Many organisms spend most of their life cycle in the diploid state. if meiosis produces haploid cells, how is the diploid number restored for those organisms that spend most of their life cycle in the diploid state?
a) dna replication
b) reverse transcription
c) synapsis
d) fertilization

D

Explanation:

During fertilization, one gamete from one parent meets and fuses with a gamete from another parent, to form a zygote. The zygote then develops into a mature organism through embryology. Fertilization (a form of genetic recombination) is an evolutionary advantage that ensures that a population maintains genetic diversity which is important for the population  so it is able adapt to changes in the environment.

c

explanation:

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
