incurable. A variety of chemotherapeutic agents has been used alone, and in combination, for the treatment of recurrent oral squamous cell carcinoma. However, chemotherapy is associated with well-known toxicities and has demonstrated no clear impact on survival in patients with recurrent oral cancer. Local and regional disease control is paramount, underscoring an urgent need for more effective therapies. Gene therapy has the potential to target cancer cells while sparing normal tissues. Such a strategy may be useful for recurrent disease as well as in the adjuvant setting (i.e., at the resected tumor margins).
Although gene therapy as a treatment for disease holds great promise, progress in developing effective clinical protocols has been slow. The problem lies in the development of safe and efficient gene-delivery systems. This review will evaluate the problems and the potential solutions in this new field of medicine.
