Answer:
Explanation:
MEIOSIS:
- Each replicated chromosome pairs with its corresponding homologous chromosome
- Tetrads form and crossing over sometimes occur
- Paired homologous chromosome line up across the center of the cell.
- Four haploid daughter cells form that are not identical to the parent cell
MITOSIS:
- Homologous chromosomes do not pair
- One row of chromosomes line up at the center of the cell.
- The cell nucleus divides only once
- Two diploid daughter cells form that are identical to the parent cell.
hope this helped!
mark me brainliest :D
Answer:
Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Some examples of secondary succession include succession after fire, harvesting, logging, or abandonment of land or the renewal after a disease outbreak
I believe it’s the first option
this would be Prokaryotes because bacteria are single celled organisms
Answer/Explanation:
<u>Darwin's</u> <u>theory </u>of evolution refers to how the characteristics and features of a species can change over time. The process of evolution occurs due to <u>natural selection</u>. Natural selection is the mechanism by which organisms that have inherited beneficial traits are more likely to survive and undergo <u>successful reproduction</u>, meaning that variation is passed on to the next generation.
For example, in a species that suffers from overpopulation, organisms will likely have to compete for food and might <u>struggle to survive.</u> However, if a random change in the DNA sequence occurs, it could provide a beneficial effect to an organism that makes it more likely to find food and outcompete others. This makes that individual more likely to survive and reach mating age. This i<u>nheritable variation</u> could then be passed on to that individual's offspring.
