A mechanical watch is an example of what?
Compound Machine
What is the difference between a mechanical mechanism and a non-mechanical mechanism?
the difference between a mechanical and non-mechanical system is that non-mechanial systems is a procedure/process designed to perform a task along with people involved (example, the school system is a non-mechanical system because it involes students, teachers, desk, textbooks etc)a mechanical system is group of physical parts that interact with each other and function as a whole in order to finish the task (example, the TTC system involes the buses, subways, etc)
Why are some machines built with mechanical disadvantage?
For flexibility or movement. For example most of our bodies joints have a mechanical disadvantage for the simple reason we gain range of motion and flexibility.
Give two example of universal coupling application in mechanical engineering?
1.Drive shaft of a vehicle 2.Automotive steering linkages
What is the motor that converts thermal energy to mechanical energy?
The generic term is "heat engine". Most engines - for example, car engines - are in this category.
A reproductive barrier that prevents species from mating is an example of?
a prezygotic barrier
What is an example of a postzygotic reproductive barrier?
A postzygotic reproductive barrier occurs after fertilization. One example is hybrid inviability, where the offspring of two different species have genetic incompatibilities that prevent them from developing or surviving normally.
What is a reproductive barrier in which the zygote dies before birth?
postzygotic barrier
What is an example of mechanical barrier that the body uses for protection?
The largest organ in the human body, our skin, is effectually, an excellent mechanical barrier. There are of course, some chemical and bacterial (normal flora) factors that play a part, but its mechanical function is its largest asset for sure. A break in the integrity of this mechanical barrier (i.e. an abrasion, laceration, puncture, incision, etc) provides an open door and an excellent opportunity for foreign bacteria and viruses to invade and potentially infect the host.
Which one of the following is an example of a postzygotic reproductive barrier A Hybid sterility B habitat isolation C Gamete isolation?
A Hybrid sterility is an example of a postzygotic reproductive barrier. This occurs when the offspring of two species are sterile and cannot produce viable offspring of their own. It is a mechanism that prevents gene flow between species after mating has occurred.
The type of reproductive barrier that occurs when two species mate but produce sterile hybrids is referred to as?
a post-zygotic barrier
Example of post-zygotic barrier?
Post-zygotic barriers are reproductive barriers that occur after fertilization, such as hybrid inviability or hybrid sterility. An example of a post-zygotic barrier is when a hybrid offspring fails to develop properly or is unable to reproduce, reducing the fitness of the hybrid offspring.
The type of reproductive barrier that occurs when two species mate but fail to produce fertile hybrids is referred to as?
The type of reproductive barrier you are referring to is called "hybrid inviability" or "hybrid infertility." It occurs when the offspring of two different species are unable to reproduce themselves, often due to genetic incompatibility between the parents.
What is an example of mechanical refrigeration?
example of mechanical refrigeration
What are barrier method of contraception?
A barrier method means there is a physical device to prevent sperm from entering the woman's reproductive tract.Birth Control Pills, IUD, sterilization, withdrawal, rhythm, are not barrier methods.Male or female condom, sponge, cervical cap, diaphragm are all barrier methods.
Mechanism for when anatomical differences prevent mating?
Mechanical reproductive isolating mechanism
How many types of barriers of communication are there?
There are many types of barriers of communication for example; language barrier, physical barrier, emotional barrier, listening barrier, cultural barrier, gender barrier etc
