What Best describes a difference between Prokaryotic cells and eukaryotic cells?

Answers

Answer 1

Answer:

Eukaryotic cells contain organelles that are enclosed in membranes. ... Prokaryotic cells contain a nucleus that is enclosed in a membrane

Answer 2
1. A Prokaryotic cell is surrounded by a single membrane layer but In the case of Eukaryotic, there are two surroundings 1. Plasma membrane 2. Nuclear membrane.

2. In the case of prokaryotic cells, the cell wall is made up of Carbohydrates, lipids, protein and certain amino acids whereas The eukaryotic cell wall is made up of chitin and cellulose.

3. Respiratory enzymes are present on the cell membrane in prokaryotic cells whereas Respiratory enzymes are absent on the cell membrane in Eukaryotic cells

4. Thylakoids present in the cytoplasm in prokaryotic cells whereas Thylakoids occur within the chloroplast in eukaryotic cells

5. SAP Vacuoles are present in prokaryotic cells but SAP vacuoles are commonly present in Eukaryotic cells

6. 70s ribosome are present free in the cytoplasm or attached to mRNA in prokaryotic cells whereas 80s ribosomes are present either free or bound to the endoplasmic reticulum and nuclear Envelope for mRNA

7. Endocytosis and exocytosis do not occur in prokaryotic cells but Endocytosis and exocytosis takes place in many protists and in animals

8. The nucleus is absent in prokaryotic cells. nuclear material lies in the cytoplasm and is called a nucleoid, contains a single chromosome whereas Well developed nucleus found in Eukaryotic cells which surrounds why nuclear membrane nucleus contains two or more chromosomes

9. Fertilization, gamete formation and meiosis do not occur in prokaryotic cells whereas Fertilization, gamete formation and meiosis are well developed in Eukaryotic cells.

10. Prokaryotic cells are haploid whereas Eukaryotic cells are of both types, diploid and haploid

11. Nuclear envelope or nuclear membrane is absent in prokaryotic cells Well developed nuclear membrane or nuclear envelope surrounds the nuclear material

12. The nucleolus is absent in prokaryotic cells whereas One or more nucleolus is present within the nucleus

13. Circular DNA is present without associated proteins Nuclear DNA is associated with proteins in prokaryotic cells but It is linear while extranuclear DNA is present without proteins in Eukaryotic cells

14. If present Flagella are simple, consist of a single fibril. Flagella are formed of a protein called flagellin. but Flagella are complex in structure, 9+2 pattern of microtubules formed of the protein called tubulin in Eukaryotic cells if present.

15. Plasmids and pili are present in many prokaryotic cells whereas Plasmids and pili are absent in eukaryotic cells.

16. Most prokaryotes are reproduced by means of asexual reproduction Most but Eukaryotes are reproduced by means of asexual reproduction.

How does water behave when it freezes?

Answers

Answer:

During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds...Thus water expands as it freezes, and ice floats atop water.

B. Is what the scientists manipulate in the experiment.

Explanation:

The Independent variable is not dependent, or doesn't rely, on another variable in the experiment. So, it would make the most sense that they would manipulate the Independent so that they can watch and see how the dependent variable reacts to the manipulation, or the change, in the independent variable.

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case? (3 points)



a) Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.


b) The two sides of a cell membrane face different environments and carry out different functions.


c) The molecular composition of the inner and outer layers of the cell membrane is determined by genes.


d) Proteins only function on the cytoplasmic side of the cell membrane, which results in asymmetry across the membrane.

Answers

Answer:

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.

Explanation:

PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .

PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.

On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.

LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.

The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.

Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.

CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.

Hence , the correct option is B.
