A nuclear power plant will use nuclear energy to power the town. While nuclear energy is perhaps one of the most effective ways to provide power, a nuclear accident is very dangerous, and could destroy an environment and its organisms. There was a nuclear accident in Chernobyl, Ukraine, in the 1900s. people had to evacuate because of it.
Cellular respiration takes place in the mitochondria
The Major function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli, the layers of the cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other, the barrier between air and blood averages about 1 micron in thickness. Oxygen diffuses quickly through the air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
Cytochromes:- They are iron containing hemoproteins that serve many cellular functions including energy production, steroid biosynthesis, and degradation of toxins.
Cytochromes occur in all organisms except a few obligate anaerobes. They are structurally similar among organisms. These are proteins to which one to two tetrapyrrole rings are bound. These tetrapyrroles are very similar to the chromophores of chlorophylls in plants. However, chlorophylls(in plants) contain Mg++ as the central atom in the tetrapyrrole, whereas the cytochromes(in aerobic animals) have an iron atom (Figure).
<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>
