Answer: Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. ... Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
Explanation:
Answer:
B) tissue
Explanation:
The evolution of life on Earth shows that life originated when a structure which contained all the molecules called molecules of life with suitable conditions to survive was formed. The structure was surrounded by the plasma membrane and is known as the cell.
During the evolution of cells, the cells aggregated together to perform a higher and complex function which happened when the group of the cell was programmed to perform the same function called tissue. Thus, the tissue is the level of organization which can perform a particular function by a group of cells.
Thus, the tissue is the correct answer.
Answer:
towards Andrew
Explanation:
The direction in which the desk will move would be towards Andrew.
This is a simple case of resultant force. If both Michael and Andrew had pushed the desk together across the classroom, the resultant force would have been the addition of their individual's applied forces - neglecting any other extraneous forces. However, since they decided to push against each other, the resultant force would the subtraction of their individual forces and the desk will move towards the person with who applied the lower forces out of the two.
<em>Since Michael applied force was 30 N and that of Andrew was 28 N, the resultant force would therefore be 2 N in the direction of Andrew. In other words, </em><em>the desk would move towards Andrew.</em>
