Prokaryotes are identified with bacteria: most live as single-cell organisms but some bacteria associate in a chain. Prokaryotes have their DNA in the cytoplasm of the cell. Eukaryotes ("Eu" for true) have a nucleus, a compartment separated from the rest of the cellular content, which contains the DNA.
In both of eucaryotic an procaryotic cell, you can find DNA, all kinds of RNA, Cytoplasm, ribosomes, and a cell membrane,
In procaryotic cell only you can find: a cell wall (located outside the cell membrane), you may find also pili, capsids, plasmids, and flagella.
In a eucaryotic cell only, you can find Nucleus (which contain the DNA), mitochondria, endoplasmic reticulum,
Answer:
Explanation:
Which of the four types of macromolecules, and in which proportions, are present in this food sample?
The vesicle is a type of skin eruption. Vesicles are cell organelles that are made out of a lipid bilayer. You can consider vesicles cell envelopes that are utilized to transport materials starting with one place then onto the next. Vesicles likewise work in digestion and catalyst stockpiling also. This graph demonstrates the general structure of a straightforward vesicle.
Answer:
The sound will reach my ear in a shorter time in Scenario 1.
The speed of sound waves in solids is faster than it is in gases.
Explanation:
The sound which is produce due to hitting of metal bar with a drumstick reaches to the ears in short time because sound is a longitudinal wave which requires or needs medium for its propagation from one place to another and in solids the particles of medium are close to each other as compared to air so the sound travels faster in solid materials as compared liquid and gases and takes less time to reach my ears.
