What is the function of a cell's selectively permeable plasma membrane

The plasma membrane is a semi-permeable membrane that allows the movement of a molecule from inside to outside of the cell and vice versa.

Further Explanation:

The plasma membrane is mainly composed of cholesterol, protein, and phospholipids. They move easily in the membrane and maintain the fluid nature of a membrane. The main component of the plasma membrane is phospholipids that are made up of fatty acid, phosphate, and glycerol. These phospholipids make two layers of phospholipids that are mainly known as the lipid bilayer. This bilayer makes the plasma membrane semi-permeable and helps in the transport of molecules from inside to outside and vice versa.

Other components of the lipid bilayer are carbohydrates and protein. They also play a major role in the plasma membrane because they help in cell signaling. Glycolipids are present on the outer side of the cell membrane. The membrane of the cell also plays a significant role in protecting the cell from the exterior environment and acts as a barrier.

The function of the semi permeable membrane is to allow substances to diffuse (transport) across it, because its only semi permeable the substance are able to cross. If it was a non permeable membrane it wouldn't allow the transport of substances.

There are 3 main categories of environmental problems that have come about because of the population growth. What are they and e

kakasveta [241]

Answer:

i)declination of resources

ii) air, water and land pollution

iii) global warming

Explanation:

As we all know that population is increasing day by day, all the country of the world are facing rapid population growth.we are facing many problems, the population growth is increasing day by day, the more the population, the more resources we need due to this, the resources is decreasing day by day, we need more resources as there is more population, the increasing population makes more pollution due to this global warming is increasing. We know that there is no more more resources in our world if the resources is finished in this day the future generation will not be able to survive and will not be able to use such resources.we should prevent such resources for future generation also the future generation should get the chance to use such resources .the pollution is increasing day by day .we should control it .the main thing is that we should control the rapid population growth population growth should be controlled due to this global warming is increasing which is very dangerous leading to the declination of ozone layer due to which the harmful rays of sun may enter the earth which may cause various problems in us and cause various diseases due to which we may die.the main thing is that we should stop the population growth, we should conduct public awareness programmes and many more programmes to educate people. Population growth also creates deforestation as the number of people are increasing day by day they need more place to live ,they need more Land due to this they cut down the trees of forest and used to make houses there due to which deforestation takes place. we all know that deforestation is the process of cutting down trees. so the tree should not be cut down as it is the source of oxygen for all creatures living in this whole world and the main thing is that we should provide education to the children and the youth and many more. if we are educated we can stop such population growth. so the main thing is that we should stop population growth by giving education. Education is the only one way to stop such population growth.

Would a bacterial cell undergo mitosis in the same way as a eukaryotic cell? Why or why not?

nikklg [1K]

Unlike eukaryotes, prokaryotes (which include bacteria) undergo a type of cell division known as binary fission. In some respects, this process is similar to mitosis; it requires replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm.

Without undergoing any changes itself, the _____ makes changes to the ______.

BigorU [14]

Without undergoing any changes itself, the enzyme makes changes to the substrate.

<h3>What is an enzyme?</h3>

An enzyme is a biological catalyst that acts by lowering the activation energy in a chemical reaction.

In a chemical reaction, an enzyme binds to a substrate to convert it to one or more products.

In conclusion, without undergoing any changes itself, the enzyme makes changes to the substrate.
