Although ascospores are produced by mitotic division, none of the spores develop into fungi that are identical to either parenta
marusya05 [52]

Answer:

A

Explanation:

The correct answer would be that <u>the spores inherit half of their genes from each parent.</u>

<em>The ascospores start their journey through the fusion of 2 haploid nuclei (karyogamy) to form a diploid zygote nucleus. The zygote nucleus develops and then divides by meiosis to produce 4 haploid daughter cells. Each daughter cell then divides mitotically, making it eight haploid nuclei at the end.</em>

Hence, each spore inherits half of its gene from different nuclei.

The correct option is A.

Which of the following statements is FALSE regarding enzymes?
umka2103 [35]

Answer:

D) Enzymes make nonspontaneous reactions become spontaneous

Explanation:

Being spontaneous or non-spontaneous in nature depends on the difference in energy levels between substrates and products of the reactions. A reaction with substrates at higher energy levels than the products are spontaneous ones. On the other hand, the reactions wherein products have higher energy content than the substrates are non-spontaneous.  

Enzymes do not change the energy levels of substrates and products, so, they can not make a non-spontaneous reaction to become a spontaneous one. Enzymes only lower down the activation energy for a reaction and thereby make the non-spontaneous reaction to occur at a faster rate.
