Answer:

Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Explanation:

dang it.

Answer:

The Laura tried to grow micro-organisms in culture broth medium in Petri-plates but the microbial growth was not observed even on the fourth day of culture which could be due to:

1. Laura could have not provided the correct broth medium maintaining the with pH and salt concentrations.

2. Microorganisms did not get optimal growth conditions.

3. The bacterial source could have died after the collection which could have lysed after their death and thus no longer visible.

Why are frogs said to have “two lives” ?

Vladimir79 [104]

Answer:

One because they are amphibians
two because amphibian means two lives
third because they live on land and sea
Fourth because they live longer (I think)

Explanation:

Frogs begin their lives in the water as eggs and then tadpoles and when they are fully developed they live on land.

According to the Endosymbiotic Theory, infoldings in the cell membrane of an ancestral prokaryotic cell gave rise to endomembran

Ad libitum [116K]

Explanation:

False: C) The ER provides separate microenvironments for each of the modifications that must take place to proteins.

The golgi apparatus comprised of several components called cisternae, these function as different microenvironments, where further modification proteins and lipids into functional biomolecules occurs.

During protein synthesis, transcription occurs in the nucleus, followed by translation within ribosomes, the newly synthesized proteins enter endoplasmic reticulum where they undergo folding and modification. Within the golgi body, the proteins are tagged and parceled into lysosomes for export.

Further Explanation:

The endoplasmic reticulum is a membrane system within the cytoplasm that extends from the outer nuclear membrane. Apart from increasing the surface area within the cell, this continuous system also carries out protein folding, synthesis and transport. In the endoplasmic reticulum or ER, some sections called the smooth ER, do not contain ribosomes, and may contain lipids, enzymes, and other proteins. Other sections bound to ribosomes, are called the rough Er. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen. The proteins undergo major modifications and are packed into vesicles.

Golgi bodies are flat, disk-like membranous regions. Proteins traverse the organelle by first having their vesicles bind to the cis face or receiving end. Like a post office, the golgi complex, or golgi body recognizes specific signal sequences, targets and further modifies and packages these compounds into lysosomes for delivery to their final destination. Proteins here undergo peptide processing and glycosylation
