Answer:

<em>Diffusion</em>:

Substances, such as water, ions, and molecules needed for cellular processes, can enter and leave cells by a passive process such as diffusion.Diffusion is a type of substance movement that requires no energy to be expended for the substance to move. Simple diffusion occurs when there is no obstacle to the substance so it can diffuse freely.

<em>Osmosis</em>:

Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute (lower concentration of solvent).There are three types of solutions that's determine osmosis-

1) hypotonic solution: in this case the solvent is less and the solution is more(dilute solution).More water is there outside the cell than inside the ell, so the water moves into the cell which causes the cell to swell up

2)hypertonic solution: in this case there is more solute than solvent(concentrated). More water is there inside the cell than outside the cell, so more water will leave the cell than it enters as a result the cell will shrink.

3) Isotonic solution: the amount of water inside the cell is equal to water outside the cell as a result the cell will neither shrink not swell.

<em>Examples of diffusion</em>:

Oxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood. carbon dioxide moves down a concentration gradient from the blood to the air in the alveoli.

<em>Examples of osmosis:</em>

Osmosis occurs to recover water from waste material. Kidney dialysis is an example of osmosis. In this process, the dialyzer removes waste products from a patient's blood through a dialyzing membrane(acts as a semi-permeable membrane) and passes them into the dialysis solution tank.

Tcecarenko [31]

Answer:

1.The group of organisms with cells which contain of nucleus and other membrane bound organelles are called Eukaryotes. These organisms have their DNA arranged in the chromosomes, bounded by histones proteins. They have diversity of forms, thus they can be colonial, unicellular or multicellular in forms. Their cells reproduced by mitosis and meiosis for gamete formation.  

Reproduction can be sexual and asexual. Their ribosomes are found in the cytosol, and they are larger than that in prokaryotes, but ribosomes in chloroplast and mitochondria are similar as that in the Prokaryotes (70s). Plants and complex animal cells are examples.  

Group of unicellular organisms which lack membrane bound nucleus, and other organelles, are called Prokaryotes. Their two domains are the bacteria and archaea. They reproduce asexually only, by fusion of gametes. Due to lack of membrane bound organelles, their water soluble components and cellular inclusions (metabolites and DNA) are found in the cytoplasm bounded by the cell membrane.  

<u>When viewed under microscope. Prokaryotes are similar to Eukaryotes as follows. </u>

What drives motility in sporozoa?
muminat

Sporozoa are non motile organisms.

<h3>What do you mean by sporozoa and why they are non motile?</h3>

Sporozoa are  parasitic non motile protozoa that  have a complex life cycle usually involving both sexual and asexual generation often in different hosts and includes important pathogens. Sporozoans do not have flagella or cillia for locomotion . They depend on twisting and bending on move.

Sporozoa do not have flagella or cillia for locomotion. So, they are non motile .

How does a convection current transport energy around the globe
Helen [10]
The ocean around the globe gets heated up due to the heat around the sun. This hot water is then passed through to the colder regions of the globe by the method of convection. This is a continuous process.

Which is the MOST accurate description about how the different types of feed mechanisms work.
marishachu [46]

Answer:

D

Explanation:

Positive feedback loops are rarer than negative ones because of homeostasis, but they do occur. Negative feedback loops return to the set point in reverse, and positive feedback loops amplify a departure from the set point​.
