Which of the following plant cell structures could not be seen when using the 10X objective of the compound microscope? A) Nucleus 2) Cell wall 3) Cytoplasm 4) Endoplasmic Reticulum

Endoplasmic Reticulum

ER Golgi apparatus, because it packages proteins received from the ER cytoplasm 


The Golgi body are the ones that slightly alter, organize and prepare so-called parcels to be delivered for all the organelles in the cell. They receive these packages mainly in the rough endoplasmic reticulum. These packages that set out by Golgi body are macromolecules that used and synthesized by cells in many operations. If ER is absent then it would only mean that Golgi body would have no use other than simply lysosomes but these macromolecules plays a dynamic role in many organelles –nutrients, ATP and cell metabolism. It'll have a ripple effect if ER is absent in the cell.

The paper clip, which is denser than water, floats on the surface because of water's surface tension. Surface tension is a property of water that is the result of polar water molecules sticking together or water's property of A) adhesion. B) cohesion. C) buoyancy. D) capillary action.

The answer is cohesion. The high surface tension helps the paper clip (with much higher density) float on water. The property of a liquid that allows it to resist an external force, due to cohesive nature of its molecules. Cohesion refers to the attraction of molecules for molecules of the same kind. Water molecules have strong cohesive forces due to their ability to form hydrogen bond with each other.

Which factor does not play a role in runoff the amount of rain or snow plants gravity solar radiation

Infiltration is the process by which rainwater becomes groundwater. In the water cycle, which involves primarily; evaporation, condensation and precipitation. Henceforth, after precipitation comes infiltration in the land areas leaving the rainwater aggregated in a single location which accumulates over time. Then this process is followed by runoff and subsurface flow by which water flows through other bodies of water, either in river, sea or ocean, even lake. Other rainwaters that has segregated and wasn’t able to transport itself stays in the process of infiltration, thus groundwater.

Thus, solar radiation doesn't play a role in runoff or infiltration.

List 3 examples of a selectively permeable material or item. Explain where it is found or used and why a selectively permeable item is needed

Answer;
Examples of selectively permeable materials or items are; 
1. Vacuum filter- it traps dust but allows air through
2. Coffee filter- allows water to pass through, but does not allow the coffee grounds.
3. Colander -used to strain liquid food from foods. it drains water but is not permeable to larger food particles.

Explanation;
Selective permeability means that a material or a substance allows the passage of some molecules or ions and other materials to pass through it, and inhibits the passage of others. 
For example a cell membrane is semi-permeable and thus regulates the transport of materials such that some particles pass through while others can not cross. A semi-permeable membrane allows selective movement of materials, it acts like a filter that allows particles to pass or not according to their size, solubility, electrical charge, or other chemical and physical properties.

What would happen if you were given pure water in an IV?

The question is what would happen if you are given pure water in an IV. The answer is, the pure water will disrupt the osmotic balance of the body. Saline solutions are usually used in IV, this is because, there is a need to maintaint the osmotic pressure between the body cells and body fluids. Cell membranes are selectively permeable, infusing the body system with pure water will make pure water to rush into cells, dilute the contents and make the cells to swell up.

What is a difference between starch and glycogen? A.) Starch stores energy, and glycogen provides structural support. B.) Starch is found in plants, and glycogen is found in animals. C.) Starch is composed of fructose, and glycogen is composed of glucose. D.) Starch is a monomer, and glycogen is a polymer.

The right answer is B.

Starch is, along with cellulose, the most common polysaccharide in the plant world. It constitutes the essential energy reserves of plants and is a component of the diet of humans. It is part of the group of slow sugars. Its consumption is particularly recommended to those who practice a sport.

Glycogen, which is a polysaccharide, is the form in which carbohydrates are stored in the body (animals and fungi). Glycogen is broken down into glucose molecules when the body needs energy.

Which of the following factors would have the least effect on the carrying capacity of an ecosystem? a. the total number of organisms b. the available water supply c. the available food supply d. competitive exclusion

Correct answer: D) Competitive exclusion

Carrying capacity of an ecosystem may be defined as the total number of organism it can support. Biotic and abiotic factors such as available space, water, food and shelter  act as a limiting factor, which determine how many organism can live within a ecosystem.

The competitive exclusion principle states that two species that compete for same resources cannot stably coexist.

One among the two competitor will always have slight advantage over the other, it leads to extinction of other competitor or lead to an evolutionary shift of the inferior one to a different ecological niche. Therefore, competitive exclusion have least effect on the carrying capacity of an ecosystem.
