Prokaryotic
-no nucleus
-unicellular
-does not contain cell organelles like the mitochondria
-smaller and less complex then eukaryotes
-domains Archaea and Bacteria
-DNA is not in a nucleus
Eukaryotic
-nucleus
-can be multicellular
-larger and more complex than prokaryotes
-does contain cell organelles like the mitochondria
-domain Eukarya
-DNA contained in nucleus
Answer:
A) & B)
Explanation:
A) There are certain viruses that are present in both healthy and disease people.
Example: Polio virus is found in many human but it causes disesease in only 1% of human.
B) Viruses require host machinery for replication so they may not replicate in pure culture.
The postulate C is also violated, the virus may not produce disease in non-human experimental host because of inappropriate animal or vaccinated animal etc. Others exception includes, the same disease may be caused by various organisms and different organisms can also cause the same disease.
Answer:
Cell Division. Read explanation
Explanation:
It wouldn't be any of the sex cells so that would take out gene activity and offpsring. The only thing that changes the somatic (body) cells would be the slowing of cell division which I would assume is the correct answer.
<span>"Carrier proteins bind to the substances they transport across the membrane via facilitated diffusion, whereas channel proteins provide a pore for substances to move across the membrane via facilitated diffusion."
This is the most correct option.
The main difference, when comparing these two gates of transportation across a membrane through the same process (via facilitated diffusion or any other), is that carrier proteins bind to the substances they transport and only communicate with one environment of the cell (whether intracellular or extracellular) at the time, while channel proteins let substances move across the membrane without any binding being opened to both cell environments.</span>
Answer:
The correct answer is - kidney.
Explanation:
Osmoregulation is the process that bilogical system perform for the maintain osmotic balance in the blood plasma. There is a regular intake of electrolytes, water in the biological system from various proces.
The kidneys assists in the exported excessive electrolytes and water which is excreted to help in the maiantaining blood plasma on istonic level and prevent i from hypertonic or hypotonic condition that could lead to explosde of the cells. It return the amount of water from the transported amount of electrolyte and water so it can maintain the osmotic pressure in the cell.
