Answer:
1. True
2. True
3. False, they have 46
4. False, they inherit traits from both parents
5. True
6. False, rice has 12 pairs of chromsomes and flies have 4 so not all orangisms have the same number of chromosomes
7. True (not too confident with this one though)
8. False, a body cell has 46 while gametes have 23
9. False
10. True
Explanation:
It is a tectonic plate, it is constantly moving and shaping the Earth's crust.
Answer:
wast and minerals break down and reproduce.
Explanation:
such as fungi and bacteria: Fungi and bacteria help other things such as wast and minerals break down and reproduce. They are very important role of organisms. Without them our grounds would be full of trash and non broken down minerals.
Answer:
2 elements chemically joined together. An emample is Ironoxie
Explanation:
Answer:
In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species
Explanation:
A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.
