One species eventually changes into something completely different over the course of millions of years. This can be described using the evolution theory. The evolutionary process of species shows how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the parent population. Hence one species is changed into another over o period of time. Speciation is an evolutionary process by which a new species comes into being.
This theory of evolution was proposed by Charles Darwin.
Answer:
The passing of genetic information from one generation to the next
Explanation:
<h2>Option(A) is Right Answer</h2>
Explanation:
(a) lobules is right answer
- <em>The spermatozoa from the rete testis, </em>at that point meet to form the <em>ductus epididymis, a tangled pipe</em>
- The ductus epididymis fixes and turns into the <em>ductus deferens</em>. In domestic mammals <em>blooded mammals, testicles</em> are not in a significant body cavity, yet are encased in the <em>scrotum </em>
- The glandular structure of the testis comprises of various lobules. Every tubule is contained in one of the interims between the <em>stringy septa which reach out between the mediastinum testis and the tunica albuginea</em>, and comprises of from one to, at least three, minute tangled <em>cylinders, the tubuli seminiferi</em>
<span>The Mediastinum is the space in thoracic cavity between lungs</span>
