Answer:
Transforming material would be the genetic material.
Explanation:
Griffith was performing the tests to know how bacteria cause pneumonia for which he selected two strains.
The R strain was avirulent but S bacteria was virulent which in one case when he heat killed the virulent bacteria and then injected them with the avirulent bacteria, he found that the avirulent bacteria that is R bacteria transformed into the virulent bacteria.
When he isolated the S bacteria, the R bacteria were still able to cause the disease in mice which shows that the bacteria were transformed permanently and since the disease-causing ability is passed on to the generations, therefore, the disease-causing factor is present on the hereditary material or the transforming material is the hereditary material.
The correct answer is B. Competition for food and shelter would increase, so the toucan population would decrease.
Explanation:
Birds such as toucans rely on trees to obtain food, shelter and a place to nest. Due to this, a decrease in the population of trees would cause food, shelter, etc. are limited, and therefore not all toucans can have access to it. This situation will lead to competition between toucans, and a decrease in the population of these birds. This decrease would be the result of toucans having fewer chances to survive and reproduce because food and shelter play an important role in these two aspects. According to these ideas, it is likely "competition for food and shelter would increase, so the toucan population would decrease".
Answer:
As well as producing hormones, vaccines and other drugs genetic engineering has the potential to cure genetic diseases through gene therapy. ... Genetic engineering: Process of inserting new genetic information into existing cells in order to modify a specific organism for the purpose of changing its characteristics.
