A cell wall.

The cell wall is on the outside. 
Only plants have chloroplasts but they are inside the cell.
All cells have cytoplasm (think of this as the fluid inside the cell).

mario62 [17]

Answer:

The plant cell wall is strengthened by the molecular structure of cellulose. Cellulose is made up of ß-glucose arranged upside down, this arrangement aided hydrogen bonds between the hydrogen ions of the  hydroxyl group and oxygen of the of the ring   of same  betta -glucose.

The aggregation of the hydrogen  bonds give bundles of  strong tensile  strength of cellulose called the  microfibrils (of 60-70 celluose molecules).They are  held together in bundled called fibers.T<u>hese is the source of  plant cell walls  strength. </u>

Collagen is the main extracellur matrix (EM) in animal cells.It is a glycoprotein made up of 25%of body protein of animals.Each collagen molecule is made of helix shaped ,three polypeptide chains, wound around each other to form<u> triple helix.</u>The bonds  holding helix together are hydrogen and covalent bonds.

Each triple helix is attached to adjacent collagen molecule, parallel  to it. The covalent bonds formed a cross link which held  the collagen molecules together forming FIBRILS.  This gives flexibility to collagen, while maitaing strong tensile strength. This is what is responsible for the structural strength of cell membrane .

.The  EM,is  futher reinforced with  carbohydrate molecules(proteoglycans) which<u> aided in water movements by  osmosis following  sodium movements into the matrix.</u>

Pathogens are transmitted in only two ways: by direct contact and by vectors.
Marina86 [1]

Answer: False

Explanation:

Pathogens can be transmitted in many ways. It can spread by direct contact, indirect contact, or by vectors.

The mode of transmission can be skin contact, airborne particles, touching a surface, bodily fluids, touched by an infected person.

The mode of transmission can be vector that carries disease and helps in disease transmission.

So, the pathogens can be transmitted by direct contact, indirect contact or by vectors and by many more ways.

V125BC [204]

Cellulose, chitin, and peptidoglycan are all considered as carbohydrates. Now in the molecular level of these carbohydrates, structural polysaccharides exist as sets of long, parallel strands that are linked to one another. Due to this arrangement, pulling and pushing forces are being withstand.

What happens in the postsynaptic neuron when excitatory neurotransmitters bind to receptors?
zubka84 [21]

Answer:

it causes the depolarization of the target cell

Explanation:

Glutamate is an excitatory amino acid neurotransmitter that binds to specific receptors on the surface of target cells and thus causes its depolarization. During glutamate-mediated depolarization, the difference in charge inside and outside the cell is lost due to the entry of sodium and calcium positive ions into the postsynaptic cell (neuron) through specific ion channels. Moreover, glutamate binding also leads to the exit of potassium ions from the cell, thereby resulting in excitation. Through this mechanism, glutamate regulates many signaling pathways, such as those involved in memory, learning, emotions, cognition, motor control, etc.
