The eukaryotes are the organisms that contain the genetic material (DNA) inside the membrane enclosed nucleus. These organisms contain membrane bound cell organelles, such as mitochondria, Golgi apparatus etc. as opposed to the prokaryotic organisms that contain no membrane bound organelles and no nucleus. The presence of enclosed nucleus and membrane bound organelles helps in determining that the cell is Eukaryote, but the presence of cell wall will be of no help as both the prokaryotes as well as eukaryotes contain cell wall.
Hence, the correct answer is 'cell wall'.
Three physical properties are freezing, boiling, and melting.
Answer:
A. terminators of replication.
Explanation:
For the proper transmission of genetic information from a mother cell to each daughter cell, the cell copies or replicates its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set. And in order to duplicate and segregate correctly, chromosomes must contain three functional elements which are origins for initiation of DNA replication, the telomeres and the centromeres. Terminators of replication is not a required element.
A heterogeneous mixture is where two or more substances that form the mixture, are <u>not</u> evenly distributed throughout
Answer:
The correct answer is- b. P: coughing; C: saliva; B: complement system
Explanation:
Body show physical, chemical and immunological response against foreign antigen to protect the body from them. Coughing, sneezing, skin, respiratory tract, gastrointestinal tract comes under physical barrier. They restrict the bacteria to get into the body.
Chemical barrier includes saliva, tear, sweat, mucus that helps in killing the pathogen at the outer body surface. Antibodies, immune cells, complement system comes under immune response which helps in destroying the pathogen which are present in the body.
