If a cell membrane were composed of only a phospholipid bilayer what properties would it have

Brut [27]3 years ago

<span>Life aint a game 10 is correct. Also the cell would be unable to respond to its environment as this relys on molecules binding to proteins on the cell surface. For the same reason most mechanism of cell signaling not work because the initial step is for a molecule to bind to a receptor. Also no proteins = no receptors = no immune response in white blood cells because this also requires receptors to recognise foreign material.</span>

The table shiws data for two groups of plants, one grown with fertilizer and the other without fertilizer​
Yakvenalex [24]

Answer:

33.5

Explanation:

the mean height is the average. Simply add up the height of all the plants with fertilizer and divide by 5 (Being the amount of plants with fertilizer)

30.5+32.1+40.6+30.5+33.8 = 167.5

167.5/5 = 33.5

AH(average height)= 33.5

How does the white-tailed deer overpopulation affect the ecosystem
nalin [4]
Answer: Too many deer in a given area results in overgrazing and the eventual loss of brush and shrubs in forested areas. Loss of undergrowth means no place for small animals and birds to shelter and nest. The result is the disappearance of many native species that no longer have access to the habitat they need.

A human body cell has 46 chromosomes which diagram Represents Mitosis in a human body cell
Scrat [10]

Answer:

The diagram which shows the formation of two daughter cells is mitosis.

A human body cell has 46 chromosomes when mitosis in a human body cell occurs, the parent cell divides into two daughter cells which has the exact number of chromosome i. e. 46 in each daughter cell. When replication of chromosome occurs, two identical copies of chromosomes are formed.

An actin-binding protein called cofilin binds preferentially to ADP-containing actin filaments rather than ATP-containing actin
Phantasy [73]

Answer:

Cofilin binds to older actin filaments

Explanation:

Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.
