The nucleus is the largest and the most important cell organelle in a eukaryotic cell. A nucleus is a membrane-bound organelle that houses the genetic material of eukaryotes in DNA. The nucleus consists of protein fibres or the DNA inside chromatin fibres. Nucleoids contain the genetic material of prokaryotes in the cytoplasm. The nucleoids usually consist of a single chromosome.
Let us look at more difference between nucleus and nucleoid in the table given below.
A cell is like a factory because it has all the different parts! Tell me if you want more detail,I would be glad to give it!
Answer:
Explanation:
The scientific method. When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis often in the form of an if/then statement, the results aiming to support or contradict a theory.
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.
