As temperature increases the rate of enzyme activity increases until it reaches approximately 37 degrees Celsius. As temperature
UNO [17]

Answer: Option A

<u>Explanation:</u>

As temperature increases the rate of enzyme activity increases until it reaches approximately 37 degrees Celsius. As temperature increases beyond 37 degrees Celsius, the enzyme activity decreases. The activity decreases because the enzyme denatures.

Any enzyme has certain temperature, pH and pressure to maintain its activity. Only at the ideal or ambient parameters the enzyme works. Most of the enzymes that are present in the human body gets activated by 37 degrees and gets denatured beyond that temperature.

What are the phases of meiosis where crossing over occur
ehidna [41]

Answer:

Prophase 1

Explanation:

Prophase I :It can be divided into five stages:

1)Leplotene: In this stage, chromosome becomes visible and shorten as a single structure.

2)Zygotene: Homologous / sister chromosome pair up. This process is known as synapse. Synapse is the process of attachment of homologous /sister chromosome. One pair comes from the male parent while the other comes from the female parent.

3)Pachytene: Bivalents shorten.

4)Diplotene:Point of attachment of non-sister chromatids. The two chromosomes are seen to be joined at several points along their length. These points are known as Chiasmata.(Chiasmata, a cross). The paternal gene A, B, C may swap for the maternal gene a, b, c for instance, leading to a new gene combination in the resulting chromatids. This is referred to as *CROSSING OVER*.

5)Diakenesis: Homologous centromere move apart.

So, crossing over occurs in *Prophase 1.
