The answer to this question would be: <span>b.electromagnetic or weak nuclear

The electromagnetic force can be repulsive or attractive because it was influenced by the magnetic charge. The same charge (positive with positive) will be repulsive but different charge will be attractive(negative and negative). The gravitational force will always be attractive, not repulsive.
Weak nuclear can do both like electromagnetic force.
transgenic organism has a specific desirable gene transplanted to another organism. so the first step is to identify the desirable gene. ans is D. Find a gene in one species that would be useful if added to the DNA of another species.
As DNA replication begins the DNA molecule is broken apart into two complementary strands. DNA replication is the process by which DNA makes a copy of itself during cell division. The process occurs in all living and is the basis for biological inheritance. The process starts with the separation of DNA strands in the double helix. Then replication for is formed followed by the binding of bases to each strand. Then the last step is termination of the Replication process
The correct option is D.
The Endangered Specie Act was enacted in 1973. It is an environmental law which provides for the conservation of species that are endangered or threatened and the preservation of the ecosystem in which they live. The law prohibit the catching and killing of endangered species.
