The correct answer is option C. Single celled organisms and soft, bone less animals. The Precambrian ear was believed to be before evolution. Meaning more plants and complex animals. Therefore, organisms were single celled during that time.
Hope I could help! :)
Answer: c. Dead organic matter will accumulate on the forest floor; plant growth will decline because of a lack of nutrients and the loss of mycorrhizal partners.
Explanation:
The fungi are the eukaryotic organisms. In nature their role is to decompose the organic matter generated after the death of the living organisms. Some of these fungi lives in symbiotic mutualistic association with the plant roots so as to provide the minerals present in the soil and in return they receive the nourishment from the plants.
The treatment of the forest ecosystem enclosed in a greenhouse with the fungicide will negativity affect the forests. As the dead organic matter will be left undecomposed which will create a large amount of biodegradable waste and in absence of the mycorrhizal partners the plants will not grow properly in the absence of vital nutrients.
Answer:
Random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.
Explanation:
Sexual reproduction adds genetic variations in the progeny by crossing over, independent segregation of homologous chromosomes and random fusion of gametes. Without crossing over, independent segregation of homologous chromosomes towards opposite poles during anaphase I of meiosis may result in two siblings to vary from each other for 0-23 chromosomes.
There is an equal probability of each of the two siblings to get a chromosome from mother or father. Hence, irrespective of the variations provided by crossing over, random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.
