The Unit 'Understanding organisms' is not found here, but an organism is a biological system composed of cells.

<h3>What is an organism?</h3>

An organism is a living entity that is defined by the presence of cells, which are the basic structural unit of life.

Organisms have the ability to respond to external stimuli, perform metabolic activities and exhibit a internal state of equilibrium (homeostasis).

Organisms can be composed of single cells (e.g., bacteria, protists) or many cells (e.g., plants and animals).

In conclusion, the Unit 'Understanding organisms' is not found here, but an organism is a biological system composed of cells.

zhannawk [14.2K]

Answer : The correct answer is - C) The left and right sides of the body are symmetrical.


Explanation -

Bilateral symmetry is a body plan of a life form, according to which the organism can be divided into two equal halves (right and left half) only when cut through central axis/midline of the body (also called saggital plane).

Example of bilaterally symmetrical organisms- insects like coackroach, butterfly.

Thus, option C) is the right answer.

Which of the following is NOT a capillary transport mechanism?
Zanzabum

Answer:

Bulk flow

Explanation:

Generally when there is  mass movements of molecules of the fluids from a high pressure gradients to low pressure gradients; that is down the concentration gradients, the process is called Bulk flow. In relation to cells, it is  the exchange of material between cells  through the pores of the adjoining  cells. In xylem , water and minerals flow from high pressure roots to the leaves, and phloem transport food substances from the  leaves the sources at high pressure to other parts of the plants.

The capillary transport mechanisms involves the movements of fluids, ions across the fenestration of the capillaries due to  the hydostatic  pressure of the fluid from the high pressure to the low pressure cellular environments.This is common in the  glomerulus of the kidney, intestine, and some endocrine glands.

The single wall endothelial lining of  capillaries forms continuous wall which allows passage of ions and fluids while restricting movements of large molecules. Generally the high pressure  from the hydrostatic pressure forces these materials across the walls.

Simple diffusion  which follows concentration  gradient across membranes ensures distribution of substances across the walls for fast uptake by the cells.

The movement of Macromolecules  across capillary wall is called vesicular transport.

Thus Bulk flow is odd.
