Answer: The thoracic cavity is separated from the abdominopelvic cavity by the diaphragm. The thoracic cavity is further separated into the pleural cavity which contains the lungs and the superior mediastinum which includes the pericardial (heart) cavity.
Explanation:
The given statement is True.
<u>Explanation:</u>
The Charles Darwin developed the theory called Darwinism theory of evolution. The theory states that all the species of the organisms arises and developed through the small, inherited variations in the organisms that increase the individual ability to complete the survive and reproduce.
The individual species are not having identical traits that are passed from the generation to generation. The offspring are born that can survive, only the survive of the completion for resources will reproduce; he describes how the species can change in shape and character through the selective breeding.
Answer:
The correct answer is: semi-conservative.
Explanation:
DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.
DNA replication is <u>semi-conservative because one strand of DNA is new and the other one is the old strand</u>. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.
DNA replication is <u>not a one-step process</u>, as it takes several complicated steps in which <u>lots on enzymes participate</u> (like DNA polymerase and DNA helicase).
DNA replication is <u>also carried by prokaryotic cells</u>, though it's a much simpler process.
Among these options, the one which is the broadest group used to classify organisms is D. class.
Although it is not the broadest group ever phylum and kingdom are above it), it is the broadest one here.
