The correct answer is A.
Oswald Avery applied several biochemical techniques to large cultures of bacteria in order to extract and purify the "transforming principle". Their experiments showed that most probably the "transforming principle" was DNA. One of the observations leading to this conclusion was that enzymes that degrade proteins or RNA (such ribonucleases) had no effect on the "transforming principle". On the contrary, enzymes degrading the DNA destroyed the extract's transforming capacity.

jonny [76]
Emir is most probably taking a class on human anatomy. Human anatomy involves all the structures in the composition of the human body. Human anatomy can be studied either by systems (i.e. cardiovascular system, respiratory system, etc.) or by regions (i.e. thoracic anatomy, abdominal anatomy, pelvic anatomy, head and neck anatomy, etc.) depending on the course.

Animal tissues develop from embryonic germ layers. triploblastic animals have three germ layers (ectoderm, mesoderm, and endoder
natali 33 [55]

Answer;

The three statements that are true, include;

A diploblast has no mesoderm.

A pseudocoelom has the same functions as a true coelom.

In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.

Explanation;

-Diploblastic animals are animals possessing two major tissue layers. These include the outer layer (the ectoderm) and the inner layer (the endoderm). Unlike the triploblastic animals , the diploblastic animals lack the third middle layer, the mesoderm.

- Coelom is the body cavity which exists between the mesoderm and endoderm while pseudo coelom is the body cavity which is present inside the mesoderm. Both the coeloms and pseudocoeloms are used as hydrostatics skeletons.

-Coelomate animals are animals that have a "true" body cavity or coelom and organs are in cased in peritoneal membrane.
