Answer:
Meiosis
Explanation:
All living organisms reproduce i.e. replicate themselves by producing young ones. However, they either do this sexually or asexually. Asexual reproduction involves the contribution of only one of the parent while sexual reproduction involves the two parent's contribution.
In sexual reproduction, a process of gamete formation called MEIOSIS occurs whereby the parental cell produces reproductive daughter cells that have a reduced number of chromosome (by half). The male and female gamete unites in sexual-reproducing organisms to form the offsprings.
Since only one parent is needed in asexual reproduction, there is no need for formation of gametes, hence, meiosis (a division only for reproductive cells) does not occur. The parent simply divides into its progeny.
Answer: Decomposers plan an important role in the biogeochemical cycling for nutrients in the environment as they are responsible for the breakdown and return of nutrients back to the environment in their native state.
Answer:
Change occurs in the heredity characteristic of living organism over time.
Explanation:
Change occurs in the heritable characteristics of living organisms with the passage of time is known as evolution. Evolution consist of three basic principles which are variation, heredity, and differential fitness. The organisms evolved with the passage of time due to change in the environmental conditions which able them to survive in that harsh climatic conditions and those which is not evolved can't survive and in the end extinction occur.
Answer: ok first you have to look at the clues or hints of what the given fossil and how many layers or solid Rock on it, now that is seen to go from the youngest to oldest age, we now know that you can design a procedure like a "Rock identification" based on what type of or rock it is for example lime stone this would tell you how far it goes back in time. Just identify the tpe of rock it is and then youll know that its that deep.
I hope this helps just wrote this from scratch for you :)
