Answer:
Matter cycling is the place where matter moves starting with one structure then onto the next or starting with one spot then onto the next on the earth, and inside its environments. ... Matter additionally cycles normally, and because of human action. Human exercises can cause matter cycling with positive and negative impacts on the regular world.
sorry for the wait <3
Answer:
The typical marmoset sperm cell must contain 23 chromosomes as well because when it mixes with the female chromosomes, it should add up to 46. Gametes cells always have half the amount of regular cells.
Answer:
The Grants wanted to find out whether they could see the force of natural selection at work, judging by which birds survived the changing environment. For the finches, body size and the size and shape of their beaks are traits that vary in adapting to environmental niches or changes in those niches.
Answer:
Spore
Explanation:
In the process of sexual reproduction, specialized haploid cells from two organisms, which can be called the (+) and (−) mating types, come together to produce a diploid zygote. The zygote after then will go through meiosis to produce four haploid cells termed spores. The spore, houses a new genetic combination from two parents with its capability to be dormant for varying time range.
Plants possesses a life cycle that switches between a multicellular haploid organism and a multicellular diploid organism. Take the ferns for example, both the haploid and diploid plant phases are free-living. The diploid plant is known as a sporophyte due to its ability to form haploid spores by meiosis. The spores grow into a multicellular, haploid plants termed gametophytes since they can have gametes. The gametes of two individuals will come together to produce a diploid zygote that is the sporophyte. The attached image 1 explains more on this.
Fungi, take for instance black bread mold (Rhizopus nigricans), possess haploid-dominant life cycles. The haploid multicellular stage give rise to specialized haploid cells by mitosis that come together to produce a diploid zygote. The zygote pass through meiosis to form haploid spores. Each spore will lead to a multicellular haploid organism by mitosis. The attached image 2 explains more on this.
