D) Urethra is the correct answer
In meiosis, cell division will occur two times. It shall be called Meiosis I and Meiosis II. And Meiosis happens to our sex cells, egg for female and sperm cells for the male. There four stages in Meiosis I, Prophase I will happen when who homologous chromosomes exchange DNA. Metaphase I will happen when the pair move together in the center. Anaphase I is when the who homologous chromosomes are pulled apart to opposite poles. Telophase I is when the the first division of the chromosomes happen. Producing two 24 chromosomes cells. The nest division will produce haploid or 12 chromosome cells. In Propase II, the nuclear walls will disappear once again, in the Metaphase II the cells will meet again in the center. In Anaphase II the chromatids will be pulled apart. And then lastly in the Telophase II, the chromatids will not be 2 haploids. So in Meiosis, 4 sex cells are produced.
Isolation after an Event. An earthquake causes two populations to become separate from each other. Over time, each species experiences genetic makeup specific only to their own smaller, less diverse populations. ... Over time, the group becomes an entirely different species.
3 methods of irrigation are drip, surface, and sprinkler. Sprinkler irrigation applies water to soil, surface irrigation transports it to the channels where it floods the field, and drip irrigation exposes the roots to more supplies of water.
Answer:
The average speed of the fish is:
Explanation:
You must take into account that the fish swims 10 laps, so you must multiply the perimeter by 10 to obtain the total meters swam:
- 720 m * 10 = 7200 meters.
Now, you just must divide the total meters swam by the number of minutes that the fish took to do this, so:
- 7200 m / 120 min = <u>60 m/min
</u>
Remember, ever you do an exercise like this, you must check the units, I mean, the units that the exercise wants to be the same you use, in this case, the average speed of the fish is 60 m/min.
