Answer: Above 7

Explanation: The pH of the ocean is above 7. It has been basic foe over the past 300 million years. There has been a significant increase in the acidity of the ocean water.

The pH of the ocean water is around 8.2. The acidity  in the ocean water near the surface does not allows the shell growth in the marine animals. It is suspected to cause some sought of reproductive disorder in some fishes.

Use the mechanisms of meiosis to explain why most mules are sterile.
Tema [17]

Answer:

3. An even number of chromosomes are required for synapsis during prophase I and proper pairing during metaphase

Explanation:

Mules are hybrids of a cross between a female horse and a male donkey. Horses contain 64 chromosomes while donkeys contain 63 chromosomes in their somatic cells respectively. This means that they each produce 32 and 31 chromosomes respectively during meiosis. A mule, hence, contains 32+31= 63 chromosomes in their somatic cells.

This chromosome number in mules are uneven for meiosis to occur because meiotic division requires that an even number of homologous chromosomes pair together in a process called SYNAPSIS during prophase I of meiosis I. This is impossible in a mule because of the uneven number of chromosomes in its cells.

Also, during metaphase of meiosis, the homologous chromosomes need to be properly aligned at the equator for separation to occur. This is also impossible in a mule considering the number of chromosomes that don't add up.

Due to this reason of unevenness in the number of chromosomes present in a mule, meiosis will not occur and if meiosis (gamete formation) does not occur, reproduction cannot take place. Therefore, the mule is a sterile species i.e. cannot produce offsprings via sexual reproduction.
