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.

What percentage of precipitation falls back onto land? a. 78% b. 92% c. 17% d. 22%
Usimov [2.4K]

<u><em>22%  percentage</em></u><em> of precipitation falls back onto land.</em>

Answer: D. 22%

Explanation:

Water cycle is the phenomenon in which both evaporation and condensation or precipitation of water takes place. Water evaporates from the lakes, ponds, oceans and other water bodies to the atmosphere because of the heat.

The evaporated water or water vapour then form clouds which gets precipitated or condensed and falls back to the land in the form of rain, snow, hail storm, sleet etc.

However, all the forms that fall into the land have one thing in common i.e., all of them come from clouds as the clouds get heavy by the evaporated water.

DochEvi [55]

Answer: Examples of genetic variation include eye color, blood type, camouflage in animals, and leaf modification in plants.

Explanation:

Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population. Sexual reproduction promotes variable gene combinations in a population leading to genetic variation.
