what would you if cell membrane became impermeable instead of selectively permeable could cell remain alive
natali 33 [55]
If a cell membrane became impermeable, instead of selectively permeable, the cell would not remain alive, though certain organisms would be able to stay alive longer than others. This is because the cell membrane allows essential molecules and substances such as oxygen into the cell, while allowing harmful substances, like waste, out of the cell.

Why is cytokinesis an important part of the cell division? how can cytokinesis help us?
Sliva [168]

Answer:

1. Cytokinesis represents the major reproductive procedure of unicellular organisms, and it occurs in the process of embryonic development and tissue growth and repair of higher plants and animals.

2. Cytokinesis performs an essential process to separate the cell in half and ensure that one nucleus ends up in each daughter cell. Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase.

"DNA denatures at a higher temperature than does protein, yet its structure depends on relatively weak hydrogen bonds. Why the d
Reika [66]

The option are not given and the options are:

Proteins are denatured by breaking covalent bonds.

Linear molecules like DNA are inherently stable.  

Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

The statement is incorrect; it actually takes far more energy to denature proteins than it does to denature DNA.

Answer:

The correct answer is- Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.

Explanation:

Proteins become denatured when it looses its three-dimensional structure. Disulfide bond and hydrogen helps in stabilizing the three-dimensional structure of proteins and if these bonds break due to any factor protein lost its structure and function.

DNA is made up of a large amount of hydrogen bond because in AT base-pairing two hydrogen bonds are required and in GC base pairing three hydrogen bonds are required. Therefore it can be concluded that as more hydrogen bonds stabilizes DNA than protein its melting temperature is higher than protein.
