In the course of evolution of theeukaryotic cell, the ability to store newly synthesized moleculesis associated with: a) the nucleus of prokaryotes, b) vesicles thatcontain enzymes that perform dehydration synthesis, c) lysosomes,d) the nucleoid area of the cytoplasm. e) proteins produced outsideof the Endoplasmic reticulum.  

Answer B why?

For eukaryote cells to evolve intonew types of eukaryotic organism, which of the following would oneexpect to occur? a) All the cells are identical b) The endoplasmicreticulum is not involved. c) These specialized cells activate onlythe genes in their nucleoid area. d) Cells must be getting newgenetic mutations and more DNA e) none of these are true.

answer D why?

In the evolution of the eukaryoticcell, these cells have key changes that include which of thefollowing:

a) These cells reproduce by copyingtheir DNA perfectly each generation.

b) They have their DNA in thenucleoid area.

c) have adapted the mesosomemembrane system of the prokaryote to form a nucleus and anendoplasmic reticulum.

d) each new type of new eukaryotecell has its mRNA unchanged from its original mRNA,

e) none of these are true.

Most of the carbon dioxide we exhaleis produced in:

A) glycolysis.

B) photosynthesis in thechloroplasts,

C) formation of pyruvate duringglycolysis,

D) the mitochondrion during theKrebs cycle,

E) none of these.

Which is true of Prokaryotecells?

B) They contain membrane-boundedcompartments or organelles.

C) A true nucleus contains the DNAin the form of chromosomes

D) They all contain mitochondria

E) They contain many organelles inthe cytoplasm

In both Prokaryotes and Eukaryotes,which of the following structures can cross cell membranes usingthe same protein channels as water?

A) mRNA,

B) triglycerides,

C) large, non-polar molecules,

D) DNA,

E) gases (CO₂ andO₂) and small ions.

plz explain the answer , Thankyou
