The correct answer is a eukaryotic cell. The eukaryotic cell is a bacteria cell that has the same structure as more complex cells. Eukaryotic cells have many structures that help to maintain homeostasis and also to provide energy for the protein synthesis.
<h2>False </h2>
Explanation:
The immune system develops integrated innate and adaptive modules that are pathogen type-specific and no single response can effectively control all types of pathogens
Both innate and adaptive immune system operate in cooperative and interdependent ways
Innate immune system is present since birth in an organism and is non specific in nature which means acts against all foreign antigens and molecules and provides first line of defense against pathogens
Adaptive immunity system is the acquired one which is capable of recognizing and selectively eliminating specific foreign antigens and is antigen specific which means can discriminate among different antigens; also has the ability to respond to various kinds of epitopes of pathogens
Answer:
The Hay-flick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis.
Answer:
I would say We don't have enough evidence or Cell theory is still changing.
Explanation:
There are so many cells in everything so it's almost impossible to know exactly what is going on. Theories about cells have been going on for over 500 years, and we still don't know exactly what is what.
Cutoff signals are signals used by the animals for communication between them. These signals are behaviors. Examples are: the animal freezes, turns the back to other animals, moves away, ....
Cut-off signals are usually given after a conflict. One reason animals use cutoff signals is to:
D. encourage compromise between potential adversaries
If cut-off signals are not respected, conflict will escalate.
