Ribosomes are small particles that consist of RNA and associated with proteins that function to synthesize proteins. Proteins are needed for important cellular functions such as repairing damage or directing chemical processes. The nucleus is important for controlling gene expression and meditating the replication of DNA during the cell cycle. Hope this helps ;)
I’m not too sure but I think it’s the last one
Which statement is correct about plant-like and fungus-like protists.
Question 4 options:
A) Plant-like protists are all parasitic, while fungi-like protists are not.
<u>
B) Plant-like protists are unicellular, while fungus-like protists are multi cellular.
</u>
C) Plant like protists are usually autotrophs, while fungus-like protists are heterotrophs.
D) Plant-like protists live on land, while fungus-like protists live on land and in water.
Answer:
Endoplasmic reticulum
Explanation:
The endoplasmic reticulum is part of the endomembrane system inside almost all eukaryotic cells.
The membrane is continuous with the nuclear membrane. The endoplasmic reticulum is very important for modifying proteins and transporting them in vesicles to the Golgi body for further processing and transport to their final destinations.
The endoplasmic reticulum can be rough (have ribosomes attached) or smooth (lack ribosomes).
The process responsible for the movement of substance A into the cell will be active transport.
<h3>What is active transport?</h3>
It is a kind of cellular transportation of molecules against their concentration gradients through the use of energy.
Active transports are different from passive transports. The latter has to do with the cellular transportation of molecules in and out of the cell without involving the use of energy.
In the diagram, there is more concentration of substance A inside the cell than the outside. Thus, moving substance A into the cell will be a movement against its concentration gradient.
The movement of substances against concentration gradients always requires energy, usually in the form of ATP - active transport.
