Answer:
Interphase - There are 3 subphases called - G1 , S and G2 . In these subphases, DNA material is duplicated, and essential proteins for cell division are formed.
Prophase - the nuclear envelop and nucleolus disappears and condensed DNA forms chromosomes that are short in size.
Metaphase - the form of two sister chromatids are arranged in the middle of the metaphase/equatorial line. Two centrioles are found at two poles of the cell which initiate the formation of spindle fibers.
Anaphase - spindle fibers are formed and can be observed. These fibres attach with the kinetochore present in the centromere of chromosomes and these chromatids now start separated by pulling and pushing force of spindle fibers in opposite poles
Telophase - chromatids reach at destination pole and then nuclear envelop starts creating again in both poles. Nucleolus reappears and now in a cell two nucleus are found.
I would say D, but I could be wrong
Answer is: buffers.
Buffer solution is a solution<span> consisting of a </span>mixture<span> of a </span>weak acid<span> and its </span>conjugate base<span>, or weak base and its conjugate acid. Its pH changes very little when a small amount of </span>strong acid<span> or </span>base<span> is added to it. Buffer solutions keep pH at a nearly constant value.
</span>Some buffers are: ethanoic acid and sodium ethanoate, <span>ammonia solution and ammonium chloride.</span>
The complete question goes like this :
<span>Almost every major city in the world has a zoo. Humans have kept and enjoyed animals since the prehistoric times. Ancient Greeks and Romans kept small zoos. Over the past fifty years, zoos have changed remarkably. Today zoos provide the animals with larger and more natural habitats.
</span><span>Which sentence could be added to the passage as a supporting detail?
</span>The correct answer is <span>A) Zoos also provide great research facilities
This sentence is adding more information directly related to the state of the zoo in modern times. Besides the educational and entertaining purposes, the zoos are now becoming important centres for research and places for developing conservation strategies for endangered animals. All of the other sentences are not relevant to the importance and characteristic of modern-day zoos. </span>
