What is a living thing that carry out its life activities?
A cell. Cells are the basic unit of life. Unicellular organisms can perform life tasks on its own, and they are one cell. Multicellular organisims have more than one cell (you and I), and can also perform life tasks.
What is the use of organisms to perform practical tasks for humans called?
Biotechnology
How did cell specialization occur in multicellular organisms?
Specialization occurred during the process that moved from unicellular organisms to multicellular organisms. Selection pressures favored having numerous distinct cells that work in tandem over individual cells that did not and then further cells that were in complete union with each other over those that work in tandem. There are a number of intermediate steps between unicellular and multicellular organisms. Probably the most clear "midway" point is the colonial organism of which the extant Volvox is one of the best examples. (Admittedly Volvox itself is only 200 million years to present old, so it is not a remnant of this transition, but is similar to what scientists surmise was part of the transition that led to the development of multicellular organisms.) In a colonial organism, numerous unicellular organisms work in tandem to achieve goals (similar to how geese fly in flocks even though each is autonomous). The required communication would select cells that more effectively communicate with each other, leading to cells that can function as part of the same organism. In Volvox, we also already see small degrees of specialization. There are distinct somatic cells which perform day to day activities such as motion and photosynthesis and germ cells which are primarily responsible for replication. Since no cell could adequately perform both functions well, this partial specialization is favored. In organisms performing more complex tasks, this differentiation in tasks would naturally be selected for enlargement. You can read more about it in the Royal Society report below.
Why does complex multicellular organisms need a nervous system?
Complex multi cellular organisms need a nervous system to be able to contact the brain and be informed on which tasks need performing. Hope this helps...
What tabs does Word display when performing certain tasks or work with objects such as pictures or tables?
Word displays contextual tabs when you perform certain tasks or work with objects such as pictures or tables. A formatting mark is a character that Word displays on the screen but is not visible on a printed document.
The cells of multicellular organisms are specialized to perform different tasks?
True
What is a living thing that carry out its life activities?
A cell. Cells are the basic unit of life. Unicellular organisms can perform life tasks on its own, and they are one cell. Multicellular organisims have more than one cell (you and I), and can also perform life tasks.
In what kinds of organisms is the cell specialization a characteristic?
Either multicellular or unicellular organisms. By the way are you using Prentice Hall Biology California because many of your questions are from the book? prentice hall florida actually
How are cells usually organized in large mulicellular organisms?
cell, tissue, organ, organ system that's it I am a 5th grader
When you perform certain tasks Access displays tabs called what?
Access displays tabs called_____ when you perform certain tasks.
Cells within multicellular organisms are specialized to perform specific tasks. What is one advantage of specialized cells?
Specialized cells are more efficient than nonspecialized cells. thank you, goodnight.
Do multicellular organisms differ from unicellur organisms?
A colonial organism is a collection of one-celled organisms living together. The difference between a multicellular organism and a colonial organism is that individual organisms from a colony can, if separated, survive on their own, while cells from a multicellular life-form (e.g., cells from a brain) cannot. Multicellular organisms consist of differentiated cells that perform special tasks. The entire organism requires all the different types of cells to be present, and the individual cells can not survive without being in the organism
Why is division of labor important in a multicellular organism?
In multicellular organisms, cell might have seperate jobs or tasks.In a unicellular organisms,the only cell present will have to complete all tasks necessary for survival.With multicelled organisms ,it allows for certain cells to specialize in their function and divide the labour between multiple different cell groups.
How does multicellular maintain homeostasis?
The cells of multicellular organisms become specialized for particular tasks and communicate with one another to maintain homeostasis. Specialized cells in multicellular organisms are organized into groups. A tissue is a group of similar cells that performs a particular function.
Is a guinea pig a unicellular or multicellular?
As mammals elephants are multicellular. There is millions of different cells required to perform daily tasks.
How does a multicellular organism maintain homeostasis?
The cells of multicellular organisms become specialized for particular tasks and communicate with one another to maintain homeostasis. Specialized cells in multicellular organisms are organized into groups. A tissue is a group of similar cells that performs a particular function.
