Fertilisation in kangaroos is an internal process, not external. This is the case with all mammals.
External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.
It is the outer layer of protection of the Cell. It controls what goes in and out of the Cell. It contains lipids, proteins, and phospholipids. It is very important because it protects the Cell from the environment.It is called a neurolemma if it is around a nerve cell, and a sarcolemma if it is around a muscle cell.cell mem·branenounthe semipermeable membrane surrounding the cytoplasm of a cell.hope this helps!
The cell membrane is selectively premeable. It regulates what comes and goes from the cell. Homeostasis- The ability of living things to maintain steady state of operation the membrane helps in this activity. -Ally :D
Cells mutate rapidly and in the end, it develops into cancer.
to control what goes in and out of a cell
Well, let's see if my Communication degree can be put to use. Internal communication is between management and employees, marketing, research, field operations and all the many departments in a company. Usually housed within the Human Rssources department it is to insure that information goes out in an accurate and timely manner. External communication is between the company and the public in general, suppliers, customers, stock holders and other stake holders to inform and advertise the public face of the company as well as for fiduciary responsibilities. A break down in either internal or external communication will eventually spell disaster when and if a disastrous event were to befall the company. An example would be, British Petroleum is still putting out image ads talking about the efforts and success stories after the cleanup of the oil spill in the Gulf of Mexico. This is an example of an external communication.
The diameter is the measurement of a line that goes right through a circle, through the centre point. In cases where we have a ring or some other such object with multiple circles, we would have an external diameter and an internal diameter. The internal diameter is the diameter of the inner circle. The external diameter is the diameter of the outer circle.
Internal. A virgin queen goes out on a mating flight about 5 days after she hatches and mates with several drones (male bees) which fertilizes all the eggs that she produces throughout her life. She never has to mate again.
If Rin = Rout, then the voltage at the output of the device goes down to half of the value that the circuit has without the external resistance. Scroll down to related links and look at "Interconnection of two audio units".
they have external fertilization , PS i learned it in science :P zz this is all wrong...it does NOT use exernal fertilization...external fertilazation is for fish and stuf,but internal is for humans and mamals.
yes and/or no everything that goes IN a computer is internal, external is outside the case you could get an external graphics card but that would make your laptop more like a desktop, you should get internal, and yes, you need to open it up. if you don't know what to do, take it to a PC store and let them do it.
Cell membreneA layer that controls what enters and what leaves the cell. Or a protective covering enclosing the entire cell.(controls substances going in and out of the cell.)
An Internal Frame Backpack, through the top, like clothes. It goes all the way to the bottom, or you could use an External Frame, and tie it to the bottom.
Internal cell regulators are proteins that respond to changes within a cell.For example, a normal cell will not enter the mitosis stage of cell division till the entire DNA is replicated. This check is regulated by a protein within the cell. This protein is the internal cell regulator.
A customer is some person or organization that uses an output from a different person or organization. Customers are defined as internal and external to an organization. External customers are most common in sales where a company sells a product to a customer. Internal customers are persons or departments who rely on output from another department of the same organization to accomplish their own function. A typical example of an external customer is a grocery shopper who goes to a market to buy goods. This person is from outside the organization of the market. In the supermarket example, an internal customer is the manager who relies on information from accounting to make decisions, or the stock person who needs to receive materials from the warehouse in order to put goods on the shelf.
